We return the draft to the vacuum cleaner - 4 reasons for poor suction
Check the bag
The first thing you should do is check how full the bag is. If debris has filled more than 2/3 of the capacity, the draft may become weaker or disappear altogether when you vacuum. The paper bag must be replaced with a new one, as it is disposable. If the container is fabric, it can be carefully pulled out and installed back into the guides, but it is better to rinse in clean water and dry.
As a rule, in modern models of technology, the degree of clogging of the garbage bag is displayed on the body. The light indication in the form of a bulb will light green if the container is still empty and red if it is time to replace it.
We clean filters
Moving further in troubleshooting, it is necessary to check the cleanliness of the fine filter (installed in front of the motor) and the HEPA exhaust filter, which is mounted on the back of the case to the plastic grill. As for the first filter, it must either be completely replaced or washed with water and dried, which depends on the versatility of the material. As a rule, the HEPA filter needs to be replaced every 50 hours of operation of the equipment so that the draft of the vacuum cleaner does not disappear at the most inopportune moment. Checked, replaced, and the vacuum cleaner, as before, poorly collects and sucks garbage? We look through the following elements of the suction system.
We recommend that you immediately watch the video, which shows the trick to increase device performance:
By the method of exclusion, we move on and move on to the next possible reason that the vacuum cleaner began to retract poorly - the hose or brushes were damaged. As for the hose, it may not be fully inserted into the housing or damaged as shown in the photo. Bottom line - the vacuum cleaner does not pull or the draft is very weak.
Brushes are checked for contamination. Usually trash such as hair and thin ropes remains on them. You need to remove all contaminants and check whether traction has appeared. You also need to make sure that the brush roller rotates freely and is not worn. Perhaps the bearing simply stuck, as a result of which the brushes interfere with air intake. In general, it should be noted that an uncomfortable nozzle is very often the “culprit” of the weak draft in the vacuum cleaner. Usually, buyers of cheap Chinese equipment are faced with such a moment.
Also try to clean the hose with a wire, perhaps somewhere inside the rubbish interferes with the passage of dust into the bag, which can also be accompanied by the fact that the equipment buzzes or even makes a lot of noise, but does not suck air. You can verify that the cause of poor traction is the hose by disconnecting it and checking the quality of suction by hand at the outlet of the housing. If, in this case, the vacuum cleaner does not suck in, only one possible malfunction remains - the motor.
We repair the engine
Well, the last thing that could be - engine failure. This malfunction can be determined by touching the case with your hand - it heats up very much, which means that something is wrong. In addition to the fact that the motor is very hot and overheating, it can still turn off abruptly. You do not know what is the reason if the vacuum cleaner does not suck in and turn off? Read on why traction was lost and what needs to be done for repairs!
First, you need to remove the decorative protection of the case and use a multimeter to ring all sections of the chain. Typically, the equipment does not work due to a blown fuse. If this is true, replace it with a new one with exactly the same parameters. In the event that there is a break in the winding on one of the coils, it is better to go and choose a new vacuum cleanerbecause buying a motor will be an expensive pleasure. In addition, the contact on one of the wire connections may simply break. Here the repair will not be difficult, especially if you are "friends" with a soldering iron.
If the problem is that the vacuum cleaner does not pull and turns off due to motor brushes that you decide to replace, be careful when connecting them. Incorrect connection of the brushes may cause the vacuum cleaner not to suck in but to blow out dust after repair.
That's all the main causes of malfunctions. In conclusion, I would like to note that if your vacuum cleaner with a water filter does not suck well, you need to act by analogy with ordinary equipment. The only difference is that instead of the dust bag, you need to rinse the aquafilter properly! We hope that now you know what to do in case of any deterioration in traction or its complete absence!
