TECHNICAL FIELD The present disclosure relates to the technical field of operating devices for liquid, and in particular to, a cleaning device and a cleaning device system. BACKGROUND Swimming pool cleaning and maintenance are essential to keep water clean and the swimming pool hygienic. Swimming pool cleaning robots in the market can be classified into three categories. For the first category, the cleaning robot can clean the bottom of the swimming pool only. For the second category, the cleaning robot can clean both the bottom and vertical wall surfaces of the swimming pool, but the cleaning robot should operate under a water surface. For the third category, the cleaning robot constantly floats on the water surface and cleans only the water surface. The three categories of swimming pool cleaning robots have their own characteristics, but these swimming pool cleaning robots cannot effectively adjust positions in a liquid environment and their depth in the liquid environment based on actual needs. As a result, the bottom of the swimming pool, the wall surfaces of the swimming pool, and the water surface cannot be comprehensively cleaned. Consequently, application ranges and operating efficiencies of these cleaning robots are limited. Therefore, there is a need for a moving apparatus used in liquid and a swimming pool cleaning robot which can be flexibly switched between a position on a liquid surface and a position under the liquid surface, to improve the operating efficiency in cleaning water and the application range and reduce cleaning costs.
