The Shiny prototype followed, featuring the same bladder system and cylindrical cleaning head first tested on Squeaky. One of the unique features of this prototype was the Omni wheels, which allowed the robot to move in any direction and get extremely close to walls and corners. Another unique feature of the robot was its small form factor, despite supporting a 105 L water carrying capacity. The 105L tank and the lithium ion batteries allowed Shiny to clean uninterrupted for up to 3 hours.
