I couldnt disagree more. Hardwood floors are NOT so easy to clean. Tile is a much better choice for kitchens, tile with THIN grout lines. Hardwood floors in kitchens are a huge PIA, from my experience. They cannot be scrubbed, because it would damage the floor. Nothing abrasive can be used on them. Hardwood floors are pretty but a royal pain. IMO, anyway.
Cleaning your kitchen doesnt have to be a big deal, if you wipe up messes as soon as they happen. When I cook, I make sure that after I do, all surfaces will be free of spills, splatters, etc., including the floor. You should routinely look inside your fridge and wipe up anything spilled, leaked, etc. Your sink should be cleaned pretty much daily. If you do not have a dishwasher, like me, do your dishes daily and after you do, clean the sink and surrounding counters. For me, keeping the fridge clean is the biggest hassle. I try to wipe up anything that spills but stuff seems to go on in there that I have no control of. LOL! Because I rent, I have a very small fridge, and it gets crowded in there, making it even harder to keep clean.
