It's not really in great shape of its dirty in the traffic areas.
The stone has been abraded and is holding the soil.
Think about trying to mop a English muffin.
Your floor is an English muffin sorta.
You need not get to aggressive but 220 resins are a good place to start.
We put some high alkaline cleaner in the tank while we cut it.
Then when you have it all cleaned up start bringing it back using a combo of diamonds,diamond impregnated pads and some honing or even polishing compounds used very sparingly just for color .
It hard to blend a floor like that if you don't cut the entire floor.
Don't ever be worried to cut a floor-that's your job!
Sometimes an extractor might help in these situations.
