Step 1: Check and Recharge the Battery

  1. Ensure the vacuum is turned off and unplugged from any charging source.

Step 2: Inspect and Clean the Filters

Clogged filters can impair airflow, making the motor work harder and draining the battery faster. Remove the pre-filters and main filters, rinse them under water, and allow them to air dry completely before reinstalling.

Step 3: Clear Blockages and Clean the Vacuum

  1. Check the wand, cleaner heads, and hose for blockages or debris.
  2. Use a soft cloth or a crevice tool to remove dust or hair buildup.
  3. Ensure all parts are dry and free of obstructions before reassembling.

Step 4: Replace Worn or Old Filters

If filters are over 2-3 months old or visibly dirty after cleaning, replace them with compatible filters like the 3Pack Pre Filters or V10 Filters. This restores suction and battery efficiency.

Additional Tips and Warnings

  • Always use genuine or compatible replacement filters to avoid damage.
  • Avoid overcharging the vacuum to prolong battery life.
  • Do not attempt to open the battery pack yourself, as it may be hazardous.
