发明名称 Carpet cleaning machine with pattern-oriented vacuum nozzle
摘要 In one embodiment, a carpet cleaning machine includes a pair of spaced, long-bristled, counter-revolving brushes for stroking solvent-moistened cleaning granules into and across the carpet fibers. A shroud is disposed above the brushes and has a bottom surface spaced from the brushes. At least one independently-operable vacuum nozzle is provided and has an inlet for receiving the granules to be removed from the carpet. This inlet is located adjacent the bottom surface of the shroud and is positioned generally coincident with the throw pattern defined by the granules as they are cast against the bottom surface of the shroud by the brushes. The machine thereby applies cleaning granules to a carpet and more efficiently removes such granules therefrom by vacuuming following carpet cleaning. In a second embodiment, two inlets are used and similarly positioned coincident with the granule throw pattern.
