      Function and operation

      The device consists of the cleaning robot and the remote control.

      The remote control is used to control the device manually, select the cleaning mode and switch the voice output on or off.

      The cleaning robot adheres to the glass surface to be cleaned via a self-generated vacuum and moves it down automatically.

      2 ultrasonic spray nozzles atomise the cleaning solution into a mist and distribute it evenly over the glass surface.

      Cleaning is carried out by 2 cleaning discs equipped with microfibre wipe covers. A wiping movement is generated by rotating the cleaning discs.

      The device has various cleaning modes, see Cleaning modes.

      In automatic mode, the cleaning robot travels along the glass surface in overlapping paths and stops automatically when cleaning is complete.

      The cleaning navigation system ensures that the glass surface is evenly travelled over and cleaned thanks to systematic route planning.

      The position memory function ensures that the device automatically returns to the starting point for easy removal from the glass surface after cleaning.

      In manual cleaning mode, the cleaning robot is controlled using the arrow buttons.

      For operation, KÄRCHER microfibre wipe covers and KÄRCHER window cleaning solution RM 503 are required.

      Cleaning modes

      The device has various cleaning modes.

      Quick cleaning (automatic mode):

      Single pass over the glass surface in horizontal movements.

      Intensive cleaning (automatic mode):

      The glass surface is passed over twice in horizontal movements, followed by edge cleaning and polishing.

      Spot cleaning (automatic mode):

      Back and forth movements on a small surface.

      Polishing (automatic mode):

      Single pass over the glass surface in horizontal movements without spraying detergents.

      Manual cleaning:
