    Abstract: A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The distal section has a distal section length in the longitudinal direction that is greater than the cyclone outlet port length.

    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. At least one energy storage member is positioned in an energy storage chamber having an energy storage chamber wall. The cyclone air outlet faces the energy storage chamber wall whereby air exiting the cyclone chamber impinges on the energy storage chamber wall.

    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.
