Mr. Kong recently purchased a batch of vacuum with brush cleaners, and found that the gloss and resilience of the nylon brushes returned this time were not as good as before.

After learning about Mr. Kong’s feedback, Aoqun asked Mr. Kong to send samples of the vacuum with brush cleaner over to conduct a careful analysis of the material and craftsmanship. It turns out that the vacuum with brush cleaner nylon that Mr. Kong received now has a little nylon content, but the material will have a pungent plastic smell after burning, and the burning smoke is also black.

The taste of genuine pure nylon after burning will be nylon, but not pungent; the outer layer of the flame is yellow, the inner layer is light blue, and the smoke after extinguishing is white. From this, it can be determined that Mr. Kong's purchaser bought inferior products.

Later, Mr. Kong told us that thanks to our timely help in the test and found the problem. It turns out that his batch of vacuum with brush cleaners is to be exported. The customer happens to be very strict with the EU standard test requirements. Not only are they required to provide reports, but they will also receive the vacuum with brush cleaner 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.
