Step 2: Check for Blockages

  1. Detach the wand and cleaner head from the main body.
  2. Inspect the inlet channels, wand, and cleaner head for obstructions or debris.
  3. Remove any visible blockages carefully.
  4. Use a long, flexible brush or a straightened wire to dislodge stubborn debris.

Step 3: Clean or Replace Filters

  1. Remove the pre-filters and main filters from the vacuum.
  2. Rinse the filters under cold water until the water runs clear.
  3. Allow filters to air dry completely (at least 24 hours) before reinstalling.
  4. If filters are damaged or excessively worn, replace them with compatible replacements like the 3Pack Pre Filters or V10 Filters.

Step 4: Check Battery and Connections

Ensure the battery is securely connected and seated properly. Look for any signs of damage or corrosion on the terminals. If your vacuum has a removable battery, try reinstalling or replacing it if necessary.

Step 5: Reset the Vacuum

Press and hold the power trigger for about 10 seconds to discharge residual power. Then, reassemble the vacuum, turn it on, and see if the pulsing persists. If it does, perform a full reset by disconnecting the battery (if removable) and waiting a few minutes before reconnecting.
