A semi-automatic washing machine is a type of washing machine that requires manual intervention for certain tasks. It typically has two tubs: one for washing and another for spinning. Users need to fill the washing tub with water, add detergent, and then start the washing cycle. After washing, they must manually transfer the clothes to the spinning tub for drying. These machines are popular in many households due to their affordability and efficiency. They consume less water compared to fully automatic machines and allow users to control the washing process. However, they require more effort and time from the user.
