i like this video much more than stock video. I like how all of the debris moves toward the center of the brush, allowing most of the brush to remain effective as opposed to the standard brush. I don't like that they seem too short. I learned to lay the roller so that it doesn't bite off the drive's protrusion. This has already happened and I had to send my bot in for repairs. So I now route it with some copper washers and everything seems fine.
