A Hoover Floormate probably squirts out too much water to be safe for laminate. You also can't use a steam mop. I would get a microfiber mop pad and get it damp with just water. You can probably use 1 part vinegar to 5+ parts water also. I really despise Swiffer wet cloths and other floor cleaning products because they leave a residue. Even Bona for laminate will build up over time since you don't rinse it so if you use a ph-neutral laminate cleaner like Bona only use it occasionally for deep cleaning.
