The term 'Laundry Device' can be broken down into two crossword solutions: IRON (4 letters) and IRONER (6 letters). An IRON is a small appliance used to press clothes and remove wrinkles. It is usually heated by electricity or gas and has a flat base that is heated and pressed against fabric. An IRONER, on the other hand, is a larger machine used to press large amounts of laundry at once. It is typically used in commercial settings such as laundromats and dry cleaners.
