That Polaris 65 is one of the vacs that I use on my AG pool. It does a good job picking up big stuff --- twigs, leaves, etc., but not so good at dirt and dust. I mainly use that one in the spring when I first open and there is a lot of debris dropping from all the trees and then again in the fall when the leaves start falling. (I have trees around my pool.) Putting cotton balls in the bag does help it catch some of the smaller stuff but even with cotton, it doesn't do such a great job with picking up dirt. The swoosh of the tail as it moves around the pool gets a lot of the dirt stirred up into suspension.

For the rest of the summer, if I use something other than just doing it manually, I use a Wanda the Whale. Wanda is a suction-side cleaner. She walks around the bottom of the pool and does a pretty good job picking up dirt. But, she does sometimes have trouble staying on her "feet." I am noticing that issue more this year than in previous years for some reason.

Honestly, I can do a much better job just vacuuming the pool manually and I can do it faster, too. I actually don't mind vacuuming. It is too difficult to do from outside the pool, though. I just get in and mindlessly walk slowly around as I vacuum.

Hope this helps you some.
