Clean the Vacuum’s Dustbin and Cyclone

  • Empty the dustbin to remove accumulated debris that can block airflow.
  • Check the cyclone for dust buildup; clean with a soft brush or compressed air if necessary.
  • Ensure all parts are dry before reassembling to prevent moisture damage.

Inspect and Clean the Battery Contacts

Power off the vacuum and remove the battery if possible. Wipe the metal contacts with a dry cloth to remove dust or corrosion. Reinsert the battery firmly, ensuring proper connection.

Optimize Usage and Charging Habits

  • Avoid letting the battery fully discharge regularly; keep it charged between 20-80% for longevity.
  • Use the power trigger efficiently—only engage full power when necessary.
  • Charge the vacuum in a cool, dry place and avoid overcharging.

Replace Worn-Out Filters and Components

If cleaning doesn’t improve run time, consider replacing filters or other worn parts. Use compatible replacements like the 3Pack Pre Filters or V10 Filters as needed.
