I had real wood laminate flooring laid 4 years ago and like an idiot kept on using the same floor mop and bucket as I had done with our crappy plastic laminate. I've realised I'm wrecking the floor as the gaps between the boards are getting darker and some areas of heavy usage look like they might be going mouldy 
I've done a Google search for what I should be using and it's coming back with a microfibre mop. However I have no idea which one to buy! It's my entire downstairs i.e. living room/diner and conservatory. I also have tiled bathroom and kitchen floors in case that makes any difference. Any clues as to which I should go for?
