Phil--is that the Hayward "Ultra" vac? I was looking at those on Leslie's website. Does it have the flapper thingy like the Kreepy Krauly or does it have wheels? Does it "chug" around the pool or is it fairly smooth? Hope you don't mind a few questions... . I also have a dedicated suction line "vac outlet" on the sidewall of my pool and I agree that it's very handy.
