One of the guys from my friends list got a roomba a few weeks ago, so I looked them up to see what he's been telling stories about all week.
I found this
video. They are the cutest things! I really really want one. Not necessarily for the cleaning - just for the entertainment value. Unfortunately, I'm not going to get one. They run close to $600. So I think I'll just watch the video every time I get in the mood.
Because in my mind? They hum happy little songs. Like R2D2.
