I do have one of the Hoover hard floor cleaners that I use on my ceramic tile floors. It works pretty good, but I carry a rag along with me and stop and spot clean some of the grout lines (those that aren't getting clean with the cleaner) as I go. It does a good job on the floor, just not all of the grout lines. They make a special cleaning solution for it, but I just use Mr. Clean or something like that. I also have one of those steam cleaners, but it just doesn't seem to get the grout lines very well.
