Review on Interchangeable Wheel Module Pair for iRobot Roomba 500, 600, 700, 🔄 800, and 900 Series - Compatible with 880, 980, 960, 860, and 864. by Susan Foley

I bought this one thinking wow it's expensive to keep my little Roomba running. It crashed often and I often stopped using it. My old wheels were worn out. These new ones work better than the original ones. Great. Now Roomba rarely gets stuck. I've also learned to use blankets and towels to keep him away from places I know he might have problems. This purchase was worth the money. I highly recommend it.
