Abstract: A shampooer for nap surfaces which supplies shampoo in liquid form to an elongated distributor. A rigid noncellular strip is mounted directly below the distributor, and a resilient sponge is secured to the strip. A brush is reciprocatingly driven into beating squeezing engagement with the sponge to turn the liquid into foam. The brush then carries the foam away from the sponge, deposits it on the carpet and works it in.
