Stihl RMI 632
Product description

The robotic lawn mower Stihl RMI 632 is suitable for an area of approximately 3000 m2 according to the manufacturer’s recommendations. The area size takes into account the mower’s design parameters. The working area is defined by the boundary wire. The mowing method and the mowing movement is random. Continuous information about already mown area is not available. Robotic lawn mower returns to the charging station along the wire. The cutting width is 28 cm. The range for cutting height adjustment is from 20 mm to 60 mm. The robotic lawn mower Stihl RMI 632 can mow the area of the maximum slope of 24 degrees or 45 percent. The motor of Stihl RMI 632 is designed brushless. The battery capacity is 4.5 Ah, which represents the overall energy of 130 Wh by the system voltage 29 V. The charging time is approximately 60 minutes. The robotic lawn mower with the full charged battery can mow for 90 minutes. The mower weight with the battery included is 14 kg.

For easy detection of the slope degree, we recommend using a digital spirit-level when selecting a robotic lawn mower. It allows you to measure the slope in degrees. To make sure that you correctly identify the maximum slope value on your lawn, it is necessary to measure it at multiple locations and take into account the highest value measured.
