Backpack vacuums are mainly small units that are ideal for commercial cleaning. We offer back vacuums that are available in electric motor driven models and compressed air operated units. Tank sizes range from 2-gallon to 10-gallon and a variety of filtration packages are available. In addition to the backpack vacuums noted here there is a shoulder carry vacuum for bulky debris; the Turbo Voyager. If you have a need for a backpack vacuum please contact us; we have the resources to locate what you need.
