Floor scrubber dry sweep apparatus
First Claim
1. A combination floor sweeper and scrubber apparatus comprising:
- plural rotating scrub brushes for engaging and cleaning the floor, including removing debris from the floor and displacing dust on the floor in a rearward direction relative to the direction of travel of the apparatus during operation;
a solution storage tank and delivery system for applying a cleaning solution to the floor;
a solution recovery tank;
a debris hopper disposed aft of said rotating scrub brushes and adapted to receive and store debris removed from the floor;
a squeegee disposed aft of said debris hopper, and in spaced relation to the floor;
an air displacement arrangement for drawing dust-laden air from said rotating scrub brushes past said debris tank and into engagement with said squeegee, said air displacement arrangement including a first elongated vacuum hose coupling said squeegee to said solution recovery tank; and
a second elongated delivery hose coupling said solution storage tank to said first elongated vacuum hose for delivering fine water particles to the dust-laden air in said first elongated vacuum hose, wherein said fine water particles adhere to the dust particles for deposit in said solution recovery tank.

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.
