Learn French: Est-ce qu'il fait le ménage le week-end ? - Does he do the housework on the weekend?

Fait is the "he/she/it" form of the irregular verb faire (to do or to make). Since the subject is il (he), the correct form is il fait (he does). For comparison, "I do" or "you do" would be je fais and tu fais.

Is faire le ménage a special expression?

Yes! While faire means "to do" and le ménage refers to the household, putting them together as faire le ménage is the standard French way to say "to do the housework" or "to clean the house". French uses faire for many everyday activities and chores.

Where is the word for "on" in le week-end?

French doesn't use a preposition like "on" for days of the week or the weekend. Simply putting le before a time word indicates a regular habit. So, le week-end translates to "on the weekend" or "on weekends", showing that this is his normal routine.

Why is it qu'il instead of que il in the question phrase?

When the word que is followed by a word starting with a vowel (like il), the e is dropped and replaced with an apostrophe. This makes the words flow together better when spoken. So, the question phrase Est-ce que il must become Est-ce qu'il.
