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.

Compatible bags (dust collectors)

Models of replacement bags and/or other containers for waste (see "Dust collector") with which the vacuum cleaner is compatible.

This moment does not affect the functionality of the vacuum cleaner itself. However, knowing the model of the dust collector makes it much easier to find a spare or replacement dust collector. At the same time, we note that compatible models of such containers may differ markedly in specifications from the ones in the box. For example, many fabric bag vacuum cleaners also accept disposable paper bags; and some units are initially equipped with a dust collector of one type. However, if desired, they allow you to buy and install a dust collector of another type (for example, replace the bag with an aquafilter).

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.

Power cord rewind

System of automatic winding of a power cord. Usually, it is a special spool built into the body of the vacuum cleaner. To unwind a wire from such a spool, just pull it, and to rewind it, you need to press the button — and the built-in spring will twist the coil in the opposite direction, winding the cable around it.

The main advantage of the cord rewind system is obvious: it allows you to easily and quickly roll up the cable for storage and transport. In addition, in many vacuum cleaners with this function, the wire can be partially unwound, choosing its optimal length depending on the situation. The disadvantages of automatic cord rewind include some bulkiness and poor suitability for portable units. Such equipment nowadays can only be found among "full-size" vacuum cleaners — conventional (see "Type"), workshop and industrial.
