摘要

The telescopic rod (5) driven by a motor (8) on a support (6) moves a sweeping tool (4) while its bristles (3) clean a chimney's walls (2) from bottom to top and vice versa. If the telescopic rod is stretched out for the whole length of a chimney shaft, the motor turns in the other direction and switches off when it gets there.
