Specification Brand : ATIE BulletPoint1 : Compatible with Polars 280 Black Max pool cleaner BulletPoint2 : A hub part that takes the high-pressure water that is fed from the return line via the booster pump and feed hose, then distributes high-pressure water into 280 black max pool cleaner's Sweep Hose, Water Management System K25, and Turbine Drive Shaft assembly C86, creates the driving power, vacuum suction, and sweep power of the pool cleaner BulletPoint3 : Check the feed pipe every 2 to 3 pool seasons and replace it if there is leak or crack. BulletPoint4 : Package included: 1 pcs black feed pipe K31 and 1 pcs sweep hose adjust screw B20 BulletPoint5 : Assembly (Final Step): To attach the new pod, reverse the sequence described above. The pods are marked "R" and "L". Make sure you select the "R" pod. Press the new pod onto the end of the A-Frame. Secure the pod with the hex screw - make sure you include the small washer. Insert the pod plug and tap it in with the end of the screwdriver. Repeat steps 1-4 to replace the left pod. BulletPoint6 : Easy to install, just need 2 screwdrivers. As another poster stated, the plugs were too small so I reused the old ones. These new pods will last about 2 years in my older pool, based on my last replacement. I originally just purchased the wings and pod shoes, but when I took off the old ones it was clear the pods were shot as well. Next time I will purchase all together. BulletPoint7 : Tip: if you replace the pod shoes, for easier installation put the shoes on the new pods BEFORE you install. Channel locks work great for this because you have to push hard to get them on. Use a towel over the new shoe, then use the channel lock to squeeze into place. So much easier.

It then distributes high-pressure water into 280 Black Max pool cleaner's Sweep Hose B6, Water Management System K25, and Turbine Drive Shaft assembly C86. High-pressure water goes Turbine Drive Shaft assembly to create the driving power of the pool cleaner wheels. High-pressure water also goes into the Water Management System creating a vortex that sucks and pulls up dirt, debris, leaves, and other forms of mulch off of your pool's surface into the filter bag. High-pressure water also goes into the Sweep Hose to scrub and sweep debris from pool floor, walls, corners, and steps. Check the feed pipe every 2 to 3 pool seasons and replace it if there is leak or crack.
