Product information and benefits

The RCW 4 window cleaning robot provides fully automatic assistance with regular cleaning of large and hard-to-reach windows and ensures a clear view. Thanks to powerful vacuum technology, it guarantees a secure hold on all smooth surfaces, including mirrors and shower cabins. Even frameless glass surfaces are cleaned quickly and reliably thanks to systematic navigation with four sensors for frame, object and edge detection. For impressive results, the microfibre wiping cloth is continuously and precisely moistened with cleaning solution by six pump-operated spray nozzles. Direct moistening prevents droplet formation and wind drift. Four automatic cleaning modes and one manual mode can be selected depending on the cleaning task and conveniently controlled via remote control. LED signals and voice output provide precise information about the machine status, for example when the detergent tank is empty. The RM 503 window cleaning agent supplied with the product reliably removes dirt, dries without leaving any residue and allows rain to run off more quickly. And even in the event of a power failure, the RCW 4 remains attached to the glass thanks to its emergency battery and safety cable.

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 re-settling of dirt.

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.

High safety standard

Safe hold thanks to reliable vacuum technology and additional safety system. Additional protection thanks to an integrated emergency battery that keeps the window cleaning robot securely attached to the window pane even in the event of a power failure.

Smart remote control for easy operation and monitoring

4 automatic modes for individual handling of every cleaning task: quick cleaning, intensive cleaning, spot cleaning and polishing. Manual control is also possible.

Intuitive user interface

ON/OFF button for simple use. Feedback and error messages via easy-to-read LED display. Always well informed: important information or the current status is announced via voice output.

Microfibre wiping cloth

The soft microfibers of the cloth optimally take in the dirt. Can be washed in the washing machine at up to 40 °C. The hook-and-loop fixing makes it extremely quick and easy to change the wiping cloth.
