Your moving air in a vacuum cleaner, there is no central "vaccum". a series of fans move air, the moving air pushes the dirt until it is caught by a filter medium which the air is small enough to get through but the dirt is not. The air is then expelled from the device.

I guess you could use pistons to move the air as well, but either way your compressing air not pulling air away.
