Just put your feet up and enjoy your free time while the RLM 4 takes care of the lawn mowing on its own. Within the boundary wire, the robotic mower navigates randomly across the lawn without leaving any mowing stripes. By programming freely selectable entry points along the boundary wire, it reliably reaches even intricate lawn areas. The fine clippings remain on the lawn as natural fertilizer and do not need to be collected. The double-edged cutting blades ensure a razor-sharp lawn cut. The two additional clearing blades reduce debris in the housing and support the mulching function. When the battery is low, the RLM 4 automatically returns to the charging station to recharge. The RLM 4 also effortlessly handles slopes in the garden of up to 45 percent.
