Cleaning type

Type(s) of cleaning for which the vacuum cleaner is intended.

Almost all modern units have the function of dry cleaning. In turn, wet cleaning is usually provided as an addition to the dry mode and is rarely used as the only cleaning mode. Here is a more detailed description of these options:

— Dry. Traditional cleaning without the use of water: the vacuum cleaner draws in air, collects debris in the dust container and purifies the air through a filter system. It is considered somewhat less effective than wet, but it has practically no restrictions on its use: almost any material can be cleaned in this way. In addition, such cleaning is much easier for the user (no need to fill or even drain water). And the units themselves, which have only a dry mode, are simpler and more inexpensive than similar models with a wet cleaning function. In addition, for some types of vacuum cleaners, this is the only available option. A typical example is handheld models of both household and industrial specialization (see "Product type").
We note that the possibility of water suction (see below) can be provided even in vacuum cleaners with a purely dry type of cleaning (most often in industrial and household models — see "Product type").

— Wet and dry. The ability to carry out not only the dry cleaning described above but also wet cleaning. It is in this fo...rmat that all washing vacuum cleaners work (see below). However, we emphasize that not every unit with the wet cleaning function is a washing vacuum, and even the water suction function (also see below) is not always available in such models. The fact is that many vacuum cleaners with this feature use the simplest possible operation mode: water from a special container is supplied to a special nozzle and moistens the floor after cleaning. However, even such a treatment method significantly increases efficiency compared to conventional dry cleaning. An additional nozzle collects dirt that the vacuum cleaner could not draw in, and moistening the floor refreshes the room and prevents dust from rising into the air that could remain after cleaning. For washing vacuum cleaners, in turn, other advantages are also common. The main disadvantages of all models with two types of cleaning are the complexity of the design, greater weight and higher cost than similar units with only a dry format.

— Wet. This option means that the vacuum cleaner is designed for wet cleaning only and does not require a dry operation. See above for details on these modes. Here we note that it is a very rare option used in single models of conventional and upright vacuum cleaners (see "Product type").

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 force

The suction force provided by the vacuum cleaner. It is indicated by the maximum vacuum (negative pressure) that the unit can create at the working nozzle.

Note that this parameter is sometimes confused with the suction power described above, which is indicated in watts. Yes, suction force to some extent determines the efficiency of the unit. However, this efficiency also depends on the performance (airflow). And the suction power, indicated in watts, takes into account both of these parameters — it is determined by multiplying the suction force by the performance (see above for more details). For this reason, there is no strict relationship between this force and suction power: for example, a vacuum of 25,000 Pa can be found in models with 250 W, 200 W and even 150 W of power.

As for the practical significance of this spec, in general, a higher suction force allows you to work more efficiently with high resistance. For example, when processing carpets with a long pile. On the other hand, more pascals (with the same number of watts) means less airflow and, accordingly, less efficiency for large amounts of work at low resistance (for example, cleaning large rooms with parquet floors). Thus, it makes sense to pay attention to this indicator mainly in cases where high suction force is fundamental for you. In other cases, it is worth evaluating the capabilities of the vacuum cleaner in terms of suction power in watts.

Note that for a number of...reasons, the suction power is most often specified for robot vacuum cleaners (see “Produc type”). For such models, a value of 1500 Pa and below is considered very small, 1500 – 2000 Pa — medium, 2000 – 2500 Pa — high, more than 2500 Pa — very high.

It is also worth mentioning that the indication of suction force is often used as a publicity trick — to improve the impression of the product. For example, the suction power of 150 watts in itself is quite modest. But at the same time, the suction force of such a vacuum cleaner can be 25,000 Pa — a very impressive figure, especially for an inexperienced buyer, but having a very indirect relation to real efficiency. Especially often, such tricks are used among upright models and the already mentioned robots — these varieties initially do not differ in high power in watts. For many of these units, the characteristics only indicate the vacuum in pascals without specifying the suction power. It further enhances the impression: for example, in the specs of a modest robot, the figure "3000 Pa" looks much more impressive than "40 W". However, such figures have a very weak relation to the real capabilities of the unit and if they are not supplemented by data on suction power in watts, they should be considered solely as bait for a not particularly sophisticated buyer.

Nozzle functions

We emphasize that in this paragraph we describe the functions of the vacuum cleaner nozzles and not the types of nozzles themselves. It is because one device can have several functions at once: for example, a crevice nozzle, which is also used as a dust nozzle. So the total number of nozzles may differ from the number of items in this list. Although exceptions are possible (when several nozzles of the same type are supplied in the kit, differing in size).

The main functions found in the nozzles of modern vacuum cleaners are as follows: combined (floor/carpet), crevice (including telescopic crevice), dust brush, for sofa, parquet, turbobrush(regular, mini turbobrush or electricturbobrush . However, sometimes the best choice is vacuum cleaners without turbobrushes, and for handheld vacuum cleaners — angle brush, microfibre, mop, floor polisher (for wiping), for mattresses, for animals, twister for hose, siphon nozzle, ...f="/list/90/pr-41987/">flexible hose and tool adapter. For robots, side brushes are important, which can be one or two. Here is a detailed description of these, as well as some other features:

— Side brush. Function found exclusively in robots (see "Product type"). Such a brush protrudes to the side beyond the body and captures the space on the side. It increases the overall width of the operating area and allows you to effectively clean places that are inaccessible to the main brush of the robot (which is located at the bottom of the body). Typical examples of such places are the space near the walls of the room and at the bases of cabinet furniture, crevices under baseboards, etc. Note that this option is indicated when there is only one side brush; the presence of a pair of such brushes is specified separately (see below).

— 2 side brushes. The presence in the robot vacuum cleaner of two side brushes on both sides of the body. See above for more details on the side brush as a whole. This design option slightly increases the cost but significantly improves efficiency compared to a single side brush. The width of the operating area is evenly increased. And when cleaning hard-to-reach places, it does not matter which side the vacuum cleaner is turned to such a place — there is an additional brush on each side.

— Combined (floor/carpet). A function that allows you to use one nozzle for dry cleaning of various types of floor coverings — both hard (linoleum, parquet, laminate, tiles ...) and carpets. Accessories with this function are extremely popular. They are found in almost all conventional vacuum cleaners (see "Product type"), in many household vacuums, as well as professional models (except hand-held industrial and fireplace vacuum cleaners). The nozzle itself usually has a T-shape, rather large dimensions and a swivel mount that improves mobility. And adjustment for different types of surfaces is carried out due to the retractable brush. The bristles of such a brush are convenient for cleaning hard surfaces. And when cleaning carpets and other fleecy materials, the brush can be removed so that the nozzle fits snugly against the pile and effectively draws dust and small debris out of it.

— Crevice. This function means that the nozzle is equipped with a flat working part with a narrow slot at the end. This design is suitable for cleaning hard-to-reach places — spaces between pieces of furniture, crevices under baseboards, gaps between radiator sections, etc. The width of the crevice nozzle (and, accordingly, the length of the crevice) usually does not exceed the diameter of the vacuum cleaner pipe, but the length of the flat part can be different. Moreover, each option has its advantages: long models can reach further into narrow gaps, while short ones are more manoeuvrable and more comfortable in general.

— Dust. A function that allows you to collect dust from small hard surfaces, such as armrests of chairs, picture frames, lamp shades, etc. Traditional accessories with this ability are in the form of small round brushes but there is another variety — wider nozzles (also with brushes), somewhat similar to a smaller version of the floor/carpet format fixtures (see above). The second variety is often referred to as furniture nozzles. Some of these accessories have removable bristles and can be used as nozzles for a sofa (see below).

— For sofa. A function that allows you to effectively clean the upholstery furniture and other similar items — mattresses, car seats, etc. Brushes with this function can have different designs and application features. The simplest option is a T-shaped device, similar to a reduced combination nozzle (see above), which does not have bristles, but is often equipped with strips of the fine pile — they effectively collect hair and wool from the upholstery. Some of these devices are equipped with removable bristles and can also be used as dust ones (see above). A more expensive and advanced option is beater brushes that provide additional impact; this effect increases efficiency, allowing the removal of dust and other small contaminants even at fairly great depths. Also, some turbobrushes and mini turbobrushes may be intended for upholstered furniture (see below). For vacuum cleaners equipped with such accessories, both this function and the mini turbobrush are indicated in the specifications.

— Parquet. A function that allows you to use the nozzle for effective and gentle cleaning of parquet and other hard floor coverings. A nozzle with this function is similar to the combined one described above. However, the bristles in it are non-removable and they are designed to minimize the risk of damaging the coating. Nevertheless, the specific characteristics of such nozzles may be different. So if you have to work with delicate surfaces — the ability of such an application needs to be specified separately.

— Turbobrush. The working part of a classic turbobrush is a horizontal roller driven by airflow. This design allows you to effectively collect hair, wool and other similar debris (for example, thread). But the specific design and specialization of the turbo brush can be different. Models, where the roller is equipped with bristles, are designed mainly for fleecy surfaces like carpets. And some of these nozzles are reduced in size and are intended for cleaning upholstery furniture (in such cases, the function “for sofa” is also indicated in this list). In turn, rollers with soft short pile are great for smooth surfaces — including rather delicate ones, like parquet. Thus, there may be several turbobrushes in the kit — for different tasks.
Note that the turbobrush must be periodically cleaned from collected contaminants. In addition, such a nozzle slightly reduces the overall suction efficiency since part of the suction power is spent on rotating the roller. Electric versions are deprived of this drawback, but they also have their own disadvantages — see below for more details. Also note that even mechanical turbobrushes are quite expensive, even though their advantages over conventional fixed attachments become noticeable only when cleaning hair and long hair. Therefore, if you do not regularly have to deal with such pollution, it most likely makes sense to choose a vacuum cleaner without a turbo brush.

— Mini turbobrush. A reduced version of the turbobrush — conventional (see above) or electric (see below). Compactness allows to effectively use such a brush in hard-to-reach places and on small surfaces. Actually, the main purpose of most mini-turbo brushes is to clean wool and hair from upholstered furniture. In addition, some of these nozzles are also well suited for cleaning carpets on narrow stairs.

— Electric turbobrush. Devices that are almost completely similar to the turbobrushes described above with the exception that the roller, in this case, is driven not by an air stream but by an electric motor installed in the nozzle itself. The main advantage of electric nozzles is the higher efficiency (with the same suction power). Firstly, such nozzles practically do not affect suction power, while traditional mechanical turbobrushes lose part of this power, spending it on rotating the roller. Secondly, the speed of rotation of the electric turbo brush does not depend on the airflow, and the torque of the electric motor can be quite high. The downside of these advantages is the complexity and high cost of the nozzles, as well as the need to use special tubes and hoses with them, supplemented by wiring to power the electric motor.

— Angle. This function means that the vacuum cleaner is equipped with a device that allows you to place the working nozzle at an angle (usually perpendicular) to the main tube. In this case, the specific design of such a device may be different. In some models, this is an additional adapter in the form of an L-shaped tube on which different nozzles are installed. In others, the L-shaped nozzle itself is made of one type or another — for example, dust (see above). Thirdly, such an adapter or nozzle is equipped with a swivel joint, which allows you to place the working part at different angles. All such devices make it much easier to clean in some hard-to-reach places.
We note that it makes little sense to use angle adapters with combined floor/carpet nozzles (see above) — such devices usually have swivel joints and do not require additional equipment to rotate them.

— Microfibre. Microfibre cloth for wet cleaning. It is worth saying that for some models with such equipment, only dry cleaning is claimed in the specification (see "Cleaning type"). But this only means that the vacuum cleaner does not have its sprayer and the microfibre must be wetted manually. In general, such a nozzle is most popular in robots. However, it is also found in upright models (mostly upright with handheld ones, see "product type"). In the first case, the microfibre is installed on the lower part of the body. In the second case, on one of the working nozzles. However, microfibre is effective in wet cleaning: it perfectly absorbs dirt and is easily washed from them. On the other hand, it makes sense to use such a nozzle (like any wet cleaning device) mainly on linoleum, parquet and other hard surfaces.

— Twister for hose. A small cyclone-type container (see "Dust collector") mounted directly on the hose of the vacuum cleaner; usually at the joint with the pipe. Most often is used in vacuum cleaners with a bag. Twister performs several useful functions at once. Firstly, it traps most of the dust and allows you to work longer without cleaning the bag; and cleaning the twister is much easier and faster than cleaning the bag. Secondly, the container on the hose is usually made transparent which makes it easier to monitor the amount of dust collected. Thirdly, it is easier to get a small but necessary item (coin, memory card, etc.) accidentally sucted by the unit from the twister. The disadvantage of such a device is that it makes the hose more bulky and heavy, reducing mobility.

— Siphon nozzle. A function that allows you to use a vacuum cleaner to clean sewage in kitchen sinks. For such cleaning, specialized nozzles are used, which are similar in shape and principle of operation to plungers. The difference is that the suction that clears a clogged pipe is created by the operation of the vacuum cleaner. All units equipped with such nozzles have the function of water suction. However, they may not be washing vacuums(see above) and may not even have the ability of wet cleaning (see “Cleaning type”).

— Flexible hose. The presence of this function is specified for vacuum cleaners that are not related to conventional ones (see "Product type") — the latter is equipped with a hose by default and there is no need to specifically mention this accessory for them. In other cases, a flexible hose can be both the main working accessory (for example, industrial vacuum cleaners, including most handheld ones) and an additional accessory (for example, upright units). In the latter case, the hose allows you to reach places that are inaccessible without such a device when cleaning.

— Adapter for tools. A function that allows the use of a vacuum cleaner in combination with various electric and sometimes pneumatic tools for cleaning production waste right in the process. It is found mainly in professional-level units — industrial (including handheld) and for workshop (household vacuum cleaners are poorly suited for working with large amounts of chips and sawdust). However, the specific design and purpose of such an adapter may be different. Most often, it has the form of a kind of cone, made up of "steps" of different diameters and is used to connect to tools that are originally equipped with nozzles for a vacuum cleaner. At the same time, the dimensions of the "steps" of the adapter correspond to several standard diameters in which nozzles are made on tools. (Some units with this equipment even have an auto-on function when the tool is turned on; see "Built-in socket" for more details). However, before buying such a unit, it's ok to clarify the compatibility of the adapter with specific tool models.
Another version of the "tool" adapter is a kind of cover that covers the area around the place of work and is used mainly with drills and hammers. In such a cover there are two holes: one — with a pipe for connecting a vacuum cleaner, the second — for the working nozzle of the tool. The circumference of the hole for the tool is often made of characteristic "petals", reducing the risk of damage to the drill or other nozzle in case of accidental contact with the adapter. However, such devices are rarely included in the package — they are more popular as separately sold accessories.

In addition to those described above, in modern vacuum cleaners, there are other, more specific functions of nozzles, in particular:

— Washing. Sometimes the presence of this function is specifically indicated for washing vacuum cleaners — mainly to clarify the features of the washing nozzle. So, it can be intended for different surfaces (for smooth floors or carpets/furniture), have different sizes, etc. However, the principle of construction of all such nozzles is the same: the design necessarily has a nozzle for spraying detergent, and the working part usually has the appearance of a thin and rather wide gap. This design most effectively handles with the collection of liquid.

— Ultraviolet lamp. An ultraviolet lamp, built-in in one of the main nozzles — most often in combined for floors/carpets (see above), but exceptions are possible. Such equipment allows the vacuum cleaner to carry out not only ordinary cleaning but also additional disinfection: UV radiation handles well with most pathogens. At the same time, it is harmless to people and pets if you follow the safety rules specified in the documentation for the vacuum cleaner. Of course, we are not talking about one hundred per cent disinfection. However, the use of a UV lamp anyway improves the quality of cleaning.

— Flexible crevice. A special variety of the crevice nozzles described above is with a flexible working part. This design of the nozzle allows it to penetrate even into curved slots that are inaccessible to a traditional rigid design.

— For pets. This function allows you to use the vacuum cleaner to collect hair from pets that tend to shed heavily, especially long-haired dogs and cats. A specialized nozzle for such tasks is an improved “comb”: it effectively removes loose hair, which is immediately drawn in by a vacuum cleaner. And at the same time does not create discomfort for the animal (the main thing is to accustom the pet to the noise of the vacuum cleaner itself).

— Pulverizer. A feature found in some vacuum cleaners with a wet cleaning function (see “Cleaning type”). Usually, it is implemented through a special nozzle designed exclusively for spraying liquid.

Battery voltage

The rated voltage of the battery used in the vacuum cleaner with the corresponding type of power supply (see above).

Initially, manufacturers select the characteristics of the battery (including voltage) in such a way that the vacuum cleaner can be guaranteed to deliver the power claimed in the specifications. Therefore, when choosing this indicator often does not play a decisive role. However, it can also be useful in such cases — for the most reliable comparison between models with different battery capacities in ampere-hours. See "Battery capacity" for details.

In addition, voltage data can be useful during operation — for example, to find a spare/replacement battery or a third-party charger.

Battery run time

The operating time of a battery-powered vacuum cleaner (see "Power supply") on a single battery charge.

Usually, the average operating time in normal mode is indicated here. Accordingly, in fact, the battery life of the vacuum cleaner may differ slightly from the claimed one, depending on the chosen application format. Nevertheless, the operating time indicated in the specifications is a fairly reliable indicator; it can be used both for a general assessment of battery life and for comparing the selected vacuum cleaner with other models.

Separately, we note that increasing battery life requires either the use of more capacious (and therefore more expensive and heavier) batteries or a decrease in engine power (and the efficiency of the unit as a whole). So it is worth looking specifically for a long working vacuum cleaner if these moments are outweighed by a long operating time.

Charging time

The time required to charge the cordless vacuum cleaner fully (see "Power supply").

Larger batteries tend to take longer to charge. On the other hand, modern batteries can use various solutions that speed up the process, so there is no strict dependence here.

Separately, we note that the speed of charging batteries is usually uneven: at first, the process is fast, then it gradually slows down. So if, for example, the specifications indicate a charging time of 2 hours, then charging from 0 to 50% will take a little less than an hour, and from 50% to 100% the remaining time.

Charging station

A feature found in battery-powered vacuum cleaners - most robots, as well as some upright models (see "Type").

The charging station combines the functions of a charger and a storage device. Its specific design may be different. Robots are equipped with a floor docking station; most of these devices can remember the location of the station and, if necessary, return to it on their own — for recharging or at the end of the program. In other types of vacuum cleaners, the charging station usually is wall-mounted. The vacuum cleaner hangs on it while connecting to a power source to charge the battery. Some of the wall attachments can also be used to charge the battery removed from the vacuum cleaner. However, we emphasize that traditional chargers that do not provide for hanging on the wall and fixing the entire vacuum cleaner are not considered charging stations. Less common are floor-standing charging stations for upright vacuum cleaners and desktop docking stations for charging portable (handheld) models.

In any case, this function is almost standard for robots, but upright and handheld household vacuum cleaners equipped with a charging station, in general, are quite advanced and expensive devices.

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.
