    CPC classification number: B65D81/24 B65D65/38 A01N59/20

    Abstract: A surface cleaning apparatus includes a momentum separator, which includes an outer liquid collection chamber and an inner solid collection chamber that is positioned within the outer liquid collection chamber and separated from the outer liquid collection chamber by an inner chamber wall. At least a portion of the inner chamber wall is porous. The air flow path comprises an inlet conduit that extends from the dirty air inlet to the inner solid collection chamber, and a downstream air flow path extends from the inner solid collection chamber to a suction motor and the porous portion of the inner chamber wall connects the inner solid collection chamber in fluid communication with the downstream air flow path. Air travelling through the inlet conduit enters the inner solid collection chamber in a first flow direction and air exits the inner solid collection chamber is a second, different flow direction.

    Abstract: A hand vacuum cleaner has a body portion housing a suction motor. An air treatment member assembly comprises an air treatment member assembly body, a rear door and an air treatment member. The air treatment member has a front end, a rear end, an air inlet and an air outlet provided at the rear end of the air treatment member. The air treatment member assembly is moveable to an emptying position. The rear door is moveable between a closed position and an open position, and the rear door houses a pre-motor filter that is external to the air treatment member.
