Θα καθαρίσω το μπάνιο αργότερα, αρκεί να βρω πρώτα τη σφουγγαρίστρα και τον κουβά.

Θα καθαρίσω means I will clean.

A few useful points:

• θα is the particle used to form the future.
• καθαρίσω is the verb form built from the perfective stem of καθαρίζω (to clean).

So:

• καθαρίζω = I clean / I am cleaning
• θα καθαρίσω = I will clean

In this sentence, the speaker is talking about doing the action as a single future event: I’ll clean the bathroom later.

This is about aspect, which is very important in Greek.

Greek often distinguishes between:

• imperfective: ongoing, repeated, habitual action
• perfective: a complete, whole action

Here, θα καθαρίσω uses the perfective form, because the speaker means a completed future action: I’ll clean it.

Compare:

• θα καθαρίσω το μπάνιο = I’ll clean the bathroom
• θα καθαρίζω το μπάνιο = I’ll be cleaning the bathroom / I’ll clean the bathroom regularly

So in your sentence, καθαρίσω is the natural choice.

αρκεί να means provided that, as long as, or on condition that.

So this part:

• αρκεί να βρω...
  means
• as long as I find...

It introduces a condition. The speaker will clean the bathroom later, but only if they first find the mop and the bucket.

Because αρκεί να is a fixed structure that is followed by the να form of the verb.

In Modern Greek, να is used before forms that often correspond to what English learners call the subjunctive.

So:

• βρω by itself is not enough here
• Greek says να βρω

That whole phrase means:

• να βρω = that I find / for me to find / I find

In this sentence, the best natural translation is simply if I find or as long as I find.

Again, this is aspect.

• βρίσκω = I find / I am finding (imperfective/basic dictionary form)
• βρω = perfective form, used after να, θα, etc.

Here the meaning is find successfully, as a complete action:

• αρκεί να βρω πρώτα... = as long as I find first...

The speaker is not talking about an ongoing process of searching, but about the result: actually finding the items.

Because Greek usually does not need subject pronouns when the verb ending already shows the subject.

Both:

• καθαρίσω
• βρω

already clearly indicate I.

So Greek often leaves out εγώ unless it is needed for emphasis or contrast.

For example:

• Θα καθαρίσω το μπάνιο = I will clean the bathroom
• Εγώ θα καθαρίσω το μπάνιο = I will clean the bathroom (emphatic)

Because μπάνιο is a neuter noun, and here it is the direct object of the verb.

Its article is:

• το = the (neuter singular)

So:

• το μπάνιο = the bathroom

Also, for many neuter nouns, the nominative and accusative forms are the same, so το μπάνιο looks the same whether it is the subject or the object.

Because Greek articles change according to gender, number, and case.

Here both nouns are direct objects, so they are in the accusative singular.

• η σφουγγαρίστρα = the mop (feminine nominative)
• τη(ν) σφουγγαρίστρα = the mop (feminine accusative)

and

• ο κουβάς = the bucket (masculine nominative)
• τον κουβά = the bucket (masculine accusative)

So the article changes because Greek marks grammatical relationships more visibly than English does.

Both can be correct, depending on style and pronunciation.

The full form is:

• την

But in everyday writing and speech, the final -ν is often dropped before certain consonants, especially in informal usage.

So you may see:

• τη σφουγγαρίστρα

instead of

• την σφουγγαρίστρα

Before some sounds, many speakers and writers prefer to keep the -ν. In modern usage, both spelling practice and pronunciation can vary.

For a learner, the important thing is:

• τη and την are forms of the same article here.

In Greek, it is very normal to repeat the article before each noun:

• τη σφουγγαρίστρα και τον κουβά

This is especially necessary here because the nouns have:

• different genders
• different article forms

You cannot use one article for both, because:

• σφουγγαρίστρα is feminine
• κουβάς is masculine

So each noun gets its own correct article.

They are adverbs.

• αργότερα = later
• πρώτα = first

So:

• Θα καθαρίσω το μπάνιο αργότερα = I’ll clean the bathroom later
• να βρω πρώτα... = to find ... first

They help organize time:

• αργότερα tells you when the cleaning will happen
• πρώτα shows that finding the mop and bucket must happen before that

Not completely. Greek word order is often more flexible than English word order.

This sentence is natural as written:

• Θα καθαρίσω το μπάνιο αργότερα, αρκεί να βρω πρώτα τη σφουγγαρίστρα και τον κουβά.

But some parts can move for emphasis, for example:

• Αργότερα θα καθαρίσω το μπάνιο...
• Αρκεί να βρω πρώτα τη σφουγγαρίστρα και τον κουβά, θα καθαρίσω το μπάνιο αργότερα.

These may sound slightly different in emphasis, but the core meaning stays the same.

So Greek word order is flexible, but not random.

Not with exactly the same meaning.

• αν βρω = if I find
• αρκεί να βρω = as long as I find / provided that I find

Both express a condition, but αρκεί να sounds more like this condition is enough.

Compare:

• Θα καθαρίσω το μπάνιο αν βρω... = I’ll clean the bathroom if I find...
• Θα καθαρίσω το μπάνιο αρκεί να βρω... = I’ll clean the bathroom as long as I find...

The second one emphasizes that finding those items is the key condition.

The dictionary forms are:

• καθαρίζω = to clean
• βρίσκω = to find

The forms in the sentence are not the dictionary forms:

• καθαρίσω comes from καθαρίζω
• βρω comes from βρίσκω

This is very common in Greek, because many verbs use a different stem in the perfective forms.

So learners should get used to pairs like:

• βρίσκω → βρω
• καθαρίζω → καθαρίσω

Not always. μπάνιο can mean different but related things depending on context, such as:

• bath
• bathing
• bathroom

In this sentence, because of καθαρίσω το μπάνιο, it clearly means the bathroom.

So context tells you which English word fits best.

The comma separates the main statement from the conditional part.

Main statement:

• Θα καθαρίσω το μπάνιο αργότερα

Condition:

• αρκεί να βρω πρώτα τη σφουγγαρίστρα και τον κουβά

In English, you might also separate this kind of extra condition with punctuation depending on style. In Greek, the comma here is very natural and helps show the structure of the sentence.
