I use a Kärcher SC3 steam cleaner. It's cheap (~€100) and pretty good. Even the SC2 is decent. I'd like to add a me-too. We bought a Kärcher SC3 to remove old wallpaper when we moved to another apartment (IIRC the price of hiring a steamer for a couple of days made buying one attractive). We use it now to clean our tiled floors, the bathroom, etc. and it has been excellent. The hot steam removes most stains without much effort, it works without detergents, and it is far less work than mopping the floor.
