M.S.
We have the original Steam Shark for over 5yrs now and absolutely love it! Its been great on tile/grout, hardwood and other non-carpet flooring. At first, we didn't believe it was cleaning and would 'test' it, but it proved itself time and time again. I keep hoping for something to happen to it, so I can justify buying the new one. It dries instantly, faster than any other method of liquid-cleaning. Not only do other cleaners have chemicals, but they leave a residue that attracts and holds dirt. You won't have that with the Steam Shark.
