Mr. Kong’s company recently purchased a batch of hand vacuum cleaner with brush, and found that the gloss and resilience of the hand vacuum cleaner with brush returned this time are not as good as before.

After learning of Mr. Kong’s feedback, Aoqun asked Mr. Kong to send a sample to conduct a careful analysis of the material and craftsmanship. It turned out that the hand vacuum cleaner with brush that Mr. Kong received now contains a little nylon content, but the material is burned. There will be a pungent plastic smell, and the burning smoke is also black. The authentic pure nylon will taste like nylon after burning, but it will not be pungent; the outer layer of the flame is yellow, the inner layer is light blue, and the smoke after extinguishing is white.

It can be determined that Mr. Kong’s buyer bought a vacuum cleaner with brush of inferior quality. After taking the above test video to Mr. Kong, Aoqun patiently explained to him the benefits of using a high-quality hand vacuum cleaner with brush, and it can pass the latest EU standard SVHC test, while inferior products cannot even pass RoHS 10 items.

Later, Mr. Kong told me when chatting, thanks to our timely help to test and find the problem. It turns out that his batch of hand vacuum cleaner with brush is to be exported. The customer happens to be very strict with the EU standard test requirements. Not only are they required to provide a report, but they will also receive the vacuum cleaner with brush for a second inspection before confirming the receipt and payment. Since then, Mr. Kong has also become one of Aoqun's stable and high-quality customers.
