Stihl iMow Robotic Lawnmower

Time is precious , especially your leisure time. Enjoy more time surrounded by the beautiful things in life while your lawn is taken care of by iMow, the robotic lawnmower from Stihl.

The iMow robotic mower doesn’t just mow the lawn, it also provides fully automatic lawn care tailored to your garden. Extremely fast, easy to use and a lush green lawn.

The compact 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 1,000 m², gradients up to 40 percent and is designed to do all this in the shortest time possible, allowing you full access to your garden when you want it.





Green Energy

iMow is powered by Lithium-Ion battery technology so there are no emissions or fumes to worry about. The adpative charging system alligns the charge time with the cutting schedule choosing a slow and gentle charge more often to help save energy.




Green Garden

The great thing about the Stihl iMow robotic mower is that it mows and cares for your lawn at the same time. During mowing, it shreds the grass clippings finely, which fall back onto the lawn acting as a effective fertiliser (known as mulching). Not only does this provide vital nourishment to help grow a thick and healthy lawn, it also means there are no grass clippings to collect and dispose of.






Green Light

Come rain or shine iMow keeps mowing until the job is done. Adaptive slope speed technology means iMow can mow inclines of up to 45% with ease. The robotic mower adjusts its speed to suit the mowing conditions, moving slower over long, thick grass or on hilly terrain.


iMow finds its own way.

Stihl iMow mows your lawn automatically and according to your needs. The built in sensors safely react to moving and static objects within the garden, simply moving iMow off into another direction.

iMow will also remember how much lawn has been cut and how much is left of the program. If it has a large area left to mow and the battery is running low it charges it faster. And when it is done working for the day it charges slower and more economically, which helps to prolong battery life and save energy.


Quick and smart.

iMow is among the fastest robotic mowers on the market, allowing you more time to enjoy your freshly cut lawn. But it’s not enough to just cut quickly, the result must be top quality too. Therefore iMow adjusts it’s working speed according to the gradient of the lawn, the grass length and humidity for a precise finish.

Innovative cutting technology.

iMow uses a double sharpened blade to mow the grass. The blade rotation changes directions every time it stops, resulting in even wear and a longer service life. The central blade has a safety zone between the cover and blade – additionally the blade stops automatically as soon as someone tries to lift iMow, or if it topples over.
During mowing iMow cuts and finely shreds the grass clippings which fall back onto the lawn acting as an effective, natural fertiliser (known as mulching).

iMow keeps on mowing.

iMow is an extremely reliable robotic lawnmower, able to cut the most demanding of lawns. Several of the models are capable of mowing gradients of up to 45% without any problems.

The rain sensitivity level can be easily adjusted so iMow can carry on its schedule whatever the weather. The clearing plate on the underside of the mower reduces grass build up, ensuring optimum cutting performance at all times. This plate also helps to reduce noise during operation.

Connective technology.

Now you can conveniently connect to your RMI 632 PC iMow using an app on your smartphone or tablet. The simple to use app allows you to configure the mowing plan, read status messages and pause or start new mowing operations from the comfort of your home or office. You can also easily check maintenance information such as if the blade needs to be replaced, and much more. The Stihl iMow app is available for download from Google Play, App Store and Windows Store.
