I currently have the kreep krauly and it's "ok" kind of a pain actually. I have trees and so forth around my pool and one little twig the size of a pencil lead will stop it in its tracks. I'm getting and electric robotic type next year. They also say it can cost up to $3 per day to run the suction type cleaners due to pump demand.
I'm just not a fan of the suction cleaners. My pool also has lots of turns, seats, and steps and it gets stuck in corners. Good luck.
