If you have a long run of non-flexible vent pipe that stretches from your dryer to the outside of your home, an extension rod of some kind will do the job. You can attach some flexible extensions to your electric drill, which when activated, spins the extension mandrel. With a mop-type brush attached to the end you can bore your way all the way out to where the dryer vent exits your home, ensuring a nice clean run of pipe that’s lint free. Stiff, pole-type rods that telescope out are great if you don’t have to go around any corners. Many of these kits also have various attachments you can buy to change out lightbulbs in sockets high up in cathedral ceilings, clean the blades on large ceiling fans, or clean and squeegee tall windows that are hard to reach.
