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.
  • Test after cooling: Once cooled and cleaned, run a short cleaning cycle and monitor temperature via the app if supported.
  • Component replacement: If overheating recurs quickly, the suction fan motor or main control board temperature sensor may be faulty and require replacement.
