Same dirt come into a small house as a clean one.
This is why, when you live in only part of the house during remodel, it feels dirtier… plus more people are wandering in and out… plus dust and construction dirt.
Conversely when the dust and dirt comes into a larger house…you don’t notice it as quickly…
Just part of what happens when you remodel…
On the side of the coin….I now have a floor dust mop…one per 1000sf of house….the old fashioned model of one house, one mop.. NG… it is tooooo hard to LOCATE the 1 mop in the housel….flood the place!!!!
