Bruno, I started to get very interested in that LG robot when they said it could mop floors, but I see they just mean you can put a pad on the back of it to act as a dry swiffer. I certainly don't call that mopping, but it's better than nothing. I do think that's quite a cool product, though. Have they said how much it's going to cost? Because right now it's going for $599 on Amazon, and that's just crazy. I don't know how these things can cost that much.

One thing I keep seeing is the criticism of how the Roomba cleans randomly. I agree that it should be smarter about what it does and know where it's going, but the unexpected benefit of the random pattern is that it gets the same area several times. The competition seems to imply that their robots need merely one pass to get it right, which I'm skeptical about given the power these things have. I've certainly seen my Roomba fail to pick up debris on the first pass and get it on the second.
