    Abstract: A robotic cleaner may include a housing, an agitator, and one or more projections. The housing may have a front side, a back side opposite the front side, a left side, and a right side opposite the left side. The right and left sides extend between the front and back sides. The agitator may be configured to rotate about an agitator rotation axis, the agitator rotation axis extending substantially parallel to the front side. The one or more projections may extend from the housing. The one or more projections may include one or more cliff sensors.

    Abstract: A nozzle having castellations provides high suction pressure while also allowing for large pieces of debris to pass through inlet openings. In more detail, a nozzle for a surface treatment/cleaning apparatus is disclosed herein. The nozzle provides a suction channel through which debris passes into a main body of the surface treatment apparatus. Castellations are provided along a leading edge of the nozzle to allow debris to pass through the leading edge to the suction channel, and into the main body during, for instance, forward and reverse strokes of the surface treatment apparatus. In an embodiment, the castellations further include receptacles/cavities to receive and securely hold wheels therein. The wheels may extend from the nozzle at a predefined angle, also referred to herein as a camber angle, to improve vacuum handling and reduce noise during operation.

    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.
