摘要： A portable blower-vacuum includes a housing having an inlet and an outlet. A motor is disposed within the housing for rotatably driving an impeller to transfer an airflow from the inlet to the outlet. The blower-vacuum also includes an elongated air outlet structure over which an elongated blower tube may be slid for attachment in a blower mode and removed in a vacuum mode. The outlet structure possesses a configuration that improves the ease with which the blower tube may be fitted to the air outlet. The blower-vacuum also includes a cover disposed over the inlet in a blower mode and a skirt adapted to cooperate with the cover and the inlet to substantially reduce or eliminate lateral airflow from entering the inlet from between the cover and the housing.
