Mine does go to the wall a lot too, but it is doing an amazing job so far. From what I am seeing, it is getting every inch of the pool. It only comes to water line every 10 or 15 minutes and will go a pretty good distance before sinking back in. Not once has it been stuck anywhere and I have dual main drains. I probably won't use the timer feature much, I would be a little reluctant to leave it in the pool all the time. I think that would not be good on it. I am very satisfied with so far!!!
