I bought one of those vacuum robots the other day, and I just got it in the mail. I have to say this Roomba thing is really neat, it goes around my house suking up everything in its path, and my dog is totally afraid of it, so it is funny! When you power the Roomba up, it makes this beeping noise that makes you think that it is happy to be awake and cleaning for you. I heard that people give their Roombas names, and we called ours Paco.
