    Abstract: A hand vacuum cleaner has a cyclone assembly having a cyclone with a central longitudinally extending axis wherein, when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner, the central longitudinally extending axis is oriented generally horizontal. The cyclone assembly has a cyclone assembly height that extends between an upper end of the cyclone assembly and a lower end of the cyclone assembly with a medial portion of the cyclone assembly positioned between the upper end and the lower end of the cyclone assembly. A housing containing the suction motor is positioned rearward of the cyclone assembly and extends downwardly from the upper end of the cyclone assembly to the medial portion. A pistol grip handle is positioned rearward of the cyclone assembly, below the housing and extends downwardly from the medial portion.
