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!
