What does a twin tub washing machine mean? - Shoppers Q and A

A twin tub washing machine is a type of washing machine that has two separate tubs - one for washing clothes and one for spinning them.

The washing tub usually has an agitator or pulsator to mimic hand-washing, while the spinning tub uses centrifugal force to remove excess water from the clothes. They are considered to be more power-efficient than fully automatic washing machines, but they require more manual labor and attention during the washing process.
