Comparison Dreame L10s Pro vs Dreame Bot L10 Pro

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 — ...href="/en/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 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 this 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 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 (se...e above), 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.

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.

Advanced models of robotic vacuum cleaners can havemulti-map memory. Thanks to this feature, when moving the robot to another floor, it does not need to reacquaint itself with the premises and build a new map. As a result, cleaning will be done faster and better.

Types of voice assistants supported by the robot vacuum cleaner.

As the name implies, this function allows you to control the robot using voice commands. However, we emphasize that in this case, we are not talking about the voice recognition system built into the vacuum cleaner but about compatibility with an external device on which the corresponding voice assistant is installed — a smartphone, tablet, smart speaker, etc. Thus, to use voice control, an additional device will inevitably be required; on the other hand, there are no problems with the search for such a device nowadays. And in itself, such a control method often turns out to be more convenient than a command from the remote control or searching for the desired option in the control application.

As for specific assistants, the most popular nowadays are (in alphabetical order) Amazon Alexa, Apple Siri, Google Assistant. And in robot vacuum cleaners, compatibility can be provided both with one of them and with several at once. The specific control functionality available through the voice assistant should be specified separately for each model. It is also worth paying attention to the supported languages: for Siri, the language must be selected in the settings, for the Google Assistant, automatic language recognition is available (some adjustment may be required), and in Alexa (as of early 2021) support for the Russian language is not provided at all.

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.
