ABSTRACT:
A rug cleaning attachment for a vacuum cleaner is disclosed. The attachment has a suds confining chamber and a scrubbing brush roll mounted thereon for rotation about a horizontal axis within the chamber. The brush roll has a multiplicity of tufts which are adapted to scrub suds into the rug and which define a cylindrical envelope upon rotation of the brush roll. A shield closely conforms to the cylindrical element and guards against suds being centrifugally thrown into the drive and/or suction components of the vacuum cleaner. A scalloped doctor blade is provided for the brush roll which projects into the cylindrical envelope defined by the tufts to scrape spent suds and lint from the brush roll.
