I've just received the latest Generation 3 RoboBrew without the pump. For 349 it's a pretty neat little system that can comfortably boil a 6.5-7gallon batch. 9 gallons out the end would be two brews worth of wort, no way I could see you getting that much out of this in one batch. It also would struggle to boil anything more than 7gallons with the 1500w base mounted element.
I actually utilize the GrainFather Profile for Beersmith and my numbers were nearly spot on for the first brew. I did augment the system with a chugger pump (I liked the idea of being able to service it, rather than having it built in) so I ran a recirculated mash just like you would with the GF or the Robobrew w/ pump.
For the price, it's a great little system. I have no complaints... but if it were nearer to grainfather pricing, I would say it's a little 'rough' around the edges... both literally and figuratively. I actually downsized from full single tier Electric-Brewery style setup so I definitely came in with pretty sky-high expectations.
