A washing machine for the washing of laundry such as clothes and textiles, which washing machine comprises a main part and a washing bag in which the washing of the laundry takes place,
- wherein the main part comprises:
- an inlet, for supplying washing water,
- an outlet, for disposal of the washing water,
- a pump, for pumping air and the washing water, and
- a connection unit for fluid tight connection of the washing bag to the main part,
- wherein the washing bag has fluid tight and flexible inner walls, and a connection part located in an upper part of the washing bag for fluid tight connection to the connection unit of the main part,
- wherein the connection unit of the main part is arranged to lead water from the inlet of the main part to the washing bag,
- wherein the pump is connected to the upper part of the washing bag and arranged to:
- remove the air from the washing bag to compress and soak the laundry in the washing water, and
- remove the washing water from the washing bag following the air removal to create a negative pressure inside the washing bag with respect to the surrounding atmospheric pressure, and
- wherein the negative pressure causes the flexible inner walls of the washing bag to press toward each other, thereby compressing the laundry between the flexible inner walls, wherein the flexible inner walls are provided with concavities and/or convexities.
