Clean or Replace Filters

  • Remove the pre-filters and clean them thoroughly with water. Allow them to dry completely before reinstalling.
  • Replace filters if they are excessively dirty or damaged to prevent airflow restrictions that strain the battery.

Optimize Charging Practices

  • Always use the original Dyson charger and avoid using third-party chargers.
  • Charge the vacuum fully before use and avoid partial charges or letting the battery fully discharge frequently.

Perform a Battery Reset

  1. Turn off the vacuum and disconnect it from the charger.
  2. Remove the battery if possible (consult your model’s manual).
  3. Wait for 15 minutes, then reattach the battery securely.
  4. Reconnect the vacuum to power and see if the runtime improves.

Replace the Battery if Necessary

If your battery is old or no longer holds a charge after troubleshooting, consider replacing it with a compatible replacement. Check with Dyson or authorized parts suppliers for genuine batteries designed for your model.
