Granite Floor Cleaner

I really do not like the Bissell, because it leaves streaks everywhere so I'm down by hand and dry everything. What do people who have floors of marble or granite to recommend the best way to clean this type of flooring. With a hard floor cleaner or a mop and bucket, which also involves drying by hand?

I had a great experience with a black granite floor, we installed for a client. Because he was black, it must be cleaned often, the MOP and the soap we used, the weather in Italy, Germany or the U.S. still left steaks. But there is a spray cleaner called revitaliser Stone Tech Professional, which is used in a spray to clean countertops. Combine that with a Swiffer, cleaning the floor was super easy. Just spray a little down and pass the Swiffer, no streaks, quick and easy.
