The RCX 4 robotic lawn mower mows lawn areas of up to 1500 square meters wirelessly and fully automatically. GPS, RTK antenna, and AI camera enable navigation without boundary wires. The precise positioning allows for mowing in parallel lines, completing the task in no time. Obstacles such as trees or hedgehogs are intelligently detected and navigated around with optimal distance. The cutting height can be adjusted variably between 2 and 6 centimeters. Through app remote control or AI surface detection, the lawn mower maps the working areas. Work zones and no-go zones can be set up. Individual settings for schedule, driving behavior, and much more can be easily adjusted via the app. The all-wheel drive allows for slopes of up to 60 percent and a particularly gentle turn to protect the lawn. All basic settings can be read and changed on the LCD display.

With the RCX4, Kärcher has a robot mower in its range that is technically state-of-the-art. Thanks to its all-wheel drive, it is also suitable for gardens with slopes. Until now, the range of machines available for such gardens has been rather limited. In addition to the key technical data, the machine also impresses with its well-designed installation routine.
