Abstract:
An apparatus for cleaning a surface comprising: an elongated tubular handle having a passage, a cleaning head connected to the handle, means for providing a vacuum to the passage of the tubular handle, tubular means for carrying a liquid located within the passage of the handle to the cleaning head, pump means connected to the tubular means operable to supply liquid under pressure to the tubular means, valve means connected to the tubular means for controlling the flow of liquid through the tubular means, said cleaning head having a rigid cylindrical first member with an internal chamber open to the passage in the handle, a plurality of first holes in the first member open to the chamber, means securing the first member to the handle, a cylindrical core rotatably mounted on the first member, a plurality of second holes in the core open to the first member, a scrubber located around said core, said scrubber having a rigid cylindrical second member telescoped over the core and rotatable with said core, said second member having third holes open to the second holes in the core, an open helical ribbon of abrasive material secured to said second member and projected radially outwardly from said second member, and a second helical ribbon of porous material located between the first ribbon secured to said second member and projected radially outwardly from said second member operable to dislodge particulates, dirt and films from a surface and allow air, liquid, particulates, dirt and films to move through the porous material into the internal chamber, a tube located in the internal chamber of the first member connected to the tubular means for accommodating liquid from the tubular means, means mounting the tube on the first member, nozzle means connected to the tube operable to direct liquid into the second holes in the core and third holes in the second member whereby at least the second ribbon spreads the liquid on the surface to be cleaned, said liquid on the surface being drawn through the scrubber along with air, particulates, dirt and films by the vacuum into the chamber of the cylindrical member and passage of the handle.
