When the device is used for detecting the hidden stains on the surface to be cleaned by using the stain detection device 19, the control panel 21 can be operated to control the stain detection device 19 to be opened so as to search for the hidden stains by using the light spots irradiated to the surface to be cleaned by the stain detection device 19, so that the cleaning efficiency can be improved; after cleaning is completed, the user operates the control panel 21 to control the soil detecting apparatus 19 to be turned off, so as to reduce the power consumption of the battery 15 and prolong the service life of the soil detecting apparatus 19.

In other embodiments, when the cleaning apparatus 1 is a cleaning robot, the stain detection device 19 may be disposed on the head of the cleaning robot to emit detection light to the surface to be cleaned on the front side of the cleaning robot, and when stains on the surface to be cleaned are detected, the cleaning robot may focus on cleaning the area where the stains are located, such as reciprocating cleaning, or the cleaning robot may bypass the area where the stains are located, so as to avoid the cleaning robot from being stained with an odor. The specific execution action of the cleaning robot may be determined according to the actual situation, and is not limited only herein.
