Abstract

A vacuum cleaning including a nozzle base comprising a primary and secondary suction opening, a suction source positioned within a first cavity in the nozzle base, and a dust cup releasably positioned within a second cavity in the base. The dust cup comprises a first inlet in communication with the primary suction opening, a second inlet in communication with the secondary suction opening, and an outlet. An above floor cleaning tool is in communication with the second inlet. A first filter assembly is positioned adjacent the outlet of the dust cup. A second filter is positioned between the suction source and the first filter. An exhaust opening and filter are positioned downstream of the suction source to prevent particles from venting to atmosphere. The vacuum cleaner further includes a handle assembly comprising an elongated connecting portion and a handle. The handle is removable for use as a handle for an above-floor cleaning tool. The elongated connecting portion is removable for use as a wand for an above-floor cleaning tool. A hose is removably attached to the nozzle base and to the handle.
