Comparison Xiaomi Robot Vacuum S10 vs Xiaomi Robot Vacuum S10 Plus

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 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.

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, carpet detection, 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.

- Carpet detection. The automatic carpet detection feature of robotic vacuum cleaners improves dry efficiency on low to medium pile carpets. When driving on carpet, the vacuum cleaner automatically increases the motor speed and suction power in order to achieve the proper cleaning result. As a rule, robot vacuum cleaners with support for this mode are equipped with a turbo brush and a capacious dust collector. It should be borne in mind that when cleaning carpets at high power, the battery life of the vacuum cleaner is reduced.

- 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.

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.

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.

— Ni-Cd (nickel-cadmium). The oldest of the options found in modern vacuum cleaners. It features high reliability, resistance to temperature extremes and good charging speed even with high capacity. The main disadvantage of this type of battery is a memory effect — a decrease in battery capacity if it is charged without being completely discharged. In addition, Ni-Cd batteries are considered environmentally unsafe. However, they are still widely used because of their low cost and decent performance.

— Ni-Mh (nickel-metal hydride). Further development and improvement of the nickel-cadmium batteries described above. While having the same basic advantages, Ni-Mh batteries are not affected by the memory effect and are safer to manufacture. Their disadvantages are the higher cost and somewhat shorter service life compared with the original Ni-Cd technology.

— Li-Ion (lithium-ion). A type of battery originally developed for use in portable devices. However, with the development of Li-Ion technology, it has been applied to other industries. The main advantage of such batteries is their high capacity with small dimensions and weight. It is also worth noting that they are not subject to the memory effect and can charge quite quickly. On the other hand, this option is not without its drawbacks — it is, first of all, sensitive to too low or elevated temperatures and a high price.

— Li-P...ol (lithium polymer). An improved version of the lithium-ion technology described above allows even more compact yet high-capacity batteries. The reverse side of these advantages is higher cost and increased sensitivity to low temperatures. However, for batteries used in vacuum cleaners, the latter is not critical.

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.
