robot vacuum. Unlike it's purple cousin who spends his time looking inwards, this little guy is always looking outward with its three cameras, capturing video and sending it to your smartphone or PC over WiFi. The robot uses sensors to create a
plan of attack map of your home, allowing you to move it around by clicking the filthiest parts. Like a well-trained puppy, the dust buster also responds to voice commands from up to 5 feet away and it doesn't even bark -- only emitting 48dB of sound while sucking up dust. Of course, laziness of this caliber doesn't come cheap, as it costs 899,000 Korean won, or around $840 bones.
