Just one of the many differences between men and women. When Dad does the chores:
80% clean is clean (it is a definition).
It's not de-cluttering, its de-crapifying.
Dad takes a mental measurement of the amount of dirt that each room collects in the vacuum's bag/canister.
Dad enjoys the vindication of vacuuming legos and other plastic, hard, sharp, painful-to-find-in-the-middle-of-the-night toys.
