Start of diagnostics - checking the components of the vacuum cleaner
The simplest and most primitive way to test the air suction force is to place your palm on the inlet of the hose (the end where the nozzle is attached), after first turning on the vacuum cleaner. After this, disconnect the hose from the vacuum cleaner and check the suction power by hand without hoses, tubes and nozzles.
If you feel that the power has noticeably increased, look for a kink or crack in the tube or hose; perhaps it’s time to replace these elements.
The Filtero company produces universal hoses and tubes for various brands and models of vacuum cleaners.

Also, large debris could be stuck in the nozzle or, more rarely, in the hose of the vacuum cleaner - try cleaning these parts with a long wire or something similar to catch the dirt and pull it out.
Mechanical damage to the gadget
The source of problems can be minor breakdowns of the device itself. If something goes wrong, you should inspect the vacuum cleaner for:
- Cracks
Every centimeter should be examined - from the body to the accessories.
- Dents on the body
If the device has recently been “flying,” a fall could damage it. So keep an eye on the vacuum cleaner. It is better to replace deformed parts to prevent global breakdown.
- Broken nozzles
Everything wears out, and brushes are no exception. In most cases they will have to be replaced.

Should you buy a new vacuum cleaner bag?
The second most popular reason for loss of power lies in the overfilling of the dust collector of the vacuum cleaner. If your model of vacuum cleaner uses dust bags, and you are sure that you have not changed the bag for a long time, then it is worth replacing the bag. This should only be done when the device is disconnected from the network.
The bag can also become clogged over a short period of time, for example, if pets live in the room being cleaned. Remember that the bag not only collects dust, but also in its pores, the material from which it is made, retains its small fractions, participating in a complex air filtration system. It is impossible to clear dust from pores by shaking or washing.

Ways to solve problems
Diagnostics only helps to find the cause of the vacuum cleaner malfunction. Further actions are aimed at eliminating the breakdown.
Dust collector
Overfilling the dust container with debris is the most common problem of poor suction. For any vacuum cleaner, the bag or container should not be filled more than 80%. As the clogging increases, the draft weakens or disappears completely.
Manufacturers equip expensive models with light indicators for when the dust collector is full. The green light indicates normal operation. When the indicator glows red, the dust bin is full and requires emptying. Cheap vacuum cleaners do not have this function. The dust collector has to be checked after each cleaning.
Fixing the problem of a dirty dust bin is easy. With a cyclone, you simply need to throw the garbage out of the container. A disposable paper bag is only thrown away and a new one is put in its place. The dust collector cannot be used a second time. After use and thorough shaking, the paper walls of the bag weaken. A re-installed disposable dust collector will be torn apart by a strong air flow, and dust will be drawn into the fan.
Housewives always just empty reusable fabric dust collectors. The cleaning method is good, but not effective. A large amount of dust remains between the fibers of the fabric, blocking the free passage of air. After using fabric bags several times, rinse them in clean water.
The dust collector may not be at fault if the power regulator is tightly screwed on. Sometimes turning the wheel can solve the problem of poor suction.
Vacuum cleaner filter test
Typically, a vacuum cleaner has a rear filter (post-motor, in the place where the air leaves the vacuum cleaner) and a pre-motor filter (usually located in the bag compartment). Try, alternately removing one filter or the other, to see if the suction power increases. If you find that the power has increased after removal, it means that the filter is clogged or worn out and must be replaced.

Removing filters should only be done when the vacuum cleaner is turned off.
Features of working with an aqua filter
Vacuum cleaners with such components have an additional HEPA filter, which was mentioned earlier. In devices with similar equipment, it is necessary to check more parts for the presence of accumulated contaminants. Otherwise, a vacuum cleaner with an aqua filter does not work for the same reasons as given above. And faults are eliminated using similar algorithms.
Washing washable and reusable filters
Some filters are “reusable” and their manufacturers allow the filter to be washed under running warm water for cleaning purposes. Read the instructions for your vacuum cleaner carefully. There may be additional information on washing the filter there. You should not wash paper filters, as they may become wet and lose their filtering properties.
If washing the filter does not bring satisfactory results, then most likely the filter is worn out and needs to be replaced.
High-quality HEPA filters can not only visually keep the room clean and protect the internal parts of the vacuum cleaner from wear, but also clean the air from the smallest particles, microbes, and microorganisms. The service life of filters, according to the recommendations of vacuum cleaner manufacturers, is usually 6 months and may be reduced depending on operating conditions.
Engine failure
The final reason why suction may become poor is if the motor fails. You should only undertake inspection and repair of this part of the unit if you have at least some understanding of the structure of electrical appliances. To inspect the engine, you need to remove the cover from the vacuum cleaner body. Using a multimeter, you will have to study the operation of all components of the motor. If a fuse is broken, which is the most common cause of engine failure, it should be replaced with a whole one. If there is a break in the stator, then there is no point in repairing the mechanism. In this case, you will have to replace the entire device completely.
Search for reasons
Diagnostics always helps to determine the cause of poor dust absorption. The procedure can be performed by anyone who knows how to use a screwdriver. However, it may not come to disassembling the vacuum cleaner if the breakdown does not affect the electrical part of the unit.
Often, a superficial diagnosis allows us to identify the following causes of poor absorption:
If these causes are not identified during diagnosis, the problem lies inside the vacuum cleaner. The weakening of the suction force occurs due to a decrease in the power of the electric motor. The reason may be brush wear, contamination of the armature commutator, loose bearings, or the formation of thick dust deposits on the fan impeller. A loss of power sometimes occurs when an electronic unit fails. As a result, the control wheel cannot change the engine speed or it begins to “float”.
To carry out superficial diagnostics, all components are disconnected from the vacuum cleaner. The inspection begins with the working nozzle, then moves on to the telescopic handle and corrugated hose. The components must be free of cracks, holes and other defects. It is important to check the inside for any stuck objects.
The dust collector and filter on the exhaust of the vacuum cleaner are further checked. These two components greatly influence the suction power. The disposable filter is replaced with a new one, and the reusable fabric bag is washed well.
Cyclone vacuum cleaners have an additional foam filter between the motor and the garbage container. The plate becomes heavily clogged with dust and needs to be washed. There is another filter on the exhaust. If it is clogged with dust, the exhaust air becomes obstructed and returns to the fan, reducing the suction power.

What to do to stop noise from appearing
In order to prevent the occurrence of strong noise in heating equipment, it is necessary to take into account the main points when designing:
Modern equipment for regulating flow speed is quite powerful. Even a small wet unit with a low noise level can sufficiently provide comfort in a building with a small area. Correct installation, which was carried out according to the manufacturer's instructions, can greatly improve the performance of the pump.
During installation, it is important to remember that the power unit of models with a “wet” rotor can only be installed horizontally. If you choose a different installation method, there may be problems
To prevent extrusion and damage to small parts inside the pump, it is advisable to attach a filtration device with a deep cleaning function in the area in front of the pump. If the parameters may change, or there is no exact data on the dimensions of the room, the best choice would be models with possible changes in operating modes. The liquid entering the pump should not exceed a temperature of 65 degrees
Therefore, the pump must be installed on the return part of the pipeline.
