This dome keeps all of the mess inside the machine. It snaps down with three attached ridges molder into the dome, it cleans inside and out in one minute with a garden hose or shower head. And this dome is much heavier, thicker and more durable than any of the others, as far as I can see. --p.s. When kids starting eating, then there is some mess on the floor or deck, so we only use our outside, although a garage would work fine also.
