This kit is pure rubbish. The vacuum hose attachment is the same circumference as the vacuum hose itself so it doesn’t fit. Like others have said, the hose on it is folded three times which caused kinks in the hose itself. The dryer vent brush did fit into my dryer and I got lint out of there. But because it was wound up in a circle to fit into the box, it was very curved. I tried the dryer vent hose brush from outside of the house and that worked but again, because it is wound up to fit into the box, it was not straight. I return it because the vacuum piece did not fit.
