Why do vacuum cleaners lose suction?

When your vacuum cleaner suction is not as good as it used to be, it is expensive to choose to replace it with a new machine. It is very common for the suction to decrease, and many vacuum cleaners face this problem. But there are some ways to fix the suction of the vacuum cleaner, let's find out today.

First of all, we need to understand the reason why the vacuum cleaner loses suction.

Dust container is full

When the container is full, the suction will decrease with it. For those vacuums with low dust collection capacity, it will fill up quickly. For bagless models, you can empty the cup after each sweep. If you wait for it to be full to clean, then its suction will plummet.

Hose is clogged

If there is a large clump of hair in the hose, the machine will definitely lose suction. There are also ways when you are not good at cleaning the blockage. You can choose to find a long stick to shove in one end of the hose and poke the blockage out the other end. If you choose this method, you will need to do it next to the trash can as a cloud of dust may appear.

Something tangled on the brush

If the hair gets tangled on it, it loses its ability to clean, so the suction will decrease with it. It could also be that the floor is too high for the vacuum cleaner. Its brush doesn't work well.

Blocked filter

Blocked filter is one of the reasons for the drop in suction. If there is a lot of dust or debris on the filter, suction will not perform well when it is dirty.

Another possibility is that because the air has escaped from the hose or other places, it is not a confined space anymore. You need to check if the hose is broken or if there are holes in the dust collection container. If you find that the hose is broken, you can fill it with tape. If the rupture area is relatively large, just buy a new one on Amazon.

So how should the suction be restored?

Empty the trash bags first. Avoid too much trash accumulating in them. You also need to change the filters regularly to maintain their suction. The suction will increase significantly after cleaning or replacing. Find and remove the blockage to restore the suction to its original state.
