Comparison Deerma VC03S vs Deerma VC01

General type of vacuum cleaner.

The general design and application features of the unit depend on this parameter. In addition to classic household models, the following types of vacuum cleaners are also produced nowadays: robotic vacuum cleaners, vertical(regular and vertical with portable), robot floor polishers, electric mops, electric brooms, household, manual models for household(including for bed and car purposes) and industrial use, full-size industrial (also known as construction), backpack and vacuum cleaners for fireplaces. Here is a more detailed description of each variety:

– Standard. Traditional household vacuum cleaners designed for cleaning apartments, residential buildings, small offices, etc. This unit consists of a relatively small body on characteristic wheels (for ease of movement across the floor) and a pipe with a brush connected to the...body using a flexible hose. This option is worth paying attention to if you need a “regular home vacuum cleaner” that is not designed to perform any specific tasks.

— Robot vacuum cleaner. Vacuum cleaners that work completely autonomously, without the need to control the device; The user's role is limited to only auxiliary tasks (unloading collected garbage, programming work, etc.). A robot vacuum cleaner usually comes in the form of a distinctive flat disc; its low height allows it to pass under furniture and other interior items. But specific work opportunities may vary. Thus, the simplest models move along random trajectories within a room, avoiding small obstacles and turning around when they reach walls or other large obstacles. More advanced devices may provide the ability to set “geography” and/or cleaning schedule, access to the unit via the Internet, etc. (see “Additional operating modes”, “Robot functions”). However, in any case, it is worth considering that robots do not differ in power and capacity; so it is hardly worth choosing such a device if you require high cleaning efficiency or expect large amounts of work. On the other hand, such equipment is ideal for maintaining already cleanliness in apartments, private houses and other similar conditions: a robot vacuum cleaner can be started at least every day without any special difficulties.

— Vertical. Vacuum cleaners of this type have a specific layout: the motor, dust collector and brush are mounted on a common vertical tube (hence the name), but as a rule, there is no hose in the design. Such units are designed primarily for domestic use; They're not great for cleaning hard-to-reach places (like under sofas or beds), but they do work well in large open spaces. In light of this, upright vacuum cleaners are quite popular, in particular in large offices and private homes. And some similar units are equipped with pipes of a hinged design (see “Pipe Type”), which simplify cleaning in the hard-to-reach places mentioned above.

— Manual (household). Handheld vacuum cleaners for household use are distinguished by their light weight, compact size and one-piece design: the motor, dust collector and suction nozzle (on which the brush can be placed) are combined in one body. Such units are not very powerful, but they are extremely mobile; in addition, they most often use batteries as a source of energy (see “Power”), which gives even greater freedom of movement. One of the most popular ways to use hand-held household vacuum cleaners is to clean the inside of a car; For this purpose, some models can be equipped with power from the cigarette lighter (either as an additional option or as the only source of energy). As for everyday use, such units are not suitable for full cleaning in an apartment/house/office, but they cope well with auxiliary, specific tasks: cleaning furniture and various small surfaces, collecting small debris in hard-to-reach places, etc.

— Manual (for bed). A type of hand-held vacuum cleaner designed for cleaning beds, upholstered furniture, mattresses, pillows, etc. The main feature of such units is their expanded capabilities for disinfection and control of parasites, primarily dust mites. Thus, an almost mandatory element of equipment for bed vacuum cleaners is a UV lamp (see below), and their suction systems and operating format are designed to effectively suck in dust mites - even tech “buried” to a considerable depth. If necessary, devices of this type can be used for more traditional cleaning, but their main purpose is to clean furniture and bedding.

— Manual (industrial). A type of industrial vacuum cleaner that does not have wheels and is designed to be carried from place to place by hand. It is worth saying that, for the most part, such units bear little resemblance to manual models for household use (see above) - they are more likely to resemble ordinary vacuum cleaners with a hose, without wheels and designed to be transported in the hands or on a shoulder strap (although there are exceptions). Power is usually supplied from a battery; Some models may also provide the ability to operate from the network. As a result, vacuum cleaners of this type are noticeably inferior in power to classic industrial models (also see above). On the other hand, they are more mobile - also due to their independence from sockets - and at the same time they are quite capable of coping with coarse construction and “industrial” waste.

– Vertical with portable. Models that combine the capabilities of vertical and manual household vacuum cleaners (see above). The traditional design of such a vacuum cleaner is a hand-held unit with a motor, dust collector and nozzle, complemented by either a removable vertical rod or an extension pipe. This design allows you to choose the format of work at your discretion and use one vacuum cleaner both for general cleaning (in a vertical format) and for small specific tasks (in a portable format). The main disadvantage of this option is the smaller capacity than that of vertical and conventional household vacuum cleaners - this somewhat complicates the use for large-scale cleaning. However, due to their versatility, devices from this category are now much more popular than purely vertical units.

– Robot floor polisher. Devices for wet cleaning of non-carpeted floors. Such units require a minimum of effort from the user - usually it is only necessary to periodically add detergent and clean a special napkin for wiping floor coverings after the end of the process. Robot floor polishers move independently across the floor, change direction when encountering obstacles, and build a route in such a way that, if possible, they process the entire area in the work area. Many models are capable of independently returning to the docking station to charge the battery, and to increase the convenience and efficiency of operation, various additional functions can be provided: work on a schedule, mapping, IR barriers to limit movements, etc. Robotic units for wet cleaning are excellent for “on-duty” maintenance of order in relatively clean numbers.

– Electric mop. Devices for wet cleaning of floor coverings, which are a modern version of a mop with an electric motor. The engine in their design is assigned various tasks such as vibration or rotation of the cleaning head to ensure more thorough cleaning. Many models of electric mops have a built-in tank for water or detergent, which makes it possible to spray liquid on the floor during the wet cleaning procedure. As for working attachments, most often such mops are equipped with a floor polisher or an electric turbo brush (see “Attachments and their functions”).

– Electric broom. Electrically powered sweepers that drive brushes or suction mechanisms to collect debris. Rotating brushes in the design of electric brooms effectively sweep up debris and direct it into a special dust container. Such devices are suitable for quick, everyday cleaning of floor coverings - they are lightweight, maneuverable and powered by a built-in cordless battery.

– Household. Vacuum cleaners designed for professional cleaning of large volumes. Such units are popular in cleaning companies, but they can also be useful for private use. Typical examples of the use of economic models are cleaning a home workshop or garage, hotel numbers, etc. The layout of vacuum cleaners of this type resembles traditional models - a body with a pipe on a hose - but they have a number of differences. The most noticeable of them are the large dimensions and the vertical layout of the hull with an overhead engine. In addition, household models are distinguished by high power and capacity (from 6 liters or more). They may provide wet cleaning, although most models only work in the traditional dry format (see "Cleaning").

— Industrial (construction). Vacuum cleaners designed for cleaning industrial facilities - construction sites, factory floors, etc. They are in many ways similar to the household ones described above: most models have an elongated body with a top-mounted engine, high power and large capacity. The main difference is that industrial units are designed for coarse construction waste, which more “delicate” types of vacuum cleaners cannot handle. And to collect such waste in such units, containers in the form of rigid containers are used; such containers can be supplemented with paper bags for ease of unloading, but this is not strictly necessary. Also in this variety, the water collection function is very popular (see below), although industrial vacuum cleaners are never made to be detergent and most often do not even provide for wet cleaning. In addition, only bags are used as dust collectors - aqua filters and “cyclones” are, in principle, not found in such units.
Please note that this category includes only industrial vacuum cleaners of a classic design that are moved on wheels. Handheld and backpack models are placed in separate categories (see below).

– Backpack. Vacuum cleaners carried on the back like a backpack - hence the name. This design combines the advantages of classic and manual format vacuum cleaners: the unit can be made quite powerful, spacious and at the same time mobile. True, most models of this type operate from the mains; battery solutions are less common; however, even when powered from a wall outlet, you can achieve good freedom of movement. This makes backpack vacuum cleaners well suited for situations where flow Rate and mobility are needed at the same time; A typical example is cleaning the cinema hall between screenings. The main disadvantage of this variety is its rather high cost, due to a number of design features.

– For fireplaces. Specialized vacuum cleaners designed for collecting coals and ash in fireplaces, stoves, barbecues, charcoal grills, etc. One of the key features of units of this type is resistance to high temperatures, which allows you to collect even coals and ash that have not completely cooled down. For this purpose, the hoses and brushes of fireplace vacuum cleaners are made of non-flammable, refractory polymers, and a metal container is usually used as the main container. In addition, the filters in such models are characterized by increased efficiency and resistance to fine dust; For added convenience, the filter may also be self-cleaning (see below). It is worth considering that vacuum cleaners from this category are mostly quite expensive; therefore, it makes sense to buy such equipment only in cases where you often have to deal with cleaning fireplaces - for example, if the fireplace is installed in a restaurant or hotel lobby and is used every day “during the season.”

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.

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 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.

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.

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.

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.
