STIHL RMI 422.2 P Robotic Mower – Interactive Smart Mowing for Up to 1,500 m²


The STIHL RMI 422.2 P is the P‑version of the popular 422.2 model, with enhanced terrain handling, longer runtime, and interactive programming, making it ideal for medium to large gardens. Built on a compact yet rugged platform with a 60 W brushless motor, it cuts 20 cm wide and adjusts height between 20–60 mm, easily handling slopes up to 35‑40%. Engineered for performance and quiet operation, it's your reliable, hands-free solution to lawn care.


With built-in rain, lift, and tilt sensors, it senses weather conditions or interruptions and returns to its dock when needed. The integrated PIN-protected security and interactive display allow easy programming right on the unit, and some retail configurations support optional smartphone app control. The smart speed management system also extends coverage and runtime—often handling lawns up to 1,500 m² across multiple cycles, despite its compact form.
