Robot mower tested

Robot lawn mowers promise to mow the lawn automatically. Almost all of them can manage a small, even area without obstacles. But as soon as it becomes uneven, beds or trees are in the way or there is even a narrow section of lawn next to it, many robotic lawn mowers fail. We show which ones make it. And which robotic mowers make it easy to adjust mowing times and mowing zones - via an app, for example.
