Robot vacuum smells burnt or produces a strong odor during operation.

Safety first: Immediately turn OFF the robot, remove it from the dock, and disconnect power. Do not continue using it until inspected.

• Inspect for jams: Check 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 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.
