Myth #3: Rain is the end of the world
A real GARDENA Robotic Lawnmower does not stop for rain. In fact, unlike many other devices, it will happily keep mowing even when it is dirty with clumps of grass and damp earth. And it will remain totally efficient and reliable. That is also why it doesn't need a rain sensor.
To clean it, simply spray it with the garden hose! Only GARDENA offers this feature in this device class.
