This is the NEW Navigator V-Flex & PoolVac V-Flex by Hayward. The V-Flex models are a substantial upgrade from the standard Navigator and PoolVac models. The V-Flex Turbine is a flexible turbine; the vanes collapse as water passes through the mouth of the cleaner allowing it to pick up larger debris.

Along with the upgraded V-Flex turbine, the A-Frame has also been beefed up with a larger longer lasting bearing and a redesign that will give this part a much better lifespan. If you're familiar with the old Navigator and PoolVac you know about swapping out the A-Frame and Turbine often as it wears down.

This design change is significant because it fixes two of the main issues with the Navigator and PoolVac, those being, the parts wear out fast, and small debris jams the cleaner. The old fixed turbine would just get jammed too often on debris. The V-Flex turbine won't have this issue. 

Both the Navigator V-Flex and PoolVac V-Flex are part of Haywards expert line. They are only available at your local pool store or if you are a pool service tech at your local wholesale distributor. They are not available online.
