Step 2: Check for Blockages
- Detach the wand and cleaner head from the main body.
- Inspect the wand, cleaner head, and hose for debris or obstructions.
- Remove any visible blockages carefully, ensuring no debris remains.
- Check the brush bar to see if tangled hair or debris is causing issues and clear as needed.
Step 3: Clean or Replace Filters
Dirty filters can cause overheating and pulsing. Remove the pre-filter and main filter from the vacuum (as per your model’s instructions). Rinse filters under cold water until clean, then let them air dry completely before reinstalling. If filters are damaged or excessively worn, replace them with compatible filters like the 3Pack Pre Filters Replacement.
Step 4: Check Battery and Connections
Ensure the vacuum’s battery is properly seated and charging. If the vacuum is not charging correctly, try cleaning the charging contacts with a dry cloth. If issues persist, the battery might need replacement or professional repair.
Step 5: Reset and Test
After cleaning filters and checking for blockages, turn on the vacuum to see if the pulsing issue persists. If it does, perform a reset by turning off, removing the battery (if removable), waiting a few minutes, then reattaching and powering on again.
