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.
Fitted with a robust mulching blade, your grass will be finely shredded returning vital nutrients back into the soil. This also eliminates the need to dispose of any grass clippings. The iMOW® RMI 422 boasts 15 different cutting height settings, varying from 20mm-60mm so you can adjust it to suit you and your lawn!
