In the Lymow One Plus test, I show how this robotic lawnmower performs in practice without a boundary wire on a large and demanding area. With RTK navigation, chain drive, 45° incline and a cutting width of 40 cm, the Lymow takes a significantly different approach to classic robotic mowers. I tested the new Lymow One Plus extensively and compared it directly with the Lymow One. The focus is on performance, navigation, off-road capability and the question of whether this system is really worthwhile for large plots of land. The article provides a detailed insight into the technology, set-up, practical test and my experiences – including strengths, weaknesses and a…
