A hand vacuum cleaner with a finger grip area that is provided between a forward side of the handle and a rear side of the main body, and wherein the suction motor is positioned between the cyclone and the finger grip area and an axis that extends between the front of the cyclone and the handle extends through the suction motor.

A surface cleaning apparatus comprises an air treatment chamber, a pre-motor filter and a suction motor. The suction motor and the pre-motor filter are laterally spaced from the air treatment chamber. When the surface cleaning apparatus is positioned on a horizontal surface with the upper end of the air treatment chamber above the lower end of the air treatment chamber, the pre-motor filter is positioned at a higher elevation than the suction motor.
