It is loud and it is a paper bag, but I like the power.  It comes with hepa filter that catches the exhaust, but I am not using it.  I think it will lead to overheated motor.  Some reviews talks about the heat.  Actually the vacuum body and the exhaust air became cooler longer I ran it.  I can't explain it.  Initial start heat or paper bag filling out?  This comes with one piece metal tube - heavy.  It also has air driven brush head.  I could slow down the brush with my fingers.
