The invention discloses a cleaning system for washing machine gimbal salt water injection equipment. The system comprises a salt water tank and a clean water tank, the salt water tank is communicatedwith a water injection hole A and a water injection hole B through two independent salt water injection systems, and the clean water tank is communicated with a drain pipe through two independent clean water injection systems. The system mainly has the advantage that the design is reasonable and ingenious, by means of two relatively independent salt water injection systems and clean water injection systems, uninterrupted work of the washing machine gimbal salt water injection equipment is achieved, and the working efficiency is greatly improved. Meanwhile, the degree of automation is high, nomanual operation is needed, the operation is easy and convenient, and the applicability is high.
