Perfect for my purposes the Annual furnace cleaning!

Once a year I have my water-bearing stove it clean so fit again for the next season is. Since falling to quite a lot of soot, both in the stovepipe to the chimney as well as between the tubes of the heat exchanger. Regularly I've ruined me my normal vacuum cleaner, and blown with bursting bags also clouds of soot into the environment. Therefore now my attempt with the current ash vacuum.

Plus:
Particulate matter and large Rußbrocken safely filtered out. Bag includes 100% leak-proof and makes a solid impression.
After an hour of work and suck the entire furnace the bucket was full halfway
Then the bucket was dump and simply tapping the bag, in addition I have showered him.
The aluminum intake manifold allows even a little soot scrape without taking damage.

Minus:
The cable could be a little longer.
Quiet the suction is not, but it's just a working machine and for use is the noise in order.

Conclusion: Although the long-term use, of course feht previously. Today, I would buy it again!
