Abstract: Abstract A surface cleaning head including a housing having a front side and back side, the housing defining a suction conduit with an opening on an underside of the housing between the front side and the back side and a brush roll rotatably mounted to the housing within the suction conduit and at least a portion of the brush roll being proximate the opening of the suction conduit and a leading roller mounted to the housing in front of the brush roll and spaced from the brush roll to define an inter-roller air passageway between a lower portion of the brush roll and a lower portion of the leading roller, wherein at least an inside of the lower portion of the leading roller is exposed to a flow path to the suction conduit and wherein at least an inside of an upper portion of the leading roller is substantially outside of the flow path to the suction conduit, wherein the leading roller has a diameter ranging between 0.3 and 0.8 times the diameter of the brush roll, and wherein the leading roller includes a cleaning element that is softer than a cleaning element of 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 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.
