Abstract
The hand-held tool head assembly comprises a housing connected to a flexible vacuum hose to a source. The housing has an elongated front wall with a plurality of openings defining a suction surface. An intermediate portion of this wall is cut-out and formed with a receiving structure for receiving inserts. A first insert has a front wall portion with openings so that when it is received in the cut-out portion it is flush with the surface openings on either side of the cut-out to provide a continuous elongated cleaning surface. A second insert is arranged to be substituted for the first insert and has a front undulating suction surface defined by transverse fins with channels therebetween, the side walls of the fins, the front tips of the fins and the floors of the channels all having openings communicating with the interior of the tool head to provide suction surfaces for drapery pleats received within the channels. By use of the second insert, the tool head can rapidly be converted to provide a cleaning device for drapery pleats.
