Plastic type vacs--We do paint them with a broad brush---BUT plastics vary and the way they are molded or formed.The older Sears,newer Tacony,Sebo,Meile,and high end DTD vacuums are made from the higher grades of plastics-and higher quality molding.The cheap Wally World vacs are made from cheaper,thinner,plastics and made from lower quality molding and forming lines.
