PROBLEM TO BE SOLVED: To provide a device for cleaning ship bottom which is excellent in operability and can reduce the amount of a cleaning agent used. SOLUTION: A window glass 20 is arranged in the ceiling 12A of a traveling vehicle 12 and a water sprinkler 24 is installed above the window glass 20. The water of a storage tank 30 is fed to the nozzles 24A, 24A of the water sprinkler 24 to be sprayed under high pressure from the nozzles 24A, 24A toward a ship bottom 46. Freely stretchable/contractible covers 32 are installed around the water sprinkler 24 to recover water by them. The recovered water is sucked into a recovery pipe 38 together with air. After the air is separated by an air/liquid separator 42, and shellfish and the like are separated by a filter tank 44, the water is transferred to the storage tank 30. COPYRIGHT: (C)2005,JPO&NCIPI
