International Classification:

A47L 5/22
A47L 9/00
A47L 5/36

Abstract:

A reconfigurable surface treatment apparatus may include a wand and a pod removably coupled to the wand. The wand may have a first distal end that is configured to couple to a surface cleaning head and a second distal end that is configured to couple to a handle. The pod may include a suction motor assembly cavity, a battery cavity, and a dust cup cavity. The suction motor assembly cavity and the battery cavity may be disposed on opposing sides of a vertical plane, wherein the vertical plane extends along a central longitudinal axis of the pod. The dust cup cavity may be disposed between the suction motor assembly cavity and the battery cavity such that at least a portion of the dust cup cavity is disposed on each side of the vertical plane.

International Classification:

A47L 9/04
A47L 5/26
A47L 5/30
A47L 9/30
A47L 9/06

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.

International Classification:

A47L 9/30
A47L 5/26
A47L 9/04
A47L 9/28

Abstract:

A vacuum cleaner includes a vacuum body defining an agitation chamber, an agitator, and an illumination system. The agitator is rotatably disposed at least partially within the agitation chamber and includes an agitator body defining an illumination chamber. The illumination system is at least partially disposed within the illumination chamber and includes at least one light source. Alternatively, a vacuum cleaner includes a vacuum body defining an agitation chamber, an agitator rotatably disposed at least partially within the agitation chamber, an illumination coupled to the vacuum body and including at least one light source, and a light guide configured to redirect light emitted in a first direction from the at least one light source to a second direction.

A47L 5/24

Abstract:

In general, the present disclosure is directed to a hand-held surface cleaning device that includes a relatively compact form-factor to allow users to store the same in a nearby location (e.g., in a drawer, in an associated charging dock, on a table top) for easy access to perform relatively small cleaning tasks that would otherwise require retrieving a full-size vacuum from storage. A hand-held surface cleaning device consistent with aspects of the present disclosure includes a body (or body portion) with a motor, power source and dust cup disposed therein. The body portion also functions as a handgrip to allow the hand-held surface cleaning device to be operated by one hand, for example.39

International Classification:

A47L 9/24
A47L 5/28

Abstract:

A flexible hose for use with surface cleaning devices is disclosed that includes a support structure that allows a user to collapse and lock the same into a storage configuration, and then easily unlock the same using a relatively minor amount of force, e.g., a user-applied pulling force or mechanical force. Thus, in a general sense, a hose consistent with the present disclosure may include two relatively stable/steady-state configurations, namely a storage configuration and an in-use configuration. Thus, the hose allows a user to collapse and lock the hose when not in use, and to transition the hose to an in-use configuration to target various types of surfaces to clean including, for instance, floors, walls and ceilings which may be many feet (e.g., up to 5 feet or more) from the surface cleaning apparatus.

A47L 9/00

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.

Abstract:

A hand vacuum cleaner has an air flow path extending from a dirty air inlet to a clean air outlet. An air treatment member and suction motor are positioned in the air flow path. The hand vacuum cleaner includes an onboard energy storage unit and has a pistol grip handle. When the hand vacuum cleaner is oriented with its upper end above its lower end, the pistol grip handle is located at the rear end of the hand vacuum cleaner, the energy storage unit is located at the lower end of the hand vacuum cleaner with the suction motor located above the front end of the energy storage unit and the pistol grip handle located above the rear end of the energy storage unit. A finger grip area may be provided between the handle and the suction motor above the energy storage unit.
