Roomba up vent / duct

Like many others, our Roomba series robot vaccuum cleaner is simply awesome!
Except for the air vent, the standard vent just blows the air straight out, moving around allot of dust especially when in spot cleaning mode.

This replacement duct can be mounted to the existing dust tray by unscrewing the screws on the bottom of the Aerovac bin and replacing the stock duct by this one.

Showing your makes is highly appreciated!
