Compact, capable and communicative. The STIHL RMI 422 PC iMOW® robotic mower combines a number of features to make it the ultimate convenience mower. Equipped with the iMOW® app, you can conveniently configure a host of settings on this PC version using an app on your smartphone or tablet. For example, you can change the mowing plan, read status messages and pause or start new mowing operations from the comfort of your home or office. Within the tailored active times, the smart robotic mower automatically picks the optimum mowing windows for the best possible cut using the rain sensor and a comparison with online weather services. The RMI 422 PC has a long life Lithium-Ion battery, which makes the iMOW® robotic mower perfect for medium-sized lawns up to 1,700 m².
Not only does the robotic mower cut your lawn automatically, it also supplies it with nutrients at the same time. The iMOW® robotic mower cuts and shreds the grass in one step, returning the clippings to the soil, where it acts as a biological fertiliser for a lush, healthy lawn. If the garden is steep or uneven, the adaptive slope speed function adapts the speed on a gradient up to a 40% incline. If the iMOW® robotic mower encounters any obstacles when mowing, sensors in the movable hood detect the impact and the machine sets off in a different direction.
