alt Hacker NewsThis is a shame. Unsure about later models, but my Roomba 620 is eminently repairable. Just last weekend I replaced the wheels with some original (from iRobot).
It'll still be going in another 10 years, but the AliExpress sourced parts are never of the same quality.
i have a roborock and pretty much every moving part is replaceable and unofficial parts are available on aliexpress for dirt cheap
