Abstract
A surface cleaning apparatus has a cyclone bin assembly having a cyclone chamber. The cyclone chamber with a physical filtration member defining the cyclone air outlet. The physical filtration member has an outer wall wherein at least a portion of the outer wall is porous and a plurality of ribs is spaced around the outer wall. The ribs have a radial inner side that has an inner width in the direction of rotation and a radial outer side that has an outer width in the direction of rotation that is narrower than the inner width.
Claims18
A surface cleaning apparatus comprising:
- (a) an air flow passage extending from a dirty air inlet to a clean air outlet;
- (b) a cyclone chamber positioned in the air flow passage, the cyclone chamber having an air inlet, an air outlet comprising a cyclone chamber outlet port, a cyclone axis of rotation, a first end and an axially opposed second end having the cyclone air outlet;
- (c) a physical filtration member positioned in the cyclone chamber upstream from the cyclone chamber outlet port, the physical filtration member extending inwardly into the cyclone chamber from the cyclone chamber outlet port, the physical filtration member comprising an outer wall wherein at least a portion of the outer wall is porous, and a plurality of ribs spaced around the outer wall, the ribs having a radial inner side, a radial outer side, an upstream side based on the direction of rotation, a downstream side based on the direction of rotation and first and second longitudinally spaced apart ends, wherein the radial outer side is positioned radially outwardly of the outer wall;
- and,
- (d) a suction motor positioned in the air flow passage downstream from the cyclone chamber
- wherein the radial inner side has an inner width in the direction of rotation and the radial outer side has an outer width in the direction of rotation that is narrower than the inner width.

A surface cleaning apparatus comprising:
- (a) an air flow passage extending from a dirty air inlet to a clean air outlet;
- (b) an air treatment chamber positioned in the air flow passage, the air treatment chamber having an air inlet, an air outlet comprising an outlet port, a first end, an opposed second end and an axis extending between the first and second ends;
- (c) a screen positioned in the air treatment chamber upstream from the outlet port, the screen extending inwardly into the air treatment chamber from the outlet port, the screen comprising recessed screen material and a plurality of ribs spaced around the screen, the ribs having a radial inner side, a radial outer side, an upstream side based on the direction of rotation, a downstream side based on the direction of rotation and first and second longitudinally spaced apart ends, wherein the radial outer side is positioned radially outwardly of the recessed screen material;
- and,
- (d) a suction motor positioned in the air flow passage downstream from the cyclone chamber
- wherein the radial inner side has an inner width in an angular direction extending around the longitudinal axis and the radial outer side has an outer width in the angular direction that is narrower than the inner width.
