Robot smells like burning plastic or hot electronics during or after cleaning.

Safety first: Immediately turn off the robot and remove it from the dock. Do not continue using it until the source is identified.

Inspect for overloads:

• Check main brush, side brushes, and wheels for jams or heavy hair buildup; clean thoroughly.
• Clean or replace filters to restore airflow.

Smell localization:

• After cooling, briefly power on the robot and try to localize the smell (fan area, brush area, battery compartment).

If the smell persists or you see smoke, discoloration, or melted plastic: Stop using the robot. A motor, battery, or main board may be failing and poses a fire risk. Have the unit inspected and repaired by a professional; replace any burnt components.
