How to Fix / Troubleshooting

Safety first: Immediately power off the robot and remove it from the dock. Do not continue using it until inspected.

Step-by-step:

  • Check for jams: Inspect and clean the main brush, side brush, and wheels for obstructions.
  • Smell test: With the bottom cover off (if you are comfortable), carefully smell near the fan and brush motor areas to localize the odor source.
  • Allow to cool: Let the robot cool for at least 30 minutes, then run a short test. If the smell returns quickly, stop use.

Persistent burning smell indicates a failing motor or electrical component. Do not continue operating; arrange for professional diagnosis and replacement of the affected motor or board.
