Smile, you're on Vacucam! LG's Hom-Bot (RoboKing in the US) was zipping around its own special playpen on the stage at the company's IFA booth today, picking up the occasional speck of dust and using its dual cams to spy on bloggers and Germans, while also diligently avoiding a plastic family dog along its ten-square-foot cube of real estate. The bot's Smart ThinQ technology enables it to interact with an Android or iPhone app, which you'll use to watch a live video feed from its built-in cam, send it rolling to a specific point in the house in "Patrol" mode, or adjust settings. You can also log in remotely, assuming your Hom-Bot is powered up and has a WiFi connection. Official US and Euro pricing and availability hasn't been announced yet, but an LG rep suggested we'll see it in the €500-700 range (about $710-995 US). Cameras and interactivity are nice and all, but that's a lot to spend on any vacuum cleaner. Today's trade show sneak peek is probably the closest we'll be getting to this pricey little vac, so roll past the break for some super action footage.
