Love it, bought one about 6 months ago from the chemical guys.  Got the green soap with it.  Don't need a bucket of soap anymore.  Still need to lightly scrub if you want something all the way clean.  Had an oil line blow under a versatile this fall.  Loaded the reservoir with degreaser soap.  It foamed the whole shop up, but dissolved all the hydraulic oil out from under it with no scrubbing.  Works great on implements that you normally don't scrub, you can get soap all over it and let it work.  It takes a bit more soap than they recommend to get a good foam out of it.  It's also good after using a tractor to spread fertilizer, I can foam soap all up in the under parts and let it neutralize the fertilizer that I normally don't get too.  I have tried other bulk soap from our napa and it works just as good.
