Abstract
A handheld vacuum cleaner including an inlet, an outlet, and a dust cup having an aperture. The dust cup is in fluid communication with the inlet and the outlet and is configured to retain debris collected by the handheld vacuum cleaner. A fan is configured to draw air through the inlet and the dust cup and to discharge air through the outlet. A door is adjacent to the dust cup and includes the inlet. The door is movable between an open position to allow a user to empty the debris collected within the dust cup through the aperture of the dust cup and a closed position to inhibit debris from being emptied through the aperture of the dust cup and to allow debris to be collected through the inlet and through the aperture of the dust cup. A biasing member configured to bias the door toward the open position.
