what kind of tile, ceramic or vinyl, etc.? Ceramic can have an old blanket laid on top and then broken up with a hammer. Then finish, as well as removing vinyl tiles(or removing glued carpet for that matter), with a good floor scraper. Don't forget to add the good old fashioned hard labor and elbow grease. Home cheapo and other lumber yards sell good floor scrapers. Post back and them maybe someone else will post back with how they do it differently.
