Kärcher RCW 4 EXTRA

Systematic navigation
Systematically cleans the entire area without forgetting anything. The direction of travel changes automatically when the mower comes into contact with obstacles. Automatically returns to the start position.

Automatic detergent application
Six pump-operated spray nozzles continuously moisten the wiping cloth.  No dripping or drifting of the spray jet. The window cleaning agent supplied ensures a streak-free shine and allows rain to run off more quickly – delaying resoiling.

Sensors for detecting frameless windows and glass surfaces
Reliable detection of window frames and other obstacles. The four corner sensors also detect the edges of frameless glass surfaces and adjust the navigation accordingly.
