Possible Causes
Main brush jammed, Suction motor overloaded by a clog, Failing fan motor bearings, Electrical short on the PCB
How to Fix / Troubleshooting
Safety first: Immediately turn OFF the robot, remove it from the charging dock, and disconnect its power. Do not continue using it until it has been inspected.
- Inspect for jams: Check the main brush, side brush, and wheels for obstructions, and remove any debris.
- Check air path: Ensure filters and ducts are not clogged, which can overheat the fan motor.
- Smell source: Carefully smell near the brush area and the exhaust. If the odor is strongest near the exhaust, the suction fan motor may be failing.
- Do not ignore: If the smell persists or you see smoke, stop using the robot and contact Ultenic support. Internal components such as the main board or fan motor likely need replacement.
