A washing machine with 7kg load capacity is suitable for a household of 1 to 2 people. With a washing machine with a 7kg capacity, you'll have enough space for your and your partner or roommate's laundry. Do you want a 7kg washing machine that will spin quickly? Choose a washing machine with 1400 or 1600RPM. The higher the speed, the drier the laundry comes out of your drum.
