My second mop died within a year and I will not be replacing it. The machine makes the sound as if it's working but steam no longer comes out, nor does water. It costs way too much for the little it actually does as a mop. I can't speak for its other capabilities as I only used it on floors.
Do not buy - it's one of those products that is too good to be true. It does not last for more than about ten uses.
Bottom Line: No, I would not recommend this to a friend
The same thing happened to me. It's a piece of junk, might as well throw my money out the window.
