The invention provides an indoor intelligent disinfection robot which comprises a shell, a moving device is arranged at the bottom of the shell, a microprocessor and a plurality of water tanks are arranged in the shell, the moving device is connected with the microprocessor, a plurality of spray heads are arranged on the periphery of the shell and communicated with the water tanks through pipelines respectively, and electric control valves are arranged at the joints of the pipelines and the water tanks. The electric control valve is connected with a microprocessor, a sensing device is arrangedon the shell and connected with the microprocessor, and the microprocessor is connected with a command end. An operation task instruction is sent to the microprocessor through the command end, the microprocessor drives the sensing device to sense the surrounding environment, the sensing device sends sensing information to the microprocessor, and the microprocessor drives the spray head to spray disinfectant while driving the moving device to move. The working load of workers is reduced, the efficiency of the workers is greatly improved, the workers are prevented from being infected, the safety coefficient is high, and meanwhile the indoor intelligent disinfection robot is simple in structure, convenient to operate, low in production cost and suitable for application and popularization.
