We have had it for a week now and used it a few times. We ran it on the 3 hour timer the first time and was amazed at how much it picked up. Now we just throw it in on the 1 hour timer every now and then to keep the pool sparkling clean on the bottom.
Even with our 7 foot deep end it seems to hit the entire pool and it does climb the walls with no issues. So far this thing gets 2 thumbs up from us. No more dragging the hoses out and spending an hour vacuuming only to find we've missed 25% of the gunk anyway. The pool has been the most clean since we have bought this thing.
And we scored it for $525 on sale!
