SWEEPING ROBOT AND CLEANING MECHANISM THEREOF
The disclosure discloses a cleaning robot and a cleaning mechanism thereof. The cleaning robot comprises a shell and a cleaning mechanism. The cleaning mechanism comprises a flexible roller, a motor for driving the flexible roller to rotate, a water squeezing roller, a roller brush, and a sewage collection tank. The sewage collection tank is located above the flexible roller. The water squeezing roller is disposed adjacent to the sewage collection tank. The center of the water squeezing roller is disposed in parallel with the center of the flexible roller, and the surface of the water squeezing roller is pressed against the surface of the flexible roller. The roller brush contacts the flexible roller. When the flexible roller rotates, the water squeezing roller presses sewage in the flexible roller into the sewage collection tank. The cleaning mechanism of the disclosure has strong squeezing capability, can reduce energy consumption, and reduce noise.
