Even the smartest robot vacuums can usually only do one thing: Vacuum. That's why we're so intrigued by the LG Hom-Bot Turbo+ . Unlike its competitors, this vacuum doubles as robotic security guard.
Equipped with an on-board camera that can transmit video to your smartphone, the Hom-Bot Turbo+ can get your house clean—and then keep an eye on the place when you're away. We tested both functions in our robot vacuum labs to find out how well they work, and came away impressed.
