Yesterday betsy found a roomba on craigslist. Today I went and got it. It is currently circling the basement on our nice new floor. It seems to be doing a pretty good job of not getting stuck. It did get caught under the sofa on the back side once. I freed it, now it's bumping it's way up and down the hallway. The dogs don't even notice it. I haven't seen the cat encounter it yet. Once it's done I'll empty it's little bin and see what it picked up. It probably won't have found much since we've been keeping our new floor sort of obsessively clean.
