I connected the hose directly to the hose end of my 4 gallon Vacmaster. It sucks up most of the drywall dust, and I haven't even tried using a ridged sponge to control dust. My only complaint is that the product description says any 3" x 5" sponge will do. This only applies if you cut the sponge to 4 inches. The description should say 2.5 x 4 inches. In general, this is just a typo.
