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.
