Learn German: Die Möbel gehören regelmäßig abgestaubt. - The furniture needs to be dusted regularly.

Using gehören + Past Participle (abgestaubt) is a common alternative to the passive voice used to express necessity. It implies that something needs or ought to be done. It means the exact same thing as Die Möbel müssen regelmäßig abgestaubt werden, but it is shorter and highly common in conversational German.

Does gehören still mean "to belong to" in this context?

No. When gehören is immediately followed by a past participle, it loses its normal meaning of ownership and instead means "needs to be done". If you wanted to say the furniture belongs to someone, you would use a dative pronoun instead of a participle, like Die Möbel gehören mir (The furniture belongs to me).

Why is the verb gehören in the plural form when the English translation says "furniture needs" in the singular?

In English, "furniture" is an uncountable singular noun. In German, Möbel is almost always used in the plural to refer to a collection of furniture. Because the subject is plural, the verb must be plural (gehören). If you want to talk about one specific piece of furniture, you would use the singular das Möbelstück.

Why is the participle abgestaubt instead of geabstaubt?
