Abstract

A cleaning device includes a cleaning base and a device body pivotally connected to the cleaning base. The device body further includes: a wastewater tank detachably assembled on one side of the device body, a power source assembled on another side of the device body; a first air duct bending to communicate the wastewater tank to an air inlet of the power source; and a second air duct communicating an air outlet of the power source to an air outlet of the cleaning device. A working airflow, driven by the power source is configured to sequentially flow through the cleaning base, the wastewater tank, the first air duct, the power source the second air duct, and the air outlet of the cleaning device for discharge.
