A motor-driven outdoor vacuum has a ground level intake and a hose intake. When a hand-operable actuator moves a first or main door into a ground pick-up position, the ground level intake, which is carried by the first door is in direct air-flow communication with the impeller and the hose intake, which is carried by the first door is closed by a spring-actuated second door carried by the main door. When the actuator is moved to a hose intake position, the main door is moved to a second position in which the hose is in air-flow communication with the impeller and the ground level intake is closed.
