Abstract
A device for cleaning a chimney preferably includes a rod assembly, cleaning arms, fan blades, a camera, and a stabilizing/positioning assembly. The cleaning arms are provided on an assembly that includes a rotatable hub with the cleaning arms extending from the hub. The fan blades may also extend from the hub or they may be provided separately. The camera is continuously rotatable around the longitudinal axis to allow an uninterrupted 360° scan of the chimney. The stabilizing/positioning assembly is effective to position the cleaning assembly hub a pre-selected stabilizing/positioning distance from an interior wall of a chimney while the hub rotates in the chimney. The cleaning and fan hub(s) is driven by a cable surrounded by a casing that allows the cable to rotate in the casing without rotating the casing. Controls allow the operator to control the speed and direction of the cleaning arms and the camera.
