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.
Claims20
A surface cleaning apparatus, comprising:
- a housing;
- at least one rotatable agitator located on the housing in juxtaposition with a surface to be cleaned, the at least one rotatable agitator adapted to be dampened;
- a suction inlet;
- a suction source to produce a working airflow;
- a dirt cup in fluid communication with the suction inlet;
- and
- a dirt inlet ramp forms a bottom wall of a dirt path from the suction inlet to a dirt ramp outlet and the dirt ramp outlet is fluidly coupled with the dirt cup;
- and
- wherein the surface cleaning apparatus is configured to provide a manual damp mopping by manipulating the surface cleaning apparatus over the surface being cleaned without activating the suction source.
A surface cleaning apparatus, comprising:
- a housing mounted to a handle or wand assembly;
- a suction source to produce a working airflow;
- a filtration system to remove debris from the working airflow generated by the suction source;
- a suction inlet;
- a dirt container positioned in at least one of the handle, wand or housing;
- a first agitator located on the housing in juxtaposition with a surface to be cleaned;
- and
- a working air conduit extending from the suction inlet and the dirt container, wherein, when the suction source is active, the suction source draws debris through the suction inlet, along the working air conduit for collection into the dirt container, wherein a portion of the working air conduit forms an intermediate collection chamber, the intermediate collection chamber being removable from a stored position in the housing, wherein when the suction source is not active, manual movement of the housing over the surface being cleaned rotates the first agitator and transports debris removed from the surface being cleaned by the first agitator into the suction inlet and into the intermediate collection chamber.
