The roller brush of the vacuum cleaner can loosen the stains through direct contact with the ground and rotational friction. Together with the suction force of the vacuum cleaner, it can remove the stains.
The roller brush is installed at the bottom of the vacuum cleaner and has a large contact area with the ground. When pushing the vacuum cleaner, the roller brush can easily follow the moving direction, turn flexibly, quickly cover the area to be cleaned, and reduce the cleaning time and physical exertion.
When the vacuum cleaner is working, it will suck in a large amount of dust, which contains many tiny particles that are difficult to be detected by the naked eye. The filter can intercept these tiny dust particles with its filter screen structure and discharge clean air.
The motor is the core component of the vacuum cleaner. The filter can intercept the dust before it enters the motor, playing a role in protecting the motor and ensuring that the vacuum cleaner can operate stably.
