Another cleaner you might consider is ThePoolCleaner. Now owned by Hayward. It doesn't require a booster so it is more energy efficient. Based upon reviews, it cleans just as well if not better than the Polaris. I have the suction side version and it has been a great performer.

Also, the MaxFlo XL is another good Hayward pump and the 1 HP uses about 20% less energy than the 1 HP SuperPump.
