Both the SwimEx and the Endless Pool offer a better flow than standard jetted swim spas. Endless Pools use a propeller to push a water flow that is about 21" wide and 18" deep, located in the middle of the pool. It is a narrow flow and, depending on the swimmer, may be too narrow for effective swimming.
Using its paddlewheel technology, SwimEx Pools provides a wider and deeper current than an Endless Pool so you can be anywhere in the pool and still take advantage of the current. Imagine a consistent wall of water as wide as the pool and up to 30" deep. SwimEx offers the deepest and widest current flow on the market.
Finally - it's about the flow: the current in a SwimEx pool has 99 speed settings and moves up to 30,000 gallons per minute in a smooth river-like current. Endless pools move up to 5,000 gallons per minute.
