By robots! That's it--that's the spaceship looking thing over there!
Seriously, though, it's Roomba 530. With 5 cats and a family who isn't all that hot on picking up after their little "accidents", I had to do something, and this is a lot less work on me than the vacuum.
At the moment, it's ensconced in it's charger. Like Chuck Norris, it doesn't sleep.
