If you get a robot that automated it you'll feel the difference. Floors get a lot of dust. Especially if you have pets but even without.
I would not personally vacuum daily but having completely automated, vacuuming and mopping, every day has produced wonderful floors. Less work than what we did before too.
There's no germs involved here. Dustin on the floor is dirty socks, and you can peel crumbs and other things under foot under foot. It all goes away if floors are cleaned daily.
