The invention provides an intelligent permanent magnet floor heating system cleaning machine. A machine body is provided with a water inlet, an air inlet and a pulse water outlet. An electromagnetic valve is further arranged. The electromagnetic valve is connected with a pulse generator. The pulse water outlet is connected with a water outlet pipe. The air inlet is connected with a permanent magnet air compressor. The machine body is further provided with a self-suction water pump connector. The self-suction water pump connector and the water inlet are connected with a water pump through a water inlet pipe. The water pump is connected with a first controller. The water outlet pipe, the water inlet pipe and an air inlet pipe are all provided with check valves and pressure gages used for detecting pressure. The permanent magnet air compressor is used as an air source, the air output amount, muteness, power consumption and durability are all superior to those of a traditional air compressor, a pulse controller is used for setting the impulse frequency, high-pressure gas is input to a pipeline, water flowing through the pipeline can form impulse-type high-pressure water flow and dirt attached to the inner wall of the pipeline can be washed away. The two modes of running water feeding and self-suction water feeding are available. In the self-suction water feeding mode, a cleaning agent can be added into a water supply source for cyclic cleaning, cleaning power is enhanced and water can be saved.
