I had two Royal metal uprights before, both from commercial use, one broke it's fan and another had the motor go unbalanced which I ended up throwing away as the result. In my opinion the perfect example of why I don't recommend direct air Royals or any direct air machine for commercial use. That being said, the first picture was a improved Dirt Devil Featherlite. Second one was a improved Dirt Devil Swivel Glide. Third one was a rebranded Dirt Devil EZ Rewind which one of my local stores had when I worked there, in my opinion a good vacuum. Fourth one was a LG made Panasonic copy, also in my opinion a good vacuum. Fifth one was a rebranded Dirt Devil Vision Turbo, I like them for homes but not for commercial use. And I believe the sixth one is the same one as the Dirt Devil commercial I showed earlier, in my opinion perfect for collectibles and something to play around with. I always thought those orange metals looked so similar to the vacuum shown from Mr. Mom
