Abstract
A device for cleaning a chimney preferably includes a cleaning head having a hub with brush arms extending from the hub, a cable assembly connected to the cleaning head and having a flexible cable surrounded by a casing, with the casing being sized to allow the cable to rotate in the casing without rotating the casing, at least one positioning assembly for holding the cleaning head a desired distance from the interior walls of a chimney, a motor attached to one end of the cable, and a positioning rod effective for pushing said cleaning head and cable assembly up a chimney for a distance of at least eight feet. A camera may be attached to the casing to allow observation and/or recording of the chimney while the cleaning head is working. The device may further include an air knife for dislodging debris when the device is used to sweep a chimney, and/or a vacuum for removing waste dislodged by the device. The motor may be a variable speed motor that is controlled by a foot switch to allow an individual chimney sweep to operate the cable, the rod, and the motor speed simultaneously.
