How do you keep your homes clean?

I've just swept and mopped. Once the floor dries, I could easily go sweep again and turn up more dust and dirt. If I were to mop again, I'm almost certain the water in my bucket would be filthy. It feels like it's never actually clean.

Beyond that, there's dusting, cleaning windows, sinks, countertops, bathrooms, and probably things I don't even consider. How do you all stay on top of these things?
