The working principle of cordless vacuum cleaner is to use the battery to provide power to the motor, drive the motor to rotate, generate negative pressure, and suck in dust and debris. Specifically, the motor of the cordless vacuum cleaner rotates at high speed, sucks in air, and creates a certain vacuum in the dust bucket. The dust enters the dust bag or dust grid in the dust bucket through the brush head accessories and the main suction pipe. The dust is left in the dust bag or the bucket body. The air filtered by the filter enters the motor and then flows out through the motor.
Compared with wired vacuum cleaners, cordless vacuum cleaners are free from the constraints of power cords and are more convenient to use. However, the suction power of cordless vacuum cleaners is generally not as good as that of wired vacuum cleaners. Therefore, a cordless vacuum cleaner needs to achieve "suction power + dust and gas separation" at the most basic level. The importance of other functions is based on these, such as whether it is lightweight, how long the battery life is, the detection function, the number of accessories, etc.
