Abstract
A dust collector includes a dust-collector main body, a coupling-hose part, an operation unit, and a belt or harness. The dust-collector main body serves to collect dust by generating a suction draft (partial vacuum). The dust-collector main body includes a housing, a motor, a dust-collection chamber, and at least one battery pack mount. The belt or harness is attached to the dust-collector main body and is designed for the user to carry the dust-collector main body on his or her back. The operation unit is connected to the dust-collector main body via an external, flexible cord. The operation unit includes one or more LEDs for illuminating the area to be cleaned and an ON/OFF switch for controlling operation of the motor.
