摘要： A gravity feed liquid cleaning solution supply system particularly suitable for use on an upright hot water carpet extractor having a free floating brush assembly is disclosed. The unique system generally comprises a stationary fluid supply manifold positioned above a free floating brush assembly having multiple laterally disposed rotary brushes rotatable about vertical axle shafts suspended from a laterally disposed brush support beam. The support beam includes open top troughs, one above each individual brush, into which liquid cleaning solution cascades from the overhead manifold. From each fluid trough, the cleaning solution is conveyed to the center cup of an associated rotary brush through a conduit integrally molded into the brush support beam. By this unique structure liquid cleaning solution is supplied to the free floating brush assembly without restricting the floating movement of the scrubbing brushes over the surface being cleaned.
