Kärcher RLM 4

500 m²

Product details

Simply put your legs up and enjoy your free time while the RLM 4 takes care of the lawn cutting on its own. Within the boundary wire, the robotic lawnmower randomly navigates the lawn without leaving any
marks on the lawn. By programming freely selectable entry points along the boundary wire, it also reliably reaches angled lawns. The fine clippings remain in the lawn as natural fertilizer and no longer needs to be collected. A razor-sharp lawncut is ensured by the two-sided ground cutting blades. The two additional spacers reduce contamination in the housing and support the mulching function. Once the battery is empty, the RLM 4 automatically returns to the charging station for charging. And also climbs in the garden up to 45 percent mastered the RLM 4 effortlessly.

Den zweiten Platz nimmt der RLM 4 von Kärcher ein. Dieser Mähroboter ist intuitiv über sein Bedienpanel zu steuern und kann in vielerlei Hinsicht individualisiert werden. Durch den PIN-Code lässt er sich auch nicht von jedem Dritten manipulieren. Das Modell ist leicht zu handhaben, bietet sehr schnell ansprechende Sensoren und schneidet das Gras auch in einer immerzu gleichmäßigen Art und Weise.
