Stihl iMow 632P Review
Professional Class for Large Gardens
The Stihl iMow 632P (model designation: RMI 632 P) is the professional robot mower in the Stihl portfolio, designed for owners of large gardens up to 3200 m². With a slope capacity of 50%, it also handles challenging, hilly properties. The build quality meets the high Stihl standard: robust plastic parts, premium electronics, and a powerful brushless motor.
The orange-grey design is typical Stihl and makes the mower a real eye-catcher in the garden. The 4-button control on the housing allows quick setup even without the app. The clear LCD display shows all important information at a glance.
Mowing Performance & Floating Disc
The 3-blade disc system with floating technology is the heart of the iMow 632P. The spring-mounted cutter disc adapts to ground irregularities and ensures a clean, even cut – even on uneven terrain. With 230 mm cutting width and a cutting height of 20 to 60 mm, the mower is suitable for different grass types and usage requirements. The mulching system finely shreds clippings and distributes them evenly as natural fertilizer.
The mowing time per charge is approximately 200 minutes – one of the best values in this class. After just 50 minutes, the battery is fully charged again and the mower can continue working. This excellent ratio of mowing time to charging time is a decisive advantage of the Stihl iMow 632P.
Navigation & GPS
The iMow 632P uses a combination of boundary wire and GPS support for navigation. The mower follows an optimized random pattern supported by GPS position data. The Stihl smart app shows the mower's current location on a map and provides operating data such as mowing duration, charge cycles, and error messages. The adaptive slope speed function automatically adjusts speed to the incline for a uniform cut even on slopes.
App & Smart Features
The Stihl smart app is the mower's command center. Mowing times are set, operating status is checked, and settings are configured here. The app is clearly laid out and offers intuitive navigation. The mower features a reliable rain sensor, anti-theft protection, and automatic return to the charging station when the battery is low. Installation requires laying a boundary wire – the included installation kit makes the job easier.
Verdict
The Stihl iMow 632P is an excellent choice for demanding garden owners with large properties. The combination of robust Stihl quality, short charging time, and high cutting performance makes it one of the best robot mowers in the premium class. The high price and the need for a boundary wire are the biggest drawbacks – but those willing to accept these will get a reliable and long-lasting robot mower.
