This is arguably the best commercial vacuum I have ever used. I spent about six years doing commercial cleaning and nothing else we used came close. In my last assignment, I had three ladies cleaning an office complex vacuuming for several hours each evening, five days a week. After many problems with another commercial vacuum during the first year, we switched to the Versamatic and found, to our complete satisfaction, that the Versamatic is an excellent and truly versatile performer. I and the ladies especially liked the convenient conversion to wand use for corners, etc.I was so impressed with the machine, that when our church needed to get a new vacuum five or six years ago, I talked them into getting a Versamatic.
