Product review (5 stars): WORTH EVERY PENNY !
We just ordered a new washer and dryer so figured what better time to clean the dryer vent. They have NEVER been cleaned since we moved into the house in 2001. I have about 22 feet of ducting So I also ordered the extension kit. I cleaned from the outside with the dryer running. Each rod is 3 feet and you stop and attach each rod as the previous rods are inserted..I wound using a total of 7 rods so I made it almost to the dryer itself. (The kit comes with a shield you can put on the dryer to prevent the brush from actually going into the dryer..I didn't use it). There's a 90 degree bend about 15 feet in and the rods navigated through it without issue. I was absolutely SHOCKED at how much lint came flying out as I performed the cleaning. You can be sure this is something I will be performing yearly from now on. Be sure to follow the directions carefully..especially the part about setting drill torque and rotation direction...you don't want anything to come apart in the vent. (Gardus will supply you with a rod retrieval tool if needed)
