The function principle and scope of use of vacuum cleaners

The main purpose of vacuum cleaners is air flow technology, which replaces sweepers that traditionally can only be operated with cleaning tools. Like dust collectors, they can use storage devices to recover dust and garbage. For cities like the inland north, the autumn and winter seasons are especially dry. The dust on the city's ground is particularly prone to accumulating. A gust of wind or a car driving at a high speed can be really unpleasant.

With it, we can greatly reduce the harm of dust pollution to the human body and reduce the content of inhalable particles in the air, except for the special weather conditions such as dust storms. And in some water-scarce cities, dusting vehicles are used to avoid the dust from the usual sprinklers, because it can be used to clean the ground without using brushes and water, and due to the introduction of the latest from abroad. With technology, there will be no secondary dust. In the idiom of piracy, “I gently drive away and take away all the garbage”.

The application of vacuum cleaners has a wide market. It can be applied to all urban roads, including urban districts, squares, docks, and parking lots. It can be found in some production parks that pollute industrial and mining companies. Dust problems can all be solved. Not only that, but also the trumpet. Stones and falling leaves in autumn can be effectively removed. The efficiency of cleaning is as high as 98%. Unlike an ordinary sprinkler, the machine rusts because the machine is constantly watered, the maintenance cost of the vacuum cleaner is much lower, and there is not so much attention to detail.
