Pentair robotic pool cleaners are powered by low-voltage electricity, rather than your pool pump or a booster pump. Since your pump runs less, your energy costs are reduced. Plus, their built-in filter further reduces use of your pool's primary filtration system lowering energy costs even more, extending the life of both your pump and filter, and increasing the amount of time between filter cleanings. Robotic cleaners are also convenient, you just plug it in and place it in your pool. Some even have remote controls so you can steer the unit from a lounge chair for easy spot cleaning!
