Nice, never seen one in yellow. Commercial line? The one my parents had in the 90s was similar to this one, but in red, and the motor was pretty well done when I was old enough to use it.
Have a craftsman shop vac that's a beast too. If you put a filter on it and a bag you will notice a descent bump on power. You think it's good now filter it up and bag it you'll find it's even more powerful.
