Abstract: A surface cleaning head with a leading roller 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 surface cleaning head may have dual agitators—a leading roller and a rotating brush roll—with the leading roller being located in front of the brush roll. The leading roller may have a smaller diameter than the brush roll and may provide a softer cleaning element. The leading roller may also have a bottom portion exposed to the flow path to the suction conduit and at least a top half that is not exposed to that flow path. The leading roller may also float relative to the surface cleaning head and/or may be adjustable relative to the brush roll.

Abstract: A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening. The underside may define side edge vacuum passageways extending from the sides of the housing partially between the leading roller and the sealing strip towards the opening.

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.

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。
