According to CrunchGear:
The autonomous cleaning robot can clean corridors and other similar spaces and also is able to move between the floors of the building by using the elevators.
It can detect obstacles of any kind via a built-in laser sensor (a camera is optional). The (nameless) robot communicates with elevators with a light transmission system.
The thing looks cool – bears a similarity to the drawings I saw of the Zappos robots.
I know that the Roomba is a great robot – generally does the job – but even in my house sometimes had to be emptied multiple times before it was able to completely vacuum one room.
This looks like it has sufficient storage space for my dirt.
