The PoolSkim is an award-winning automatic pool skimmer that connects to a standard 1-1/2 inch threaded return jet located on the side of your pool. An additional Polaris adapter is available for purchase if your pool does not have a threaded return. By collecting surface debris before it arrives at the skimmer box, the PoolSkim reduces the workload of the filtration system, thereby increasing its lifespan. It also works in conjunction with all suction pool cleaners making them more efficient.
