I saw the video on youtube when i was searching for air duct cleaning equipment and stumbled onto it, its pretty straightforward, but all in all you can't beat it for the price! it works great for starting out and beats the hell out of paying thosuands of dollars for other machines, i just used my own mytee 1003 and put it in the hose and just slide that in the duct
