Through the step S1-pretreatment stage, the dirt suction device can pump away dirt particles or left-over sewage in the cleaning roller and the cleaning tank before the cleaning liquid is sprayed into the cleaning roller and the cleaning tank by the water supply device, so that the influence of the dirt on the subsequent process of infiltrating the cleaning roller is avoided, the cleaning roller can be infiltrated by the cleaning liquid quickly, the self-cleaning effect of the cleaning roller is improved, and meanwhile, the water quantity required in the subsequent step S2-water supply stage and the step S3-cleaning stage is reduced.
By arranging the step S2-water supply stage after the step S1-pretreatment stage and setting the step S2-water supply stage as starting the water supply device, the water supply device can spray or spray liquid into the cleaning roller or the cleaning tank, so that the sprayed cleaning liquid can wet the surfaces of the bristles on the cleaning roller, the water supply device can realize the preliminary wetting of the cleaning roller only by using a small amount of cleaning liquid, the cleaning roller can be further wetted in the subsequent step S3-cleaning stage, and the wetting efficiency and the wetting effect of the cleaning roller are improved.
By arranging the step S3-cleaning stage after the step S2-water supply stage and arranging the step S3-cleaning stage as the roller brush motor drives the cleaning roller to rotate, the water supply device continuously sprays or sprays liquid into the cleaning roller or the cleaning tank, so that the sprayed cleaning liquid can further infiltrate the bristles wetting the upper surface of the cleaning roller, and the cleaning liquid can wet and clean the whole bristles and the root of the bristles. Therefore, the cleaning liquid can be used for carrying out layered wetting cleaning on the bristles on the cleaning roller by adopting the mode of setting the step S2-water supply stage and the step S3-cleaning stage step by step, the self-cleaning effect of the cleaning roller is ensured, the consumption of the cleaning liquid and the time required for wetting the cleaning roller are reduced, the sewage can be conveniently and quickly pumped away in the subsequent step S4-sewage suction stage process, and the self-cleaning period of the surface cleaning machine is shortened.

In addition, in the sewage suction process that the cleaning roller repeatedly enters the step S3-cleaning stage and the step S4-sewage suction stage, the sewage suction pipeline can be fully flushed, so that the sewage suction pipeline can be kept in a relatively clean state, and the phenomenon that dirt is accumulated in the sewage suction pipeline is avoided; if the surface cleaning machine judges that the cleaning roller is cleaned, the process goes directly to step S5, i.e., spin-drying stage.
6. By setting the flow value of the water supply device to Q1 in the step S2-water supply phase, the flow value of the water supply device to Q2 in the step S3-washing phase, and setting Q2 to a form of Q1 smaller than 0.5 times, the water supply device can provide a larger flow value and a smaller total amount of water in the step S2-water supply phase, so that the cleaning liquid can quickly fill the water supply passage and the water jetting port, accelerate the jetting of the cleaning liquid, and quickly wet the surfaces of the bristles; and the flow value in the step S3-cleaning stage is set to be in a smaller form, so that the water supply device can uniformly spray the cleaning roller for a longer time, the root parts and the whole of the bristles are thoroughly soaked, the phenomenon that cleaning liquid in the water tank is used up quickly to cause frequent water replenishing and dirt containing barrel cleaning of a user is avoided, and the use experience of the user is improved.

After the water supply device 12 stops spraying water, a small amount of dropping liquid remains in the cleaning tank 21, so that the water consumption in the cleaning stage is reduced, and the subsequent sewage suction device 14 can conveniently and quickly suck sewage;
step S4-soil pick-up stage: the surface cleaning machine 1 starts the soil pick-up motor 13 to make the soil pick-up motor 13 drive the soil pick-up device 14 to act, the soil pick-up device 14 provides the soil pick-up opening 141 with enough suction effect through the soil pick-up pipeline 142, so that the soil pick-up device 14 can suck the liquid on the cleaning roller 11 and convey the soil to the soil containing barrel 15 for storage through the soil pick-up opening 141 and the soil pick-up pipeline 142, wherein the rated rotating speed V1 of the soil pick-up motor 13 is set to 70000 rpm.
