Change my mind: Roomba 105

I've been lurking on this sub for a while and it seems like Roombas have fallen out of favor. I like the price point of the Roomba 105 (vac only) and it seems like it meets my needs, so please tell me if I'm wrong.

I'm mostly just looking for something to clean up crumbs left by my kids and get under my couch once in a while. I wouldn't even use it in the bedroom area of the house, just dining room, kitchen, and living room (hard floors with a few area rugs). No mopping needed, doesn't need to replace deep cleaning, I just want to be able to walk in my house barefoot without stepping on food particles. We don't have pets. I do like the auto empty feature.

Is there something else that would be better at a similar price point (~$300)? Is there a reason it's worth going up to $500 even with these basic requirements?
