How to reduce the possibility of secondary pollution when using a cordless smart vacuum cleaner?

When using a cordless smart vacuum cleaner, in order to reduce the possibility of secondary pollution, the following specific measures can be taken:
Double precision filtration technology: The V70 vacuum cleaner adopts double precision filtration technology, which enables the vacuum cleaner to effectively intercept dust above 0.3 microns when inhaling air and dust. 0.3 microns is an extremely small size, and the size of many bacteria, viruses and harmful substances is larger than this. Therefore, with a filtration effect of up to 99.99%, almost all harmful substances and dust particles will be intercepted when passing through the vacuum cleaner, thereby greatly reducing the risk of secondary pollution.
Six-fold filtration system: The six-fold filtration system of the V70 vacuum cleaner starts with the dust cup, first capturing larger particles; then, the 304 stainless steel filter and multi-cone further filter out smaller dust; the air inlet and outlet HEPA deeply intercept dust and bacteria; finally, the silencer sponge not only reduces noise, but also plays an auxiliary filtering role. These six filtration systems work together to ensure that the vacuum cleaner can retain as many polluted particles as possible during the vacuuming process, thereby ensuring that the airflow out of the body is clean.
Washable filter element: The washable design of the air inlet HEPA filter element and the air outlet HEPA filter element not only supports the reuse of the filter element, effectively reducing the cost of consumables, but also allows users to maintain its filtration performance by regularly cleaning the filter element. This operation is simple and convenient. Users only need to take out the filter element, rinse it with clean water, and use it again after drying. In this way, even if it is used for a long time, the filtration performance of the V70 vacuum cleaner can be maintained at a high level.
Operation specification: In addition to the hardware design of the vacuum cleaner, the correct use method is also the key to reducing secondary pollution. For example, before using the V70 vacuum cleaner each time, the user should ensure that the dust bag has been cleaned. This is because using the same garbage bag for a long time will cause garbage to accumulate, which is easy to breed bacteria, causing secondary pollution. In addition, when using it, users should also pay attention to the insulation protective layer of the protective wire to prevent damage caused by long-term dragging on the ground. Although these small details may seem insignificant, they can greatly reduce the risk of secondary pollution.
Indoor ventilation: When using the V70 vacuum cleaner, it is recommended that users open windows for ventilation. This can promote indoor air circulation and promptly expel the small amount of harmful substances that may be produced by the vacuum cleaner. At the same time, the inflow of fresh air also helps to keep the indoor air quality fresh. Especially when using a vacuum cleaner to clean carpets, sofas and other places where bacteria are prone to breed, opening windows for ventilation is essential.
In summary, the V70 vacuum cleaner's advanced filtering technology, washable filter element, correct operation, and indoor ventilation can significantly reduce the possibility of secondary contamination when using a vacuum cleaner.
