My dad had moderate success with Anker robot vacuums, but to my knowledge none of the robot vacuums are particularly good at tight corner type areas, so it'd mostly be useful for crumbs that are out in the open. I don't know what your threat model is for crumbs.

I got an ILIFE V3s Pro a few years back because it's dumb (don't buy Internet-connected household appliances if you can help it). I thought it was fine but I haven't used it much recently because the battery died and I misplaced the other battery and also my wife doesn't like it. (My dog doesn't like it either but she does not get a vote.)
