Why Chinese vacuum cleaners are losing that suction power? Talk about the care and maintenance of vacuum cleaners in China

I research and test vacuum cleaner products, and in the usual gatherings of my friends, I would ask consciously or unconsciously whether they have vacuum cleaners at home, what kind of vacuum cleaners they use, and whether they have good or bad experience in using them. A classmate once told me that his family bought more than 1,000 wireless handheld vacuum cleaners, when he first bought it was very good, after more than 1 year, he found that the vacuum cleaner did not work well when he bought it, and the rot is very obvious.

In fact, we are all vacuum cleaners in China to carry out the inevitable development of the law of the product, only a good vacuum cleaner, the decay is not obvious, 3 to 5 years later can still can reach more than 90% of the initial suction, but poor quality vacuum cleaners, in the use of the following a few months after the suction will appear to have obviously declined.

The good news is that most vacuum cleaners have a traceable decay in suction power, and with your own maintenance, you can get back to the best performance possible.

Here are a few reasons I summarize:

1. Dust collection bag or dust bin is full

Dust collection bags can generally be found in Chinese wired bucket or horizontal automatic vacuum cleaners, there are two kinds of disposable and reusable, the better ones are through the disposable dust bag. This traditional vacuum cleaner carries on to inhale air with one dust that will go into the dust bag first and then go out of the dust bag using the clean air. So a dust bag that is too full is definitely going to reduce the suction produced. In this development, don't wait for the dust bag to be full before we change it, it's best to use it to your own two-thirds of the technology is almost enough.

Vacuum cleaners are generally referred to as cordless handheld vacuum cleaners, transparent visual vacuum cleaners. In this type of vacuum cleaner, the trash bin is a garbage collection bin. Don't wait until it's too full to get rid of it.

2.Problems with sealing:The hose is broken, the connector is loose, or the dust bin is leaking.

Vacuum cleaners use the principle of vacuum differential pressure. Air is quickly drawn out of the machine, creating a near vacuum. The gas pressure inside the machine drops dramatically, while outside the machine is atmospheric pressure. The negative pressure generated at this time allows the outside air to quickly enter the suction head and suction tube to complete the long lasting suction effect.

That is why sealing is important. When some joints and parts in the air flow link of the machine are not sealed properly, air will leak. The vacuum differential pressure is greatly reduced and the suction power is reduced. On the handles of some corded vacuum cleaners, the air leakage gear will be designed, that is, the principle of air leakage is utilized to regulate the suction power, and this is the reason.

So we if your vacuum cleaner suction power decreased substantially, you can also check whether there are cracks and breaks in the hose joints and bends by focusing on the work, whether there is no tightening of the bayonet system of the fittings, whether there is a complete closure time of the dust bin and so on and so forth some similar possible problems.

3,Clogged filter

The filter on a vacuum cleaner is usually a HEPA filter. The principle of HEPA filters is similar to that of the masks we wear. Different levels of HEPA filters retain dust of different particle sizes.

The cleanliness of the filter determines whether the airflow is smooth. If the airflow is not smooth, the motor does not achieve good results in extracting air. The pumping becomes slower, the vacuum pressure difference becomes smaller, and the suction power becomes smaller.

Most inhalation droplets are caused by clogged HEPA filters.

Therefore, it is necessary to regularly check the HEPA filter for dirt. Most hepa can be cleaned, but it is not recommended to clean it many times, because the cleaning of hepa filters can not be fully restored, and some filters in the cleaning will destroy the original structure, which will increase the gap between the filters, which in turn can not play a good filtration effect on the human body and respiratory health are harmful.

4, inhaled or stuck in an obstacle

Vacuum cleaners are not foolproof. You can't use them to inhale large pieces of paper, leaves and tape. Once inhaled, they can easily get stuck within the multi-cone separation structure of the suction head and connecting rod.

In this case, it's usually not too difficult to dismantle it yourself, and the suction power will be greatly increased after cleaning.

5, accumulated dirt

I have used my own vacuum cleaner for more than 2 years without any maintenance, and the result of cleaning is as follows.

Although I did not obviously feel the suction power decline, but theoretically there must be a negative impact on suction power, so it is recommended that you regularly check the cleaning, the time will not be too long.

6, motor or circuit failure

Normal development carried out motor and circuit is not a problem but because through the above several main reasons is the result of clogging is equivalent to aggravate the load of the vacuum cleaner motor for a long time overloaded working capacity and the air flow is reduced, thus leading to poor heat dissipation motor will be the cost of increasing the likelihood of damage.

There are also some users do not pay attention to the use of moisture inhalation on the motor and circuit board.

Some electric floor brush due to hair entanglement will also cause obstruction.
