This unit works the air so hard that the exhausted air (under the motor) is hot.

  

This unit has 7dust bags of 30 square foot area.  (Some of the bags are off their hooks in the image above.)

This dirt collector tray is metal.

While the image above looks a bit grungy, it is fully functional and a little cleaning and paint is all that would be needed to make it look great.
