A cleaner for the inside of a water tank is designed to draw up water stored within the water tank for aquarium fishes such as goldfishes, tropical fishes and the like to discharge the water to the outside. In this cleaner, a draw-up pipe is comprised of a body portion, and a grip portion connected at an angle of 90 DEG or more to the body portion. A first one-way valve and a second one-way valve are mounted within the draw-up pipe. Thus, the cleaner has a good manipulatability, so that air stored in the cleaner can be reliably discharged, and the discharging of water can be carried out reliably. <IMAGE> |
