The STIHL RMI 422.2 is a compact and intelligent robotic mower designed to automatically maintain lawns of up to 800 m² with minimal user input. Ideal for small to medium-sized gardens, it features a 60 W brushless motor, 20 cm cutting width, and fully adjustable cutting height from 20 to 60 mm. It handles slopes up to 35%, making it suitable for gently undulating ground.
This mower cuts and mulches in one go, finely chopping clippings to naturally fertilise the lawn. It automatically returns to its docking station when the battery runs low or rain is detected, then resumes mowing as scheduled. Quiet operation (approx. 60 dB) ensures it can run without disturbing you or your neighbours, even during early or late hours.
Control is intuitive via the built-in digital console, with optional app connectivity depending on your configuration. Safety is paramount, with lift and tilt sensors that stop the blades instantly if disturbed.
Whether you're at work, on holiday, or simply want more free time, the RMI 422.2 offers reliable, autonomous mowing for a perfectly tidy lawn—all season long.
