Woot, you kill me. Ordered this XV-12 robotic vacuum cleaner today for $299. $399 on Amazon.com and tons of good review with few bad ones. This thing is definitely not a Roomba. It reportedly doesn’t just poke around bouncing off of stuff. Plus, you know, lasers.
Model name ambiguity: The XV-11, XV-12 and XV-15 are the same device.
10 February 2012 update: I let it vacuum the house two nights ago. I’m impressed.
