Capacity: 13 kilograms. This refers to the wash load (how much laundry it can take in one wash).
Twin tub: There are two separate compartments—one for washing, one for spinning-drying. You load into both but after wash you move (or the machine moves) laundry to the spin tub for moisture removal. This design helps in saving time as spin happens separately.
Semi-automatic: You will need to manually manage operations like switching between wash and spin, possibly adding water manually, selecting timers etc. It won’t run completely hands-free like fully automatic front-loaders.
