Early in the morning

I woke up at around 530am to prepare myself for the trip to penang, while in the toilet, I heard some scrubbing sound from my neighbour. I ignore the sound initially but when it persist, I then realized that the sound was actually produce by someone doing laundry by hand.
I asked myself who now still wash their clothing by hand, aren't all of us in Singapore already own a washing machine? And why wash so early in the morning?
I began to wonder if it is a domestic helper that is doing this tiring job?
