The invention discloses manual-work-free cleaning equipment suitable for an outdoor large led display. The manual-work-free cleaning equipment comprises a machine body, wherein a cleaning cavity is formed in the machine body, a linkage cavity is formed in the front side of the cleaning cavity, and a reset cavity is formed in the left side of the cleaning cavity. According to the cleaning equipment, firstly, a cleaning liquid is added into a storage cavity through a water adding opening, then a plurality of devices are placed and adsorbed on a display screen side by side through a lifting vehicle and an operator, and then a power motor is started in the forward direction so that the devices can be automatically adsorbed on the large screen, then the LED large screen is cleaned, the operation in which the operator needs to fall off from high air to clean the screen is not needed so that the problem that the screen is prone to damage due to manual cleaning can be solved, and the life of the operator is also guaranteed. The cleaning equipment is not only small and flexible, and can also be used in a mode by which multiple equipment cooperate with one another.
