Dust collector

The type of dust collector provided in the design of the vacuum cleaner.

Nowadays, there are three main types of dust collectors — a regular bag, a cyclone system and an aquafilter. Also, in some vacuum cleaners (in particular, industrial and fireplace models — see "Product type") dust collectors in the form of rigid containers (tanks) can be used without additional equipment. For such models, the type of dust collector in our catalogue is not specified. As for the three main types, here are their features:

— Bag. A dust collector in the form of a soft bag, simultaneously plays the role of one of the filters: air passes through the walls of the bag, and most of the contaminants are retained. Such containers are simple and inexpensive, while they can be made quite roomy. In addition, the vacuum cleaner with a bag remains operational in any position of the body. On the other hand, as the bag fills up, suction efficiency drops noticeably; and the cleaning procedure is usually quite troublesome — in particular, a lot of dust is raised into the air. Disposable bags, which are available for many models as an additional accessory, are deprived of such a drawback. However, on the other hand, the purchase of such bags is associated with additional expenses. As a result, this type of dust collector, although very popular in modern vacuum cleaners, is much less common...than the "cyclones" described below.

— Cyclone system (bagless). Dust collector based on a cyclone type air cleaner; usually has the form of a plastic bowl of a special shape. The principle of operation of such systems is that the air flow entering the dust collector is twisted into a spiral. In this case, the centrifugal force throws debris and dust out of the formed vortex, and the collected pollution sinks to the bottom of the dust collector. One of the main advantages of "cyclones" is the ease of cleaning: just turn the container over and the contents pour out of it without additional effort, and if desired, the dust collector can be easily washed. In addition, the suction force is practically independent of the degree of filling of the bowl. However, cyclones are somewhat inferior in capacity to bags, but because of the foregoing, this point is usually not fundamental. But the unequivocal disadvantages of this option are the higher cost of the same bags; a lower suction force for the same engine power; as well as a somewhat lower efficiency of catching fine dust. In light of the latter, "cyclones" have to be equipped with additional filters, which also periodically require cleaning. It is also worth bearing in mind that such systems are most effective with a regular, strictly defined position in space. If you deviate from this standard operational position, the efficiency of the dust collector may noticeably decrease, which leads to rapid clogging of the filters.

— Aquafilter. This type of dust collector looks like a container with water: the air drawn in by the vacuum cleaner passes through the liquid, which traps most of the contaminants. Such systems are highly efficient and hygienic: they capture various contaminants well, including even fine dust, without additional filters. In addition, the air released by the vacuum cleaner is additionally humidified which is especially useful in the cold season, when heating dries the air in the room. At the same time, the procedure for cleaning the dust collector itself is very simple and convenient: after cleaning, its contents can simply be poured into the sewer, while no dust rises into the air (unlike the process of cleaning cyclones and especially bags). On the other hand, it is desirable to wash and dry aquafilters after each use, which somewhat complicates maintenance. In addition, most of these vacuum cleaners are quite expensive, the passage of air through the water creates additional noise, and the water itself significantly increases the weight of the unit.
Separately, it is worth emphasizing that the presence of an aquafilter does not mean that the vacuum cleaner is washing (see above) or at least can wet cleaning (see "Cleaning type"). Quite a few models with an aquafilter work only in a dry format — and vice versa, units with a wet cleaning function may well be equipped with other types of dust collectors.

— Aquafilter + bag. This option means that the vacuum cleaner is equipped with two types of dust collectors at once — an aquafilter and a traditional bag. The features of both are described in detail above. Here we note that such models necessarily have a wet cleaning mode (see above) and/or a water suction function — an aquafilter is used for these purposes. But the bag, anyway, is intended for traditional dry cleaning. In general, this is the most common combination of the two types of dust collectors. The other variants described below are much less common.

— Aquafilter + cyclone. A combination similar to the aquafilter with a bag described above. The delivery set of such a vacuum cleaner includes two types of containers: an aquafilter for wet cleaning and/or water suction (this function can also be provided in vacuum cleaners with purely dry cleaning), as well as a cyclone system (see above) for sry cleaning .

— Cyclone system + bag. A combination found exclusively in dry cleaning models. Similar to the combinations described above, most often we are talking about the presence of two replaceable dust collectors of different types in the kit. The specific type is chosen depending on the situation. So, the cyclone system is convenient for collecting relatively large and heavy contaminants, and the bag handles better with fine dust.

Motor power

Rated power consumed by the vacuum cleaner. In models with power adjustment (see below), the maximum value is taken into account in this case. We are talking about the characteristics of the installed motor, which is the main, and in most vacuum cleaners, the only consumer of energy.

Higher power increases suction force and improves overall cleaning efficiency. In addition, a more powerful unit is easier to equip with a capacious dust collector. On the other hand, only vacuum cleaners of the same type with the same types of dust collectors can be directly compared by this parameter (see above for both). And even in such cases, the actual suction force (see below) may be different — and it is it that determines the real efficiency. However, the total power also allows you to generally evaluate the capabilities of the vacuum cleaner, including in comparison: a 1500 W model will significantly outperform its 800 W counterpart in efficiency (although it is impossible to say exactly by how much). But what definitely depends on this indicator is energy consumption.

As for specific power values, they are largely related to the type of device. For example, handheld models, robots and uproght units have low power — less than 1500 W(and often noticeably less). Such values are quite popular among other types of vacuum cleaners (conventional, industrial, workshop, etc.), but among them there are already more solid indicators — ...f="/list/90/pr-1067/">1500 – 1750 W, 1750 – 2000 W and even more than 2000 W.

Suction power

The suction power provided by the vacuum cleaner. For models with power adjustment (see below), in this case, the maximum value is taken into account. Note that "suction power" is sometimes erroneously also called the suction force, indicated in pascals; see below for more details.

Suction power is a key indicator that determines the capabilities of the unit: the higher it is, the more efficiently the vacuum cleaner can draw in various contaminants, and the better it handles with carpets, fabrics and other materials into which dust can penetrate deeply. On the other hand, high power inevitably affects the weight, power consumption, dimensions and price of the device. Therefore, it does not always make sense to chase the maximum values — you need to take into account the real working conditions and the general purpose of the vacuum cleaner.

The specific numbers found in this paragraph largely depend on the type of device. For example, in handheld household models, suction power does not exceed 100 W, and for conventional household units, an indicator of 100 – 150 W is still considered very limited. At the same time, we note that the minimum required for a full-fledged dry cleaning of smooth floors is considered to be 300 – 350 W, for carpet and other short pile coatings — 350 – 400 W, and for long pile materials and upholstered furniture higher rates are desirable. Vacuum cleaners with lower suction power values are intended not so much for periodic cleaning, but for constant (ideally daily) maintenance of cleanliness in an already tidy room.

As for the relationship between suction power and suction force, it is as follows: power is the suction force (thrust) multiplied by the airflow (performance). Without going into too much detail, we can say that the efficiency of the vacuum cleaner is determined by both of these indicators. And it is worth evaluating this efficiency by suction power (regardless of the specific relationship between traction and performance).

Dust collector capacity

The nominal volume of the dust collector installed in the vacuum cleaner.

This indicator largely depends on the type of unit (see above). For example, in most handheld household models, the capacity does not exceed 0.5 L. The volume of the container in upright vacuum cleaners and robots can be somewhat larger — among the first variety there are quite a few models for 1 – 2 liters or even more, and among the second — by 0.6 – 1 liter and a little more. For conventional vacuum cleaners, the minimum figure is actually about 0.8 – 1 L; dust collectors for 1 – 2 L and 2 – 4 L are very popular in such devices; the maximum capacity is actually 4 – 6 liters — units of a similar layout, but with a larger capacity, are usually referred to as household ones. In turn, relatively small containers are occasionally found among workshop models. However, in vacuum cleaners of this type, the capacity is generally quite large — it can reach 26 – 50 liters or even more ; the same applies to industrial (construction) units.

In general, a larger dust container allows you to work longer without interruptions. On the other hand, a capacious container itself takes up more space and, accordingly, affects the size, weight and price. So when choosing th...is parameter, it is worth considering the actual features of the use of a vacuum cleaner. Here we can give such an example: for a full-scale cleaning of an average city apartment, a capacity of about 1 – 1.5 litres is required. Thus, say, a 4-litre bag allows you to carry out two such cleanings with sufficient efficiency without unloading the vacuum cleaner. There are more detailed recommendations regarding the optimal volume of the dust collector, including specific cleaning options. These recommendations can be found in special sources.

Dust collector indicator

Presence in the vacuum cleaner dust collector filling indicator.

The general meaning of this function is already clear from the name: it is an indicator that informs the user about the fullness of the dust collector. At the same time, we note that the features of the operation of such a pointer may be different. The simplest option is a mechanical or electrical device that works when the amount of debris in the dust collector approaches a critical level. More advanced indicators can show a specific degree of filling at any time. In advanced vacuum cleaners, complex electronic systems can be used with values displayed on a display or a light indicator.

This function is most popular in models with bags (see "Dust collector") since without an indicator it would be necessary to control the fullness of such a vacuum cleaner manually — by opening the dust collector compartment and checking by touch how tightly the bag is filled. In cyclone systems, fill indicators are very rare and in aquafilters — even less often: both there and there, transparent materials are often used to allow you to see the amount of debris inside without opening the vacuum cleaner.

Compatible HEPA filters

Models of HEPA filters that are suitable for installation in a vacuum cleaner.

This information is needed mainly to find new filters to replace clogged or worn ones. Theoretically, knowing the HEPA model you can find detailed data about it. However, such details are usually not required; information on the fine filter class is enough to select a vacuum cleaner.

Noise level

The noise level produced by the vacuum cleaner during operation. Usually, the value for normal operation at maximum engine power is indicated here. With less power, the loudness of the unit may be lower, but the key is precisely the maximum indicator.

Regarding specific numbers, keep in mind that the decibel used to measure the noise level is a non-linear quantity. Therefore, it is worth evaluating specific indicators using special comparative tables. In general, vacuum cleaners are quite noisy appliances; so in this case, models are considered quiet if this indicator does not exceed 65 dB — this is the level of a loud conversation between 2 – 3 people at a distance of 1 m. The quietest of these models give out only 40 dB — this is the average volume of a person’s speech in normal tones (and the minimum volume allowed for constant noise sources in living quarters during the day). For louder units, the comparison table looks like this:

66 – 70 dB — loud conversations between several groups of people at a distance of about 1 m;
71 – 75 dB — the volume of a cry or laughter in full voice at a distance of about 1 m;
76 – 80 dB — the volume of a mechanical alarm clock or the engine of an old truck;
more than 80 dB — a very high noise level, exceeding the level of a loud scr...eam; when working with a vacuum cleaner having such specifications for a long time, it is highly desirable to use hearing protection.

Also note that the noise level largely depends on the engine power, as well as some other features (for example, it is strongly affected by the presence of an aquafilter — see "Dust collector"). At the same time, there is no hard connection here, and units with a similar set of specifications can differ markedly in actual loudness. In such cases, when choosing here, it is worth proceeding from the fact that a quieter vacuum cleaner will be more comfortable to use. However, it will most likely cost noticeably more.

Nozzle compartment

The presence in the vacuum cleaner of a special device for storing nozzles and sometimes other accessories.

Such a device can be either a compartment in the case or a set of external fasteners; the latter, in particular, is quite common in industrial vacuum cleaners (see "Type"). Anyway, the attachment compartment makes it much easier to store and transport various accessories: they are not scattered or lost, and you do not need to look for a separate package for them. However, such a compartment is often not intended for all nozzles and accessories but only for the smallest ones. However, even in such cases, it makes life much easier for the user. The disadvantages of such equipment include the fact that it inevitably affects the dimensions of the case. However, in full-size vacuum cleaners — conventional, industrial, for workshop (see "Type") — this disadvantage is often not important.
