I have the ez vac and it doesn't get clogged on anything unless it's too big (big leaf or stick). It does a good job but tends to get stuck around the ladder. It cleans about 85% of the floor with the other 15% getting clean by my guidence.

It is affected by the pool's currents and I can't have my return circulate the water the way it normally does.

I haven't used a leaf canister along with it as I just open the strainer in the pump and take that out after vacuuming.

I've used it for 4 years now and not knowing anything else I would say it's worth it, I would think any AG cleaner would get stuck around the ladder.
