Can I use bleach to clean my ceramic tile floor?

A ceramic tile floor is very durable, and will give you many years of service. Generally speaking, all you need to do to clean it is sweep it daily and use a damp mop to wash it. For stubborn dirt or stains, a couple of drops of soap in the mop water will be sufficient. If the tile or grout is white, you can add a bit of bleach to the mop water, to removed yellowing or stains. Bleach is not needed in routine cleaning of ceramic tile, and is actually a bit of overkill.
