Top-loading machines are a type of washing machine where clothes are loaded from the top. This design allows for easy access to the drum, making it convenient to add or remove laundry without bending down. They typically use an agitator or impeller to move clothes around during the wash cycle. These machines are popular for their simplicity and efficiency. They usually have shorter wash cycles compared to front-loading machines, which can save time. However, they may use more water and energy, depending on the model. Overall, top-loading machines are a practical choice for many households.
