ABSTRACT:
The present invention describes an air-floated vacuum cleaner comprising a housing having an air inlet opening, an open bottom and an inner wall, an impeller for pressurizing air within the housing to float the housing above a support surface, and a novel vacuum module/agitator located below the impeller. The vacuum module/agitator is rotatable with the impeller for agitating dust and debris on the support surface and for simultaneously suctioning the dust and debris upwards for lateral displacement against the inner wall. The dust and debris is then centrifuged to a duct communicating with the inner wall. The air-floated vacuum cleaner further includes a flotation plate module for entrapping and sealing within the housing pressurized air generated by the impeller.
