Abstract
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.
