A vacuum cleaner can absorb decoration dust.
According to the instruction manual of a general vacuum cleaner, there is a type of powder known as chalk ash dust that cannot be suctioned. It is okay to have some decorative dust, but if there is a large amount or prolonged inhalation, it is not advisable. It is possible to suction the small particles of decorative dust that are difficult to clean after decoration. However, when inhaling, it's essential to pay attention to the dust bag. If it's half or more full, stop and clean it. If there's a reduction in suction, it's best to also stop and clean immediately.
To ensure the efficiency and longevity of your vacuum cleaner, it's important to prioritize proper maintenance. This includes ensuring that the vacuum cleaner bag passes through the filter net before reaching the motor, and regularly cleaning the filter net. During cleaning, be thorough and ensure that any blockages are removed. If the suction appears weak, there may be blockages present in the dust bag or hose. Keeping these areas clean will not only improve the efficiency of the vacuum cleaner, but will also extend its lifespan. Remember, not blocking is key to a properly functioning vacuum cleaner.
