Possible Causes
Main brush bearings worn, Foreign object in fan housing, Fan bearings failing, Drive wheel gears dry or damaged
How to Fix / Troubleshooting
Safety first: Turn OFF the robot and remove it from the dock.
- Isolate noise source: Run the robot briefly while holding it off the floor (carefully) to determine if the noise comes from the brush area, fan, or wheels.
- Service main brush: Remove the main brush, clean both ends, and check that the end caps and bearings spin freely. Replace the Main Roller Brush if the bearings are rough.
- Check fan: Remove the dust bin and inspect the fan inlet for foreign objects. If the noise clearly comes from the fan and persists, the Vacuum Fan Motor may need replacement.
- Inspect wheels: Rotate each drive wheel by hand. Grinding or clicking suggests internal gear wear; replace the affected Drive Wheel Module.
