The development of vacuum cleaners, both the shape and internal filtration system have made great technical progress so far. The cordless vacuum cleaner is equipped with 12 cone cyclone dust separation system, which can achieve up to 99.67% super high dust and gas separation efficiency by air power alone and 0.3 micron bacteria level precision filtration with only 5 deep filtration to discharge clean air through the precision HEPA intercept bacteria, mold, mites, pollen, etc. It means that the process of using a vacuum cleaner can not only do cleaning work, but also can effectively eliminate the problem of fresh air secondary pollution emission. It is worth mentioning that the suction and mopping function is introduced in line with modern cleaning needs, by matching the strong magnetic suction mop with sufficient down pressure to achieve vacuuming and mopping to clean the ground at one time. Besides, it adopts a convenient tankless design to avoid water leakage and other problems, so that consumers can experience the modern cleaning method.
