Abstract
A vacuum cleaner includes a foot assembly having a suction inlet thereon, a suction source in fluid communication with the suction inlet to produce a working airflow there through, and a dirt container in fluid communication with the suction inlet and suction source. The foot assembly further includes a body defined by a central portion and a pair of extension arms, a rotatable agitator on each extension arm, and a drive assembly configured to counter-rotate the agitators. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris towards the suction inlet.
