That is about the most retarded thing I have seen. That may wipe the barrel after the shot (once) but it certianly isn't what I would call cleaning a gun. I have the same thing at my house, it is a sock tied to a small rope. Drop the rope down the barrel and pull the sock through. Pretty simple and cheap if you ask me. Or you could not be a cheap SOB like me and just get a Bore Snake
