Roomba's are cool for a lot of reasons (like creating a 'Web of Roomba' picture!) but they can break down and require some maintenance. My Roomba was diagnosed w/ the "Circle of Death", where the sensors were messed up and it would just spin in a circle over and over... After some research, the fixes were expensive, until I found this one.

The problem is, I didn't realize how crazy the fix was until I got this far into it, as shown in the picture when the thing is in a ton of pieces. I figured I might never get it back together, but after almost an hour, I did end up having it back up and running. The fix worked, and it's like Roomba is all new again.
