The invention, which belongs to the engineering detection equipment manufacture field, relates to a wall cleaning apparatus for a borehole television testing hole. The cleaning apparatus comprises a rubber cover, a main cylinder, a connecting seat, a push rod and an inlet connector. The main cylinder is in a cavity cylindrical shape; and water injection holes distributed uniformly are formed in the wall of the main cylinder. The rubber cover in a cone shape is fixedly arranged on the upper end surface of the main cylinder; and the connecting seat is fixedly arranged on the lower end surface of the main cylinder. A water inlet of the inlet connector is formed in the connecting seat. The push rod is arranged on the lower end surface of the connecting seat. Because the water injection holes distributed uniformly are formed in the wall of the main cylinder, water enters the main cylinder through the water inlet; under the water pressure effect, the water in the main cylinder can be used for carrying out 360-degree full-coverage cleaning on hole wall through the water injection holes distributed uniformly. According to the invention, the wall cleaning apparatus has advantages of reasonable design, simple structure, convenient usage, high working efficiency, and good cleaning effect and is suitable for borehole cleaning at various angles, especially for cleaning of a non-sagging hole wall.
