Robot mower does not detect rain and continues mowing in wet conditions despite having a rain sensor.

Safety first: Turn off the mower before cleaning or adjusting the rain sensor.

• Check settings: In the mower menu or app, ensure the rain sensor function is enabled and configured correctly.
• Clean sensor: Locate the rain sensor (often on the top housing or near the station) and clean it with a soft cloth to remove dirt and grass.
• Test with water: Lightly sprinkle water on the sensor and observe if the mower responds by returning to base or pausing mowing.
• Inspect wiring: Check the cable from the sensor to the main PCB for damage or loose connections.
• Replace sensor: If there is no response despite correct settings and wiring, replace the rain sensor module.
