No quiero pasar la aspiradora por la noche porque hace mucho ruido.

Because after querer when you mean to want to do something, Spanish uses an infinitive:

• Quiero dormir = I want to sleep
• Quiero comer = I want to eat
• No quiero pasar la aspiradora = I don’t want to vacuum

So pasar stays in the infinitive, not the conjugated form paso.

Yes, pasar la aspiradora is a very common way to say to vacuum in Spanish.

Literally, it is something like to pass/run the vacuum cleaner. Spanish often uses verbs differently from English in everyday actions.

You may also hear:

• aspirar = to vacuum
• pasar el aspirador / la aspiradora = to run the vacuum cleaner

In Spain, pasar la aspiradora sounds very natural.

Yes. La aspiradora means the vacuum cleaner.

It is a feminine noun, so it takes la:

• la aspiradora
• una aspiradora

In this sentence, Spanish uses the full expression pasar la aspiradora, where the object is the appliance itself.

In Spanish, no normally goes directly before the conjugated verb:

• No quiero = I do not want
• No tengo = I do not have
• No puedo = I cannot

So No quiero pasar la aspiradora... is the standard word order.

Because Spanish often omits subject pronouns when the verb ending already shows who the subject is.

• quiero already tells you it means I want
• so yo is unnecessary unless you want emphasis or contrast

Compare:

• No quiero pasar la aspiradora = normal
• Yo no quiero pasar la aspiradora = more emphatic, like I don’t want to vacuum

Por la noche means at night / in the evening at night-time, depending on context.

Spanish commonly uses:

• por la mañana = in the morning
• por la tarde = in the afternoon / evening
• por la noche = at night / in the evening

This is just the usual fixed expression. It is not normally en la noche in standard Spain Spanish for this meaning.

In this sentence, porque means because.

• porque = because
• por qué = why

Examples:

• No salgo porque llueve. = I’m not going out because it’s raining.
• ¿Por qué no sales? = Why aren’t you going out?

So here, porque hace mucho ruido gives the reason.

Both can work, but they mean slightly different things.

• hace mucho ruido = it makes a lot of noise
• es muy ruidosa = it is very noisy

In your sentence, hace mucho ruido focuses on the noise it produces, which sounds very natural with machines and appliances.

Also, hacer ruido is a very common Spanish expression:

• Los niños hacen mucho ruido
• La lavadora hace ruido
• El coche hace un ruido raro

Because mucho modifies the noun ruido.

• mucho ruido = a lot of noise

But muy modifies adjectives or adverbs:

• muy ruidosa = very noisy
• muy tarde = very late

So:

• hace mucho ruido = correct
• hace muy ruido = incorrect

The implied subject is the thing being discussed: the vacuum cleaner.

So the sentence means:

• I don’t want to vacuum at night because it makes a lot of noise.

Spanish often leaves out subject pronouns like it, especially when the meaning is obvious from context.

Yes. Spanish word order is flexible, and that version is also correct:

• No quiero pasar la aspiradora por la noche...
• Por la noche no quiero pasar la aspiradora...

The second version gives a little more emphasis to at night. The original is the most neutral.

Yes, there can be a difference.

• por la noche = at night, in the evenings/night-time
• de noche = at night, often with a more general sense of when it is dark / during the night

Examples:

• No trabajo por la noche. = I don’t work at night.
• Los gatos ven bien de noche. = Cats see well at night.

In your sentence, por la noche is the most natural choice.

Yes. No quiero pasar la aspiradora por la noche... can refer to:

• this moment: I don’t want to vacuum tonight
• a general preference: I don’t want to vacuum at night

Spanish present tense often covers both present and general meaning. Context tells you which one is intended.

Spanish often does not use an explicit subject pronoun where English does.

English needs:

• because it makes a lot of noise

Spanish usually just says:

• porque hace mucho ruido

The verb form and the context are enough. Here, everyone understands that the vacuum cleaner is what makes the noise.
