I've got a roomba and a scooba. I've had a mint and a neato.
Roomba and Neato are comparable.
Roomba has the added bonus of having a little brush along the outside which grabs hair from under chair legs, along baseboards etc. The major downside is that it is round, so it doesn't get into corners, and it moves along like a drunk monkey (randomized movements).
Neato tracks like a major league lawnmover, perimeter first, then straight even lines. It doesn't have the side sweeper, but it has a flat face and can do corners.
I have loved all of my devices. They keep the floors clean, and added bonus, they keep the dust down. You've got to keep the floors picked up though, and can't have rugs with fringe or light electrical cords in reach (they can handle the wire for the tv or a lamp, but not an i-phone charger).
My kid and dog are terrified of them. So I have to operate them when they are not here. Buy from a place with a generous return policy in case that proves problematic for you.
Best,
F. B.
