A cleaning appliance and method for operating a cleaning appliance having a suds container and a rotatable drum, wherein the drum is arranged in the suds container, and wherein an inside of a drum casing of the drum is smooth, apart from a plurality of nubs, for causing the cleaning liquid in the drum to execute a wave motion during a cleaning process. The cleaning appliance has a feed unit and a drive. The method includes supplying a feed signal to the feed unit, wherein the feed signal causes a cleaning liquid to be fed into the suds container until a predetermined target fill level is reached. The target fill level causes the textiles to float inside the drum. The method includes supplying a motion signal to the drive when the target fill level is reached in order to cause a rotational motion of the drum.

A method of operating a washing machine appliance includes filling a wash tub with a wash liquid during a first cycle. The method also includes receiving a pause input after filling the wash tub and before draining the wash tub during the first cycle. In response to the pause input, the first cycle is paused for a pause duration. The method further includes incrementing a pause counter in response to the pause input and storing the pause duration after pausing the first cycle. The method also includes filling the wash tub with a wash liquid during a second cycle after the first cycle and automatically pausing the second cycle after filling the wash tub with the wash liquid during the second cycle, based on the pause counter and the stored pause duration

A method controls a washing machine including a drum rotatably provided in a tub that receives water, at least one nozzle spraying water into the drum, a washing motor rotating the drum, and a circulation pump circulating water within the washing machine. The method includes: controlling a rotation of the drum by operating the washing motor to rotate the drum at a first rotation speed in a first rotation direction, and to maintain a rotation of the drum at the first rotation speed in the first rotation direction so that laundry in the drum maintains contact with an inner circumferential surface of the drum; and controlling a pump speed of the circulation pump by operating a circulation pump motor in the circulation pump to accelerate and decelerate at least once while the washing motor rotates the drum at the first rotation speed in the first rotation direction.

A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A camera assembly is used to monitor articles for washing within the wash basket. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain a reference image and one or more test images, which utilize image recognition to assess turn-over of the articles for washing during a given wash cycle. When turn-over performance is inadequate, a controller may adjust one or more operating parameters of the wash cycle to improve performance. Turn-over performance of the wash cycle is determined to be adequate once the image recognition process fails to find adequate correlation between the reference image and the test image a predetermined number of times.

The invention relates to a method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and a control device, wherein the method comprises a step for detecting when laundry is sliding and/or rolling, comprising, while rotating the drum, sampling a variable related to a torque of the motor or a rotational speed of the drum over a predetermined period of time; and determining whether the laundry is sliding and/or rolling in the drum based on the variable sampled over the period of time.

The invention further relates to a corresponding washing machine.

A detergent activation method for a cleaning appliance having a rotatable non-ribbed drum for holding the textiles) and includes a step of supplying a feed signal to a feed unit of the cleaning appliance. The feed signal causes the cleaning liquid to be fed into a suds container until a predetermined target fill level in the drum is reached. In the supplying step, a motion signal may be supplied to a drive of the cleaning appliance when the target fill level is reached, wherein the motion signal causes a rocking rhythm of the drum. The rocking rhythm defines successive rotational motions of the drum at increasing rotational speeds without a complete revolution of the drum. In the supplying step, a stop signal may be supplied to the drive when a final rotational speed of the rocking rhythm has been reached, to cause the rotational motions of the drum to stop.
