Robot vacuum emits a burning smell or very hot air from vents during or after cleaning.

Safety first: Immediately turn the robot OFF and unplug the dock. Do not continue using the robot until the cause is identified. Risk of fire exists with burning smells.

• Inspect brush bar: Remove the brush bar and check for melted plastic, burnt hair, or seized bearings. Replace the brush bar if damaged.
• Check filters and vents: Ensure all filters and vents are clean and unobstructed.
• Smell test: After cooling, smell near the motor housing. A persistent burnt electrical smell suggests motor or PCB damage.

If any components appear melted or the smell persists, do not use the robot. Have the suction motor assembly and main board inspected and replaced as needed by a professional.
