Just did an 800 sq ft travertine floor that was installed in 1920 and was really dirty. I used Stu's technique and hired a truck mount extractor company to work with me for half a day for $300. Floor came very nice. Some of the big holes remained a little dark but I ended up filling them in when I did the grout repair. Customer was very happy.
Some before and after pics
