Breakdown of Mi hermano también barre la cocina con la escoba.

Why is it mi hermano and not mío hermano or el hermano?

In Spanish you use a possessive adjective before the noun:

So mi goes directly before hermano.

Mío is a possessive pronoun, used mainly after the noun or instead of the noun:

You would not say mío hermano in modern standard Spanish.

Using el hermano would mean the brother in general, without saying whose brother it is. Here you want to say my brother, so you need mi.

Could this sentence also mean my sibling instead of my brother?
