ABSTRACT:
An apparatus including a cylindrical housing mounting an upper cylindrical housing slidably thereto to vary a spacing between an entrance of the upper cylindrical housing to a series of cutting blades. The cutting blades are mounted to a rotating shaft of an electric motor, with an exhaust conduit positioned between the electric motor and the cutting blades for directing cut hair and debris exteriorly of the housing, with the conduit associated with a source of vacuum, and wherein the conduit includes sliding doors for varying the degree of vacuum directed to the conduit. Alternative configurations include a self-enclosed housing with the vacuum source defined by impeller blades mounted within a lowermost portion of the housing underlying a porous bag with the housing separable to gain access to the porous bag utilizing either a direct drive for the impeller blades, or alternatively a gear drive to circumvent the porous bag.
