All-in-One robot vacuum cleaner design

Here's an all-in-one robot vacuum cleaner design from Yanko Design. It can operate as a conventional upright vacuum, and the round robotic cleaner can be detached from the main body. Just like a conventional robot vacuum, the autonomous part has no problem vacuuming under the sofa. Moreover, the two separate vacuum cleaner parts can continue to operate independently since they each have a motor. The designers are: In-oh Yoo and Sun-woong Oh from the Metatrend Institute.
