Hi Greg and welcome to the forum.
19 batches so far... Wow! That's pretty good. How large were the batches?
Have you already ordered your RoboBrew yet? If not, are you open to other ideas? RoboBrew and lots of the other automated systems like that seem cool, but are subject to many of the "issues" of conventional 3V brewing. (Like needing to add rice hulls to avoid a stuck sparge, needing to run a separate sparge, etc.).
I think most of us would recommend doing Traditional Full Volume BIAB. So in a way it doesn't seem as cool...because you don't need as many "brew trinkets""... BUT...for us homebrewers, it usually works a little better - is simpler with less equipment to clean. Full volume mash is thinner and it helps us get higher EIB - Efficiency Into Boil (aka Brewhouse Efficiency, etc.). So it works better, and for those of us brewing normal homebrew size batches it doesn't have any downside...
I have a 16 gallon / 60 liter pot. Normal batch sizes for me of finished beer is 5 gallons / 19 liters into the keg (and 5.5 gallon / 21 liters VIF - Volume Into Fermenter). Traditional Full Volume BIAB with a large BIAB bag. Can do double batch without any adjustments, depending on OG, of about 9.5 gallons of a 1.050 beer. With a couple tricks I can get it up over 10 gallons...
So anyhow, if you are totally convinced you want your brew setup to be a RoboBrew (or any of the competitors to it on the market...or even conventional 3V brewing), more power to you... Brewing is fun and All Methods can make good beer! But for the homebrewer, brewing traditional homebrew volumes - there is no downside - and I think
many big upsides, to using
traditional full volume BIAB.
Let us know if you have any questions, and good luck!
