Abstract (en)

[origin: WO2021197878A1] The invention relates to a method for activating a detergent for a cleaning appliance (100) with a rotatable drum (104) without ribs for receiving textiles (101), having a step of providing a supply signal to a supply unit (106) of the cleaning appliance (100). The supply signal triggers a supply of the cleaning fluid into an outer tub container (102) of the cleaning appliance (100) until a specified target fill level which reaches into the drum (104) is reached. In a signal providing step, a movement signal is provided to a drive (108) of the cleaning appliance (100) when the target fill level is reached, said movement signal triggering a pendular rhythm of the drum (104). The pendular rhythm defines successive rotational movements of the drum (104) with increasing rotational speeds without a complete rotation of the drum (104). In a signal providing step, a stop signal is additionally provided to the drive (108) when the final rotational speed of the pendular rhythm is reached. In the process, the stop signal triggers a stop of the rotational movements of the drum (104).
