Best way to shine floor tiles

[bluedream]

Just had new shiny floor tiles fitted. What is the best way to clean them nice and shiny?? Normal mopping will leave water marks. Are these spinning mop and bucket ones any good?

Microfibre mop and water, do not use any cleaning products on the tiles. After 20 years my tiles still have a shine. A steam mop is ok as well.
