Abstract: A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

Abstract: Vacuum cleaning devices include foldable wands to provide a storage configuration and/or facilitate use. A vacuum cleaning device includes a wand having a first end coupled to a vacuum unit and a second end coupled to a vacuum head or surface cleaning head. The wand defines an air passage allowing air to pass from the surface cleaning head to the vacuum unit and includes a flexible air passage along at least a portion of the wand. The wand also includes a plurality of segments pivotably connected together such that the wand is foldable about 180° in a forward direction until the vacuum unit is positioned proximate a top of the surface cleaning head, thereby providing a storage configuration.
