Stihl RMI 422 iMOW®

The compact RMI 422 robot mower will mow small to medium sized lawns of up to approx. 800 m² and is designed to do this in the shortest time possible, allowing you full access to your garden when you want it. As it is fully automated, once iMOW® is installed, it will mow, charge and adapt its schedule all by itself. If the robot mower battery runs low or it starts to rain, the RMI 422 will return itself to the docking station, and depending on how much of the lawn still needs to be cut, it will decide whether to charge itself quickly or slowly helping to conserve power. *Please Note: If you require professional installation of this product, please contact us either through email or phone. This will incur an extra cost dependent on lawn complexity.
