Title: Vacuum cleaners

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. Bristle tufts, implanted circumferentially on the said brush roll end, can be angled outward through the vacated space to contact unimpeded as the brush roll revolves the carpet-wall edge to be cleaned.
