Vacuum cleaner motors produce noise when running at high speeds. The motor is the core component of the vacuum cleaner. The brushes and electrodes inside the motor will generate friction when reversing, thus generating noise. In addition, the vibration of the motor itself will also produce a certain amount of noise.
When the vacuum cleaner is working, when the airflow passes through the vacuum nozzle, pipes, dust collection bags and other components, noise will also be generated due to the flow and impact of the airflow. Especially when the vacuum cleaner inhales larger particles or encounters a blockage, the airflow is blocked and the noise will be more obvious.
Internal components of the vacuum cleaner, such as fans, roller brushes, etc., will also produce friction and vibration during operation, thereby producing noise.
In order to reduce the noise of vacuum cleaners, manufacturers usually adopt some noise reduction technologies, such as optimizing motor design, using low-noise fans, adding sound insulation materials, etc. However, due to the limitations of the working principle and structural characteristics of vacuum cleaners, noise is still difficult to completely avoid.
For consumers, when purchasing a vacuum cleaner, they can pay attention to the noise level of the product or the noise performance during actual use to choose a relatively quieter product. At the same time, keeping the vacuum cleaner clean and maintained during use to avoid clogging and component wear will also help reduce noise.
