How to Fix / Troubleshooting
Safety: Turn off the robot and allow it to cool for at least 30 minutes before further use.
- Clean filters and air path: Remove and clean or replace the dustbin filters. Check the suction inlet and brush housing for blockages.
- Check environment: Avoid running the robot in very hot rooms or direct sunlight. Ensure adequate ventilation around the robot and dock.
- Inspect fan and motors: Listen for unusually loud or strained motor sounds, which can indicate overload.
