I had a yellow Supralite or whatever they call them today.
Its not a very good vacuum or quick pick up machine. The "filter" clogs constantly restricting airflow. They are amazingly noisy. The handle mechanism slowly wears out causing you to no longer use the machine. And the brushroll doesn't really agitate the carpet.
On the plus side, after I retired it from my home, it lasted in my garage until I finally chucked it from dry bearings and a cracked bin. So it is durable and picks up asphalt dust very well. If you clean the filter often then there's almost no smell that comes out of the machine.
I'm not saying you shouldn't acquire the machine. I suppose it can do all right for quick pick up, but it's just so bulky that I typically just ran for a full sized vacuum. Your opinion may vary.
I didn't hate the vacuum... I just think it's better used for someone who needs a garage vacuum or really does think it's quicker to use than a full sized vacuum.
