Rotary processing for daylight tanks?

I just found this on the Frugal Photographer website.

"Compact Developing tank with two spiral reels, light-tight lid for rotary agitation, liquid-tight lid for inversion or rolling agitation, and instructions."

What I want to know is if there are actual methods for rotary agitation or rolling agitation with small tanks and how to do it.

I presume it's talking about something like this:

Or the motorized ones, like the Unicolor Uniroller motor base.

Is that what you're talking about?

Here is a better photo of the business end of a Jobo.

The Jobo CPA requires you to use Jobo's specialty tanks though. For that generic daylight tank you'll need a generic roller. The unicolor and beseler motor bases are just spinning wheels that you can drop any old tank on, right? I might be wrong... I've never used one.

That Jobo roller base I linked to is literally just 4 rolling wheels... you can put a tank on it and roll it manually. I have no idea why you would.
