Customers in the United States want to know if Aoqun has suitable samples of soft brush vacuum cleaner for her reference. The customer service staff of Aoqun learned from the customers that they wanted to check the quality of Aoqun first, and they were worried about the phenomenon of hair loss.

After understanding the customer’s concerns, the customer service introduced Aoqun’s quality inspection standards to the guests. Each soft brush vacuum cleaner has a tensile force greater than 6kg, and a tensile test video was sent to the customer so that the customer can intuitively understand Aoqun’s quality. The customer service sent samples that met the customer's size requirements on the same day.

Three days later, the customer replied to the customer service, "I am very satisfied with your samples, and I have conducted a tensile test myself. Indeed, as you said, the tensile force is greater than 6kg, there is no lint at all, and the quality in all aspects exceeds mine. Expected. You are really focusing on each soft brush vacuum cleaner. I will post an official PO to you later."
