Robot vacuum does not detect virtual walls or magnetic boundary strips.

Safety first: No internal work is required.

• 1. Verify strip placement: Place the SilverCrest magnetic boundary strip flat on the floor with no gaps, directly where you want the robot to stop.
• 2. Test on hard floor: Try the strip on a hard floor surface; very thick carpets can reduce magnetic field strength.
• 3. Correct mode: Ensure boundary features are enabled in the app and that you are not in a special mode that ignores them.
• 4. Sensor failure: If the robot crosses the strip even on hard floor, the internal magnetic sensor may be faulty and require replacement.
