A cleaning apparatus for a surface submerged in a liquid includes: an apparatus body; and an automatic rising-sinking structure, where through an operation of the automatic rising-sinking structure, the apparatus body rises or sinks. The cleaning apparatus for the surface submerged in the liquid automatically rises and sinks through the automatic rising-sinking structure, without being manually searched and lifted out of a water surface. The cleaning apparatus for the surface submerged in the liquid can also automatically rises out of the water surface when a filter box is to be cleaned or machine maintenance is required. The cleaning apparatus for the surface submerged in the liquid reduces a manual labor, shortens searching time, and improves a working efficiency.
