Review on CyberTech Replacement iRobot Roomba 3 Armed Side Brushes for 500, 600, 700 Series (Excluding 645, 655, 675 & 670, 671, 690) by Tommy Maynard

Inexpensive and easy. Unfortunately I had to struggle and spend many minutes trying to figure out why my old screw wasn't working with the new brush. There were two new screws in the brush set. Brilliant! No wonder the stew was short. The brush was not held in the gap. I had to use a drill to open up the plastic hole to install the old screw. Now everything works. I just don't have some more noise with my rumba. But now I have to find out what's going on. The brush spins, but then stops as the room moves. And again a brush with rotation. I wonder if it just takes a little time for the brush to break and become flexible.
