When the suction motor 14 is running, the controller 16 is configured to control the suction motor 14 to stop working after receiving the first signal or the second signal. If the suction motor 14 is not in the working state, the suction motor 14 is not started. Since the first accessory 27 has no suction channel, the first accessory 27 is suitable for the steam mode and is used to iron fabrics and the like. If the user wants to use the steam mode, then install the first accessory 27 on the handle 21. Whether the user presses the first control button 241 or the second control button 242, the steam mode can be turned on or switched to.

[0048] When the suction motor 14 is running, the controller 16 is configured to control the water pump 12 and the steam generator 13 of the wet cleaning device 100 to work after receiving the third signal. If the suction motor 14 is not running, then after receiving the third signal, the controller 16 controls the suction motor 14 to generate a suction airflow. After receiving the fourth signal, the controller 16 controls the water pump 12 of the wet cleaning device 100 to work. If the suction motor 14 is not running, then after receiving the fourth signal, the controller 16 controls the suction motor 14 and the water pump 12 to work, and the steam generator 13 does not work, realizing the liquid cleaning mode. When the user needs to use the cleaning mode, just install the second accessory 28 on the handle 21, and then different working modes can be realized by pressing the first control button 241 or the second control button 242.

[0049] By adopting a handle 21 and a cleaning head 2 with multiple accessories, the cost of the cleaning head 2 can be effectively reduced. At the same time, different accessories correspond to different cleaning modes, which can effectively reduce the error rate of user operation. For example, when the first accessory 27 is replaced, no matter which button the user operates, steam can be generated and only steam can be generated. When the second accessory 28 is replaced, it can be switched between two modes according to needs, which is more simple and convenient.
