Abstract

An upright vacuum cleaner includes a nozzle base (12) with at least one suction opening (60) formed therein. A rotatable brushroll (64) is positioned adjacent to the suction opening (60) for agitating a surface being cleaned. A suction source (54) is housed within the nozzle base (12). A dust cup assembly (70) is releasably connected to the nozzle base (12). The dust cup assembly (70) connects the suction source (54) and the suction opening (60) in fluid communication. A filter assembly (90) including a handle (101) is positioned between the dust cup assembly (70) and the suction source (54) to block the passage of dirt and dust to the suction source (54). A handle (10) is pivotally connected to the nozzle base (12) and includes an upper handle grip (22) including a hooked portion (24) for hanging the upright vacuum cleaner. First and second wings (74a, 74b) extend from opposite lateral sides of the dust cup cover (72) to facilitate the separation of the dust cup assembly (70) and the nozzle base (12). A power cord retainer (32) includes a stationary section (34) and a pivoting section (36) which is selectively opened and closed relative to the stationary section (34) to selectively define a cord retaining loop (38).
