An upright vacuum cleaner includes an upper casing housing an electric motor having an output shaft and a suction fan mounted upon the output shaft. A cylindrical cyclone chamber is situated beneath the suction fan and has an inlet port, a longitudinal axis of the cyclone chamber being co-linear with the output shaft. There is a cylindrical dust receptacle situated beneath the cyclone chamber, a longitudinal axis of the dust receptacle being co-linear with the output shaft. A funnel delimits the cyclone chamber from the dust receptacle and a pickup head is situated beneath the dust receptacle and communicates with the inlet port via a duct.
