Our rumba is technically quite old. We did the usual brush and filter changes, but it never occurred to me to change his tires, let alone his chains. It recently slowed by a ton and a new battery could only help. It barely got over standard floor mats without snagging, so I turned it over and saw that one of the tire treads was completely worn out and its little spinning drive wheel was flat on one side. I felt like a monster! Cleaning it up like that was just cruel. New chains and wheels were replaced very quickly. Everything was easy to swap out and the little fella fiddles with rugs and floor mats like he did years ago straight out of the box. So before you give up your Roomba, try new protectors before you give up.
