A rotatable iron and garment steamer with rotatable iron, has a main body with an electrical heater and is mounted with a housing. A revolver is rotatably connected to the main body and a handle. A position-limiting mechanism for restricting the rotational amplitude and a resilient positioning mechanism for locking the position of rotational angle are both disposed between the main body and the handle. When the relative position of the handle and the main body is locked, the iron can be used as steam iron; after the main body is sleeved with a brush cover, the handle rotates relative to the main body, and the iron can be used as a steam brush.
