Held together with screws, which is the whole point

It never got a proper name. It's the 2006 Roomba Discovery that cleans a workshop on a regular basis, and it has been repaired several times, which works because it's held together with screws and built to be opened. Plenty of newer robot vacuums are glued or clipped shut, and those head for the bin once the first battery wears out. This one just got a new battery and went back to work on a floor that needed it. Its owner taught teenagers to solder for years and figures anybody can learn.
