The path narrows toward the end farthest from the suction opening, increasing airflow speed there and helping carry dust toward the unit. In one embodiment, an opening at the remote end draws in outside air. Another embodiment directs exhaust air from the cleaning device into that opening to further strengthen the airflow.
