Randommization

Winbot by Ecovacs Robotics is quite similar to its cousin, the Roomba in size and work. It does however, differentiate itself in a different field than that of its cousin, for Winbot finds more pleasure in sticking to window panes and moving around them unsupervised to leave them sparkling clean.

Winbot has two robots, one for movement and the other to power its concentric suction rings that help it stick to the glass being cleaned. Should these suction rings fail, the robot lights up its sensors and makes efforts to prevent from falling down.
