Possible Causes
Dirty underside optical sensors, Sensor window scratched or damaged, Loose sensor harness, Main PCB sensor processing fault
How to Fix / Troubleshooting
Safety first: Turn off the robot and place it upside down on a soft surface.
- Clean underside sensors: Identify small downward‑facing optical sensors near the front and sides. Clean them gently with a microfiber cloth.
- Inspect for damage: Look for cracks or deep scratches on the sensor windows. If damaged, the sensor board may need replacement.
- Test on uniform floor: After cleaning, test the robot on a single floor type (e.g., all hardwood) to see if C17 reoccurs.
- Persistent C17: Indicates a likely sensor or main PCB fault that should be addressed by a technician.
