Abstract: A rotary chimney brush apparatus includes an elongated push rod which has a selected degree of flexibility, a motor mounted on an outer end of the push rod, and a brush member mounted on a shaft of the motor. The push rod is coiled up into a spool structure which is rotatably mounted on a base frame. Electrical conductors extend along the push rod from a set of batteries and a switch unit to the motor to supply electrical power to the motor to rotate the brush. The push rod and conductors are enclosed in an outer sheath The push rod is extended from the spool to move the rotating brush up through a chimney to clean it. As the brush is lowered through the chimney, the push rod is retracted back into the spool for carrying and storage.
