With furnishing optimized for dust generation (less materials where the dust-shitting microbes live, like material curtains) and daily Roomba runs (plus eventual air filter running in the background) there is very little to dust off of surfaces. If there's little dust on the floor, it doesn't get kicked up and doesn't land on things. Ergo - Roomba makes dusting easier.
Keeping a basic air purifier (i.e. fan strapped to HEPA filter) at low power but constantly on would also help with the dust problem, I believe. There's not going to be much dust on things if it gets sucked out of the air before landing on things.
