Unique, extra Safety Tether system
A suction cup and cored-based device called a Safety Tether System ensures that WINBOT will stay safe during outdoor as well as indoor cleaning. With a 2.4 GHz connection to the main robot, the system monitors and ensures safe status of the robot. The robot will emit alarms if the suction cup in system air pressure is smaller than 3.5Kpa to ensure the tether's connection to the glass. If the robot appears to risk falling, the tether will draw it back towards itself, providing an active system of protection.
