The Hayward Max Flo XL VS pool pump is a powerful yet energy efficient 1.5HP option for circulating your pool water. Classic Hayward construction and reliability is combined with modern energy efficiency that provides up to 80% savings on energy costs compared to ordinary single-speed pumps. The VS stands for variable speed which allows you to control how much power you want your pump to output. With the Max-Flo VS you’ll be able to program your settings on the rotatable interface that’s full integrated into the pump, making operation and control much easier. The see-through container allows you to spot any clumps of debris that accumulate, taking the guess work out of when to clean the basket.
