WINBOT W730 Window Cleaning Robot automatically scans and calculates the size of your window, then programs a custom cleaning path for maximum efficiency. But WINBOT W730 also has a Remote Control for your convenience. The Winbot W730 is equipped with a frameless window detection system so you can clean glass doors, railings and shower stalls with ease. Also, it is easy to use. Switch the robot ON, place it on the window, and press start. You can sit back, relax and let winbot do the work. WINBOT W730 is equipped with dual suction rings. If the outer ring senses any loss of suction, a signal will be sent to Winbot’s brain to reverse direction and select a new path.
