Review on 🧹 Hongfa Replacement for Roomba S9/S9+ Vacuum Parts - 18 Packs Replenishment Kits - Roomba S Series Robot Vacuum Accessories: Rollers, Filters, Side Brushes by Cindy Martinez

I bought these for parts when I bought the new S9+. When they were finally needed, they were very noisy and left the Roomba with an error on several occasions. I had two spare sets and tried both. Same problem. I've ordered OEM replacement rollers and I'm back in business. I don't normally have problems with Roomba replacement parts, but I had problems with these rollers.
