Tile

Some things I learned along the way about tile:
1. My floor man says you should use water and vinegar to clean tile flooring. Bleach is destructive to the grout.
2. They make a nice sponge mop with a brush included on the head that is nice for cleaning tile. The one I have is the Quickie Rollomop, and I bought mine at CVS when they had their mops on sale. Expect to pay $15-20, depending on the vendor.
3. Sealing tile helps the grout to hold up and not shed "grit" on your feet. You can buy sealer at Lowes or similar stores, all you do is spray it on the floor one time and you're done.
4. If you are doing tile countertops or showers, where it will be exposed to water on a more or less constant basis, they make a special epoxy grout. It's harder to apply because you have to wear gloves and it costs a whole lot more, but in the long run it's well worth it in these high-wear area.
