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. The RMI 422 PC comes with a 5 year extended domestic warranty (subject to registration and annual servicing).

1 App control

The iMOW® app transforms a STIHL iMOW® robotic mower into a standalone smart garden system. The intuitive app menu can be accessed via smartphone or tablet, which means that many mowing settings can be made not only directly on the machine but also while on the move. The free iMOW® app offers a real-time overview of main functions and performance data. Using the interactive mowing plan, time windows can be defined for each day during which the iMOW® robotic mower works flexibly and independently and charges its battery. Thanks to the integrated rain sensor and receipt of online weather forecasts, the automatic lawn mower only mows in suitable weather conditions. Using GPS localisation, the current location can also be viewed and a desired zone can be defined as the preferred mowing location at a specific time.

2 Mulching mowing deck

The sturdy iMOW® mulching blade ensures a precise cutting pattern even on higher grass growth. Its rotational direction changes automatically every time the blade stops. This means that the blades of the automatic lawn mower wear evenly. The blade can be changed without the need for tools.  

3 Adaptive slope speed

Using the adaptive slope speed function, the STIHL iMOW® robotic mower adapts its speed on uneven terrain. The integrated tilt sensor constantly analyses the position of the automatic lawn mower and adapts its speed accordingly.
