主权项

1. A hand vacuum cleaner comprising:
a) an air flow passage extending from a dirty air inlet to a clean air outlet; b) a cleaner body comprising a suction motor housing having a suction motor that is positioned in the air flow passage and a pre-motor filter chamber positioned upstream from the suction motor housing, the suction motor having an air inlet and an axis of rotation, the pre-motor filter chamber having an axially extending sidewall; c) a cyclone unit positioned in the air flow passage and comprising at least one cyclone having a cyclone air inlet and a cyclone air outlet, and at least one dirt collection chamber wherein the cyclone unit is removable from the cleaner body, wherein the cyclone unit is sealed when removed from the hand vacuum cleaner other than the cyclone air inlet and the cyclone air outlet; d) a pre-motor filter positioned in the pre-motor filter chamber, the pre-motor filter comprising a porous filter media having an upstream face, a downstream face and a perimeter face extending between the upstream and downstream faces, the pre-motor filter being upstream of the suction motor and overlying the suction motor air inlet, wherein a projection of the axis of rotation extends through the upstream and downstream faces of the pre-motor filter from a downstream side thereof to an upstream side thereof,
wherein the pre-motor filter is recessed into the pre-motor filter chamber with the perimeter face facing the axially extending sidewall of the pre-motor filter chamber so that engagement with the axially extending sidewall of the pre-motor filter chamber retains the pre-motor filter in position when the cyclone unit is removed from the cleaner body, andwherein the pre-motor filter is removable from the cleaner body without reconfiguring the hand vacuum cleaner once the cyclone unit is removed from the cleaner body; and, e) a handle having first and second ends each of which is secured to the cleaner body.
