The bag features a corrugated structure on the inside. When used, it is filled with water, cleaning agent and soiled textiles. The fastened bag is laid on its side and left for some time for the detergent to have an effect. The operator then takes hold of the topside and presses it towards the ground to execute a cleaning motion, which is repeated as necessary. The clothes are subsequently removed from the bag and rinsed.
