Guys - bumping an old post because we did get one of these - even if you don't use shampoo, it gets the whole dog wet and rinsed in under 5 minutes - fully bathed - which I do 1x a year in under 10 minutes...now, cleaning up the bathroom from the HAIR takes longer than that - but both dogs were willing to stand there for this thingy - it doesn't interfer with my shower at all - and they are all shiny again. It's pricy but I'd do it again in a heartbeat!
