Product review (5 stars): Excellent Product Does The Job.
Our dryer blew the thermal breaker and stopped running. Ordered the parts and it was recommended that the vents be cleaned to alleviate the overheating condition and avoid a vent fire. Found my kit at Lowe's and purchased it there. All of the parts are very well constructed. Heavy plastic adapters, and well made brush pieces. Rods were flexible enough to bend into a U shape. Used the small long brush to do the duct work inside the dryer. Do NOT use the rounder shorter small brush! Attached it to one rod and carefully worked it into the screen slot. Moved it up and down and back and forth to clean out the slot. Then removed the long brush and attached the short round brush to a rod using the enclosed set screws. Went to the back of the dryer and ran this brush in and out several times twisting by hand. Used a vaccume to suck up the loosened dust and lint. No issues. My vent has one 45 degree turn going in then a straight 14 foot run to the outside. NO VENT SHOULD HAVE A 90 DEGREE TURN!! If your vent has a 90 degree turn it is installed incorrectly and should be reinstalled correctly according to code. With the small short brush still attached to rod one I worked it into the vent opening and pushed it by the first bend. No problem. I pushed the rod in manually while turning slightly as I went by hand. When I had most of the rod in the vent, I added another rod. Worked this into the vent and repeated without incident until all 4 rods were attached and I felt the brush pop out the end of the line. There is a drill attachment included with the kit. Its part of the obstruction cleaner. Leave the C shaped piece off and attach the shaft to your rod end and chuck it in your drill. If you can turn the torque setting down on your drill so if the brush gets hung up it will not damage the tool. Start slowly and work up to a slow to medium speed. Do not run the drill at high speed! So not use a large drill! Do not ever run the drill in reverse!! I attached my DeWalt drill, and turned the torque setting to 3. Starting slowly with all 4 rods attached I gave it power until it started spinning. I moved the brush in an in and out motion while I drew out the rods one by one and removed them as I went. No problems. I had a short 5 foot section of flex pipe to connect from the dryer to the vent. I temporarily connected this and ran the dryer. Checking the vent outlet with a piece of tissue on a stick I had great air flow and a ton of dirt and debris came out of the line. Although it shows that you can run the cleaner brush through the flexible piping, do not attempt to do it. Its not worth the time to attempt to hold the pipe correctly and work the tool. You'll never get all of the lint and debris out of the tons of little creases anyway. for a few bucks, replace the flexible pipe. I replaced my flexible pipe with a new one, and put the dryer back into position ready for a load to dry. Its important to actually read the instructions, they are there for a reason and cover all of the issues buyers have complained about that should not have happened.
