Abstract: An industrial floor scrubber includes a solution tank and delivery system for applying the solution to the floor, and one or more rotating brushes for removing dust and debris from the floor and respectively directing same to a squeegee and to a debris hopper. The trailing squeegee removes the remaining solution from the floor and, in combination with a vacuum system, directs the recovered solution to a cleaning solution recovery tank in the scrubbing mode of operation. In a sweeping mode of operation, the use of a dust filter is eliminated as the dust-laden air is directed past the debris hopper and onto the upraised squeegee which confines and directs the dust-laden air into a spray of fine water particles which adhere to and transport the dust-bearing water particles to the recovery tank via an applied vacuum. The heavy dust-bearing water particles drop into the recovery tank, while a demister removes the remaining water vapor with the dry air discharged to the atmosphere via a vacuum impeller.
