Product review (5 stars): Easy to use
This item makes cleaning out the dryer vent so much easier. Hook up a shop vac on the inside of the house and stand outside as you work the rod with the circling brush throughout the vent liner. Just be aware that what ends up in the shop vac is rather disgusting and be prepared for the smell because it's pretty awful. Despite being gross and smelly, I'm reminded how cleaning out the vent liner is not only a safety issue (because that lint is a fire hazard), your dryer won't work as hard because clothes will dry faster.  A must have for any household. I'm aiming to clean out my vent liner twice as year. This item will make doing that task a whole lot easier.
