I've done this vent cleaning for 14years. The Reason Is. First you can have a Fire 🔥 in your Dryer. So make sure that you use air to blow into your lint trap and use vaccum at the same time. Then pull Dyer out, Disconnect Flex that runs between Dryer and wall then vaccum out. Put back together, then turn on Dryer. Go outside to where the Dryer Exhaust, in this video you were watching. And there using a gas compresser with rods reverse blowing. 🤗 And if the Dryer duct that runs about your ceiling to outside can not exhaust properly too, water can collect and will eventually leak threw the ceiling and run into the back of your Dryer and now you have to buy another 🙄 So do get your Dryer Cleaned 😉
@@OnlyBlix hey! I was hourly when I worked for a local company. At that time I was doing residential air duct cleaning and was getting paid $19 an hour. I did dryer vent cleaning and air duct cleaning. I left because of health problems and had a change of profession to do something I wanted to do.
