发明名称 PUSH BRUSH CLEANER
摘要 <p>The push brush carpet or hard surface cleaner of the present invention is preferably comprised of a cleaning brush with a round surface area to which cleaning bristles of any conventional size and shape are attached. In practise the brush is preferably pushed over the carpet or hard surface to agitate and/or expel a debris-laden cleaning solution that has been previously applied to the carpet or hard surface to accomplish cleaning. The cleaning solution can be any conventional chemical solution suitable for the purpose of carpet or hard surface cleaning, but the brush of the present invention is preferably used in conjunction with a dry powder or substantially neutral pH dry crystalline formula cleaning solution for carpets. Finally, the optional axle, bearing and wheel configuration permits easy disassembly of the brush to allow easy replacement of the brush and to permit accommodation of various brush sizes and bristle varieties.</p>
