What is the reason why the suction power of the vacuum cleaner is not strong How to repair the sucti

In fact, this is the inevitable law of all vacuum cleaner products. However, a good vacuum cleaner does not show significant attenuation and can still reach more than 90% of the initial suction power after 3-5 years. However, low-quality vacuum cleaners experience a significant decrease in suction power after a few months of use.

Luckily, the suction decay of most vacuum cleaners can be tracked and restored to peak performance with their own maintenance.

Here are a few reasons that I summarized:

1.Vacuum bags or bins are usually located in wired buckets or horizontal vacuums. There are two types of dust collection bags: disposable and reusable. Even better is a disposable dust bag. This type of vacuum cleaner first sucks the air with dust into the bag, and then the clean air is expelled from the bag. So, if the bag is too full, it will definitely reduce the suction. In this case, don't wait until the bag is full before replacing it, it's best to use two-thirds of the bag.

The dust bin generally refers to a wireless handheld vacuum cleaner, a kind of transparent and visible dust bin. This type of vacuum cleaner is like a garbage collection bin, and when there is too much garbage, it is disposed of. Don't wait until the garbage is too full :

2.There is a problem with the seal: the hose is damaged, the fitting is loose, or the dust box is leaking. The vacuum cleaner uses the principle of vacuum differential pressure to quickly extract air from the inside of the machine, creating a near-vacuum state. The pressure of the gas inside the machine drops sharply, while the outside of the machine is atmospheric. At this point, the negative pressure formed causes the outside air to quickly enter the suction tip and suction tube, completing the continuous gas inhalation action.

So sealing is very important. When some joints and parts in the airflow link of the machine have poor sealing and air leakage, the vacuum pressure difference is greatly reduced and the suction power is reduced. On the handle of some corded vacuum cleaners, there will be a leakage gear, which uses the leakage principle to adjust the suction. Here's why.

Therefore, if the suction power of your vacuum cleaner has decreased significantly, you can also focus on checking the hose fittings and elbows for cracks and damage, whether the fittings are not tightened, whether the dust bin is completely closed, and other similar possible problems.

3.A clogged filter on a vacuum cleaner usually refers to a high-efficiency air filter. The principle of HEPA filters is similar to the masks we wear, and different levels of HEPA filters can intercept different sizes of dust.

The cleanliness of the filter determines whether the airflow is smooth. If the airflow is not smooth, it can also cause the motor to not achieve good results when pumping, resulting in slower pumping speeds, lower vacuum differential pressures, and less suction.

Most vacuum cleaners experience a drop in suction power due to a clogged HEPA filter:

Therefore, it is necessary to check the HEPA filter regularly to see if it gets dirty. Most high-efficiency air filters can be cleaned, but it is not recommended to clean them many times, because the cleaning of high-efficiency air filters cannot be fully restored, and some filters may damage the original structure during the cleaning process, resulting in an increase in the gap between the filters, which will not have a good filtration effect, which is harmful to human health and respiratory health.

4.Inhaling or getting stuck in an obstacle is not a panacea. You can't use it to suck in large pieces of paper, leaves, and tape. Once inhaled, it is easy to get stuck inside tips, linkages, and multi-cone separator structures, which will greatly reduce suction power.

In this case, you need to disassemble and clean it yourself, which is usually not too difficult, and the suction power increases significantly after cleaning.

5.My own vacuum cleaner has been used for more than 2 years without any maintenance or cleaning, but the dirt that has accumulated on it is like this:

While I didn't feel a noticeable drop in suction, in theory, this would definitely have a negative impact on suction. Therefore, I recommend everyone to check and clean it regularly, it won't take too much time.

6.Under normal circumstances, there should be no problem with the motor or circuit. However, the blockage caused by the above reasons is equivalent to increasing the load on the vacuum cleaner. The motor is overloaded for a long time, and the reduction in air flow leads to poor heat dissipation, increasing the possibility of motor damage.

Some users do not pay attention during use, and inhaling moisture will have an impact on the motor and circuit board.

Some electric floor brushes may cause obstacles due to hair entanglement, resulting in uneven roll of the floor brushes and poor vacuum cleaning, which is also the reason for the loss of suction.
