ABSTRACT:
A blower attachment for a vacuum cleaner including an attached member disposed over the exhaust air discharge openings that extend around the vacuum cleaner casing. The attached member includes a strap section that extends over and blocks air flow from some of the discharge openings, and a plenum section that extends over and receives the flow of air from the remaining unblocked discharge openings. The plenum section tapers from the inlet port to an air output orifice that may be connected by conventional methods to inflate any of a number of devices that require a high volume of low pressure air. Tabs extending inward from the attached member are received in corresponding discharge openings to secure the attached member to the casing in an aligned position over the discharge openings.
