2. Clean and Maintain Filters and Air Path

  • Remove the pre-filters and filters, rinse them with water, and let them dry completely before reinstalling.
  • Dirty filters restrict airflow, causing the motor to work harder and drain the battery faster.
  • Check the cleaner heads for blockages or tangled hair, and clear debris to maintain optimal suction and efficiency.

3. Inspect and Clean Contacts and Motor Area

  1. Turn off the vacuum and disconnect from power.
  2. Use a dry cloth or soft brush to clean contact points between the battery and vacuum body.
  3. Remove any dust or debris from the motor area, ensuring smooth operation and good electrical contact.

4. Optimize Usage and Charging Habits

  • Avoid using the highest power mode unnecessarily; switch to eco mode if suitable.
  • Charge the vacuum fully before use, and avoid frequent partial charges or letting the battery completely drain.
  • Store the vacuum in a cool, dry place to prevent battery degradation.

5. Replace the Battery if Needed

If your battery is old or no longer holds a charge, consider replacing it with a compatible replacement. Follow the manufacturer’s instructions or seek professional help for safe installation.
