A convertible vacuum-blower which includes a housing having an air inlet and an air outlet is disclosed. A motor and an impeller are supported in the housing. The impeller is supported for rotary motion and is driven by the motor. The impeller is in fluid communication with both the air inlet and the air outlet. The air inlet is selectively covered by an apertured, removable air inlet cover. A mechanism removably secures the air inlet cover to the housing. A switch mechanism is carried by the housing and allows the motor to operate when the air inlet is covered, but not when the air inlet is uncovered. A first switch actuator is carried by the air inlet cover for actuating the switch mechanism when the cover is secured to the housing covering the air inlet. A removable vacuum nozzle also includes a second switch actuator for actuating the switch means when the vacuum nozzle is secured to the housing covering the air inlet.
