2. Check and Clean the Filters

  • Remove the pre-filters and main filters from the vacuum according to the user manual.
  • Rinse the filters thoroughly with water and let them air dry completely, ideally 24 hours.
  • Reinstall the dry filters and run the vacuum to see if battery performance improves.

3. Inspect the Battery and Connections

Check the battery for any visible damage or corrosion. If accessible, disconnect and reconnect the battery terminals securely. Consider replacing the battery if it is old or shows signs of failure, as batteries can lose capacity over time.

4. Update Firmware and Reset Vacuum

Use the Dyson app or follow the manufacturer’s instructions to check for available firmware updates. Updating can fix bugs affecting battery life. To reset, turn off the vacuum, remove the battery (if removable), wait a few minutes, then reassemble and test.

5. Replace Worn Components

If you’ve tried all steps but the battery still drains quickly, consider replacing the filters with a 3Pack Pre Filters Replacement or similar, or the battery itself if it’s degraded. Always use genuine parts to ensure compatibility and safety.
