I've got that one too. Works really well. Some people think you need to cover your car in shaving-foam-thick suds, but that's not the point of snow foam. If you do your own car from time to time it's perfect. If I was a pro valeter I'd get one of the big capacity fancy ones, but for me the Karcher one is ideal. A full bottle (water and snow foam mix) easily does two cars, so it's easily big enough.
