Product information and benefits

The RCW 2 window cleaning robot provides fully automatic assistance with regular window cleaning and automatically ensures a clear view. Thanks to powerful vacuum technology, the RCW 2 guarantees a secure hold on all smooth surfaces, ideal for large and hard-to-reach windows and mirrors. Systematic navigation and two sensors for frame and object detection ensure fast and reliable maintenance cleaning. The two rotating discs with microfibre mop covers simulate a manual wiping motion, ensuring impressive results. Two ultrasonic spray nozzles produce a fine spray mist of detergent, which is sprayed precisely onto the window pane without dripping. Four automatic modes and one manual mode can be selected depending on the cleaning task and conveniently controlled via remote control. In addition, LED signals and voice output provide status messages about the machine at any time. The RM 503 window cleaning agent supplied with the machine reliably removes dirt, dries without leaving streaks, and allows rain to roll off more quickly for a visibly fresh look. And even in the event of a power failure, the RCW 2 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

Two ultrasonic spray nozzles ensure drip-free moistening of the window pane. The window cleaning agent supplied ensures a streak-free shine and allows rain to run off more quickly – delaying re-settling of dirt.

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.

Two sensors for frame and object detection

Reliable detection of window frames and other obstacles.

Wiping cloths made from high-quality microfibres

The soft microfibers of the cloth optimally take in the dirt. Can be washed in the washing machine at up to 40 °C.
