The present disclosure provides a chimney cleaning system. The chimney cleaning system may include a support bracket configured to couple with a chimney pipe. The chimney cleaning system may include a first swivel arm and a second swivel arm. The system may further include a spring that connects to a first swivel arm. The chimney cleaning system may include a gearbox, and a shaft, which may be a horizontal shaft, coupled to the gearbox. The chimney cleaning system may further include a chain having a first end and a second end. The first end connects with the first swivel arm via the spring and the second end connects to the second swivel arm. The actuation of the shaft causes a rotation of the chain about the internal surface of the chimney pipe thereby causing the chain to clean soot, creosote, and other debris from at least a portion of the internal surface of the chimney pipe.
