We have had an iRobot Roomba 880 since 2014 and use it very heavily (almost daily until the battery dies). While we swapped out brushes, rollers, a battery and even a motherboard (it's all the fault of birds and their drinking water), it never occurred to us that we could swap wheels. Well, it turns out that not only the wheels can be changed, but the performance of Roomba changes as well. fully. Some notable differences (besides the attached photo) are that the Roomba is faster and most importantly, no longer gets stuck between floors. I think since we used the previous one for almost 6 years the price of the wheels is pretty reasonable. It literally takes a Phillips screwdriver and 5 minutes to change wheels. First you need to remove the bottom + the battery cover (4 screws) and then the wheels (3 screws each). Enjoy!
