The most technologically-advanced pressure-side pool cleaner on the market

The Polaris 3900 Sport delivers unmatched pool vacuum power, incomparable convenience, and legendary performance. It integrates the time-proven Polaris Classic series features you love with innovative new enhancements for added durability, reliability, and performance.

The Polaris 3900 Sport combines the dynamic appeal of a completely re-engineered body design with the most sophisticated features, producing maximum pool vacuum power and drive torque for quicker cleaning and fewer hang-ups. It features an all-wheel PosiDrive system with durable stainless steel drive chain that delivers 50% more torque for maximum speed and performance. And, it is equipped with a dual-chamber zippered SuperBag that picks up and stores more debris, making cleaning easy and less frequent. It also features innovative auto-reverse technology, which enables it to free itself if it gets stuck.

The Polaris 3900 Sport pressure cleaner works in all in-ground pools, and requires a booster pump. It supplements the pool’s filtration system by circulating an additional 40 gallons of water per minute through its filter bag. The 3900 Sport includes TailSweep PRO, an advanced sweep hose enhancement that blows debris out of corners and hard to reach places, while also keeping water from spraying outside the pool. No more wet windows or walkways!
