When Your Little Helper Needs Help

iFixit walks through what actually goes wrong with robot vacuums — brush rolls, sensors, batteries, the whole chaotic little life of your floor-crawling companion — and how to fix it yourself instead of tossing it. It's a love letter to keeping your robot running, and a useful reminder that most robovac failures are cheaper to repair than the sticker price of a replacement suggests. Stretchers, this one's basically written for you.
