Abstract (en)
[origin: US2017209009A1] A vacuum cleaner power nozzle adjustable for use on low- and high-pile carpets. Vent openings across the front of the nozzle selectively open to introduce a secondary flow of air at the leading side of the roller brush of the nozzle. The secondary flow of air reduces resistance to movement of the power nozzle over high-pile carpet, and is drawn under the rotating roller brush to aid in displacement and removal of particulate from the carpet.
