Summary: I am a janitor at a large church building. I needed a reliable and durable vacuum. I have only used it a week so I can't attest to it's durability. It has a solid feel to it and was easy to assemble. It works very good doing what it is supposed to do, vacuuming carpet.
Summary: We tried some of the cheaper versions of the Panasonic commercial upright but we always come back to the ultra pro. All parts are available. They seem to hold up well. We use them as the backbone of our multi-building facility vacuum fleet and they seem to do about the best for the money.
Summary: I purchased this vacuum because I wanted something better quality for my house that had an attached hose to do corners and cobwebs. The biggest problem is that the hose is very stiff and each time you use it the vacuum falls over. You have to hold on to the vacuum and hose at the same time.
