You're looking at one of the newest versions of the LG Hom-Bot Square robotic vacuum (model number: VR6570LVM). It's a square-shaped Roomba competitor that finds its way around your house with the help of built-in cameras.
There are actually two cameras in the Hom-Bot -- one that keeps an eye on the floors and the immediate surroundings, and a second on top that stares up at the ceiling to help map out the overall shape of the room.
The Hom-Bot uses a typical vacuum brushroll to suck up debris. There's also a dry-mopping, Swiffer-like attachment that you can clamp on to help sweep up dust and pet hair from flat surfaces like tile and hardwood.
