Haven't used a rubi one but have used a similar one mainly for slate flooring, it's a chore loading it and unless you have the rubber bung just right it will squeeze through behind the plunger. It does slow you up but for the likes of slate it keeps it cleaner and easier to finish. Apart from that it's the good old rubi washboy and sponge.
