Abstract: A surface cleaning head may be configured to receive a removable rotatable driven agitator, such as a brush roll, or a non-driven agitator. Either of these agitators may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The non-driven agitator may include an agitator body including a bottom portion supporting one or more cleaning pads. The non-driven agitator body may also define one or more air inlets, an air outlet and an air passageway extending therebetween to facilitate air passage through the surface cleaning head. Different removable agitators with different characteristics may be used interchangeably in the surface cleaning head.

Abstract: A surface cleaning head includes an openable agitator chamber to provide access to an agitator, such as a brush roll, for purposes of removing debris and/or removing the agitator. The openable agitator chamber is covered by an external cover that is movable between an open position and a closed position. A sealing member may be located between the external cover and a surface cleaning head housing and around a perimeter of the agitator chamber. A surface cleaning head includes a removable rotatable agitator, such as a brush roll, which is driven by a drive mechanism that axially engages the driven end. At least one end of the removable agitator may be secured in the agitator chamber by the external cover. The surface cleaning head may also include one or more transparent regions (e.g., on the openable cover) to allow visual inspection of the agitator during use.

Abstract translation: 表面清洁头包括可打开的搅拌器室，用于为了去除碎屑和/或去除搅拌器而提供进入搅拌器（例如刷辊）的通路。 可打开的搅拌器室由可在打开位置和关闭位置之间移动的外盖覆盖。 密封构件可以位于外盖和表面清洁头壳体之间并且围绕搅拌器室的周边。 表面清洁头包括可移动的可旋转搅拌器，例如刷辊，其由轴向接合驱动端的驱动机构驱动。 可移除搅拌器的至少一端可以通过外盖固定在搅拌器室中。 表面清洁头还可以包括一个或多个透明区域（例如，在可打开盖上），以允许在使用期间目视检查搅拌器。

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.

Abstract: A vacuum assembly having a hand vacuum configuration and a wand vacuum configuration may include a dust cup, a suction motor fluidly coupled to the dust cup, and a power source. The suction motor and the power source may be transitionable between a wand vacuum position and a hand vacuum position. When the suction motor and the power source are in the wand vacuum position, the dust cup, the suction motor, and the power source may be arranged serially. When the suction motor and the power source are in the hand vacuum position, the suction motor and the power source may be arranged in parallel with the dust cup.

Abstract: A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.

Abstract: An example of a vacuum pod may include a handle, a vacuum pod body, a dust cup removably coupled to the vacuum pod body, and a fluid conduit fluidly coupled to the dust cup. The fluid conduit may include a flexible hose configured to transition between an expanded and a retracted position and a coupling configured to be removably coupled to the vacuum pod body. A first end of the flexible hose may be coupled to the vacuum pod body and a second end of the flexible hose may be coupled to the coupling. When the coupling is coupled to the vacuum pod body, the flexible hose may be in the retracted position.

Abstract: A vacuum cleaner attachment generally includes a cleaning element that floats relative to a suction conduit of the vacuum cleaner attachment. The cleaning element is supported on a support structure that is movably coupled to a housing and is biased towards a floor, for example, as a result of the weight of the cleaning element support structure. The cleaning element may be permanently attached to the support structure or may be a removable or disposable pad or sheet attached to the support structure. The floating cleaning element may be supported between the suction conduit and one or more wheels of the vacuum cleaner attachment. The vacuum cleaner attachment may be removably attached to a vacuum cleaner, for example, to be used interchangeably with other surface cleaning heads.
