Product review (4 stars): Did a great job
Purchased the vent cleaning system because of the twists and location of our dryer vent duct. Outside and up a wall about 10 feet, I was able to feed the brush and rods thru the vent and down the wall to dryer outlet in laundry room. The rotary action with a drill attached cleaned out more lint than I thought was possible. An incredible amount of lint came out. Glad I made this purchase.
