Abstract
A cleaning and restoration system 10 for floors 11 and other hard surfaces is disclosed. The system 10 has an cleaning head 12 which can be moved across a floor 11 or other hard surface. The cleaning head 12 impinges particulate media upon the floor 11 to remove soils and provide a slip-resistant surface. The media is entrained into the air by a pressure tank 18. The media is reclaimed in a classifier 17; and the dust, soils, and other undesirable materials are filtered in a dust collector 57. A compressor 20 and a vacuum blower 22, and other components of the system are mounted on a truck 19. A method for utilizing the restoration system 10 is also disclosed.
