To help keep those edges and borders in tip-top shape STIHL are offering a free FSA 45 Lithium-Ion grass trimmer with any STIHL iMow purchased from your local specialist iMow dealer.

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).

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, children, bystanders and animals must be kept out of the working area. Please refer to the operating instructions for further information.

Features

RMI 422 PC

Standard features

  • Bright LCD display Zoom
    Bright LCD display

    The control panel is integrated into the housing of the STIHL iMow robotic mower and features a large LCD display. It provides a intuitive way of recording all settings, as well as a way of viewing all functions and performance data of the automatic lawn mower. The high-contrast, bright display is easy to read even in sunlight.

  • Movable hood Zoom
    Movable hood

    The movable hood with sensors protects the STIHL iMow robotic mower from weather and obstacles. If the iMow robotic mower comes up against an obstacle during automatic mowing, the integrated sensors detect contact with the object and changes direction.

  • All-round protection Zoom
    All-round protection

    The STIHL iMow robotic mower is equipped with various sensors. As soon as someone attempts to pick it up while mowing, it stops. In addition, the automatic lawn mower can be protected with a PIN code. If it is configured so that it can only be operated by entering a PIN, it is protected from unauthorised use. On all C models, the iMow robotic mower can also be located using the free iMow app via smartphone or tablet using GPS.

  • Standard equipment Zoom
    Standard equipment

    Standard equipment for the STIHL iMow robotic mower includes the machine, the docking station, four pegs for securing the docking station to the ground as well as an iMow ruler as an aid for laying the perimeter wire. An installation kit is also required to install the iMow robotic mower.

  • Docking station Zoom
    Docking station

    The docking station is included as standard equipment for the STIHL iMow robotic mower. It is both the robotic mower's home and where it charges its battery. At the same time, it is the starting point for every mowing operation. When driving, the automatic lawn mower is guided by the signal transmitted by the perimeter wire at the edge of the lawn. This signal is fed via the docking station. If it rains or the battery runs down during mowing, the iMow robotic mower independently returns to the docking station and recharges its battery. Thanks to its intelligent charging system, the iMow decides independently whether an express charge is necessary due to another imminent mowing operation or whether the battery should be charged more gently in normal mode. The docking station can be placed within or outside the lawn area.

  • Mulching mowing deck Zoom
    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.

  • Offset drive home Zoom
    Offset drive home

    By default, the iMow robotic mower travels back home to the docking station along the perimeter wire. If required, and depending on the condition of the edge of the mowing area, the iMow can also travel to its docking station with an alternating offset to the perimeter wire.

  • Control panel Zoom
    Control panel

    The control panel with integrated and bright display is used on all STIHL iMow robotic mowers for easy setup and fast display of machine information. The high-contrast display means the control panel can also be used in sunlight. The panel is flush-mounted in the housing of the automatic lawn mower.

  • iMow robotic mower drive Zoom
    iMow robotic mower drive

    The STIHL iMow robotic mowers feature a drive that enables them to mow hilly terrain with consistently high quality. The RMI 422 can handle gradients of up to 35%, while the other automatic lawn mowers from the RMI 4 series can cope with a gradient of up to 40%.

  • App control Zoom
    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.

  • Adaptive slope speed Zoom
    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.

  • Dynamic mowing plan Zoom
    Dynamic mowing plan

    Using the interactive mowing plan of the STIHL iMow robotic mower, individual time windows during which the machine can be in operation can be defined for each day. Within these active times, the automatic lawn mower automatically determines the best times to mow for an optimum result. If it has to interrupt mowing because of rain, it automatically catches up later within the specified time window. The dynamic mowing plan can be called up and activated via the control panel or conveniently via the iMow app.

  • Wheels with traction pattern Zoom
    Wheels with traction pattern

    The smooth-running wheels with traction pattern ensure that the STIHL iMow robotic mower moves with precision. Especially on hilly lawns with a gradient of up to 40% and dense grass growth. The treaded wheels of the automatic lawn mower are self-cleaning.
