How to Fix / Troubleshooting
Safety first: Turn off the robot before freeing it from tight spaces.
- Free the robot: Gently lift the robot away from the obstacle. Avoid yanking if something is caught underneath.
- Inspect underside: Check for objects stuck under the robot (toys, cables, rug tassels). Remove any foreign objects.
- Check for damage: Look for cracked plastic, bent bumpers, or misaligned wheels that might indicate impact damage.
- Use virtual walls or no-go zones: In the Wyze app, set up virtual boundaries to keep the robot away from problem areas.
- If C18 appears even on open floor: The chassis or internal frame may be misaligned, or sensors may be misreading. This requires internal inspection and possible frame or sensor bracket adjustment by a technician.
