ABSTRACT:
A device for cleaning chimney flues or like passageways comprises a multiplicity of generally planar strips of flexible, resilient plastic sheet material each having a length several times greater than its width, the strips having their central areas secured together so that their outer end areas extend radially from the centre, the central areas having a mounting for fixing to a flexible cleaning rod. The strips each have a rounded end and are disposed in overlapping but slidable relationship to each other so that their ends define a circle when viewed along the axis of the device. The flexibility of the elements and the fixing and mounting arrangement are such that the device can be pushed through a passageway considerably smaller in diameter than the length of the strips. The strip ends perform a scraping action, and are not substantially deflected sideways.
