  • Wearer comfort backpack vacuum
    Patent number: 9486120
    Abstract: A backpack vacuum has a body made up of an upper cannister and a lower motor compartment. The vacuum body is supported on a wearer's back by a harness. A vacuum motor draws air from an opening in the upper cannister through a primary air flow path out an exhaust outlet from the lower motor compartment. An adjustable air flow opening in the cannister sidewalls creates a secondary air flow path through the vacuum body which creates a cooling air region adjacent the wearer's back in use.
