According to the owner's manual, you should periodically vacuum or sweep, and as part of regular maintenance, sponge mop, but do not sure dish detergents or vinegar & water as it will dull your floor.
To care for the vinyl, use a damp mop with water and a mild cleaner (doesn't name anything in particular). It does suggest that you can avoid problems of "yellowing", if you do not use cleaners that contain oil based solvents (like lemon oil, Murphy's Oil Soap, etc)
