From the first reservoir through the hose composition is fed to a special nozzle, sprayed over their entire surface. In the second tank in the suction mode enters waste liquid. Clean water supply can be adjusted independently.
1. Clean washing solution. 2. Spray. 3. Spraying the cleaning solution. 4. Absorption of dirt.
5. The collected dirt is moved in a special container. 6. The direction of movement of the brush.
Those who are interested in the washing vacuum cleaners, can be recommended to read more about them – he devoted a separate article (link at the bottom of this article). And we continue to talk about the options that need to pay attention when choosing a vacuum cleaner.
The optimum suction power
This characteristic is decisive when comparing similar models. Naturally, it is better to stay at the one in which the suction power is more important. After all, this suggests a more efficient operation of the vacuum cleaner – then the apartment will be cleaned faster and cleaner.
Just do not be confused with the suction power consumption. This is usually indicated on the vacuum cleaner housing large numbers and is calculated in thousands of watts. So, one can often see these values: 1200, 1800, 2000, 1500 Watt.
This information shows how much power does this model. On the power of suction to the body or the fine print, or both, it is not written. Then you need to look into the technical passport of the device and search for information there.
The problem is that so far for vacuum cleaners do not come up with the standard by which would be measured by the suction power. Such as washing or spinning class in washing machines, which has long led the world to a common denominator. Therefore, different manufacturers have reported the suction power in different ways.
For example, some of them began to measure this parameter airwatt. This item comes from the English system of measures and is not standardized worldwide. So another part of manufacturers indicates a suction power in watts.
Usually decent manufacturing companies always indicate two values of this characteristic: the maximum and nominal. This helps the user to choose a vacuum cleaner in the parameters. The thing is that the maximum suction power occurs in the first few minutes after switching on, and the nominal – 5 - 10 minutes.
Well, when these values differ by 14-16 per cent, not more.
If this indicator lies in the range from 300 to 350 watts, the vacuum cleaner will cope with tiles, linoleum and a short-nap carpet. Owners of large apartments, pets or carpet with a long nap, you can consult the model in which the suction power of 350 to 500 watts. A particularly good combination of – low power consumption combined with high suction power.
This means that the model belongs to the upper class.
To remove from the air as much as possible the percentage of particles of dirt and dust, it must be carefully filtered. Some vacuum cleaners are equipped with the elite class ten or twelve filters. Typically, this is just another ploy marketers.
Let us examine more filtration system. When the air together with dust and debris sucked into the vacuum cleaner, it falls into one of three devices: a bag or container aquafiltering. The largest dust particles and settle there, and small continue their journey with the air before reaching the engine filter. It protects the motor from dust.
Air moves further and reaches the output filters.
Most often used at the output of microfilters electrostatic type, S Hepa filters and devices – HEPA filters. The name of the last – is an acronym which stands for «High Efficiency Particutate Air». If we translate this phrase, we get «high efficiency air cleaning».
Microparticles dust that can capture the output filters can have a size of 0.3 micron. Various models of filters may have varying degrees of effectiveness and durability.
HEPA filter – a kind accordion folded material of a special fiber with a fiber diameter of 0.65 to 6.5 micron. Disposable filters made of glass fiber and paper and reusable – of PTFE. Polyacetal articles require periodic flushing – under this condition, you can use them for a long time, as much as, and by the vacuum cleaner. The efficiency of the HEPA filter determines European standard – norm EN 1822.
Further – More details about the models of HEPA type.
One option HEPA filter performance.
Vacuums produced today usually equipped with HEPA filters, or HEPA H 13 H 12 H HEPA 11. Much less is possible to meet the device, which uses HEPA H 10. The number indicated by the end, determines the degree of air purification.
The larger the value, the more effective working filtering system. In this case, the cleaner the value increases. But those who suffer from asthma and allergies, to save on their own health is not worth it.
Experts know how to choose a good vacuum cleaner for such categories of people – This model, where there are HEPA filters H 13 or higher. They not only all the dust (even very small) is removed from the air, but also to tobacco smoke, and pollen.
When buying a vacuum cleaner to keep in mind that the filters for fine purification, not all models are included. Often they need to be purchased separately. On sale there are several types of HEPA filters – and they are reusable and replaceable.
|The name of the filter and marking||Percentage of removed particles,%|
|HEPA H 10||85|
|HEPA H 11||95|
|HEPA H 12||99.5|
|HEPA H 13||99.95|
|HEPA H 14||99,995|
|HEPA (ULPA) H 15||99,9995|
|HEPA (ULPA) H 16||99,99995|
It should also mention the filters S – devices even higher level of purification. Their degree of trapping allergens and fine dust – 99.97 per cent. They can also be replaceable or reusable.
They require washing or replacement only once a year.
Vacuum Control System
In this case we are talking about a system that includes a vacuum cleaner, turns it off and adjusts the suction power. This typically the buttons on the handset or the lever on the control panel or the housing. vacuum control may be electronic or mechanical.
1.mechanical system. The mechanical system - a rotator or a slide switch located on the fixture. With it, the power is regulated. This system has some disadvantages.
When cleaning, changing the power, we have to bend to the body of the instrument and the possibility of its adjustment is limited to a fixed value.
2.Electronic system. Electronic system – rheostat type regulator, which allows to change the power smoothly, just as adjust the volume in the receiver. Located controller or on the housing or on the tube cleaner. In some models, there is still a liquid crystal display which shows the power value, and other operating parameters. In general, use devices with the electronic system is much easier than with a manual.
In addition, they are less energy-intensive.
By the principle of action distinguish the following types of control vacuum cleaners:
- Wire control presupposes wires from the housing to the tube through a hose. The reliability of this method is high enough, but much heavier wire hose of the vacuum cleaner. Work becomes not very comfortable.
- Infrared control is not less reliable than the previous one, but in this case the hose is still easy. The system works in the same way as a conventional remote control.
- Radio Control – One of the best ways. The reliability of its highest. The only problem – stand model with control very expensive.
Some modern vacuum cleaners are equipped with useful function – power in them is automatically adjusted according to the type of surface to be treated. For example, if you have to clean the floor is smooth, clean books or furniture, it is enough suction power of 250 to 300 airwatt. Well, pile coating require increased suction power to the limits of 300-400 airwatt.
suction pipe – what it should be
The design of the vacuum cleaner, this detail is important. Some time ago, I sold a lot of models with plastic pipes, and still there are such devices (but rarely). Not knowing how to choose the right vacuum cleaner, listen to the advice of professionals – they do not recommend to buy devices with a tube made of plastic suction.
If it is made of metal, it will last much longer.
Structurally, the pipe may be solid or collapsible connected two inserted one into the other tubes.
Often found telescopic suction pipe (on the image). They can be separated to the required length, similar to the rod by fixing in this position. This is very convenient, and the most distinguished feature of this «steep» vacuum cleaner models.
