Question: What I picture is water everywhere on a cement floor with a drain...that can't possibly be right so how exactly does the overflow thing work? I mean, you would need to focus it somewhere, a hose maybe?, so that it could go to a drain and not make an unholy mess of everything...so how do you do that?

There are many fine example of members auto water changers or drip systems is the DIY sub forum. HAve a look there and then post a thread to ask specific questions. Some have the water go down a drain some have the water flow to a garden to water their veggies, or lawn.
