This part is designed to spin while allowing the wide trax tire to help the cleaner to move along the bottom surface of your pool. It also allows the cleaner to climb up and down the pool walls providing a deep clean. There are two wheel bearings on each side of the wheel that gives it the ability to spin in either direction with ease.
There are three of these parts and they are placed two on one side of the cleaner and locked into the frame and bottom housing. The third is placed on the opposite side.
