ABSTRACT OF THE DISCLOSURE A dust bowl of a hand-held vacuum cleaner is attached to a power unit using top and bottom latches which are actuated by pushing a single actuator button. Both latches are outside a sealed space through which air flows, and are thus not sources of air, soil or liquid leakage. A wishbone-shaped pusher transmits mechanical actuation forces from the actuator button for actuating the upper latch to a spring bar connected to a bottom latch cam. When the actuator button is pushed, the spring bar is correspondingly moved to release the bottom latch in coordination with release of the top latch. A forward support member of the power unit cradles a portion of the dust bowl to provide support and lateral stability between the elements. A tab extends from the bottom of the dust bowl to overlap a forward edge of the forward support member to provide further stability to the fit.
