Abstract
A hand carriable surface cleaning apparatus, such as a cyclonic hand vacuum cleaner, is provided wherein the pre-motor filter is positioned above the upper end of the cyclone chamber and downstream of a cyclone chamber.
Claims24
A hand carriable surface cleaning apparatus having a front end, a rear end and comprising:
- (a) a dirty fluid inlet;
- (b) a cyclone bin assembly comprising a cyclone chamber downstream of the dirty fluid inlet, the cyclone chamber comprising a lower end, an upper end, a cyclone axis, an air inlet and an air outlet at the upper end;
- (c) a pre-motor filter comprising an upstream side and a downstream side, the pre-motor filter is positioned in a pre-motor filter housing having an openable cover, the cyclone axis extends through the pre-motor filter housing;
- (d) a suction motor positioned downstream of the pre-motor filter and rearward of the cyclone bin assembly;
- (e) an air flow path extending from the pre-motor filter to the suction motor;
- and,
- (f) a clean air outlet downstream of the suction motor.
