ABSTRACT:
A chimney cleaner designed to be lowered through a chimney from its upper end includes both scrubbing and chopping elements for removing soot, tar, mortar and the like from the chimney walls. The scrubbing elements are adjustable to suit various sizes of chimney flues and are so shaped and attached to a supporting frame as to be urged toward the chimney walls, by the weight of the cleaner as they encounter obstructions on the walls, to enhance their cleaning action.
