Exactly the answer I needed. I always clean the filter on my tumble dryer. However, lint accumulates under the filter over time. It has accumulated enough space in the past where I would use 12 inch tweezers to reach it and try to remove as much lint as possible. He never, ever completely removed it. I decided to buy/try this nozzle. Well folks, works like a charm. This lower area is almost as clean as when the dryer was new. I highly recommend them. Just make sure the connection end of the nozzle and your vacuum hose work together.
