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

Safety first: Bring the mower under cover and turn it OFF.

• Check settings: In the mower menu or app, ensure the rain sensor feature is enabled.
• Clean sensor: Wipe the rain sensor area on the top cover with a damp cloth and dry.
• Test with water: Lightly sprinkle water on the sensor area and see if the mower responds (when safe to test).

If the mower never reacts to rain, the sensor or its wiring may need replacement.
