This utility model discloses a vacuuming device for a floor scrubber, including a floor scrubber body. A suction tube is connected to the outer wall of the floor scrubber body. A connecting tube is connected to the end of the suction tube away from the floor scrubber body. A suction squeegee is connected to the end of the connecting tube. A processing component is disposed outside the suction squeegee. When cleaning the floor is required, the suction tube is connected to the suction squeegee, and the suction tube is inserted into the connecting tube. The inclined surface of the hook end contacts and presses against the inclined surface of the retaining ring, causing the hook to deflect around the hinge point with the fixed block as the rotation center. The side of the hook away from the inclined surface contacts the side of the retaining ring away from the inclined surface. When the hook and retaining ring are no longer pressed, the hook and retaining ring are engaged under the action of the spring elasticity. The sealing gasket fixedly installed at the end of the suction tube contacts and presses against the inner bottom surface of the connecting tube. Under the restriction of the engagement of the hook and retaining ring, the sealing gasket is compressed, sealing the connection between the suction tube and the connecting tube.
