The Polaris 360 seen at this link claims to not need a booster pump, but I can't tell what sort off pressure and flow rate it really would need, but I suspect that at worst a split valve that reduced flow to the other return lines (when the cleaner was on) combined with a boost in pump flow would probably work. I just wish the mfgs were more specific with their specs. as it would make things easier to figure out.
