Cleaning A Chimney The Russian Way

That is how it is done in the USA, too.

I was a chimney sweep for one of the founding members of the Chimney Sweep Guild (or, whatever it was called), decades ago.

Rather than a device at the top of the chimney, however, they converted shop-vac-like power suckers, into power blowers...placed the nozzle in the firebox, and blew out everything that was being scraped/scrubbed from the firebox, flue and stack into the environment.

When I would go home at night, I had to take two baths...as the first only got the top layer of soot off my skin.

My nostrils were packed with soot.

This is not the only method of cleaning in the US... There is also the method where the power sucker remains a power sucker...and the soot scrubbed from fireplace & flue is supposed to fall into the vacuum's control... It often misses, and finds its way past the hearth...onto the floor (carpet in many/most cases)...which requires more prep-time (meaning $'s lost to the chimney-sweeping proprietor) and space.
