How often do you mop the floors ?

I usually mop once a week followed by brooming every 2/3 days. My mother-in-law is adamant that i have to broom+mop everyday for a clean home. We live seperately. I have heard similar advices when i ask others too.

Do you all mop everyday? It's sooo time consuming, takes me half a day to clean spotlessly well. And i hate cleaning half-assed especially when i have to user water/liquids.
