Abstract: Wall-floor edge cleaning ability in a vacuum cleaner is improved by a disk brush positioned rim with its bristles capable of floor contact and the hard, unyielding parts entirely contained in a gap in a bumper guard affixed to an exterior side wall of the housing. A stub shaft, loosely penetrating an aperture in the said housing side wall, is rigidly affixed at one extremity to the hub of the disk brush and at the other extremity axially to a free, unfettered end of a revolvable brush roll, the said brush roll horizontally supported within the nozzle area between the housing side walls. The disk brush is consequently revolvable with the brush roll. The disk brush may join the stub shaft end on a slightly oblique plane to assure better agitation of a carpet nap and direct penetration of a wall-floor edge by the rim bristles. To facilitate assembly and replacement of worn parts, the members are removably joined.

Abstract: A vacuum cleaner with improved carpet-wall edge cleaning ability achieved by bringing a free brush roll cleaning end and its bristle tufts and beater bars into optimum proximity with the edge to be cleaned. Aligned bearing structures within which the brush roll revolves, conventionally disposed to fetter the brush roll ends, are placed so that at least one is positioned on an inner segment of the brush roll, leaving a brush roll cleaning end free, unfettered. The space vacated by the bearing structure so treated allows extension of the free brush roll cleaning end into loose abutment with the general housing material, the bristle tufts and the beater bars comparably extended. These latter members can now function closer to the edge to be cleaned, thereby performing better. Additionally, a cutout in the general housing and adjacent materials allows of further extension of the free brush roll cleaning end into space thus vacated.
