Perfect for small lawns, around pools and even sloping terrain, the fast manoeuvrable RMI 422 iMOW® Robotic Lawnmower will cover every corner of your lawn without you lifting a finger. The RMI 422 can handle lawns of up to 1500m² and is fully automatic so it will mow, and charge at it's own schedule. If the Battery runs low or it starts to rain the iMOW® will return to the docking station. You will not even need to rake the grass clippings because the Lawnmower has a mulching blade that finely shreds the grass, putting vital nutrients back into the lawn.

There are 15 different cutting heights from 20 - 60mm to suit your preference and lawn type.

The price displayed does not include the cost of installation. At STIHL SHOP, we have trained experts that will perfectly install your MOW® to suit your garden.

    The Docking Station comes with the unit, it is the mowers home and where it goes to charge. When mowing the iMOW® is guided by the signal from the perimeter wire, this signal is passed via the docking station. If it rains or the battery runs low the robotic mower returns to the station. The iMOW® has an intelligent charging system, it decides if an express charge is required so it can continue mowing or if the battery can be charged more gently to conserve electricity.
