ABSTRACT:
A carpet vacuum cleaning machine and roller attachment apparatus therefor for cleaning and extracting dirt and debris deep below the surface of carpets. The carpet cleaning machine includes a vacuum head or housing operably connected to a vacuum source and a debris collecting member. The roller attachment apparatus preferably replaces the conventional elongated motor-driven roller brushes commonly used in most vacuum cleaning machines. The apparatus includes a plurality of spaced star-shaped spur discs mounted side-by-side for free rotation on an elongated support shaft. As the vacuum cleaning machine is moved across the carpet, the pointed periphery of each disc engages and penetrates into the carpet to separate the carpet fibers to expose dirt below the carpet upper surface thereby allowing more effective vacuum extraction of the dirt.
