I have a 1.5HP Jandy pump that feeds all of the returns, waterfall, 2 deck jets and the cleaner line in my pool. What I have found is that you can't possibly run them all at the same time, but that's OK....I'm not usually running the water features while my Poloris 360 is cleaning the pool anyway. At times I wish I had just a bit more force so I could push a good steady amount of water both through my waterfall, the deck jets AND the returns (to maximize circulation in the pool), but I certainly use this single pump for my Polaris and it works fine.
