Step 2: Check for Blockages

  1. Inspect the wand, cleaner head, and hose for any debris or obstructions.
  2. Remove the cleaner head and wand to look inside for blockages.
  3. Clear any debris using a long, flexible brush or a gentle stream of water (if washable).

Step 3: Clean or Replace Filters

  1. Remove the pre-filters and main filters from the vacuum.
  2. Rinse washable filters under cold water until clear, then let them air dry completely (preferably 24 hours).
  3. If filters are heavily soiled or damaged, replace them with new ones like the 3Pack Pre Filters Replacement or V10 filters.

Step 4: Check Battery and Power Settings

Ensure the battery is fully charged. If pulsing persists, try resetting the vacuum by turning it off, removing the battery if possible, then reinserting it. Also, verify that you’re using the correct power mode for the floor type.

Step 5: Perform Routine Maintenance

Regularly clean the brush bar, check for tangled hair, and empty the bin. Keeping parts clean helps prevent malfunctions and pulsing issues.
