Abstract
A surface cleaning apparatus comprises a hand vacuum cleaner, a surface cleaning head and a rigid air flow conduit extending between the surface cleaning head and the hand vacuum cleaner. The hand vacuum cleaner comprises a main body and a removably mounted air treatment member. The air treatment member has an air inlet and the outlet end of the rigid air flow conduit is removably connectable in air flow communication with the air inlet.
Claims24
A surface cleaning apparatus comprising:
- (a) a hand vacuum cleaner having a front end having a dirty air inlet, a longitudinally spaced apart rear end, a clean air outlet, an upper end and a bottom, the hand vacuum cleaner comprising:
- a main body comprising an upper end, a lower end, a front end and a rear end, the main body housing a suction motor and fan assembly, the suction motor and fan assembly having a suction motor axis of rotation;
- (ii) an air treatment member removably mounted at the front end of the main body, the air treatment member comprising an upper end, a lower end, a front end and, a rear end, the lower end of the air treatment member is rotationally mounted to the lower end of the main body, wherein one of the air treatment member and the main body is provided with an outwardly extending protrusion and the other of the air treatment member and the main body is provided with a groove in which the outwardly extending protrusion is received when the air treatment member is secured to the main body;
- and,
- (iii) an air treatment member release lock comprising a release actuator and first and second engagement members wherein the first engagement member is provided on the upper end of the air treatment member and the second engagement member is provided on the upper end of the main body and the release actuator is provided on one of the air treatment member and the main body,
- (b) a surface cleaning head;
- and,
- (c) a rigid air flow conduit extending between the surface cleaning head and the hand vacuum cleaner wherein an outlet end of the rigid air flow conduit is removably connectable in air flow communication with the inlet passage.
