Abstract: A suction attachment for a hair grooming clipper includes a suction head having a vacuum relief port and a flexible sealing lid for covering the port. The relief port communicates between an internal air flow passage in the suction head and the exterior of the suction head. The sealing lid is movable by a user's finger to regulate the degree of relief of the vacuum provided by the port. The suction head has a flow constriction defined in the air flow passage midway between a front inlet and a rear outlet and proximate the location of the relief port such that regulation of vacuum relief occurs at the region of the passage where the air pressure is highest and air velocity is lowest. Also, a hollow tubular extension at one end can be inserted in the relief port when the port is completely open to prevent clogging of the open port by hair entering the port from the exterior of the suction head.
