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.
