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.
