كل ما اشغل المكنسة في الصالة، بننضف السجادة اللي تحت الكنبة.

كل ما is a very common way to say whenever or every time that in Egyptian Arabic.

So:

• كل ما اشغل المكنسة... = Whenever I turn on the vacuum...
• It introduces something that happens repeatedly.

It is not literally just all what here; as a fixed expression, it means every time.

After كل ما, Egyptian Arabic very often uses the imperfect without بـ.

So:

• كل ما اشغل = whenever I turn on
• not usually كل ما بشغل in the most natural version of this pattern

A simple way to think about it:

• كل ما + imperfect = the repeated trigger event
• بـ often appears in the main clause to show a habitual result, as in بننضف

So the sentence has a nice natural contrast:

• كل ما اشغل...
• بننضف...

Literally, اشغل المكنسة means I turn on the vacuum cleaner or I operate the vacuum.

In natural English, depending on context, you might translate it as:

• turn on the vacuum
• run the vacuum
• sometimes even start vacuuming

The verb شغّل basically means to تشغيل / to run / to switch on / to operate, depending on what the object is.

Here it clearly means vacuum cleaner, because the verb اشغل suggests something electrical that you turn on.

In Egyptian Arabic:

• مكنسة can be understood as a vacuum in the right context
• If you want to be extra clear, people also say مكنسة كهربا = electric vacuum / vacuum cleaner
• A regular broom is more often مقشة

So in this sentence, المكنسة is best understood as the vacuum cleaner.

الصالة in Egyptian Arabic usually means something like:

• the living room
• the hall
• the sitting area

In many homes, it refers to the main open room or central family sitting space.

So في الصالة is naturally:

• in the living room
• or sometimes in the hall, depending on the house layout

بننضف means we clean or we’re cleaning habitually.

It breaks down like this:

• بـ = a common Egyptian marker for present/habitual actions
• نـ = the prefix for we
• the rest is the verb نضف = clean

So:

• بنضف = I clean
• بننضف = we clean

That double ن is normal here: one comes from the we prefix, and one is part of the verb shape.

Because the subject changes between the two clauses.

The sentence means something like:

• Whenever I turn on the vacuum in the living room, we clean the rug under the couch.

That is completely normal. The speaker is saying:

1. I do the first action
2. then we do the second action

If the speaker wanted both actions to be I, it would be:

• كل ما اشغل المكنسة في الصالة، بنضف السجادة اللي تحت الكنبة.

اللي is the Egyptian Arabic relative word meaning:

• that
• which
• who

In this sentence:

• السجادة اللي تحت الكنبة = the rug that is under the couch

One useful thing about اللي is that it does not change for gender or number. Unlike English, where you might choose between who, which, or that, Egyptian Arabic usually just uses اللي.

It is simply not said in the present tense.

Arabic usually leaves out the present-tense verb to be.

So:

• اللي تحت الكنبة literally = that under the couch
• natural English = that is under the couch

This is very normal in Arabic.

Compare:

• السجادة تحت الكنبة = the rug is under the couch
• no separate word for is

Because the speaker is talking about specific, known things:

• the vacuum
• the living room
• the rug
• the couch

This sounds like a specific home and specific objects in it.

Also, السجادة اللي تحت الكنبة points to one particular rug: the rug under the couch.

If you removed definiteness, the meaning would become less specific. For example:

• سجادة تحت الكنبة = a rug under the couch

But here the sentence is clearly about a specific rug, so السجادة makes sense.

Sometimes you can express a similar idea, but كل ما is the most natural choice here for whenever / every time.

A rough comparison:

• كل ما = whenever / every time that
• لما often means when
• كل مرة = every time, but it usually needs a fuller structure and does not fit as smoothly here

So for repeated events like this sentence, كل ما is the best everyday choice.

A helpful way to see it is:

• كل ما + action 1, action 2

Here:

• كل ما اشغل المكنسة في الصالة = whenever I turn on the vacuum in the living room
• بننضف السجادة اللي تحت الكنبة = we clean the rug that is under the couch

So the full pattern is:

• Whenever X happens, Y happens.

This is a very useful Egyptian Arabic pattern for talking about habits and repeated situations.
