    Abstract: A hand vacuum cleaner has an airflow path from an air inlet to a clean air outlet with an air treatment member and a fan and motor assembly in the air flow path. The hand vacuum cleaner has a dirt collection chamber that is external to and connected in flow communication with a cyclone chamber by a gap located between the perimeter of an end wall of the cyclone chamber and a sidewall of the cyclone chamber or the dirt collection chamber. The gap is located only at an upper portion of the plate and/or is larger at the upper portion of the plate.

    Abstract: A surface cleaning apparatus includes an air flow path, a cyclone, and an air flow passage. The air flow path extends from a dirty air inlet to a clean air outlet. A suction motor is positioned in the air flow path. The cyclone is positioned in the air flow path, and has a cyclone chamber, a cyclone chamber sidewall, a plurality of tangential air inlets, a cyclone air outlet, and a longitudinal cyclone axis. Air rotates in a direction of rotation in the cyclone chamber. Each tangential air inlets includes an inlet port provided in the cyclone chamber sidewall, each inlet port having an upstream edge and a downstream edge in the direction of rotation. The air flow passage extends parallel to the cyclone axis and upstream from the tangential air inlets. The air flow passage has a terminal end at which the plurality of tangential air inlets are located.

    Abstract: A hand vacuum cleaner has an air flow path extending from a dirty air inlet to a clean air outlet and a suction motor positioned in the air flow path. A cyclone chamber positioned in the air flow path has a cyclone air inlet and a cyclone air outlet. A longitudinally extending battery pack which extend upwardly and forwardly when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner. A portion of the dirt collection region is located below a portion of the battery pack.
