Advice on how to select a vacuum for a professional cleaning service

I have been in Orlando at the ARCSI Executive Leadership Conference.  One of the vendors there, CleanMax, had a great variety of vacuums and I thought it would be a good chance to shoot a short video explaining some features and things to consider when buying a vacuum for a professional cleaning service. It also ties nicely into my work as part of the Institute for Service Excellence.  We have a whole chapter of our book and 90 minutes of the Home Cleaning Technician class dedicated to tools and equipment and this will give you a preview of some of the information we share in the class.
