The attachment further includes a number of teeth extending awayfrom the inlet andoptionally a grating that extends across the conduit to define a number ofaperturescircumscribed by a conduit margin. These apertures are sized and shaped toselectively separatefine particulate debris from a coarser landscaping medium when suction isapplied through theconduit. The teeth project out of one end of the conduit to serve as a rakefor grooming thecoarser medium as the particulate debris is separated from it by suctionapplied through theconduit with a vacuum cleaner.
