I currently have a Hayward Tigershark. It cleans the pool well, but it also has some annoying habits so I and up having to "babysit" it (and quite often have to turn it off, or pick it up and throw it into the pool to stop it from hanging up on things).

I was looking at a Hayward Sharkvac as I would like to get one that doesn't climb the walls, just cleans the bottom. Does anyone have any experience with this one?
