Abstract
An improved, low cost floor cleaning device usable for cleaning carpets, upholstered furniture, walls, autos or hard surface flooring is provided which includes cooperating structure for easy pad installation and removal, and for positive pad connection to the device during use. The floor cleaner includes a high torque gear motor operatively coupled to a circular, rotatable disk having a series of peripheral depending teeth. The disk teeth are adapted to fit into and engage structure-defining interstices or zones associated with a floor-engaging pad, so that a positive mechanical interlock is provided. In addition, an upstanding, inwardly biased collar is secured to the pad for engaging or entrapping the disk and thus ensuring a secure connection between the disk and pad. In preferred forms, the device includes an elongated handle having handholds both at the uppermost end of the handle and intermediate the ends thereof; in this fashion the user can exert considerable downwardly directed force against the pad to facilitate floor cleaning.
