Robot vacuum emits a burning smell or very hot air from the exhaust during cleaning.

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

• Step 1 – Check for blockages: Remove the dustbin, filter, and main brush. Inspect and clear all suction paths.
• Step 2 – Clean filter: Replace a heavily clogged filter; restricted airflow can overheat the motor.
• Step 3 – Inspect motor area: Open the robot and visually inspect the suction motor for burnt marks or melted plastic. Smell near the motor to confirm the source.
• Step 4 – Replace motor: If the motor shows signs of overheating or still smells burnt after cleaning, replace the Medion suction motor assembly.
• Step 5 – Professional service: If you see burnt wiring or PCB damage, have the mainboard and wiring harness inspected and repaired by a qualified technician.
