When David’s Neato robotic vacuum cleaner stopped working after more than a year, he flipped it over and tried to figure out what was wrong. It was out of warranty, but maybe it was something simple that he could fix himself. Yes, a tension spring was missing, and the vac wouldn’t be able to maneuver properly.

Nah, forget that: Neato Robotics just sent him an entire new vacuum, no questions asked. [More]
