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!

Contrary to the negative reviews, this works well but it does require patience and care. Anyone that hates on this tool likely used it ineptly.I was able to clean out a 24 foot run of dryer ducting having 4 right angle bends. It required some patience and care. It was much more effective than the long, narrow and flexible vacuum hose I first tried. Here are a few points.1. ALWAYS run the brush in the righty-tighty/clockwise manner.2. NEVER run the brush in reverse.3. The bush works best with duct turns when the nylon rods are warmer and more pliable.4. Feed in the extenders two sections at a time at most.5. NEVER use the highest drill speed.6. NEVER use the drill in hammer mode.7. Be patient, slowly bring the brush out and in with small increments.8. If possible run the brush twice at least, in a first pass go from in to out and in a second pass go from out to in.9. If you get kinking of the brush extension you are likely trying to feed in too many sections at a time.10. Kinked extensions can be reformed by gentle heating with a heat gun (350F is plenty, more is not better).Be patient. It is possible that the brush can't full traverse some ducts in both directions (in>out, out>in). In my case with a 4 foot run of dryer ducting having 4 right angle bends, I was able to completely pass the brush from in to out but not from out to in. I did not have to warm the brush despite the 50F ambient temps.I did get a kink in one section but that was my fault, I tried to add in more than 2 segments at a time. I repaired the kink with a low temp heat gun setting. With patience, I was able in the end to pass in 16 segments by introducing only one/two more segments at a time. Yes, doing one or two segments at a time makes this slow and tedious but in practice it is the fastest way since slow is smooth and smooth is fast (but you may already know this).Don't worry if you can't get the brush to fully traverse the duct bot in to out or out to in. For me, the brush could not pass through the fourth right angle duct bend when moving out to in but the in to out direction worked.It is certainly possible that very poorly routed ducting will not be passable (say if the duct has any narrow radius u-turns) but I suspect that wont often be the case. If you cant pass the brush in either of in to out or out to in, try using the narrower brush. I did not need to.

I had about 25 feet of vent tube and it was very dirty. I don't think it was the fault of the brush kit - but the clean-out was a failure. It's a 35 year old house and I don't know if the vent tube has ever been cleaned. I'm guessing "No". The brush pulled lots of lint out from both ends of the tube. The lint on the exit side of the line was soaking wet! That created a significant drag on the brush as it rotated in the tubing that I don't think the brush was designed to handle.During the job - the rods kept wrapping up from the torque. I should have stopped there when that started happening. It's a sign that you're exceeding the capacity of this kit. But I kept going. Ultimately - the brush broke off from the rod about half-way into the tube. One of the rod ends failed and spun off. I was never able to get the brush all the way from one end to the other before it broke off - so I just pushed a lot of the lint into a big wad in the middle. It was between floors so I had no access to the tubing without tearing out drywall in the house. I scoped it with 5 meter camera and believe I saw a damaged section of tubing - that was likely the ultimate problem. With the brush stuck that I couldn't get out and the damaged tubing - I ended up abandoning the entire line and just ran new tubing on another route.Again - this isn't the fault of this kit. It has its limitations - and spinning through soaking wet lint on a long line is one of them. I pushed it too hard and paid the price. If you have a long line and find wet lint in your tubing - I'd hire a pro or get steel-braided flexible line on a brush before trying to get through it.
