Top-loading refers to a design feature commonly found in appliances like washing machines and refrigerators, where the access point is located on the top. This allows users to load and unload items from above, making it easier to see and reach the contents without bending down. In the context of washing machines, top-loading models often have a lid that opens upward, providing convenient access to the drum. This design is popular for its user-friendly approach, as it can accommodate larger loads and is generally easier for individuals with mobility issues to use.
