We recently moved into a house and I have no idea how to properly take care of my hardwood floors. Up until now I've just been sweeping/vacuuming but I need to figure out a proper floor care regimen. Any suggestions?

I have tried to do some research but the problem is I'm not sure what kind of floors we have. The house is about 10 years old and I know the floors are real wood but not sure about if they are sealed etc. I assume that at one point they were but I'm noticing that they aren't nearly as shiny near the entrances and in high traffic areas in the kitchen.

So, once I get them really clean (we have dogs, so constant battle with hair) is there something I can put on them to re-seal or wax them so they have that shiny new look again?
