Mmh looks like you had severe problem of water infiltration. honestly you can't get back your floor by only mopping it. You need to abraze the wood with a machine, then put a few layers of nourishing cream for the wood then some taint maybe if you want to get it looking nice then finish with a few protective layers.

I still don't understand people who puts hugly things like cheap linoleum on a perfectly noble and beautiful material like the wood.

Btw your floor is looking cheap too, it's more cigarette paper wood-looking tiles than real wood of real quality.
