How to adjust the air volume of the fan in the cleaning process of the electric sweeper? What is the effect of large air volume?

What should we pay attention to when the electric sweeper is used in rainy days? First, buy a fully enclosed electric sweeper, which can protect the driver from the outside weather. Secondly, check whether the purchased electric sweeper motor has waterproof function. If water enters the electrical parts, it will lead to short circuit of the motor and burn out the motor. Also check whether the fan of the electric sweeper can work independently. There must be water on the road in rainy days. If the fan cannot work alone, if the fan continues to work during cleaning, a large amount of water vapor will adhere to the filter element, plus dust, which will kill the filter element and damage the filter element。
