Product review (5 stars): Great tool!
I finally got around to using this dryer vent cleaning system today. It was easy to use and it worked very well! I spent about an hour total cleaning the duct work and area around/under the dryer.
Using the adapter and a small rag I connected my shop vacuum to the wall connection of the vent. My vacuum has a 1.5" hose, smaller than recommended but it worked just fine. I had emptied the vacuum before starting and when I was finished the can was close to half full! Lots of dust and debris came out of the vent pipe! The dryer connects to the wall with a flexible metal duct and the metal pipe in the wall goes straight up through the roof, about 15 feet total run.
I am thinking that the dryer will work much more efficiently now.
This is something that should be done on a yearly basis but I had not done it in the almost ten years we have been in the house. I will be doing this every spring from now on!
