The vacuum cleaner electric brush purchased by Mr. Wu will suffer serious hair loss after being installed and used for a period of time, and the sealing effect cannot be achieved.

For vacuum cleaner electric brushes, the problem of hair loss is generally due to insufficient tension of the vacuum cleaner electric brush and the failure of the cut when the brush is cut. Our company specializes in the production of vacuum cleaner electric brushes, equipped with advanced strip brush production equipment. During the production process, we strictly follow the acceptance standards to ensure that the pulling force of each brush produced is> 6kg. In terms of cutting, we use the industry's most advanced 4-punching equipment for cutting to ensure that the cutting surface of the brush is completely tightened to ensure no hair loss. On the same day, we sent some samples of conventional vacuum cleaner electric brush to Mr. Wu.

Two days later, Mr. Wu called and said that their quality department conducted repeated pull tests on the vacuum cleaner electric brush we provided and found that there was no hair loss. Mr. Wu immediately expressed his willingness to cooperate.
