When I read about this the first thing I thought about was the Mercedes Benz Kompressor. This is a pretty cool vacuum. The non-automated hand-vac sucks up dust all around your house all while compressing it with its new fangled system. The dust is compressed to four times the size of what it would be if it were sucked up by a normal vacuum, making the vacuum able to be more compact while holding more dust. You can pick it up for about $400 USD.
