Small Metal Ringlets in Pool after using Dolphin Cleaner

I am finding small metal ringlets in my pool after running my Dolphin Diagnostic pool cleaner. These ringlets show signs of wear and are visibly broken pieces.

What is failing and what needs to be repaired?

ADMIN REPLY: I do believe that is the ball bearing retainer on the direct drive pulley. I expect you will see small ball bearings on the pool bottom soon.
