摘要： A duct cleaning apparatus and method for cleaning and maintaining the interior of most types of ducts, including chimneys, air conditioning and heating ducts, dryer ducts, vents, plumbing and rain gutter ducts. The apparatus is made up of a flexible shaft connected to a cleaning brush or tool. The flexible shaft can be extended through the use of attached couplings to create an infinitely long cleaning apparatus. The cleaning brushes and tools are configured in a variety of sizes with differing configurations of bristled appendages for specific applications. At least some of the cleaning appendages are partially covered with a sleeve. In one embodiment, cleaning brushes are described for general cleaning and maintenance of ducts. In another embodiment, a tool is used to locate duct blockages. In yet another embodiment, cleaning brushes and tools are described for cleaning and maintaining chimneys, A method is also described for preparing a flexible shaft for use with the cleaning brushes and tools of the present invention.
