Type

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.”

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.

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.

Water tank capacity

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.

Additional operating modes

Additional modes of operation provided by the robot cleaner (see "Product type").

First of all, let us clarify that the standard modes, in this case, include two formats of cleaning at standard power — continuous, in which the vacuum cleaner carefully cleans the entire room (or its specified area), and chaotic, in which it moves randomly within the working area. Other ways of working are considered additional; their list is given in this paragraph. Among the most common additional modes are spot cleaning (Spot), perimeter cleaning (Edge), and turbo mode. In addition, a fairly popular function is the Zigzag. Here is a detailed description of the different options:

— Spot cleaning (Spot). A mode that allows you to use the vacuum cleaner for targeted cleaning of a relatively small area of the room — for example, when spilling a small amount of debris. Most often, this programme works as follows: the robot moves to the centre of a user-defined zone, and then starts moving from this point in an expanding spiral and stops at a given distance from the starting position.

— Perimeter cleaning (Edge). A mode that allows you to start the vacuum cleaner around the perimeter of a given zone. By the name, it is mainly used for cleaning along the walls of the room: a lot of dirt accumulates in these places, which are difficul...t to remove when using standard cleaning modes.

— Turbo mode. Power mode for more suction force. Usually, the movement of the vacuum cleaner, in this case, can be carried out according to any programme available in the settings — both standard (combing, random movement) and additional (Spot, Edge, Zigzag). Anyway, the turbo mode is useful primarily for cleaning carpets and other floor coverings with pile, for which the standard power of the vacuum cleaner is not enough. However, working at increased traction increases the load on the unit and increases its wear. Therefore, most models have restrictions on the maximum time of continuous operation in turbo mode and sometimes on the minimum duration of breaks between switching on this mode.

— Zigzag. Zigzag movement is a kind of transitional variant between the orderly combing of the room and the random choice of direction. Zigzag allows you to achieve greater efficiency than chaotic movements. In addition, with such a movement, it is easier to compensate for the presence of various obstacles and ensure thorough cleaning of the entire given area.

Robot features

Additional functions provided in the design of the robot vacuum cleaner (see "Type").

Most often in modern robots you can find such special functions: scheduled cleaning, fall protection, obstacle sensor, object recognition, water supply adjustment, control via the Internet, remote control and video surveillance camera. Here is a more detailed description of each of them:

- Scheduled cleaning. The ability to set a schedule according to which the vacuum cleaner will clean automatically, without additional commands from the customer. At the same time, the specific features of such programming may be different, they should be specified separately. So, in the simplest models, the schedule is limited to individual hours within a day - for example, from 16 to 17; at the set hours, the vacuum cleaner is switched on every day. More advanced devices may provide a schedule for the days of the week or even for the dates of the month or year. In any case, this function greatly simplifies the use: it is enough to set the schedule once - and you can not worry about cleaning for at least a few days; especially since most models with this capability also have the function of docking...(see “Robot Configuration - Charging Station”), and the customer only needs to periodically empty the dust container (which is even more simplified if there is a docking station with a bag - see . below).

- Fall protection. Special protection that prevents the vacuum cleaner from falling off steps, high thresholds, etc. In most cases, the basis of such a system is one or more sensors located on the underside of the case. When the vacuum cleaner travels to the edge of the surface being treated, the sensor reacts to this edge - as a result, the device stops and changes direction in order to avoid falling.

- Obstacle sensor. Sensor (or sensor system) for detecting obstacles in the path of the vacuum cleaner. The specific type of such sensors can be different: ultrasonic, infrared, laser, contact, etc. However, in any case, this function allows the device to move in space, avoiding collisions and determining the best detour path. Note that models without such a sensor, for the most part, are also able to bypass obstacles - however, for this, the robot must not only stumble upon a foreign object, but try to pass through it. And only in case of failure, the trajectory changes - moreover, randomly, far from always in the optimal (or at least suitable) direction.

- Object recognition. The function of recognizing various objects on the floor that may interfere with the cleaning process. It is implemented through the presence of a front camera to adjust the optimal route for the vacuum cleaner along the perimeter of the serviced area. The camera in the design of the robotic cleaner reads the outlines of objects and allows you to bypass such obstacles. As a result, slippers, socks thrown under the bed, children's's toys and wires will no longer interfere with the movements of the vacuum cleaner. The function is of particular benefit in the presence of pets at home that are not accustomed to the tray - the robot will calmly has their waste products and keep the nervous system of pet owners healthy.

— Adjustment of water supply. Dosing system for the degree of wetting of the washing cloth in automatic mode. The ability to select the intensity of the water supply allows you to adjust the operation of the robotic vacuum cleaner for different types of floor coverings. For example, for parquet and laminate, the customer can set a low water flow rate, and for less whimsical tiled flooring, a high water flow rate. Also, the vacuum cleaner can turn off the water supply to avoid leaks, for example, when charging. In advanced models of robotic vacuum cleaners, the function of choosing an individual degree of wetting of the napkin for each of the rooms of the dwelling is often incorporated.

— Docking station with a bag. Docking station with its own trash bag. Upon arrival at such a stand, the robot can not only recharge the battery, but also carry out self-cleaning - unload the collected garbage into an external container; The capacity of the dock, as a rule, is enough for several unloadings. The convenience of this function is obvious: it allows the device to work longer without customer intervention, eliminates the need to manually clean the vacuum cleaner when the dust container is full (besides, unloading garbage from the dock is usually easier than such cleaning). True, and such opportunities are quite expensive.

- Management from the Internet. The ability to control the vacuum cleaner via the Internet - most often through a special application on a smartphone or other gadget (theoretically, such control is also possible through a web page that opens in any browser, but in practice this method is almost never used). The robot itself is connected to the network via Wi-Fi. The main advantage of this function is obvious - it allows you to give commands to the device from anywhere in the world where there is Internet access. In this way, for example, you can start a cleaning programme the day before you return from vacation in order to return to a freshly cleaned apartment. And the vacuum cleaner, in turn, can send various notifications to the customer - about the state of the battery, the progress of cleaning, the fullness of the dust container, etc.

- Remote control. A classic remote control that allows you to give commands to the device from a distance. As a rule, such a remote control covers all the main functions of the vacuum cleaner, and in many models it also allows you to directly control the movement. In any case, without remote access, it would be very difficult to control a moving vacuum cleaner - you would either have to wait until it finishes working, or catch the unit on the go. In light of this, this feature is very popular; however, on sale you can find a lot of robots without a remote control. As a rule, these are either the simplest budget devices with a random movement mode and without any additional functions, or advanced models where a smartphone / tablet with an application is used for control.
We also note that the remote controls in robotic vacuum cleaners usually work via an infrared channel - similar to remote controls for TVs, air conditioners, etc. Thus, to receive a command, the vacuum cleaner must be in the line of sight. However, in most cases this can not be called a serious inconvenience.

- Videcam. Own surveillance camera built right into the vacuum cleaner. This feature is only found on web-based models (see above); it allows you to use the robot as a remote video surveillance system and control the situation in the room, being outside and watching the picture from the camera on the smartphone screen. Also, the built-in camera can be used in the mapping system (see "Building a room map") - however, we note that not every vacuum cleaner with a built-in mapping camera has a video surveillance function.

Mapping system

The mapping system is provided in many modern robots. It allows you to determine the size of the room and the location of various obstacles present in it, as well as fix the route travelled by the vacuum cleaner. There are various systems according to their principle of operation, among which there are three types. Methods for building a map based on data from a sensor or a camera belonging to the basic level. But building a map using a laser rangefinder (lidar) gives more accurate results and elevates the device to a higher category. Accordingly, the presence of such a system affects the overall cost but provides several advantages. Firstly, cleaning efficiency is noticeably increased: the robot remembers which areas have already been cleaned and pays maximum attention to untreated areas. Secondly, movements are carried out along optimal trajectories, the shortest paths; this saves energy and extends battery life. Thirdly, it becomes possible to effectively clean large spaces of complex shape (for example, the entire apartment). And if the vacuum cleaner is controlled through an application on a smartphone or other gadget, the created map is displayed in this application. It gives various additional features: correcting the collected data, real-time device control, building routes, limiting cleaning through the application (see above), etc. P.

As for the methods of building maps (and further naviga...tion), there are mainly such options:

— Camera. Such systems work because the robot, using a digital camera, “examines” the room, remembering its shape and the location of objects. A fairly simple, inexpensive and at the same time practical way: usually, the camera is supplemented by an object recognition algorithm, thanks to which it can recognize obstacles stored in memory, regardless of their position in space. It is useful when you have items that are frequently moved around, such as chairs. In addition, if the map is displayed in an application on a smartphone, it looks like not just a conventional diagram but a real image, which is very convenient. The disadvantages of this option include perhaps a slightly lower accuracy than that of sensors and even more so rangefinders. However, it is not critical, and in some models, information from the camera can be supplemented with data from sensors, which completely reduces this drawback to zero.

— Sensors. Creating a map through the operation of various special sensors. Most often, such systems use sensors for obstacles and fall protection (see "Robot features"), working in conjunction with an inertial module that determines the current position of the robot in space. Receiving a signal from one of the sensors, the robot saves data on the trigger point; from such points, as a result, the map is formed. It is a fairly reliable method. It is inferior in accuracy to rangefinding cartography (see below) but it is also cheaper. The disadvantages of this type of mapping include some inconvenience when managing via the application. The map is displayed in the form of a scheme map, which is not always convenient for the user. In addition, vacuum cleaners with such systems are unable to respond in advance to a change in the situation — this change is determined only when the sensor is triggered again.

— Rangefinder (laser). Building a map using a laser range finder — lidar. Usually, such a rangefinder covers the space all 360 ° around the vacuum cleaner, scanning the space at a high frequency (hundreds and even thousands of measurements per second in all directions). It allows you to create very accurate maps in a short time and with a minimum of movement in space. In addition, the rangefinder is used not only during the initial mapping but also during further work. Thanks to this, the robot instantly reacts to changes in the environment and corrects the trajectory of movement. The main disadvantage of such systems is their rather high cost. In addition, as in the case of sensors, when controlling the vacuum cleaner from a smartphone, the map is displayed in the form of a scheme map, which is somewhat less convenient than when using cameras.

— Rangefinder + camera. It is the most advanced and functional option: the laser provides high accuracy in determining distances and a quick response to changes in the environment. And the camera allows you to create not just scheme maps but realistic images of premises that are convenient when controlled via a smartphone. The main disadvantage of such combined systems is their very high cost. Therefore, they are extremely rare, mainly in premium robot vacuum cleaners.

Cleaning area

Cleaning area for which the robot vacuum cleaner is designed.

It is the maximum size of the room that the device can effectively process without the need to empty the dust container or charge the battery. It is worth choosing according to this parameter with a certain margin — this will give an additional guarantee in case of various emergencies. On the other hand, you should not take too much stock: after all, a large cleaning area requires more capacious batteries and capacious dust collectors, which significantly affects the dimensions, weight, and most importantly, the price of the vacuum cleaner.

As for specific figures, the most modest models nowadays are designed for 45 – 60 m2 — this corresponds to an average apartment with 1 – 2 rooms. And in the most advanced and heavy devices of this type, the cleaning area can be 300 m2 or even more.
