I have a Barracuda Classic that came with the pool. It has a pressure regulator attachment that is supposed to go on between the hose and the skimmer inlet. With it connected in any setting, the cleaner wil not work. My local pool store advised it is fine to hook directly to the skimmer.
So I did, it seems to be working as designed, there is a pulse in the line and the cleaner meanders around the pool. It will clean what it runs right over.
My chief conplaint is, even if in the pool for 3-4 hours, I can barely tell its done anything. The ouside edge is nice and clean, and a few paths on the bottom. It seems to not be random and get caught in a pattern.
I am using the barracuda sectional hose. The weight it where it should be, 1.5 meters back from the unit.
