Abstract
A dirt cup latching mechanism that secures a lid onto a dirt receptacle of vacuum cleaner and simultaneously secures the dirt cup in place on the vacuum cleaner. The latching mechanism presses the lid down onto an open top of the dirt receptacle and presses the dirt receptacle down into a dirt cup retaining recess provided in a generally horizontal wall of the vacuum cleaner housing. The latching mechanism may press down on the top of an open topped dirt receptacle, with or without a lid, while simultaneously pulling the dirt cup horizontally against a generally vertical wall of the vacuum cleaner housing. Thus, the latching mechanism simultaneously presses the dirt receptacle down against one of an inlet and outlet seal located on the horizontal wall of the housing and horizontally against the other one of inlet and outlet seal on the vertical wall of the housing, thereby sealing both the receptacle inlet and outlet.
