ABSTRACT:
A vacuum cleaner of a detergent injection type uses a part of the suction force of a vacuum impeller actuated by a main motor to pump detergent to a remote cleaning implement. To this end, the vacuum cleaner includes a rotation device disposed in a passage of discharge air and rotated by discharge air and a pump device rotating simultaneously with the rotation device to pump up detergent to the detergent supplying device. Whereby, it has no need of additional motors and is made compact and economical in the construction.
