Product review (5 stars): Dryer vent lint remover
This is an excellant product it works as advertised and is easy to use. I used it in a floor to roof standard dryer vent application with 15ft ceilings. The dryer vent tube in my home was was severely compromised with lint. After a few minutes all the lint was removed and the dryer is working much more efficiently and as if new. A brush attaches to threaded and flexible rods which attach to a standard drill. Rotate the drill to the right only and the brush the removes lint very quickly. The rods can bend 90 degrees so no matter the shape of your vent this product should work.
