Said to be designed for cleaning lint. EPIC FAILURE. The tube clogs at the slightest fast. The worst is impossible to clean. At least they should have given you a pole to unclog. It cannot be disassembled and is the most disappointing thing I have ever bought from Amazon. I literally threw it as far as I could into the field behind my house. This thing is missing connectors to connect to my Dyson vacuum. I had to glue it together. The manufacturer should be ashamed of this product and stop supplying it immediately.
