Review on 🧹 Neato Botvac Side Brush Belt 3-Pack for Models 65, 70e, 75, D75, 80, D80, 85, D85, D4, D5, D6, D7 Motors by Marshall Lindner

Works great so far. You'll need a fairly long Torx screwdriver to get at the motor that spins the side brush. The exchange took about 30 minutes. The old one was obviously worn and stretched. I've read complaints about replacements made from other material. Honestly I think this is done specifically to increase durability. Now the brush rotates quickly and evenly on the carpet. Time will tell if it holds up, but so far I'm very satisfied. It's better to send it to a repair shop and pay $100.
