A Sweeper is a vehicle created by Madame Gasket and her son, Phineas T. Rachet. The sweeper is designed to capture outmodes and take them to the underground Chop Shop. The sweepers are an imposing figure, with grey markings and mouth-like appendages that open and swallow careless non-upgraded robots that walk along the lower levels of Robot City. Later, Rachet creates a new type of sweeper, the Super Sweeper, which has more featuers and only one eye, making it less vulnerable to destroy.
