It is just very dirty and has some scratches and black marks etc. 
There is nothing else on it, it is just a marble floor.

Hi 

I always think that you should have a go yourself and save some money.
However marble should be treated with respect when cleaning it. It is
prone to damage if you use harsh chemicals on it.

Try a little test area out of sight. Scrub with a paste of baking soda
bicarbonate of soda), water and lemon juice. Rinse and dry. Baking
soda has an abrasive action without scratching the surface. Ideal for
marble.

Tipking, why would one use a paste of bicarb and lemon juice?  The
citric acid would just neutralise the alkalinity of the bicarb.  Maybe
a bicarb and water paste, or just lemon juice.
