Comparison Mova E10 vs Mova M1

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.

The nominal volume of the dust collector installed in the vacuum cleaner.

This indicator largely depends on the type of unit (see above). For example, in most handheld household models, the capacity does not exceed 0.5 L. The volume of the container in upright vacuum cleaners and robots can be somewhat larger — among the first variety there are quite a few models for 1 – 2 liters or even more, and among the second — by 0.6 – 1 liter and a little more. For conventional vacuum cleaners, the minimum figure is actually about 0.8 – 1 L; dust collectors for 1 – 2 L and 2 – 4 L are very popular in such devices; the maximum capacity is actually 4 – 6 liters — units of a similar layout, but with a larger capacity, are usually referred to as household ones. In turn, relatively small containers are occasionally found among workshop models. However, in vacuum cleaners of this type, the capacity is generally quite large — it can reach 26 – 50 liters or even more ; the same applies to industrial (construction) units.

In general, a larger dust container allows you to work longer without interruptions. On the other hand, a capacious container itself takes up more space and, accordingly, affects the size, weight and price. So when choosing th...is parameter, it is worth considering the actual features of the use of a vacuum cleaner. Here we can give such an example: for a full-scale cleaning of an average city apartment, a capacity of about 1 – 1.5 litres is required. Thus, say, a 4-litre bag allows you to carry out two such cleanings with sufficient efficiency without unloading the vacuum cleaner. There are more detailed recommendations regarding the optimal volume of the dust collector, including specific cleaning options. These recommendations can be found in special sources.

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

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

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

The automatic power control function is found mainly in robot vacuum cleaners. When driving onto the carpet, the vacuum cleaner automatically increases motor speed and suction power to achieve proper cleaning results. Usually robot vacuum cleaners that support this mode are equipped with a turbo brush and a spacious dust container. It must be taken into account that when cleaning carpets at high power, the battery life of the vacuum cleaner is reduced.

A method for limiting the processed space provided in a robot vacuum cleaner.

Another name for this feature is "virtual wall". Its general meaning is quite obvious: a “wall” (or several walls) allows you to limit the movement of the robot on the surface to be cleaned. It can be useful if cleaning needs to be done in a room without a door. Or if part of the floor is occupied by small items that do not need to be cleaned (for example, pieces of a puzzle being assembled). But the specific possibilities of such a restriction are directly related to how it is implemented. Note that the function is found mainly in middle-class robot vacuum cleaners and top models. Budget robotic "cleaners" often do not have the function of limiting the zones of the processed space - they do not have one.

Here are the main options found in modern robots:

— Laser sensor. A fairly popular option due to its simplicity, low cost, as well as simplicity and ease of use in fact. Usually, when installing the laser limiter, it is enough to put it on the floor and point it in the right direction. On the other hand, such devices are not well suited for creating complex borders. The classic format of the laser limiter is linear: a doorway or room is blocked by a direct beam, which is perceived by the robot as the boundary of the treated area. In addition, some models may also provide a circular mode, when the sensor forms a "forbidden zone" in...the form of a circle or sector of a certain diameter. This format of work allows to fence off the corners of rooms and small areas near the walls (a typical example is the location of a dog or cat bowl in the kitchen). If you need to create a border of a different, more specific shape, this will require several sensors at best (even though one limiter is usually supplied in the kit if supplied at all); and in the worst case, it will be completely impossible. It is also worth considering that the range of the laser in linear mode is usually limited to 3 – 4 metres; this is most often sufficient for residential premises and small offices. However, it may not be enough for a large space. And the emitters are usually powered by batteries or accumulators, the charge of which is limited.

— Magnetic tape. Limiter in the form of a tape made of magnetic material laid on the floor. Such a tape is spotted by a special sensor and is perceived by the robot as a border that cannot be crossed. For secure fixation, it is usually made self-adhesive, and the intensity of the magnetic field in most cases ensures effective operation through carpets and other similar coverings. One of the key advantages of such restraints is that almost any shape of the restricted zone can be formed from the sections of tape: the length of individual sections can be chosen at your discretion, and the maximum total length is limited only by the stock of tape at hand. In addition, this type of limiter does not require power. The disadvantages of this option include the complexity of laying in some conditions (for example, under a continuous carpet covering). In addition, at best, a very small amount of tape is included in the package; and many vacuum cleaners are not equipped with it at all, so you need to buy a magnetic tape additionally.

— Via the application. The most advanced way to limit cleaning: the boundaries of the working area are set on a smartphone or other gadget through an application that is also used for general control of the robot. Almost all models with this function also have the function of building a map of the premises (see below) — the finished map is displayed in the application, and on it the user can set the boundaries of the working area at will. The simplest version of such borders is separate straight lines. However, control applications often provide more extensive features: broken lines and polygons from individual segments, standard shapes (circle, oval, rectangle) and even the ability to draw a border by hand. Anyway, this method of restriction is extremely convenient and functional. However, robot vacuum cleaners with this capability are expensive, mainly due to the presence of a complex mapping system.

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.

The highest height of thresholds and various small obstacles that the robot cleaner can effectively overcome.

Most modern robots are able to effectively cope with obstacles with a height of 10 to 18 mm — this allows at least without problems to cross the edges of carpets, and small height differences at the boundaries of rooms (due to the difference in the type of coating), etc. But the models where the indicator is 20 mm or more are already referred to as robots capable of crossing high thresholds. However, even in such devices, the permissible height of obstacles does not exceed 30 mm. It is due to the fact that to overcome high obstacles, in particular, large wheels and high ground clearance are needed — and these features, in turn, increase the overall height of the robot, make it difficult to move under furniture and other low-lying objects, as well as reduce suction efficiency. On the other hand, even thin robots, whose height does not exceed 70 mm, can have very good crossing ability — for some of them, the maximum threshold height is about 25 mm.

— 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.
