Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
A vacuum cleaning attachment comprising, an elongated tube section adapted for coupling to a vacuum cleaner hose wand and being provided with at least one longitudinally elongated slot in the side of said tube section, and a cleaning brush element having an elastomeric, hollow head, said elastomeric head having a perimetrical groove adapted to be plugged removably into said slot and retained therein, said element having bristles projecting outwardly from said side of said tube section, said head providing means for allowing air flow past said bristles into said tube section, whereby the attachment can draw air past said bristles and into said tube section when air is drawn through said wand and said tube section.
