alt Hacker NewsThanks to the full Chinese supply chain, you can replace every single part of the roborock. Even if Roborock doesn’t sell it directly, someone does. I’ve owned a couple and I haven’t had any main board die. But you can buy anything from the wheels, to main board, to lidar online.
I liked how you could buy an official Roomba spare parts kit, though.
In a mechanical device meant for messy places, parts necessarily wear out quicker than in most electronics, and being able to buy and swap out the parts easily seemed like a nice feature.
