it fits in mine nowjust about with the handle on and everything, i have a doblo with a flat tank so it tight but i just about can past the handle of the hose real, its possible to list in with about 10 litres of water in it, any more and its heavy, however you will be able to judge how much to use on most of your houses and it has a measure on the side, i think its a pretty nice bit of kit :-)
