  • (a) an air flow passage extending from a dirty air inlet to a clean air outlet;

    (b) a cleaner body housing having a rear end and a front end;

    (c) a suction motor positioned in the air flow passage, the suction motor having a motor axis and positioned in the cleaner body housing;

    (d) a cyclone unit positioned in the air flow passage, the cyclone unit comprising the dirty air inlet, an air outlet, a cyclone chamber, a dirt collection chamber, and a longitudinal axis extending between a front of the cyclone unit and a rear end of the cyclone unit, wherein a wall of the cyclone unit that is intersected by the longitudinal axis is moveable to an open position in which the dirt collection chamber is opened, wherein the cyclone unit is separable from the cleaner body housing as a closed unit and wherein the cyclone unit is removably securable to the front end of the cleaner body housing at the rear end of the cyclone unit and the cyclone unit is maintained in position by engagement with the front end of the cleaner body housing; and

    ,(e) a pre-motor filter positioned in the air flow passage upstream from the suction motor and having an upstream side and a downstream side wherein, when the cyclone unit and the cleaner body housing are separated, access to the pre-motor filter is provided;

    wherein the cleaner body housing comprises a portion housing the pre-motor filter and the pre-motor filter remains in position when the cyclone unit is removed, andwherein, when installed in the hand vacuum cleaner, the pre-motor filter has a diameter larger than a diameter of the cyclone chamber, andwherein the longitudinal axis of the cyclone unit intersects an upstream face of the pre-motor filter.
