Hydrofloors are specially designed pools with movable floors. When you’re using your pool it’s just like a normal pool. But when you are done swimming, you press a button and the pool’s floor slowly raises up while the water slips underneath the floor. Eventually the pool’s floor reaches the top and you are left with a large flat area you can use. You can also stop the floor at any point which to make the pool as shallow or deep as you want. You can even set it for shallow kiddie pool depth.
