Abstract:
A system for cleaning a soiled surface and/or restoring the soiled surface to a slip resistant condition, the surface having soils and surface particles, the system comprising:a) compressor means for supplying an air stream, said compressor means being adjustable to a desired level of air pressure, said compressor means being in fluid communication with an air supply conduit;b) moisture reduction means in association with the air stream;c) entrainment means for entraining media particulates into the air stream comprising an amount of media particles, said entrainment means being adjustable so that the amount of media particulates entrained can be varied;d) media chamber means for storing the media particulates before entrainment in the air stream;e) restoration means for impinging the media particulates upon the surface to remove soils and surface particles, said restoration means being movable across the surface in any direction, said restoration means being in fluid communication with an exhaust conduit, wherein said restoration means comprises:i) a support frame including a plurality of wheels;ii) a nozzle having a longitudinal bore, one end of which is proximate the surface; andiii) an exhaust chamber in fluid communication with said bore and with said exhaust conduit;f) vacuum means in fluid communication with said exhaust conduit for an evacuation of substantially all of the soils and surface particles from the surface, wherein said vacuum means automatically adjusts to said level of said air stream of said compressor;g) classifier means for separating a portion of the media particulates from the soils and surface particles, said classifier means being in fluid communication with said exhaust conduit;h) automatic transfer means for transferring heavy media particulates from said classifier means to said media chamber means; andi) filter means for filtering the soils and surface particles, said filter means being in fluid communication with said classifier means, wherein said system etches the surface and increases the coefficient of friction of the surface.
