A laundry treating apparatus includes a cabinet with first and second cabinet doors. A first washing apparatus processes laundry that is placed through the first cabinet door at the front. A second washing apparatus processes laundry that is placed through the second cabinet door at the top. The second washing apparatus includes: a tub that holds water and has an opening at a top that is accessible through the second opening of the cabinet; a tub cover that covers the top of the tub and defines an inlet through which the tub is accessible; a tub door on the tub cover that opens or closes the inlet of the tub cover separately from the second cabinet door opening or closing the second opening; a drum inside the tub configured to rotate about a vertical shaft; and a first sensor that generates a signal based on the tub door being open.

Disclosed is a washing system capable of detecting a level of contamination of a laundry tub by executing a big data, an artificial intelligence (AI) algorithm and/or a machine learning algorithm in a 5G environment connected for things Internet. The washing system capable of detecting a level of contamination of a laundry tub according to one embodiment of the present disclosure includes a composite sensor for detecting a level of contamination of a laundry tub, a washing machine controller that receives a digital signal from the composite sensor to determine a level of contamination of the laundry tub, and a server communicating with the washing machine. The washing machine controller or the server learns AI model with the training data set through a machine learning algorithm in order to predict a progressing degree of contamination of the laundry tub.

The present invention relates to a clothes treating device comprising: a cabinet forming an external shape; a tub provided inside the cabinet so as to have an inlet one the upper part thereof, and having water stored therein; a drum rotatably provided inside the tub, having a through-hole on the bottom surface thereof, and having clothes accommodated therein; a stirring part rotatably provide in through-hole so as to stir the clothes; a driving part provided on the lower part of the stirring part so as to provide power for rotating the stirring part and/or the drum; and a coupling provided between the stirring part and the driving part so as to be rotated by the power, and provided so as to rotate the stirring part and the drum in different directions or rotate only the stirring part when a water level of the tub is greater than or equal to a certain water level, and to rotate the stirring part and the drum in the same direction when the water level of the tub is less than or equal to the certain water level.
