The present invention relates to a portable stairway cleaning apparatus. The portable stairway cleaning apparatus includes a bag and an ejection-and-suction gun. The bag receives an air compressor for supplying compressed air; a water tank for supplying water with suction pressure created by ejecting the compressed air supplied from the air compressor at high pressure; and a vacuum suction device which collects dirty water by vacuum suction. The bag is carried on the shoulder of a worker. The ejection-and-suction gun for ejecting water supplied from the water tank through a water supply hose connected with the water tank and for sucking the dirty water on the surface of an object to be cleaned by being connected with a suction hose as the vacuum suction device is operated, using the high pressure compressed air supplied from the air compressor by being connected through the air supply hose and the suction pressure by a pressure of the supplied compressed air of high pressure so that one operator can complete the cleaning by jetting compressed air and small amount of water onto the floor surface of a stairway with the ejection-and-suction gun and collecting dirty water with the vacuum suction device. Since almost no water remains on the floor, an accident caused by a slip on a wet floor is prevented. |
