I wanted a larger oreck orbiter. I loved that little thing but I only clean residential. It beat the hell out of dragging my 13 inch hawk 175 with the teeny weeny wheels. It can do a great job for agitation without the need of a 175. My hawk was a strip down model because I wanted it to be lighter. The Eco 13 has been great overall. I wouldn't trade it for any of the other models for my use. If someone is looking to break into commercial carpet cleaning this isn't the best choice because it's too light and only 1/2 hp. Only residential carpets less weight is your friend. Less weight is free hp as well. Durability is yet to be determined but so far so good. I have had to replace my bearing assembly after 8 months. I received the new improved bearing at no charge. Even I could fix that. I expect it to be a wear item. Things that shake don't last as long as things that spin smoothly.
