How to Fix / Troubleshooting
Safety first: Turn off and unplug the robot from the dock.
- Isolate noise source: Run the robot briefly and listen to determine if the noise comes from the brush area, wheels, or fan (suction).
- Clean moving parts: Remove the main brush and side brush, clean hair from end caps and axles, and test again.
- Check fan noise: If noise is present even with brushes removed, the Suction Fan Motor may have debris or worn bearings. Cleaning requires opening the unit; if uncomfortable, seek service.
- Inspect wheels: Spin drive wheels by hand; grinding or clicking suggests gearbox wear, requiring Drive Wheel Motor Assembly replacement.
