The compact Stihl RMI 422 P iMow robotic lawn mower is perfectly suited for small to medium sized lawns. As it is fully automated, once the iMow is installed it will mow, charge and adapt its schedule all by itself. Thanks to an efficient mulching blade the lawn will look lush and green without ever having to dispose of the grass clippings. Equipped with a powerful battery, the RMI 422 P can handle lawns up to 1500m², gradients up to 40% and is designed to do all this in the shortest time possible, allowing you full access to your garden when you want it. The RMI 422 P comes with a 5 year extended domestic warranty (subject to registration and annual servicing).

The Stihl iMow robotic mowers comply with all applicable safety standards. However, the iMow robotic mower is not a toy. During the iMow robotic mower's active times, in particular children, bystanders and animals must be kept out of the working area. Please refer to the operating instructions for further information.
