A cleaning device, including a water pumping apparatus, a cleaning area and a work execution mechanism. The water pumping apparatus includes a receiving part and a transitional connecting mechanism. An accommodating space and a water outlet that communicates with the accommodating space are formed in the receiving part, and the water outlet communicates with the cleaning area. The transitional connecting mechanism is in drive connection with the work execution mechanism, and the transitional connecting mechanism may pump water in the accommodating space into the cleaning area under the drive of the work execution mechanism. The cleaning device uses the ready-made work execution mechanism as a power source, and drives a water pumping operation by means of the transitional connecting mechanism without the need for control by means of a control circuit. The apparatus has high structural reliability and low fabrication costs.

A method, a device and a storage medium for determining a degree of contamination of a cleaning element are disclosed. The method includes: obtaining a first characteristic parameter of a target location in a working area collected by a sensing assembly; obtaining a second characteristic parameter of the target location collected by the sensing assembly; determining a degree of contamination of the target location; and determining the degree of contamination of the cleaning element. The present disclosure can solve the problem of waste of cleaning resources or poor cleaning effect of cleaning device when cleaning the cleaning element based on a fixed cleaning cycle. Since the degree of contamination of the cleaning element can be determined, the present disclosure can determine whether the cleaning element needs to be cleaned, thereby improving the accuracy of determining the cleaning timing of the cleaning element.
