A laundry washing machine contains a rotatable drum (210) configured to hold laundry (240) during washing thereof. The rotatable drum (210), in turn, contains at least one flexible body (215) configured to alter its volume in response to a fluid medium (F) being fed into or extracted out from an interior of the at least one flexible body (215). As a result, the at least one flexible body (215) varies a volume available for washing fluids (W) and the laundry (240) in the rotatable drum (210), so that for example gentle and yet highly efficient kneading washing actions can be performed.

Techniques described herein generally relate to cleaning with ultrasonic energy. An example method includes introducing a cleaning solution into a planar cleaning cavity formed between a first inner surface and a second inner surface of a non-rigid container, directing ultrasonic energy into the cleaning cavity from an array of ultrasonic energy emitters disposed on the first inner surface, and removing the cleaning solution from the cleaning cavity by creating a negative pressure in the cleaning cavity relative to atmospheric pressure, so that the first inner surface and the second inner surface are displaced toward each other.

Washing machine for the washing of laundry such as clothes and textiles, which washing machine has a main part that comprises: an inlet, for supplying washing water, an outlet, for disposal of washing water, a pump, in order to pump the washing water, a connection unit for fluid tight connection of a washing bag to the main part. The washing bag has fluid tight walls and is removably connectable to the connection unit of the main part, wherein the pump is arranged to pump water and air from the washing bag in order to create a certain negative pressure inside it with respect to the surrounding atmospheric pressure and by that emptying it of washing water.

Washing machine (1) for the washing of laundry such as clothes and textiles, which washing machine comprises one or more of the flexible washing compartments, wherein each also comprises one particular washing zone(s), in which particular washing zone, also referred to as a “progressive intensity washing zone”, a flow of washing water typically containing detergents and/or one or more stain remover, is arranged to be oscillating, typically through a stacked layer of laundry or in other words “a stack of layers”, such that progressive washing is obtained essentially of the whole content of the stacked laundry.

A vibration squeeze drum washing machine includes a housing, a barrel, a drum, a machine door, a vibration squeeze device, a turnover mechanism, a mechanical vibrator, a position sensor, a drum motor, a drive device, a water intake valve, a drainage valve, and a control system. The vibration squeeze device is disposed on an inner side of the machine door and is connected to the machine door via the turnover mechanism.
