Abstract:     This invention relates to a vacuum cleaner attachment for the purpose of simultaneously cleaning a plurality of slats of a Venetian blind and comprises: A molded body 20, a vertical handle 24, a tubular neck 22, having communication with the body and adapted to be connected to a vacuum cleaner hose (not shown), rectangularly shaped fingers 26 which have communication with the body and extend out horizontally from the side of the body opposite the handle, and each opposing finger face having apertures 44 on a longitudinal center axis, rectangularly shaped brush plates 38 having approximately the same lateral dimensions as the finger faces and having apertures 40 in registry with apertures on the opposing finger faces, brush plates slide on and off the finger faces by way of a channel 34 and lip structures 32 and small tabs 48 on the lip structure lock the brush plates in place, bristles 46 will be affixed to the brush plate faces and extend towards each other when locked in place on opposing finger faces. When in use the operator will grip the handle and insert the fingers of the attachment between the open slats of a Venetian blind, thereby simultaneously sandwiching five of the slats with opposing brushes and while extending the fingers lengthwise between the cords of the blind the attachment will loosen and remove the dirt which will then be carried away by air currents through the apertures and passages of the fingers, body and neck.
