Here's the OP. I would love to use a steam mop but it scares the bejeezes out of me. We just put in the laminate in October and DH won't be ripping it out and replacing it anytime soon. I thought steam mops could warp the flooring. Have you noticed any ill effects? We have a few scrap pieces in the basement so I could always put together a mock floor and test it on there a few times, but DH would kill me if I messed up our new flooring (more than we wanted to pay and it took DH and FIL a good 50+ man hours to put it in). I don't see how it would leave the floor any more wet than my old Rubbermaid (I guess similar to a Swiffer Wet Jet maybe), but I don't know if it's something specific with the steam that all vendors warn against (we were always told NEVER to use a steam mop).
Re: If you use a steam mop on your laminate
Never use a steam mop on laminate. I use a microfiber mop and sparingly squirt Pledge multi-surface floor cleaner on it while I mop.

I have Shaw laminate floors and according to their website you should not "wet mop" the floors.
