Safety first: Immediately turn the robot OFF and unplug the charger. Do not continue using the robot until the cause is identified.
- 1. Visual inspection: Check for melted plastic, discoloration, or burn marks around the vents, brush area, and wheels.
- 2. Clear blockages: Ensure all air vents and the suction path are free of dust and debris.
- 3. Check brushes: Remove main and side brushes and inspect for jams that could overload motors.
