Mr. Lu is a vacuum cleaner installation, because his company has cooperated with Aoqun for many years, and he is very familiar with the business of Aoqun. In my spare time, I heard from Mr. Lu that his company’s 1 1/4 vacuum brush attachment often had errors when aligned with the vacuum cleaner, so that their installation efficiency could not be improved.
After hearing this, Aoqun went straight to his installation site and discovered the assembly principle of 1 1/4 vacuum brush attachment. He immediately suggested that Mr. Lu apply to the company's design department for improvement. As a result, the ease of assembly after improvement is very satisfactory.
Two months later, Mr. Lu called and said that because of Aoqun’s professional guidance to him, the 1 1/4 vacuum brush attachment optimization solution he reported was affirmed by the company.
