Possible Causes
Blocked air vents causing overheating, Suction motor drawing excessive current, Battery temperature sensor fault, Main board thermal sensor failure
How to Fix / Troubleshooting
Safety first: Turn OFF the robot and let it cool for at least 30 minutes away from heat sources.
- Step 1 – Check ventilation: Inspect all air inlets and outlets on the robot body. Remove dust buildup with a soft brush.
- Step 2 – Clean filters and bin: A clogged filter can cause the motor to overheat. Empty the dust bin and clean or replace filters as per the manual.
- Step 3 – Avoid thick rugs initially: Test the robot on hard floors to reduce load on the motor.
- Step 4 – Monitor runtime: If the robot overheats quickly even after cleaning, the suction motor or temperature sensor may be failing and should be replaced.
