Need help, stains on floor from rubber

I purchased a portable washing machine a few months ago. It didn't come
with a caster kit (have since ordered one and am waiting for it to be
delivered). It has rubber feet. In the begining I had problems with the
fill hose leaking onto the floor under the machine (solved that problem by
turning the water on & off as needed). After I'd finish washing I'd move
the machine to mop the floor and of course the feet still were wet. Anyway,
I have all these round circles all over the floor. Have tried cleaning with
soap & water. It faded them very slightly. It's very cheap tiles, I think
it's linoleum. Any suggestions other than replacing the tiles?

Follow up on original post...After trying to find an answer on the web, I
think the tiles are actually vinyl.
