When cleaning, first use a vacuum cleaner to suck up the dust on the carpet. After the dust is completely absorbed, dilute the detergent or inject the detergent into the water tank. This is more convenient and faster. Then, spray detergent on all parts of the carpet to ensure that there is detergent in every corner, and then wait for about ten to fifteen minutes for the detergent to interact with the carpet for a period of time. At this time, the stain will be separated from the carpet fiber. Finally, wash with water.
