  • VACUUM CLEANER POWER NOZZLE HAVING SELECTIVELY INTRODUCED SECONDARY AIRFLOW FOR OPERATION ON CARPETED SURFACES
    Publication number: 20170209009
    Abstract: 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.
