ABSTRACT:
A device for scrubbing carpet having a brush which rotates about a point which is eccentrically driven in a small circle. The bristled area of the brush has a number of protruding areas around its periphery. When the scrubber is used with powdered cleaning composition, the bristles in these protruding areas press the powder down into the pile of the carpet and so tend to minimize redistribution of the powder by the brush as it rotates. A press bar may be located at the front of the machine to press powder down into the pile of the carpet. Means may also be included for dispensing powder in front of the press bar.
