Robot vacuum brush motor pulsing

Decided to pop the bearing off while doing my periodic cleaning of the robot vac. I have a dog that sheds so much that some of her hair is still in a cabin in Colorado, and she didn’t go with us.

According to my Wyze app, the main brush has 67 hours remaining. I was an early adopter, so the main brush has been replaced several times. I would be interested to see what your robot vacuum picks up after a few cleanings.
