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.

Abstract: A shampooer for nap surfaces which supplies shampoo in liquid form to an elongated distributor. A spongelike pad is mounted beneath the distributor and is generally coextensive therewith. A plurality of flexible beater rods are disposed with their tips confined between the pad and the nap surface. Oscillation of the rods causes them to alternately beat the pad to form foam, and to beat the nap to drive the foam thereinto for cleaning.
