Abstract: An autonomous surface cleaning apparatus includes a body, a drive system carried by the body, and a cleaning assembly disposed at a front of the body. The cleaning assembly includes a housing defining a suction chamber and a suction channel extending from the suction chamber to a suction channel opening provided in a first side surface of the cleaning assembly, and a side suction nozzle mounted to an extension and retraction assembly that is arranged to allow the side suction nozzle to be moved between an extended position. The side suction nozzle includes a first resilient blade and a second resilient blade, the first resilient blade being arranged such that a surface of the first resilient blade is substantially forward facing and the second resilient blade being arranged such that a surface of the second resilient blade is substantially downward facing.

Abstract: A vehicle head or tail lamp assembly is disclosed. The lamp assembly includes a light emitter having a rectangular surface from which light is emitted; and a back surface having a light reflection factor less than 80%. The back surface defines a border visible adjacent at least three sides of the rectangular surface when the lamp assembly is viewed along an axis projecting normally from the rectangular surface.

Abstract: A cleaner head for a cleaning appliance, the cleaner head comprising: a housing defining a suction chamber; and a sole plate defining a downwardly-directed opening through which dirt can enter the suction chamber. The cleaner head further comprises a hollow deformable seal extending from a rear portion of the housing, the hollow deformable seal having a width at least equal to a width of the opening in the sole plate, and having a lower sealing surface that extends in a downward and rearward direction from a rear edge of the housing such that, in use, the hollow deformable seal is biased against and conforms to a surface being cleaned in order to maintain a seal between the cleaner head and the surface being cleaned.
