We had a roomba because we had two black labs that shed like crazy - and a cat. The darn thing would either choke on the dog hair or get wedged under the several pieces of furniture. We had to roomba proof the room with all sorts of cushions so the thing woudln’t get stuck or try to vacuum up electric cords. And then there was zero programming so it was totally random and missed big areas, besides going into the bathroom and closing the door on itself and bumping itself until its battery died. Gave the thing away to the Goodwill with lots of bad will.

There needs to be one that is methodical using a grid and can be programmed to the grid or recognize furniture and not go cave diving and get stuck - at least they have auto empty when the start getting full these days, but don’t know how much they have improved since am not interested in dumping a wad of cash on another.
