That requirement is going to focus you on cleaners with built-in pumps and filters. Not sure you want to do that. In most parts of Alabama, you're going to end up with a fair amount of grass and leaf debris in the pool, and the robot-vacs don't do so well with those.

A better plan might be to focus on a decent powered vacuum that collects debris, AND learning to operate your pool without algae.
