This invention discloses a surface cleaning device, belonging to the technical field of cleaning equipment. It includes a body and a floor brush. The floor brush comprises a brush body with a suction port and a clean water tank for supplying liquid, mounted on the brush body. A cleaning component is detachably installed on the front side of the brush body, and the suction port is located at the rear of the cleaning component. A wastewater tank is provided on the body. The lower end of the body is pivotally connected to the rear of the brush body via a hinge assembly. The front end of the clean water tank extends forward and at least covers the cleaning component. The rear end of the clean water tank extends backward and at least partially bypasses the hinge assembly to connect with the brush body. At least a portion of the bottom wall of the clean water tank extends continuously and smoothly from left to right, penetrating the central axis of the brush. This design eliminates the need for a connecting pipe, allowing complete drainage of the liquid in the clean water tank, increasing its capacity while simplifying its internal structure.
