PURPOSE: To dispense with the action to draw a main body and eliminate the limitation of a cleaning range by constituting a cleaner with the cleaner main body, a storage battery serving as a power source, and a shouldering tool shouldering them on the back.

CONSTITUTION: This cleaner is constituted by providing a cleaner main body A, a storage battery B, and a shouldering tool, and the storage battery B is stored in the main body A. The shouldering tool comprises two shouldering cords 1, a male buckle 2, a cord reel 3, and a female buckle 4. Since the main body A and the storage battery B can be shouldered on the back by the shouldering tool, both hands are made free, the drawing action of the main body A is eliminated, and a user can be devoted entirely to the action of a nozzle. Since the storage battery B is used as a power source, there is no limitation by a power cord, and the moving range is not limited. When this cleaner is used, both hands are made free, the moving range is not limited, and the cleaning work can be easily and quickly conducted by anyone at any place.
