Review on 🔧 EZ SPARES 2 Sets Replacement Robot Parts - Upgraded Tangle-Free AeroForce Extractor Set, Robot Rollers Kit for Roomba 800 & 900 Series by Theresa Mcdonald

I probably picked them for the same reason as many others - they're among the cheaper ones. Well you get what you pay for. They came in a set of two and the first set lasted less than a month before my Roomba kept throwing error messages until I replaced them with a new set. The second set also lasted about a month. cheap but good value for money. I will buy a better brand next time.
