Comparison Rotex RVB16-B EcoClean vs Rotex RVB18-E

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 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 — 1500 – 1750 W..., 1750 – 2000 W and even more than 2000 W.

Suction power shows the actual force with which a vacuum cleaner lifts and draws in dirt from floors, carpets, furniture, and crevices. It is a more practical parameter than standard motor power, as some energy is lost in the filters, tube, container, bag, and nozzle. Around 150–250 W of suction power is often enough for smooth floors, while carpets, pet hair, and deeply embedded dust are better handled with approximately 350–500 W.

The type of power regulator provided in the design of the vacuum cleaner.

By itself , power adjustment allows you to adjust the operating mode to the current situation. For example, to clean a thick carpet, it is better to use a vacuum cleaner on full power, and on a delicate sofa or chair, it may be better to reduce the power. Types of power regulators are distinguished by location; options can be as follows:

— On body. The most popular option among modern vacuum cleaners. The main advantage of models with this design is that they do not require special hoses (unlike the units described below with adjustments on the handle). However, installation on the body is not very convenient for conventional vacuum cleaners (see "Type") — to change the power, you have to lean towards the body every time. However, for most users, it is not critical.

— On handle. The power regulator on the handle of the vacuum hose is convenient because the control is right at your fingertips, and you can change the power with just one movement of your finger, without bending over to the body. However, this convenience has a downside. So, some of these vacuum cleaners can only be fully used with special hoses; when installing a classic hose (without a regulator), the device, at best, will only work at full power, without adjustment, at worst, it will not turn on at all. A special hose is usually included...in the kit, but finding a replacement for it can be a quite troublesome (and costly) business. In other models, a wireless remote control is used, and its presence significantly affects the price of the unit.

— On body and handle. Vacuum cleaners combine both of the options described above. Usually, a hose with a regulator on the handle is supplied with such a unit. However, if necessary, you can install a regular hose and change the power with a switch on the body. Such control is the most versatile. Nevertheless, it is more expensive than each of the options described above.

The type of rigid tube supplied with the vacuum cleaner.

The most popular are telescopic tubes, extension tubes are much less common, and with some upright with handheld vacuum cleaners (see "Type"), tubes with a hinge are supplied in the kit (they are also "bendable" or "flex"). Here is a more detailed description of each option:

— Telescopic tube. Non-separable tube folded telescopically — by inserting one section into another. This option is the most convenient from the user's point of view. Firstly, such accessories are easy to unfold and fold — just press or slide the release key and pull or push the halves in the right direction. Secondly, many telescopic tubes are equipped with a mechanism that allows the structure to be unfolded incompletely. Thanks to this, you can adjust the length during the cleaning process (for example, reduce it to work in cramped conditions). Thirdly, the individual parts of such a tube can't be lost, which simplifies storage. The main disadvantage of this option is considered to be somewhat lower strength and reliability than that of extension tubes. However, this difference is noticeable only at high loads.

— Extension tubes. A tube consists of several parts connected during operation and disassembled for storage/transportation. Such designs are somewhat less convenient to use than telescopic ones, but they endure high loads much better and...last longer. Thus, extension tubes are rarely used in conventional vacuum cleaners, but they are popular in professional units — industrial, workshop, etc.

— Bendable tube. A tube has a hinge in the middle and can bend at an upward angle. It is a rather specific option, used in some vacuum cleaners of the "upright with handheld" type. This design makes it much easier to clean with such a vacuum cleaner under sofas, beds, tables, etc. By bending the tube, you can effectively treat such places without lowering the vacuum cleaner body to the floor. On the other hand, the hinge significantly complicates the design and increases its cost, and far from all users, these disadvantages are outweighed by the mentioned ease of use. That is why this type of pipe is extremely rare.
