  • Patent number: 9706888
    Abstract: A vacuum cleaner having a housing and a suction inlet thereon, the cleaner comprising a suction source in fluid communication with the suction inlet to produce a working airflow therethrough and a dirt container in fluid communication with the suction inlet and suction source. The housing further comprises a body defined by a central portion and a pair of extension arms that extend laterally outwardly from the central portion, wherein each extension comprises a mount, which receives a rotatable agitator thereon. A drive assembly is configured to counter-rotate each agitator with respect to the other agitator, and wherein the suction inlet is positioned on the housing rearward of, and between, each of the axes of rotation of each agitator. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris outside the periphery of the housing along a converging debris path, towards the suction inlet.
