Possible Causes

How to Fix / Troubleshooting
Safety first: Turn OFF the robot and flip it over on a soft surface.
- Check side brush attachment: Ensure the side brush is firmly pressed onto its shaft and any retaining screw is tight.
- Inspect for damage: Look for cracks in the side brush hub or shaft.
- Manual spin test: Try to spin the side brush by hand. If it spins freely without resistance, the gearbox may be stripped. If it is seized, debris or internal damage is likely.
- Test in operation: Turn the robot ON and start cleaning while observing the side brush. If it never moves, the motor or driver is likely faulty.
- Replace module: Replace the side brush motor module if accessible, or have a technician perform the replacement.
