Abstract
A vacuum cleaner nozzle tool that is connected to a source of negative pressure and which functions to clean deep pile carpet or shag rugs in an efficient manner and which at the same time raises the pile of the rug or carpet in order to improve the appearance thereof. To achieve this objective the nozzle is provided with slide means of a particular configuration.
Claims7
A vacuum cleaner tool attachable to a source of negative pressure and for use with deep pile carpets or the like comprising an elongated tool housing which is operatively connected to said source of negative pressure, a plurality of suction nozzles each communicating with said tool housing, and terminating in an air intake opening;
- extending generally in a plane perpendicular to the underside of said housing, a plurality of surface engaging runners provided on the same side of said housing as said nozzles and each having a bottom surface thereof located at a greater distance below the underside of said housing than the air intake openings of said nozzles, each of said runners bridging a respective suction nozzle and disposed in a plane that is generally perpendicular to the length direction of said tool housing, and each of said runners dividing the respective suction nozzles in substantially equal sections whereby said runners slide in the direction of movement of said tool on the carpet work surface raising the pile and improving dirt removal from the interior of said carpet.
