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 translation: 可以使用具有双旋转搅拌器（例如，前导辊和刷辊）的表面清洁头来帮助捕获气流中的碎屑进入表面清洁下侧的抽吸导管 头。 导向辊通常定位在抽吸导管的开口附近并且在其之前。 旋转刷辊可以位于吸入导管中，其中前导辊位于刷辊的前面并与刷辊间隔开，从而在它们之间形成辊间空气通路。 导辊可以提供比刷辊更软的清洁元件，并且也可以具有小于刷辊的外径的外径。 表面清洁头还可以包括接触前导辊和/或在前导辊前方延伸的前保险杠的清除突起。

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.
