Learn Hardcore Norwegian: Hun bruker støvsugeren hver helg. - She uses the vacuum cleaner every weekend.

Because we’re referring to a specific vacuum cleaner she uses regularly, and in Norwegian definite nouns take the suffix -en (for common gender). So støvsugeren is the definite singular form of støvsuger.

Can I use the verb støvsuge instead of bruke støvsugeren?

Yes. The verb støvsuge means “to vacuum,” so you can simply say Hun støvsuger hver helg to express the same idea in a more concise, idiomatic way.

Why is it hver helg and not alle helgene or hver helgene?

Hver always pairs with a singular, indefinite noun and never takes an article. Hver helg literally means “each weekend.” You’ll also see hver dag, hver uke, etc., always with the singular form.

Why is there no preposition like på before hver helg?

In Norwegian, time expressions with hver stand alone without a preposition. You could say på helgene (“on weekends” in a general sense), but with hver you simply say hver helg.

What’s the word order in Hun bruker støvsugeren hver helg? Why does hver helg come at the end?

Norwegian main clauses follow Subject–Verb–Object, and time/adverbial phrases typically follow the object. So you get S (Hun) – V (bruker) – O (støvsugeren) – time (hver helg).

What gender are støvsuger and helg, and what are their articles?

Støvsuger is common (en støvsuger), taking -en in the definite. Helg is feminine, but in Bokmål it also uses en as the indefinite article (en helg), with definite helgen. With hver, however, you never add an article.
