Here’s another new, unedited video clip of an actual residential air duct cleaning, this one also by Adam Spano. In this clip, Adam uses a spinning brush to finish off cleaning a main air duct, dislodging the last vestiges of dust and debris clinging to the inner surfaces of the duct. As this dust is knocked loose by the brush, it is drawn away down the duct away from the camera by the powerful air flow induced by the vacuum hookup at the far end.
