How to Fix / Troubleshooting
Safety: Unplug the auto-empty dock from the wall before servicing.
- Check dust bag: Open the dock cover and verify that the dust bag is installed correctly and not overfilled. Replace if full.
- Inspect suction channel: Look into the dock's suction port and the robot's rear port for blockages. Remove any debris.
- Clean dock filter: If your dock has an internal filter, remove and clean or replace it according to the manual.
- Reconnect power and test: Plug the dock back in and command a dustbin empty cycle from the app or robot.
- Listen for dock motor: If the dock motor does not start or makes abnormal noise, the dock suction motor or dock control board may be faulty.
- Replacement: Replace the auto-empty dock assembly or its internal suction motor module as needed.
