Pro-Team products have been great for a long time. I made money as a janitor in college and we used all kinds of backpack vacuums. I bought my own when I got my first job out of college in 1998. It still works and I have now bought a rear vacuum for my wife so she can run around the house and touch up high traffic areas. Excellent filtering of the bags, no smell of dust when turning on the rear vacuum cleaner.
