(b) a cyclone bin assembly positioned in the air flow passage and comprising a bin first end, an opposed bin second end axially spaced apart from the bin first end in an axial direction and a cyclone bin assembly sidewall located between the bin first and second ends, the cyclone bin assembly sidewall surrounding a contiguous interior volume and comprising: i) a first sidewall portion extending at least nearly parallel to the axial direction and having a first width in a lateral direction generally orthogonal to the axial direction; ii) a second sidewall portion extending at least nearly parallel to the axial direction and having a second width in the lateral direction wherein the second width is narrower than the first width; iii) a third sidewall portion extending at least nearly parallel to the axial direction and disposed between the first sidewall and the second sidewall portion, the third sidewall portion having a third width in the lateral direction that is greater than the second width; iv) a first inclined transition portion connecting the first sidewall portion and the second sidewall portion and narrowing from the first width to the second width; and, v) a second inclined transition portion connecting the second sidewall portion and the third sidewall portion and widening from the second width to the third width. ### Claim 2 (depends on 1) The surface cleaning apparatus of claim 1, wherein the first width is generally equal to the third width. ### Claim 3 (depends on 1) The surface cleaning apparatus of claim 1, wherein the sidewall forms an exterior surface of the surface cleaning apparatus. ### Claim 4 (depends on 1) The surface cleaning apparatus of claim 1, wherein the cyclone bin assembly comprises a cyclone having a cyclone air inlet, a cyclone air outlet, an upper end and a lower end, the upper end of the cyclone is proximate the bin first end, the bin second end comprises a dirt collection surface and the cyclone air inlet is spaced from the dirt collection surface. ### Claim 5 (depends on 4) The surface cleaning apparatus of claim 4, wherein the cyclone bin assembly has a cyclone bin assembly air outlet that is provided in the bin second end. ### Claim 6 (depends on 5) The surface cleaning apparatus of claim 5, wherein the cyclone bin assembly air outlet extends through a dirt collection region provided in the bin second end. ### Claim 7 (depends on 5) The surface cleaning apparatus of claim 5, wherein the cyclone air outlet is provided in a lower portion of the cyclone. ### Claim 8 (depends on 6) The surface cleaning apparatus of claim 6, wherein the third sidewall portion is located at the bin second end, the bin second end has a bin second end wall and the second inclined transition portion and the third sidewall portion are located between the cyclone air inlet and the bin second end wall. ### Claim 9 (depends on 7) The surface cleaning apparatus of claim 7, wherein the bin second end wall is openable. ### Claim 10 (depends on 1) The surface cleaning apparatus of claim 1, wherein the cyclone bin assembly has a cyclone bin assembly air outlet that is provided in the bin second end. ### Claim 11 (depends on 10) The surface cleaning apparatus of claim 10, wherein the cyclone bin assembly air outlet extends through a dirt collection region provided in the bin second end. ### Claim 12 (depends on 10) The surface cleaning apparatus of claim 10, wherein the cyclone air outlet is provided in a lower portion of the cyclone. ### Claim 13 (depends on 11) The surface cleaning apparatus of claim 11, wherein the third sidewall portion is located at the bin second end, the bin second end has a bin second end wall and the second inclined transition portion and the third sidewall portion are located between the cyclone air inlet and the bin second end wall. ### Claim 14 (depends on 13) The surface cleaning apparatus of claim 13, wherein the bin second end wall is openable.
