Abstract
A blower vacuum includes a housing having a wall that extends between a first opening and a second opening, and a fan positioned at least partially within the housing and rotatable about a fan axis that extends between the first opening and the second opening. A motor is positioned outside of the housing and is rotatable about a motor axis that is offset from the fan axis. The motor is operable in a first direction to rotate the fan in a first direction to produce an air flow from the first opening to the second opening and operable in a second direction to rotate the fan in a second direction to produce an air flow from the second opening to the first opening.
