Pentair Racer Pressure Side Cleaner Water Management Kit (360261) 

The water management kit is a replacement part that was made by Pentair. Making this a genuine OEM product.

The water management system is the heart of the cleaner and it gets this title because it is the unit that transfers the high-pressure water that comes from the booster pump and filtration system to all the working parts that help the cleaner operate, just like a heart transfers blood throughout the body.

This part is gray and is in the shape of a circle that has a large opening in its center as it sits below the vacuum tube where it creates the vortex needed (via the venturi jets) to suck and pull up the debris off the surface so it can then be dispersed into the debris bag and disposed of at a later time. This part also works with other parts like the feed mast, timer valve, and rear thrust jet.

Great troubleshooting tip if the cleaner is not moving or operating the way it did when it was new, could be due to the venturi jets on the water management system 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. This clears out any build-up of deposits which should return the power to the cleaner allowing it to operate properly.
