After the oil stains or dust particles are dissolved by the washing water, the cleaning assembly can more easily clean them. However, since there is a lot of dirt and sewage mixture after cleaning, it needs to be collected through a sewage collection system. In order to prevent the collected dirt and sewage mixture from polluting the cleaned table surface again, a separate sewage tank needs to be provided to store the dirt and sewage mixture, but the separate sewage tank will occupy a lot of space on the cleaning robot, making the cleaning robot as a whole larger, which is not suitable for relatively narrow table surfaces such as dining tables, windowsills, coffee tables and desks.
