An apparatus for removing dust from a vent of the type forming an angle with a vent opening and having a vent diameter, comprising: a flexible tubular conduit having a conduit diameter substantially less than said vent diameter for allowing said tubular conduit to be passed through said angle in said vent and an intake opening at one end and an exhaust opening at the opposite end; a flexible shaft located within said flexible tubular conduit and extending substantially between said intake opening and said exhaust opening; a brush coupled to said flexible shaft at approximately said intake opening of said flexible tubular conduit, said brush having a plurality of flexible bristles located externally of said flexible tubular conduit, and having a brush diameter substantially greater than said conduit diameter of said flexible tubular conduit, wherein said brush is adapted in diameter to substantially occlude said vent substantially obstructing the flow of air therethrough; motor means, coupled to said flexible shaft at approximately said exhaust opening of said flexible tubular conduit, for rotating said flexible shaft causing said brush to dislodge said dust from said vent; and vacuum means for entraining said dust dislodged by said brush and drawing said dust from said intake opening of said flexible tubular conduit to said exhaust opening of said flexible tubular conduit.
