The window cleaning robot RCW 4 replaces manual cleaning of large and hard-to-reach windows and ensures a clear view. 
Thanks to powerful vacuum technology, it guarantees a firm hold on all smooth surfaces, including mirrors and shower cubicles. Even frameless glass surfaces are cleaned quickly and reliably thanks to systematic navigation and four sensors that detect frames, objects and edges. 
For the best results, the microfiber cloth is constantly and precisely moistened with cleaning solution by means of a spray nozzle operated by six pumps. 
Direct humidification prevents the formation of drops and dispersal by the wind. 
Depending on the degree of soiling, you can choose between four automatic and one manual mode, which is convenient to control with a remote control. 
LED signals and voice output provide accurate information about the device's status, such as when the detergent tank is empty. 
The included window cleaner RM 503 reliably removes dirt, dries streak-free and allows rain to run off faster, ensuring long-lasting cleanliness. 
Even in the event of a power outage, the RCW 4 stays attached to the glass thanks to the battery reserve and safety rope.

Systematic navigation

The direction of movement changes automatically when the robot encounters obstacles.
Automatically returns to the starting position.

Automatic detergent application
Six pump-operated spray nozzles constantly moisten the cleaning cloth. 
The spray jet does not drip or deviate with the wind. 
The included window cleaner ensures streak-free cleaning and allows rain to run off faster, delaying the formation of new dirt.

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

High safety standard
