Claim:
An electric vacuum cleaner, comprising: an electric vacuum cleaner body including an air intake opening and an exhaust opening with a suction air passage therebetween; a dust collector removably attached to the body along the suction air passage such that air containing dust which is sucked in through the air intake opening passes through the dust collector; a nozzle unit coupled to an air intake opening of the body and through which the air containing dust is provided to the air intake opening; handle coupled to the nozzle unit enabling a user to guide the nozzle along a surface to be vacuumed; an electric blower for creating suction through the suction air passage; and an ion generator which is disposed near the exhaust opening and which simultaneously generates H + (H 2 O) n as positive ions and O 2 − (H 2 O) m as negative ions which kill airborne germs; and an ion discharge port so formed as to discharge H + (H 2 O) n as the positive ions and O 2 − (H 2 O) m as the negative ions out of the body through a position thereof different from the exhaust opening.
