ABSTRACT:
The carpet cleaning device of this invention includes a liquid application means, liquid removal means and carpet brushing means. A reciprocating motion is provided to a pivoted brush by means of a rotary shaft having an oblique crank portion carrying a bearing whose outer race is connected to the brush. The shaft axis, center line of the bearing, and the brush pivot axis all intersect at a common point thus transforming rotary motion of the shaft to an arcuate, reciprocating motion of the brush.
