How to Fix / Troubleshooting
Safety first: Power off the robot before inspecting sensors.
- Inspect for impact damage: Check the robot's body, especially around the bumper and top turret, for signs of drops or collisions.
- Clean all sensors: Wipe cliff sensors, bumper IR windows, LiDAR or camera windows, and side wall sensors with a microfiber cloth.
- Reset robot: Perform a factory reset via the Wyze app or button sequence (consult manual). Note that this may erase maps and settings.
- Rebuild map: After reset, create a new map in a clear environment to allow sensors to recalibrate.
- If C20 remains: Physical misalignment or internal sensor failure is likely. Correcting this requires opening the robot and adjusting or replacing sensor modules, which should be done by a technician.
