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

Functions PERFECTLY. Great DIY. No Problems-Used as Directed
Our dryer vents thru metal tubes; behind the dryer; a right angle upward, inside a 10’ tall interior wall-to the attic immediately above; has a second slight angle, and then an upwardly tilted tube to a vent on the roof. Our laundry room gets overly humid/warm sometimes; so I decided to do a vent clean-out, (at least 16 yrs) of potential lint. #1 RULE: Use ONLY the CLOCKWISE /righty-tighty direction w/the drill; even when backing the brush out. #2 SUGGESTION! : Watch the TUTORIAL on U tube -AmplifyDIY “How to clean your dryer vent duct.” His detailed instruction & especially the EXTRA HINTS gave me CONFIDENCE to buy this kit from Amazon. Bristles were the right size and density needed to remove lint and still allow it to fall back down the long tube. They held their shape, were stiff enough to get the job done; but also just soft enough to sweep with some flex/not scraping/damaging the metal tubing interior surface. Flexible, but sturdy extension rods, durable joints/construction.NOTE: I didn’t use a shop vac as in the video; but compensated w/a little clear tent (pics) to minimize dust. I pre-cut my electrical tape into 1.75” lengths; Wiped the connections & my fingers w/alcohol as I went, to remove dust & oils. Tape stayed on and removed easily afterward. I used 14 rods of the 21 rods. Advanced the brush/retreated/advanced again slowly for each rod length. As I got to where I think was the bend at a bend, I could hear the flexible rods “bopping around” a bit; but there was no reduction in operation. As I was reaching the pipe’s slight bend in the attic, and then again near the roof vent; is where noticeably larger amounts of lint dislodged/piled up at the entry point. Used my fingers to gently rake the lint onto the floor. Not knowing when I might reach THE END was a little bit concerning; since our roof is steep and I can’t access that vent if there’s a problem. I went very slow after that second “lint dump” began, and it was obvious when I reached the end since the brush had previously advanced so easily. Linger in that spot for a few extra seconds to break up any posible clumps. Very slowly retreated in advancing/retreating movements to dislodge any remaining bits. Proceed in reverse-order instructions to finish. >TOTAL SUCCESS! Clockwise-only motion (and tape, for peace of mind) kept the connections completely tight! Lots of lint removed. Simple enough, just patience with the a stop/extend/start the drill. Kind of messy; but I needed to sweep behind the dryer anyway! Saved a lot of money. See pics & video. We are only a two person family with no pets for “lint comparison…” and I clean my lint screen before EVERY load.

Project failed – but this is a pretty good kit
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.

I would 100% recommend this item as opposed to paying someone to do it for meIt was easy to use

works as intended but take some effort to taken it apart as all screws are super tight after using

Worked great
