LG has launched its latest Hom-Bot robotic vacuum, the Turbo+, and is trying a few techie gimmicks to make it stand out from the latest models by Roomba and Dyson. The main new feature on the Turbo+ is "Home-Joy," a quasi-augmented reality (AR) function that takes advantage of a smartphone app. All you need to do is point your smartphone's camera at a region of the floor you want to clean and the Turbo+ will go to town on it, eliminating the need for any tedious mapping.
