Comparison Mova M10 vs Mova K10

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).

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.

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.

A capacity of a tank for water or detergent a vacuum cleaner with a wet cleaning function is equipped with. (see "Cleaning type").

Large capacity allows you to work longer without refilling the tank. On the other hand, an increase in capacity has a corresponding effect on the size, weight and cost of the unit. Thus, manufacturers choose this parameter taking into account the general specialization and the “weight category” of a particular model. So, in robots (see "Type"), the volume of the water tank is, by definition, small. Even in the heaviest models, it does not exceed 650 mL. But other types of vacuum cleaners can differ markedly in this parameter.

In general, for non-robot units, a capacity of 1 liter or less is considered very limited, 1 – 2 liters is small, 2 – 3 liters is average, more than 3 liters is above average. However, it much depends on the type. For example, in conventional vacuum cleaners, the capacity does not exceed 2.5 liters, and "for workshop" models this is very little — in most cases, they have a tank capacity of 3 liters or more.

The type of power regulator provided in the design of the vacuum cleaner.

By itself , power adjustment allows you to adjust the operating mode to the current situation. For example, to clean a thick carpet, it is better to use a vacuum cleaner on full power, and on a delicate sofa or chair, it may be better to reduce the power. Types of power regulators are distinguished by location; options can be as follows:

— On body. The most popular option among modern vacuum cleaners. The main advantage of models with this design is that they do not require special hoses (unlike the units described below with adjustments on the handle). However, installation on the body is not very convenient for conventional vacuum cleaners (see "Type") — to change the power, you have to lean towards the body every time. However, for most users, it is not critical.

— On handle. The power regulator on the handle of the vacuum hose is convenient because the control is right at your fingertips, and you can change the power with just one movement of your finger, without bending over to the body. However, this convenience has a downside. So, some of these vacuum cleaners can only be fully used with special hoses; when installing a classic hose (without a regulator), the device, at best, will only work at full power, without adjustment, at worst, it will not turn on at all. A special hose is usually included...in the kit, but finding a replacement for it can be a quite troublesome (and costly) business. In other models, a wireless remote control is used, and its presence significantly affects the price of the unit.

— On body and handle. Vacuum cleaners combine both of the options described above. Usually, a hose with a regulator on the handle is supplied with such a unit. However, if necessary, you can install a regular hose and change the power with a switch on the body. Such control is the most versatile. Nevertheless, it is more expensive than each of the options described above.

The presence of a HEPA fine filter in the vacuum cleaner; also in this paragraph, the specific class of this filter is often specified.

HEPA (High Efficiency Particulate Absorbing) filters are designed to purify the air from the smallest mechanical contaminants — up to tenths of a micron in size. It allows you to trap not only fine dust but even bacteria. For comparison: the size of most bacteria starts at 0.5 microns, and the effectiveness of HEPA filters is evaluated by the ability to retain particles with a size of 0.1 – 0.3 microns. The most advanced such filters ( class 13 and above) are able to remove more than 99.9% of these particles from the air. Here is a more detailed description of the different classes:

— HEPA 10 – traps at least 85% of particles with a size of 0.1 – 0.3 microns;
— HEPA 11 – at least 95% of such particles;
— HEPA 12 – not less than 99.5%;
— HEPA 13 – not less than 99.95%;
— HEPA 14 – not less than 99.995%;

Note that pollution with a size of 0.1 – 0.3 microns is the worst-kept by HEPA filters, so with particles of other sizes (both larger and smaller), the efficiency of such elements will be even higher.

Regarding the choice for this parameter, it is worth noting that, in fact, it does not always make sense to pursue a high filtration class. For example, during wet cleaning with a washing vacuum cleaner (see abov...e), the HEPA filter, in fact, is not needed at all (in many models, it is recommended to remove it altogether for such cases). So if you plan to use such a vacuum cleaner mainly for washing, you can ignore this parameter. Another specific case is industrial units (see "Type"): they are often used for rough cleaning of large debris, where thorough air filtration is not required.

The self-cleaning function of the working nozzle simplifies the care of the device and increases cleaning efficiency. Usually, it is available in robot vacuums and upright models of vacuum cleaners. The nozzle self-cleaning is usually done with water. In the case of robots, a cleaning device is built into the docking station. In upright models, nozzle self-cleaning can be carried with a vacuum cleaner itself that can collect water or at a charging station where the turbo brush roller is cleaned.

The capacity of the battery installed in the vacuum cleaner.

Recall that batteries are used in all robots, as well as other types of vacuum cleaners for which mobility is important; see "Power supply" for details. As for battery capacity, theoretically, a larger battery allows you to work longer without recharging. However, there are nuances. Firstly, the actual battery life of the unit will also depend on its type, power and some features of the functionality. Secondly, the actual battery capacity is determined not only by this indicator but also by the voltage in volts. So if these batteries differ in voltage, you need to convert their capacity into watt-hours and use this data when comparing. These calculations are described in more detail in special sources.

In light of all this, only vacuum cleaners with similar specifications can be directly compared in terms of battery capacity. And it is best to evaluate the actual battery life by the directly claimed operating 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.
