If your wooden floors are generally in good condition, then simply sweeping or vacuuming with a floor nozzle should be sufficient to keep them clean. You can follow up with a damp mop if necessary. Be careful when washing your wooden floors though, as using too much water can cause the woods protective coating to dissolve, and avoid harsh chemicals at all costs. One natural and gentle cleaning solution that will also help your wooden floors to shine, is ½ cup of vinegar and 2 tablespoons of furniture polish diluted with a gallon of warm water.
