Mr Wu's Vacuum Cleaner

An array of chopsticks are controlled to open and close to collect particulate matter from the floor. The chopsticks are mechanically controlled and just before the opening part of their cycle each pair flicks upwards so as to launch captured particulate matter into the attached bin.

Ideal for cleaning up all the rice you'll spill using Mr Dyson's Chop-sticks (link). Does not work on sauce (though it helps if you've had some sauce).
