Polaris 3900 Sport WMS Assembly w/ O-ring (39-300)
The WMS assembly w/o-ring is a replacement part made by Polaris. It is made from the same high-quality materials as the original factory part. Making this a genuine OEM product.
This WMS assembly is the most important feature of this cleaner. This part uses the water that comes from the return line and disperses it through 3 water jets that are above the center opening. This creates a water vortex that sucks up dirt, debris, and other forms of mulch off your pool's surface and into the superbag above the cleaner.
One great troubleshooting tip, if the cleaner is not moving or operating incorrectly, could be due to the water jets on the WMS being clogged. You can take a fine object like a paper clip or pin and simply inject it into the jets. Moving it around in a circular motion and then running water through them via a garden hose or the hose from a kitchen sink. This clears out any build-up of deposits which should return the power to the cleaner, allowing it to operate properly.
