1. A surface cleaning apparatus comprising:
- (a) an air flow path extending from a dirty air inlet to a clean air outlet and comprising a suction motor and a filter housing downstream from the suction motor, wherein the suction motor is external to the filter housing;
(b) a main body comprising a front end, a rear end spaced apart from the front end in a direction of travel of the main body and a central portion housing the suction motor, wherein the main body comprises a first sidewall and a spaced apart second sidewall and the central portion comprises a cavity located between the first sidewall and the second sidewall, the cavity having a platform;
(c) an air treatment member removably mounted within the cavity, the air treatment member comprising having opposed end walls, a bin sidewall extending between the opposed end walls and a lower surface, when the air treatment member is mounted in the cavity the air treatment member is in the air flow path, the lower surface rest on at least a portion of the platform and a rearward facing portion of the bin sidewall is visible from the rear end of the main body;
(d) a pair of spaced apart main wheels mounted to the main body on either side of the central portion and having an axis of rotation; and
,wherein the filter housing comprises a distinct body having by an outer perimeter wherein upper, lower and side portions of the outer perimeter are visible when the surface cleaning apparatus is in use.

15. A surface cleaning apparatus comprising:
-
(a) a main body comprising a front end, a rear end spaced apart from the front end in a direction of travel of the main body, a central portion, a suction motor and a filter housing, wherein the main body comprises a first sidewall and a spaced apart second sidewall and the central portion comprises a cavity located between the first sidewall and the second sidewall; (b) an air flow path extending from a dirty air inlet to a clean air outlet and comprising an air treatment member removably mounted in the cavity, wherein the cavity is open so that an upper surface of the air treatment member is exposed when the air treatment member is mounted in the cavity and whereby the air treatment member is removable from the cavity by lifting the air treatment member upwardly in the absence of removing any closure panel that closes the cavity during use of the surface cleaning apparatus, the air treatment member comprising a dirt collection chamber; (c) the filter housing extending from the central portion and comprising a top wall, a bottom wall, at least one sidewall and at least one end wall that are distinct from the main body, when the air treatment member is mounted in the cavity the dirt collection chamber overlies at least a portion of the filter chamber; and (d) a pair of spaced apart main wheels mounted to the first sidewall and the second sidewall on either side of the central portion and having an axis of rotation, the main wheels having a rearmost surface in the direction of travel of the main body and wherein the at least one end wall of the filter housing is disposed rearward of the rearmost surface of the main wheels in the direction of travel of the main body. - View Dependent Claims (16, 17, 19)
