What kind of flooring do I need that can be cleaned easily when an invalid has an accident?

I have an invalid living in my house. He sometimes cannot control his bowels and makes a mess in the floor. I currently have carpet over hardwood floor. I need the carpet to be taken out and want to find some sort of flooring that can be mopped with Clorox or Lysol in water to destroy odor. I would like to avoid any type of flooring that would have to be glued to the hardwood. It appears that all vinyl flooring has to glued down. Does anyone have any idea what I can put over the hardwood that will stand up to some serious cleaning?

1. Use a polyurethane coating, several coats. Or, you could put a waterproofing coat on it, the kind you use on outdoor decks.
2. pergo?
3. Try laminate flooring, it is easy to install by locking the pieces together like a puzzle and it floats(needs no glue). It also cleans like a dream, we just got it and love it. You can get the kind that looks like wood or tile. We have the ceramic tile type and it really looks like tile. GL!
