Holikme 30 Feet Dryer Vent Cleaner Kit, Flexible Lint Brush with Drill Attachment, Fireplace Chimney Brushes Extends Up to 30 Feet for Easy Cleaning, Use with or Without a Power Drill

We never thought there was much lint collecting inside our 20′ dryer duct. Our dryer seem to keep taking longer and longer to dry clothes which we attributed to it being 8 years old. I even blew out the duct using a gas powered blower which removed some lint (I thought it removed it all).A year later the washer went out (it was a stackable unit) and we bought a new washer/dryer stack. We thought we bought a lemon because there was a ton of condensation coming out of the dryer vent and it was taking forever to dryer.Enter the Dryer Vent Cleaner Kit. I bought this 8 months ago thinking at some point I would clean out the little bit of lint that was in the ducting. The day the new dryer was installed I removed the dryer to access the vent. I inserted the dryer cleaner which pulled out a few large clumps of lint, but then stopped 1/3 of the way through (leaving one of the 1′ connectors twisted – much like some have posted pictures of). I then went to the other end of the line and did the same thing removing more lint, but stopping 1/3 of the way through. I thought “Great, I cleared the vent!”That evening dryer loads were still taking forever to dry (never really drying) and condensation around the vent was off the charts.At this point I realized that I need to run this cleaner through the entire line. Instead of push it through which creates the twisting of the segments and would never go all the way through for me, I decide to pull it through.To do this I had a pull a string through the vent then tape the end of the segments that connects to the drill and pull that through until the brush it at the beginning of the vent. I watched a video by an electrician who showed how to suck a fishing line with a small plastic bag (like a parachute) through the duct. As I used the shop vac on on end the bag fishing line was not coming out, but I was getting a bunch of lint coming out. I went to the other end to try the same thing with the shop vac and got a ton of lint, but not the fishing line bag until suddenly enough lint cleared that the bag and line came through.I used that to pull a strong string through and then attached the end of the string to the drill end of the vent cleaner rod. Once the end was sticking out, I attached the drill, turn it on, and slow started pulling. The result was miraculous. No bent segments, the pulled through seamlessly, and in the process brought out another ton more of lint (a lot of it went due to the ongoing condensation caused by restricted flow).The trick is to set the cleaner so that you can PULL it through no push it through the duct.New dryer is drying flawlessly. I plan to run the cleaner through the duct once every 6 months and use my shop vac once a month to gauge how frequently I need to clean the vent.Amazing results!
