How to Fix / Troubleshooting

Safety first: Immediately turn OFF the robot and unplug the dock. Do not continue using the robot until the cause is identified.

  • Allow to cool: Let the robot cool for at least 30 minutes.
  • Check for clogs: Empty the dustbin, clean the filter, and inspect all air passages and the main brush area for blockages.
  • Smell localization: With the bottom cover removed (if you are comfortable), carefully smell near the suction motor and brush motor to identify the source.
  • Component replacement: If the smell is strongest at the fan motor or if there is visible discoloration, replace the suction fan motor assembly. If near the brush motor, replace the main brush motor assembly.
  • If unsure: Stop using the robot and have it inspected by a professional to avoid fire risk.
