Product review (5 stars): Excellent lint cleaner for long duct
I am very satisfied with this product. I had a serious lint clogging problem with my dryer, to the point that the installer of a new dryer refused to connect it. The problem is that the venting duct is going from the basement all the way to the second floor roof. Regular cleaning brushes do not reach that far, so the duct was clogged somewhere up the way, the lint accumulating over years. So, I bought this product, and added the extension kit. I used the included declogging tool and a slow rotating drill. Slowly and surely I penetrated all the way, and then I used the brush. I filled a bag full of lint.
