IRobot has come out with a new, improved Roomba vacuum, and if this extensive review is any indication, it would seem the new model addresses most if not all of the problems earlier models experienced. Bonus: greenie angst over machine gun-toting Roombas conquering our homes.

Our current vacuum cleaner is only about a year old, so we won't be switching any time soon. However, when replacement time comes back around, I'll most likely seriously consider it.
