ABSTRACT:
A hand-held implement selectively usuable as a blower or a vacuum. A power-driven impeller moves an airstream through an impeller chamber from an intake port to an outlet port. A pair of coaxial rims surrounds the intake port to form a peripheral groove that can receive the end of a pipe and restrain it from lateral movement. An axial pull device can draw the pipe to hold it in the groove.
