One of the best things I did was buy a robot vacuum to clean the floors daily - I originally bought a Roomba but really it's a POS, and I ended up getting ones of these that is much better and much cheaper:

You'll be shocked at what a difference managing the dust on the floors will make on the overall dustiness of the space.
One things to note - my spaces are relatively large and I also had the genius idea to put more than one in the same space, but that doesn't work just stick with one, trust me. I can't count how many times you come back and find them both dead because they were trying to use the same charger, etc.
