Abstract: 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.

Abstract: A cleaning appliance and method for operating a cleaning appliance with a rotatable, non-ribbed drum for the pre-treatment and main treatment of textiles. The method comprises a step of supplying a feed signal for feeding a cleaning liquid into a suds container until a predetermined initial fill level is reached. A saturation action causes the textiles to be pre-treated to be saturated with the cleaning liquid. The method includes reading in a fill level signal that represents a fill level of the cleaning liquid, and supplying a further feed signal for feeding the cleaning liquid into the suds container until a target fill level is reached. A motion signal causes a rocking rhythm of the drum for pre-treating the textiles to be pre-treated. After the pre-treatment, an unlocking of a drum door takes place in order to allow additional textiles to be added for a main treatment of the textiles.

Abstract: A method for operating a domestic appliance with a housing, a rotationally movable drum disposed in the housing for receiving laundry, a motor for driving the drum, a control device for controlling the motor, and an evaluation unit. The method, once a program of the domestic appliance has started, includes controlling the motor via the controller such that the drum is driven by the motor and the drum is moved by an angle of less than 90 degrees. Upon attaining the angle the motor is de-energised. The method includes detecting a rotational-speed signal of the drum from when the motor is de-energised over a predetermined first period, and evaluating the detected rotational-speed signals via the evaluation unit by forming a value. The method also includes interrupting the program when the value is greater than a predetermined first threshold value.
