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.

A wearer comfort backpack vacuum, comprising:
- a vacuum body including a cannister portion and an adjacent motor compartment, the cannister portion having an initially open interior defined by surrounding sidewalls and an opening to the open interior;
- a harness for supporting the vacuum body on a wearer's back;
- a cover for the opening of the cannister portion of the body;
- a vacuum hose communicating with the cannister interior;
- a vacuum motor located within the motor compartment arranged for pulling air and debris from a surrounding location, through the vacuum hose, in a primary air flow path through the interior of the cannister portion, and out an exhaust outlet to be exhausted back to the surrounding location;
- at least one filter element disposed within the initially open interior of the cannister portion of the body;
- a special air flow opening in the surrounding sidewalls of the cannister portion of the vacuum body which defines a secondary air flow path through the cannister interior;
- whereby air drawn into the interior of the cannister portion of the vacuum body through the secondary air flow path creates a cooling air movement adjacent the wearer's back when the vacuum body is supported on the wearer's back by the harness.
