Electric vacuum cleaning apparatus and cleaning head

An electric vacuum cleaning apparatus comprising:

• an electric blower that generates suction vacuum pressure;
• a suction air passage equipped with a suction port and fluidly connected to a suction side of the electric blower;
• an electrolyzed-water generator that electrolyzes water to produce electrolyzed water containing hypochlorous acid;
• a wiping-member attachment to which a wiping member is detachably attached, the wiping-member attachment being displaced from the suction port in forward and backward directions;
• a supply mechanism that supplies the electrolyzed water to a surface to be cleaned;
• and
• a rotatable brush arranged in the suction port to be shifted in the forward and backward directions with respect to the wiping member, wherein
• the supply mechanism is configured to
• supply the electrolyzed water to part of the surface to be cleaned sandwiched between the suction port and the wiping member attached to the wiping-member attachment,
• at a time of moving in the forward direction in which the suction port and the rotatable brush move ahead of the wiping member, supply the electrolyzed water to the surface to be cleaned so that the wiping member wipes off the electrolyzed water on the surface, and
• at a time of moving in the backward direction in which the wiping member moves ahead of the suction port and the rotatable brush, shut off supply of the electrolyzed water to the surface to be cleaned.
