Claim 1
Independent Claim
199 words
A hair vacuum with a stripping clasp comprisIng in combination: a hollow base adapted to receive a vacuum source; an elongated tubular vacuum head attached to said base and in communication with said vacuum source through said base and adapted to receive stripping attachment; said vacuum head having at least one vacuum inlet aperature; a handle attached to said base for manipulating said hair vacuum; an elongated stripping clasp pivotally attached to said base such that said clasp may be moved into close proximity to said vacuum head and said vacuum inlet aperature; a handle attached to said stripping clasp for manipulating said stripping clasp relative to said vacuum head in a scissors-like movement; a lining of a soft material on the inside of said stripping clasp; an elongated tubular stripping attachment for said vacuum head having a plurality vacuum inlet aperatures arranged to communicate with said vacuum head inlet aperature; said aperatures of said elongated tubular attachment fabricated of a soft, flexible material comprising triangular grooves transverse the longitudinal axis of said attachment wherein the cross-sectional profile of said grooves progressively increases from the inner longitudinal extremity of said attachment to the outer longitudinal extremity of said attachment.
