It’s no surprise that the home shared by an engineer and a tech journalist is filled with gadgets. We already own a robot, a Roomba, which vacuums our floors every day. So it wasn't a shock to me when my boyfriend showed up with another robotic helper for our home. It's called the Litter Robot II, an automatic self-cleaning litter box. The machine is a big black orb with a hole in the middle. It looks like the Death Star.
