Does the standard floorhead have a little thingy on it where you can switch from hard floor to carpet? I guess it must do but wanted to check. I am going to buy a Miele vacuum cleaner and trying to choose one. Much as I like the idea of having separate, specialised heads for hard floors and carpets, it's just occurred to me that it will probably be irritating to have to switch between heads in rooms where we have hard floors with rugs on!
