If it seems that the world of "living room" robotics have moved away from the likes of the Roomba, LG might have a word or two to say about that. Coming to CES 2016 is a trio of new vacuuum cleaners from the consumer electronics maker. And one of them is practically a smart robot. It even looks like a Roomba. What makes this cleaner different is how users can employ augmented reality to control the vacuum and the way it also doubles as a security guard as well.
