Is there a hard floor version of a professional carpet cleaner?

[Libra19752]

We have a stone tile kitchen floor and the grouting is filthy and they are just horrible. I've tried to give them a clean but it just doesn't work, I would like a professional to come and do what professional carpet cleaners can do! Is there such a thing? TIA

Just realised that the numbers make me look like a troll or bot! My original username was Libra1975 and I can't get that to work anymore, hence the 2. I am real.

If you look on google there seem to be a fair few results for companies who do clean stone flooring

I just searched for professional stone floor cleaning company
