PROBLEM TO BE SOLVED: To eliminate completely the risk of leaking a liquid such as water once sucked and soiling a floor or the like. SOLUTION: A flexible elastic blade 7 is provided in one long side 4a of an opening 4 formed in a slit in the head 2 of a nozzle body 1, and the elastic blade 7 is clamped by a blade clamp 10, and during cleaning, a liquid is scraped up together by the elastic blade 7 and sucked from the opening 4 and while not in use, the tip side of the elastic blade 7 contacts the other long side 4b of the opening by elasticity and closes the opening 4, eliminating the risk of leaking a liquid remaining in the liquid suction nozzle 13 from the opening 4 and soiling a floor or the like.
