Machine for cleaning affiliate floor

I just opened a small affiliate in Belgium (180sq m) and I’m looking for an affordable machine to wash the rubber floors. Currently using a mop and bucket and it takes me a good 4 hours to scrape my way over them and I’m pretty sure they’re not much cleaner for it. Has anyone tried something like the Bissell Power Clean or any other home combo vacuum / washer like that? Would love to invest in something like the Karcher BR 30/4 C but it’s way out of our price range. Thanks for your help!
