  • ADAPTIVE SLOPE SPEED
    FOR UNEVEN GROUND. The Adaptive Slope Speed function ensures that your robotic lawn mower can cope well even on uneven or steep ground. To achieve this, a slope sensor constantly analyses the slope and adjusts the speed of the robotic lawn mower accordingly.
  • CONTROL CONSOLE LCD DISPLAY FOR ROBOT MOWERS
    COMFORTABLE OPERATION. The control console is integrated into the housing of the STIHL iMOW® and has a large-format LCD display. The display is also high-contrast and bright, making it easy to read even in sunlight. In RMI 6 series models, it can be removed for more convenient operation. It is easy and intuitive to make changes to settings or the recording of performance data.
  • MULCHING BLADES FOR ROBOTIC MOWERS
    AUTOMATIC LAWN FERTILISATION. The mulching blade lets you cut grass and fertilise it at the same time. It cuts the grass in stages and shreds the clippings into fine particles that deliver nutrients and moisture to your lawn. The specially shaped blades automatically change rotation direction each time the blade stops, ensuring even wear. Blades can be changed easily and without tools.
  • DYNAMIC MOWING PLAN
    OPTIMISED WORKING TIME FOR YOUR MOWER. With the dynamic mowing plan, you define a time frame within which the automatic mower can be operational each day. Your iMOW® robotic lawnmower will then automatically determine when to mow the lawn during this period for optimum results. Even if the mowing process is interrupted due to rain, for example, it will automatically catch up on the task later within the time frame.
  • iMOW® ROBOTIC MOWER DRIVE
    HIGH PERFORMANCE EVEN ON SLOPING GROUND. iMOW® robotic mowers mow with consistently high quality, including on hilly terrain. Depending on the series, they can cope with even steep inclines.
