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?
Exactly this. You'd be surprised how much dust it can collect. After a week or two in my small home it can easily collect a fistful of dust, and that's just from me alone.
