oh can i use it on wood floor as it says to ask the wood floor manufaturer. it depends
i wouldn't use any kind of steam/water on my hardwood floors. it will cause 'bubbles' to appear in the hardwood. especially when the water takes a while to dry.
if you want, what you can do is use the steam mop, but then you need to dry it off immediately. just as long as the water doesn't sit on the hardwood.
