For most Dolphin owners, I would start with the TUOWS 9991432-R4 four-pack for its targeted compatibility and convenient spares; the Ulticor ultra-fine basket is a standout for finer debris, while the Polaris 280/480 mesh bag fits buyers with a pressure-side cleaner. The right replacement filter for an automatic pool cleaner depends first on the exact cleaner model, then on whether you need a cartridge, basket, sponge, or debris bag. Finer filtration can catch smaller particles but may need more frequent cleaning, while mesh bags and coarser elements suit larger debris and simpler upkeep. Pack size, fit, and replacement cost also shape the choice. Read on for the full comparison and buying advice.

Key Takeaways
- Cleaner model compatibility separates these picks more than pack size: Dolphin, Hayward, WYBOT, Aiper, Polaris, and Ray-Vac parts are not interchangeable just because they look similar.
- The Dolphin-focused options split into distinct roles: TUOWS 9991432-R4 offers a practical four-pack, Henkgo and Poolzilla emphasize ultra-fine panels or cartridges, and Ulticor uses a basket format.
- The Aiper Scuba S1 3 µm inserts target very fine debris, but finer media can load faster and call for more frequent rinsing than a general-purpose filter.
- Bag-style replacements for Pentair Legend, Polaris 280/480, and Zodiac Jandy Ray-Vac serve different cleaner designs; matching the attachment and opening matters as much as the fabric.
- Several listings cover similar cleaner families, including two Hayward RCX70101 options and two Ray-Vac energy elements, so buyers should compare part numbers and pack contents rather than relying on a broad compatibility label.

More Details on Our Top Picks
KTWT RCX70101 Robotic Pool Cleaner Filter Cartridges (2 Pack) – Replacement for Hayward AquaVac, TigerShark, and SharkVac
For owners of a compatible Hayward AquaVac, TigerShark, or SharkVac, this two-cartridge set focuses on a durable, reusable replacement rather than broad model coverage. Its diamond-grid PET fiber is designed to handle repeated rinsing and regular debris collection, while the plastic frame supports frequent handling. Compared with the TUOWS Dolphin 9991432-R4 four-pack, this set supplies fewer cartridges, but it serves a different cleaner family and includes a listed one-year warranty. That limited fit is the main tradeoff: it is not a flexible choice for households with another brand or an unlisted Hayward model. The cartridges are described as tool-free to install and rinse clean, making them a practical spare set for owners who have confirmed their cleaner uses RCX70101 filters.
Pros:- Compatible with several named Hayward robotic cleaner families
- Reusable PET fiber cartridges with a diamond-grid design
- Two cartridges let owners keep a spare available
- Listed one-year warranty
Cons:- Compatibility is limited to specified Hayward models
- Includes two cartridges, fewer than the four-filter TUOWS Dolphin pack
- The product data does not specify a filtration micron rating
Best for: Hayward robotic-cleaner owners with an AquaVac, TigerShark, or SharkVac model that takes RCX70101 cartridges and who want reusable spares.
Not ideal for: Owners of Dolphin, WYBOT, Pentair, or Polaris cleaners, and Hayward owners who have not verified RCX70101 fit.
- Model number:RCX70101PAK2
- Compatibility:Hayward AquaVac, TigerShark, and SharkVac
- Quantity:2 cartridges
- Material:Enhanced PET fiber with diamond grid
- Dimensions:11.4 × 0.6 × 6.6 inches
- Item weight:9.2 ounces
- Manufacturer:KTWT
- Warranty:1 year
Our verdict“Choose this set if your compatible Hayward cleaner takes RCX70101 cartridges and you value reusable construction over a larger pack.”
TUOWS 9991432-R4 Replacement Pool Filter Cartridges, 4-Pack, Compatible with Dolphin M400/M500 and Nautilus CC Plus
This is the lineup’s higher-quantity cartridge option for owners of a Dolphin M400, M500, or Nautilus CC Plus. Four reusable-style PET fiber filters give a household more replacements on hand than the KTWT Hayward two-pack, which can help when filters need rotating or one is damaged. The diamond-grid construction is intended to balance filtration with resistance to impact during cleaning and handling. Fit, however, is unusually specific: the listing excludes the Nautilus CC and Nautilus CC Pro, so a similar model name is not enough to confirm compatibility. Unlike the WYBOT A1 foam sponges in this roundup, these are cartridges for named Dolphin models, not a general-purpose filter material. I’d shortlist this pack only after checking the cleaner’s exact model and filter reference.
Pros:- Four cartridges provide more spares than the KTWT Hayward two-pack
- Enhanced PET fiber construction
- Diamond-grid design is intended to resist impact
- Fits three specified Dolphin cleaner models
Cons:- Explicitly incompatible with Nautilus CC and Nautilus CC Pro
- Does not include cartridges for other cleaner brands
- The product data gives no filtration micron rating
Best for: Owners of a Dolphin M400, M500, or Nautilus CC Plus who want several replacement cartridges ready for rotation.
Not ideal for: Nautilus CC or Nautilus CC Pro owners, or anyone whose Dolphin model is not listed as compatible.
- Model:9991432-R4
- Quantity:4 filters
- Compatible models:Dolphin M400, Dolphin M500, and Nautilus CC Plus
- Incompatible models:Nautilus CC and Nautilus CC Pro
- Material:Enhanced PET fiber
- Dimensions:6 × 3 × 2 inches
- Item weight:15.2 ounces
- Manufacturer:TUOWS
Our verdict“Pick this four-pack if you have a confirmed compatible Dolphin model and want multiple cartridge replacements on hand.”
8-Pack Cotton Foam Replacement Filter Sponges for WYBOT A1 Robotic Pool Cleaner
These replacement filters take a different form from the cartridge sets: they are cotton foam sponges made specifically for the WYBOT A1. The pack of eight is the largest replacement count among the products in this batch, so it suits owners who want several spares ready rather than stretching a small set through repeated use. Rinsing with water and replacing without tools also keeps routine upkeep simple. Compared with the KTWT Hayward cartridges or TUOWS Dolphin cartridges, these sponges are not interchangeable with those systems, and the listing does not provide a filtration rating or debris-size claim. Their value depends almost entirely on confirmed WYBOT A1 ownership. Buyers with another cleaner should skip them, even if the sponge dimensions appear close.
Pros:- Eight sponges provide a large supply of replacements
- Cotton foam can be rinsed and reused
- Tool-free replacement
- Lightweight set at 3.17 ounces
Cons:- Designed only for the WYBOT A1
- Foam sponge format differs from the cartridge filters used by Hayward and Dolphin models
- No filtration micron rating is supplied
Best for: WYBOT A1 owners who want a sizeable supply of washable, tool-free replacement sponges.
Not ideal for: Owners of any cleaner other than the WYBOT A1, or buyers seeking cartridge-style filters or a stated filtration rating.
- Model:DHRTTE
- Quantity:8 filter sponges
- Material:Cotton foam
- Compatibility:WYBOT A1 robotic pool cleaner
- Dimensions:9 × 0.3 × 9 inches
- Item weight:3.17 ounces
- Color:White
Our verdict“Choose these sponges if you own a WYBOT A1 and prefer a plentiful, rinse-clean replacement supply.”
Zippered Fine Mesh Debris Bag for Pentair Legend Pool Cleaners
Unlike the cartridge replacements for Hayward and Dolphin robots, this is a fine mesh debris bag for compatible Pentair Kreepy Krauly Legend, Platinum, and Letro cleaners. Its zipper opening is a practical advantage when emptying leaves, hair, paper, and other collected debris: the bag can be opened without pulling material back through a narrow mouth. A rubber opening plate and Velcro tie also help keep the bag seated and upright during operation. The Polaris 280/480 nylon bag in this roundup serves a similar collection role, but it fits a different cleaner family and uses reinforced stitching and a clip. This Pentair option is a one-bag purchase, and its fine mesh may take more effort to clean when debris is wet. Confirm model fit before ordering.
Pros:- Fine mesh collects leaves, hair, paper, and other common debris
- Zipper closure gives access for emptying
- Rubber plate and Velcro tie help stabilize the bag
- Tool-free installation and reusable construction
Cons:- Fits only specified Pentair cleaner families
- One bag is included
- Wet debris can make cleaning more difficult
Best for: Owners of compatible Pentair Legend, Platinum, or Letro cleaners who want a reusable bag with a zipper and stabilizing tie.
Not ideal for: Owners of Polaris, robotic cartridge-based cleaners, or Pentair models outside the listed families.
- Compatible models:Pentair Kreepy Krauly Legend, Platinum, and Letro pool cleaners
- Material:Polyester fabric with rubber plate
- Closure:Zipper
- Load capacity:5 pounds
- Item weight:0.17 kg
- Color:White
- Number of items:1
- Brand:JUNPENG
Our verdict“Choose this bag if your compatible Pentair cleaner needs reusable fine-mesh debris collection with a secure zipper closure.”
Nylon Mesh Pool Cleaner Bag for Polaris 280 and 480
For a Polaris 280 or 480, this replacement bag emphasizes a tight fit and reinforced construction over a multi-part closure system. Its nylon mesh is designed to collect leaves, small twigs, and other debris, while reinforced stitching is intended to reduce tearing during repeated use. The wide zipper opening makes emptying more direct than a simple open-mouth bag, and the enhanced clip helps secure it to the cleaner. Compared with the JUNPENG Pentair fine mesh bag, this one serves a different cleaner family and highlights clip fit and stitching rather than a rubber plate and Velcro tie. Its biggest limitation is narrow compatibility; it is not a substitute for robotic cartridges or Pentair bags. Confirm your Polaris model before choosing it.
Pros:- Tightly woven nylon mesh collects leaves and small twigs
- Reinforced stitching is designed to resist tearing
- Wide zipper opening simplifies emptying
- Enhanced clip supports a secure fit
Cons:- Compatibility is limited to Polaris 280 and 480
- Does not replace cartridge or sponge filters used by robotic cleaners
- The product data does not state a debris load capacity
Best for: Polaris 280 and 480 owners who need a reusable debris bag with a zipper, reinforced seams, and a securing clip.
Not ideal for: Owners of other Polaris models, Pentair cleaners, or automatic robotic cleaners that use cartridges or filter panels.
- Material:Nylon
- Color:White
- Compatibility:Polaris 280 and 480
- Bag type:All-purpose, zippered
- Power source:Suction powered
- Installation type:Pressure side
- Dimensions:13.3 × 9 × 2.7 inches
- Weight:0.17 kg
Our verdict“Pick this bag if you own a Polaris 280 or 480 and want a zippered, reinforced replacement for collecting larger debris.”
2-Pack 3 µm Filter Inserts for Aiper Scuba S1 Pool Cleaner
For owners of the standard or upgraded Aiper Scuba S1, these inserts focus on very fine debris: the stated 3 µm filtration targets silt and sand that coarser filters may leave behind. The snap-in, tool-free fit makes replacement straightforward, and silicone edging is intended to resist tearing during handling. Compared with the Henkgo Dolphin panels, this is a much narrower model-specific purchase rather than a broadly compatible pack, but it offers a clearly stated filtration fineness. The key tradeoff is that the white frame is not included, so buyers need a suitable existing frame. It also does not fit the Aiper Scuba S1 Pro; checking the cleaner model before ordering matters more here than choosing by brand alone.
Pros:- Stated 3 µm fineness targets very fine debris such as silt and sand
- Snap-in installation requires no tools
- Two inserts provide a spare for the next replacement
- Silicone edging is designed to resist tearing
Cons:- Does not fit the Aiper Scuba S1 Pro
- White frame is not included
- Compatibility is limited to specified Scuba S1 versions
Best for: Aiper Scuba S1 standard or upgraded owners whose pools collect fine silt or sand and who already have the compatible white frame.
Not ideal for: Aiper Scuba S1 Pro owners, or anyone who needs a complete filter assembly rather than replacement inserts.
- Quantity:2 filter inserts
- Filter fineness:3 µm
- Compatible models:Aiper Scuba S1 standard and upgraded models
- Excluded model:Aiper Scuba S1 Pro
- Installation:Snap-in, tool-free
- Frame:White frame not included
- Edge material:Silicone
Our verdict“Choose these inserts for fine silt in a compatible Scuba S1 when you can reuse the existing frame; skip them for the S1 Pro or a complete assembly.”
Henkgo Ultra-Fine Filter Panels for Dolphin Robotic Pool Cleaners, 4-Pack
The Henkgo pack suits Dolphin owners who want four washable panels for a long list of compatible cleaners, including several Active, Explorer, M, S, and Triton variants. Its fit is tied to replacement part 9991467-R4, so the extensive model list is useful only if it matches the cleaner in your pool. Numbered panels help guide installation, a practical difference from Poolzilla’s 9991432-R4 cartridges, which serve a different set of Dolphin models. The pleated panels are made to capture fine dirt and can be rinsed with a garden hose, avoiding disposable-filter replacement. The tradeoff is routine cleaning: debris must be rinsed away, and buyers should verify the exact model rather than assume that any Dolphin cleaner is compatible.
Pros:- Four washable, reusable panels in one pack
- Fits a broad range of specified Dolphin cleaner models
- Numbering helps guide panel installation
- Pleated design is intended to capture fine dirt and debris
Cons:- Model compatibility must be checked carefully
- Collected debris requires rinsing after use
- Fits part 9991467-R4, not every Dolphin filter system
Best for: Dolphin owners with a cleaner listed for part 9991467-R4 who want multiple reusable panels and clearer installation guidance.
Not ideal for: Owners of Dolphin models outside the listed compatibility range, or buyers whose cleaner requires the 9991432-R4 cartridge instead.
- Brand:Henkgo
- Model:GLW-A1
- Replacement part number:9991467-R4
- Quantity:4 filter panels
- Material:Plastic
- Dimensions:9 × 8 × 2.1 in
- Weight:0.48 kg
- Care:Washable and reusable; rinse with a garden hose
- Compatible models:Specified Dolphin Active, Advantage Ultra, Discovery, Explorer, M, Mercury, Premium, Proteus, Prowler, Quantum, S, T, Triton, and Warrior models
Our verdict“Pick Henkgo when your Dolphin uses 9991467-R4 and you value a reusable four-panel set; choose a different cartridge for models requiring 9991432-R4.”
Poolzilla Ultra-Fine Pool Cleaner Filter Cartridges (4-Pack), Compatible with Dolphin 9991432-R4
Poolzilla is the more targeted choice for Dolphin owners whose cleaner takes part 9991432-R4. The four ultra-fine pleated cartridges are sized at 10.5 × 6.375 inches and are intended to catch small particles, with water rinsing described as the routine cleaning method. Compared with Henkgo’s 9991467-R4 panels, this pack serves a different model family, so the part number—not the shared Dolphin name—should drive the decision. Its compatibility list includes models such as the Nautilus CC Plus, M-series cleaners, and several Wave cleaners, while older Nautilus, Nautilus CC, Triton, and specified Triton PS models are excluded. The main tradeoff is that it is a third-party replacement, and its wide list still demands a precise model check.
Pros:- Four ultra-fine pleated cartridges for the specified filter system
- Compatible with a range of listed Dolphin models
- Water rinsing provides a simple cleaning routine
- Dimensions and replacement part number help with fit checks
Cons:- Not compatible with several older Nautilus and Triton models
- Third-party replacement rather than an OEM part
- Requires careful model and part-number verification
Best for: Dolphin owners with a cleaner listed for 9991432-R4 who want four reusable, fine-particle cartridges.
Not ideal for: Owners of excluded Nautilus or Triton models, or Dolphin users whose cleaner takes 9991467-R4 panels.
- Brand:Poolzilla
- Quantity:4 cartridges
- Compatible part number:9991432-R4
- Dimensions:10.5 × 6.375 in
- Filter design:Ultra-fine pleated cartridges
- Compatible models:Aquarius XL, Bio, C3, C4, Nautilus CC Plus, Nautilus CC Supreme, Triton Plus, Oasis Z5/Z5i, Sigma, Supreme M4/M5, Dolphin M200/M400/M500, Wave 60/65/80/90
- Incompatible models:Nautilus (old), Nautilus CC, Triton, Triton PS, Triton PS Plus
- Care:Rinse with water
Our verdict“Choose Poolzilla for a Dolphin cleaner confirmed to use 9991432-R4; Henkgo is the relevant alternative when your cleaner instead takes 9991467-R4.”
Energy Filter Element for Zodiac Jandy Ray‑Vac Pool Cleaner
This element fills a different niche from the robotic-cleaner cartridges in this roundup: it is made for the Zodiac Jandy Ray-Vac, with the listed model number R0374600. Its concave-convex mesh design is intended to capture debris, while its compact 3 × 3 × 5-inch form suits this specific cleaner assembly. Unlike the Hayward cartridges, which come as a two-pack and fit several robotic cleaner families, this is a dedicated replacement element for Ray-Vac owners. That specificity is its advantage only when the model matches. The supplied details do not list a pack quantity or a removal tool, and the small element can make replacement fiddly. Buyers should confirm the part number and be prepared for careful installation rather than expect a broad-fit cartridge swap.
Pros:- Specified for Zodiac Jandy Ray-Vac pool cleaners
- Concave-convex mesh design is intended to capture debris
- Compact listed dimensions suit the dedicated element format
- Designed as a replacement for model R0374600
Cons:- Small size can make replacement fiddly
- No dedicated removal tool is included
- Compatibility is limited to the specified Ray-Vac application
Best for: Zodiac Jandy Ray-Vac owners replacing the R0374600 energy filter element in a compatible cleaner.
Not ideal for: Owners of robotic cleaners from Hayward, Dolphin, or Aiper, and Ray-Vac users who need a larger or tool-assisted replacement component.
- Manufacturer:Etotel
- Model number:R0374600
- Compatible cleaner:Zodiac Jandy Ray-Vac
- Dimensions:3 × 3 × 5 in
- Weight:3.84 oz
- Filter design:Concave-convex mesh
Our verdict“Choose this element when your Ray-Vac requires R0374600; it is not a substitute for the broader cartridge packs made for robotic cleaners.”
Replacement Robotic Pool Cleaner Filter Cartridges (2 Pack) for Hayward TigerShark, SharkVac, and AquaVac
For owners of compatible Hayward robotic cleaners, this two-pack combines ABS frames with thickened PET fiber mesh, a more rigid cartridge construction than the loose filter inserts used in the Aiper Scuba S1 pack. The filters are reusable and designed for ultra-fine filtration, so they can be cleaned rather than discarded after a pool cycle. Their stated fit covers TigerShark, SharkVac, and AquaVac models, but the part number and exact cleaner version still deserve a check before ordering. Compared with Poolzilla’s four-pack for select Dolphin cleaners, this set contains fewer cartridges and serves a different brand family. It also calls for periodic flushing, listed at every 4–6 weeks, so buyers seeking minimal maintenance may prefer a filter system with a simpler cleaning schedule.
Pros:- Fits the specified Hayward TigerShark, SharkVac, and AquaVac cleaner families
- ABS frame and PET fiber mesh provide a structured cartridge design
- Reusable construction allows cleaning and reuse
- Two cartridges are included
Cons:- Exact model fitment should be checked before purchase
- Requires regular flushing, listed every 4–6 weeks
- Two-pack provides fewer cartridges than Poolzilla’s four-pack
Best for: Hayward TigerShark, SharkVac, or AquaVac owners who need reusable cartridges with a framed construction and have confirmed the fit.
Not ideal for: Dolphin, Aiper, or Ray-Vac owners, and Hayward buyers who need more than two cartridges or do not want scheduled flushing.
- Part number:RCX70101PAK2
- Quantity:2 cartridges
- Materials:ABS plastic frame and PET fiber mesh
- Compatible models:Hayward TigerShark, SharkVac, and AquaVac
- Item weight:11.7 oz
- Package dimensions:12.2 × 6.97 × 1.65 in
- Manufacturer:FLN
- Maintenance:Reusable; flush every 4–6 weeks as specified
Our verdict“Choose this pack for a confirmed compatible Hayward cleaner and reusable framed cartridges; skip it if your cleaner is from another lineup or you want a larger set.”
TTEEWIIG Energy Filter Element R0374600 for Zodiac Jandy Ray-Vac Pool Cleaner
This is the most targeted choice in this group: the R0374600 replacement element is specified for the Zodiac Jandy Ray-Vac, with nylon and polypropylene construction intended to catch sediment and rust. Its compact dimensions and 5.3-ounce weight suit buyers replacing that particular cleaner’s energy filter, rather than seeking a general-purpose cartridge. Compared with the four-pack RCX70101PAK2 cartridges from TUOWS, this is a single, model-specific part, not a multi-cartridge supply for Hayward cleaners. The stated resistance to cracking may appeal to owners who prioritize a durable replacement, but the product data does not give a cleaning interval or broader fit list. Check the cleaner model and R0374600 part number before ordering; a close-looking filter is not enough to establish compatibility.
Pros:- Specified as a direct replacement for part R0374600
- Nylon and polypropylene construction is described as resistant to cracking
- Designed to filter sediment and rust
- Compact 3.1 x 3.1 x 5.8-inch form
Cons:- Compatibility is limited to the Zodiac Jandy Ray-Vac listing and needs model verification
- One element is listed, unlike the four-cartridge TUOWS RCX70101PAK2 pack
- No cleaning interval or reusable-care instructions are provided
Best for: Zodiac Jandy Ray-Vac owners replacing the R0374600 energy filter and seeking a nylon-and-polypropylene element for sediment and rust.
Not ideal for: Owners of Dolphin, Hayward, PoolMr, or Ray cordless robotic cleaners, since this element is specified for the Jandy Ray-Vac only.
- Part number:R0374600
- Compatibility:Zodiac Jandy Ray-Vac automatic pool cleaner
- Material:Nylon and polypropylene (PP)
- Dimensions:3.1 x 3.1 x 5.8 inches
- Item weight:5.3 ounces
- Manufacturer:TTEEWIIG
Our verdict“Choose this element if your Jandy Ray-Vac calls for R0374600; skip it if you need a multi-pack or a filter for another cleaner family.”
RCX97417SPAK2 Door Filter Element for Pool Cleaners, 4 Pack
The main draw here is straightforward: four filter elements are included for buyers who already know their cleaner uses part RCX97417SPAK2. The elements are described as capturing sediment and other impurities, but the listing supplies little about the cleaner models they fit, their material, or how to maintain them. That makes this a narrower-information choice than the TUOWS RCX70101PAK2, which names several compatible Hayward series and describes its three-layer polyethylene construction. It also differs from TTEEWIIG’s R0374600 element, whose listing identifies a specific Ray-Vac cleaner. The four-pack is useful when matching the part number is enough to confirm fit, but the near-zero listed dimensions do not provide practical sizing guidance. Verify the part number against your cleaner or existing filter before buying.
Pros:- Includes four filter elements
- Designed to capture sediment and other impurities
- Part number is provided for matching against an existing element
- Offers multiple replacements in one package
Cons:- Cleaner compatibility is not specified beyond the part number
- Listed dimensions of 0.01 x 0.01 x 0.01 inches are not useful for checking fit
- Material and cleaning or reuse guidance are not provided
Best for: Pool-cleaner owners who have confirmed RCX97417SPAK2 is the correct door filter element and want four replacements on hand.
Not ideal for: First-time replacement buyers who need a clear compatibility list, material details, or usable dimensions to identify the right filter.
- Part number:RCX97417SPAK2
- Package quantity:4 filter elements
- Listed dimensions:0.01 x 0.01 x 0.01 inches
- Item weight:0.317 ounces
- Brand:Basdures
- Filter purpose:Captures sediment and other impurities
Our verdict“Buy this pack only if RCX97417SPAK2 is already confirmed for your cleaner; choose a better-documented option if you still need to establish fit.”
Reusable Pool Cleaner Filter Sponges for PoolMr and Ray Cordless Robotic Cleaners, 5-Pack
These filters stand apart from the cartridge and basket replacements in this lineup: the five high-density cotton sponge filters are washable and reusable, so buyers can rinse and return them to compatible cleaners rather than treating each replacement as a disposable cartridge. The listing says they capture fine debris, dust, leaves, and small particles, and tool-free installation makes routine swapping simpler. Compared with the Ulticor Dolphin basket, this is a sponge set for PoolMr and Ray cordless robotic cleaners, not a basket-style replacement for select Dolphin models. That dedicated fit is also the main limitation: owners of other cleaner brands should not assume these will fit. The listing does not provide dimensions or a cleaning schedule, so check the cleaner’s filter design and confirm the model before relying on the snug-fit claim.
Pros:- Five filters included
- Washable and reusable high-density cotton sponge construction
- Designed to capture fine debris, dust, leaves, and small particles
- Tool-free installation and a snug fit are described
Cons:- Compatibility is limited to PoolMr and Ray cordless robotic cleaners
- No filter dimensions are provided for fit comparison
- No cleaning interval or service-life guidance is listed
Best for: PoolMr and Ray cordless robotic cleaner owners who want washable sponge filters for repeated use and tool-free replacement.
Not ideal for: Owners of Dolphin, Hayward, or other robotic cleaners, or buyers who need published dimensions and a defined maintenance schedule.
- Quantity:5 filters
- Material:High-density cotton sponge
- Compatibility:PoolMr and Ray cordless robotic pool cleaners
- Special feature:Washable and reusable
- Installation:Tool-free
- Color:White

Ulticor Ultra-Fine Filter Basket for Select Dolphin Robotic Pool Cleaners
The Ulticor is the lineup’s clearest choice for Dolphin owners seeking an ultra-fine basket rather than replacement cartridges or loose sponges. Its stated microfiltration approach suits buyers focused on catching smaller particles, and the compatibility list covers select models such as the S50, S100, Active 10 and 15, and Nautilus CC. That model detail gives buyers more to work with than the RCX97417SPAK2 listing, which supplies only a part number. Fit still needs care: this basket is not compatible with the Nautilus CC Pro or CC Supreme, and older Active 10 or S50 units may need a plastic piece removed. The specified rinse-and-clean interval of every four to six weeks adds a maintenance task. Confirm both model and basket fit before choosing it over the reusable PoolMr and Ray sponge set.
Pros:- Ultra-fine basket uses microfiltration technology
- Compatibility is listed for several select Dolphin models
- Cleaning interval is specified as every 4–6 weeks
- Basket format is distinct from the sponge and cartridge replacements in this group
Cons:- Not compatible with Nautilus CC Pro or Nautilus CC Supreme
- Older Active 10 or S50 models may require removal of a plastic piece
- Aftermarket fit must be checked against the exact cleaner model
Best for: Owners of listed Dolphin models who want an aftermarket ultra-fine filter basket and can follow the stated cleaning schedule.
Not ideal for: Nautilus CC Pro or CC Supreme owners, or buyers of older Active 10 and S50 cleaners who are unwilling to check the noted fit modification.
- Type:Aftermarket replacement ultra-fine filter basket
- Compatibility:Select Dolphin models including S50, S100, Active 10 and 15, and Nautilus CC
- Not compatible with:Nautilus CC Pro and Nautilus CC Supreme
- Cleaning interval:Every 4–6 weeks
- Older-model fit note:Older Active 10 or S50 models may require removal of a plastic piece
- Filtration method:Microfiltration technology
Our verdict“Pick this basket for a confirmed compatible Dolphin model when fine filtration is the priority, but avoid it for excluded models or uncertain fit.”
TUOWS RCX70101PAK2 Replacement Pool Filter Cartridges, 4-Pack
For owners of the named Hayward cleaner families, this four-pack makes the most sense when a multi-cartridge supply matters more than a universal fit. Its three-layer polyethylene fiber and diamond-grid construction are intended to combine filtration with impact resistance, while the compatibility list spans TigerShark, SharkVac, and AquaVac models. Compared with the Basdures RCX97417SPAK2 four-pack, TUOWS gives buyers a much clearer model list and more construction detail; unlike the Dolphin-focused Ulticor basket, it is a cartridge replacement for select Hayward cleaners. The tradeoff is that fit is still limited to the listed series, so brand alone is not enough to confirm compatibility. These cartridges also require periodic rinsing and soaking, and the listing does not set a specific care interval.
Pros:- Four cartridges included
- Three-layer polyethylene fiber construction with a diamond-grid pattern
- Compatibility lists several TigerShark, SharkVac, and AquaVac models
- Designed for filtration and impact resistance
Cons:- Fit is restricted to the listed cleaner models
- Periodic rinsing and soaking are required
- No specific cleaning interval is provided
Best for: Owners of listed TigerShark, SharkVac, or AquaVac cleaners who want four PE cartridges with specified layered construction.
Not ideal for: Dolphin, Zodiac, PoolMr, or Ray cleaner owners, and buyers seeking a defined rinse schedule or a filter for an unlisted Hayward model.
- Model:RCX70101PAK2
- Quantity:4 cartridges
- Material:Polyethylene (PE)
- Construction:Three-layer fiber with diamond-grid pattern
- Compatible cleaners:TigerShark, TigerShark QC, TigerShark Plus, TigerShark2, TigerShark2 Plus, SharkVac XL, SharkVac, Aqua Vac 500 Series
- Weight:0.54 kg
- Color:White
- Installation type:Robotic
- Brand:TUOWS
Our verdict“Choose this pack if your exact Hayward model appears on the compatibility list and you want multiple layered cartridges in reserve.”
How We Picked
I ranked these replacement filters for automatic pool cleaners by how clearly each option identifies its cleaner fit, how its filtration format matches a likely debris need, and how practical it appears to maintain and replace. I also weighed pack size and the usefulness of each product’s distinct format—cartridge, panel, basket, sponge, or bag—without treating more pieces or finer filtration as automatic advantages. The first priority is a credible model and part-number match, since a filter that does not seat correctly cannot do its job.
The order favors options with a clear, useful role and a reasonable balance of fit, filtration, and upkeep. Compatible Dolphin cartridge replacements rank near the top for their broad relevance to common models, while specialized inserts and cleaner-specific bags follow for buyers whose equipment or debris needs call for them. Similar listings are separated by their stated model range and format, not by assumptions about unverified performance. Before ordering, I recommend checking the cleaner’s manual and existing filter part number against the listing.
Factors to Consider When Choosing Replacement Filters For Automatic Pool Cleaners
Choosing a replacement is less about finding the finest filter on the page and more about matching the part to the cleaner, debris, and maintenance routine you can keep up with. These broader checks can prevent a mismatch and help you decide when a specialized filter earns its place.
Match the Cleaner and Part Number Before Comparing Filtration
Start with the cleaner’s full model number and, when available, the part number printed on the old filter or listed in the manual. Product titles often group several cleaner families together, but a shared brand does not mean the filters fit across models. Check the shape, locking points, door or lid arrangement, and connection style against your current part. If a listing gives a compatibility range without naming your exact model, verify it with the manufacturer’s parts diagram before buying. A precise fit is more useful than a more specialized filter that cannot seal or latch correctly.
Choose Filtration for the Debris You Actually Have
Fine media is useful for small particles such as fine dust, but it can collect debris quickly and may need more frequent rinsing. A coarser cartridge or mesh bag can be a better everyday choice when the main problem is leaves, insects, or larger grit. Pool conditions change, so think about the debris that most often returns after a cleaning cycle rather than choosing the smallest micron figure alone. A highly fine filter can also be a poor match if your cleaner is already struggling with flow or if you rarely clean the filter between runs. When the pool has mixed debris, a general-purpose element may be easier to live with than a specialist insert.
Do Not Treat Cartridges, Baskets, Sponges, and Bags as Interchangeable
The filter format is tied to the cleaner’s design, not simply to filtration preference. Cartridges and panels sit in designated housings, a basket may replace a specific collection chamber, and bags attach to cleaners built to pull debris into a bag. Sponge elements can be convenient for their intended cordless models, but their shape and density still need to match the original setup. Before choosing based on easy cleaning or material, confirm how the part is installed and removed. Switching formats is only possible when the cleaner’s manufacturer specifies that option.
Balance Pack Size Against Replacement Frequency
Multi-packs are helpful when filters wear out regularly, when you want a clean spare ready, or when your pool sees heavy use. They are less useful if the cleaner model may change soon or if you are still confirming fit. Compare the number of complete filter elements in the package, not just the count stated in the title; some listings may count inserts or panels rather than full assemblies. A spare can reduce downtime, but it does not remove the need to rinse and inspect each filter. Buy a larger pack when you have verified compatibility and expect to use the extra pieces.
Plan for Cleaning and Wear, Not Just Initial Fit
Filter media needs routine rinsing, and trapped debris left in place can restrict flow or make the cleaner work harder. Fine fabric, foam, mesh, and rigid cartridge surfaces can each require different handling, so follow the product’s cleaning instructions rather than assuming every element can be scrubbed or pressure-washed. Inspect seams, frames, clips, and attachment points for damage when cleaning; a torn bag or warped cartridge may let debris bypass the filter. If upkeep is already a challenge, favor a format that is easy to remove and rinse for your cleaner. A filter that suits your maintenance habits is more likely to stay effective.
Pay More Only for a Useful Difference
A premium or ultra-fine option makes sense when your pool’s debris problem calls for finer capture or when its basket or cartridge design improves handling for your specific cleaner. It may be wasted effort if the pool mostly collects leaves or if the finer media clogs before a cleaning cycle ends. For a basic replacement, exact fit and sound construction matter more than claims that do not explain the cleaner compatibility or filtration purpose. Beginners can reduce risk by matching the original part number and format instead of experimenting with a new media type. Consider a specialized option after you know what your current filter fails to catch.
Frequently Asked Questions
How do I know which replacement filter fits my automatic pool cleaner?
Find the cleaner’s exact model number on its label, then check the manual or parts diagram for the filter’s part number. Compare that number with the replacement listing and verify the listed model range, not just the brand name. If you no longer have the original part number, compare the filter’s shape, dimensions, clips, and opening with the part being sold. Ask the seller or manufacturer to confirm fit when a listing names only a broad family. A close visual match is not a substitute for confirmed compatibility.
Should I choose an ultra-fine filter or a standard replacement?
Choose ultra-fine media when small particles are the debris you need to capture and your cleaner supports that filter type. Fine filtration can load more quickly, so it may require more frequent rinsing and can be inconvenient in a pool with heavy leaf or dirt loads. A standard filter is often more practical when most debris is visible and larger. Check the cleaner manual for approved filter options before changing filtration levels. If you are unsure, matching the original filter is the lower-risk starting point.
Can I use a Polaris, Dolphin, or Hayward filter in a different cleaner from the same brand?
Not unless the replacement listing or manufacturer’s parts information names that exact cleaner model as compatible. Brand families can include different housings, attachment points, and filter formats. Even similar-looking models may use different cartridges, bags, baskets, or door elements. Compare the part number and the physical mounting design before ordering. A part made for another model can fail to seat properly and allow debris to bypass the filter.
Is a multi-pack a better choice than buying one replacement filter?
A multi-pack is useful when you have confirmed the fit and expect to need spares, especially if the cleaner runs often or the filter wears through regular cleaning. It also lets you keep a clean element ready while another is drying. A single replacement can make more sense if you are uncertain about compatibility or still deciding between standard and fine filtration. Read the package details to determine whether the count refers to complete filters or separate inserts. Avoid stocking up until the cleaner model and part number are clear.
When should I replace a pool cleaner filter instead of cleaning it?
Rinse the filter after use or as directed, then inspect it for tears, broken seams, damaged clips, warped frames, or persistent clogging. If debris passes through despite correct installation, or the cleaner’s flow remains poor after a thorough rinse, the element may be worn or damaged. Staining alone does not always mean the filter needs replacement, but deteriorated material or a failed seal does. Follow the filter maker’s care guidance, since aggressive scrubbing or high-pressure washing can damage some media. Replacing a compromised filter is preferable to continuing to run a cleaner with poor debris capture.
Conclusion
For the broadest balance of fit and everyday usefulness, I would choose the TUOWS 9991432-R4 four-pack for a compatible Dolphin M400, M500, or Nautilus CC Plus. The KTWT RCX70101 two-pack is my value-minded pick for owners of the listed Hayward AquaVac, TigerShark, and SharkVac cleaners, while the Ulticor ultra-fine basket is the premium choice for eligible Dolphin models when finer debris capture is the priority. Beginners should stick with a replacement that matches the original part number and filter format; the Hayward or Dolphin options here make sense only when the exact cleaner is confirmed. For specific needs, choose the Aiper 3 µm inserts for the compatible Scuba S1, the Polaris mesh bag for a 280 or 480, or a Ray-Vac energy element for the listed Jandy cleaner. In every case, confirm the cleaner model and part number before ordering.
