Compare Karcher WD 3 and WD 2
Karcher WD 3 and Karcher WD 2 vacuum cleaners have similar characteristics but differ in several key aspects. The WD 3 has greater suction power (200 W compared to 100 W for the WD 2) and a larger dust container capacity (17 L compared to 12 L), making it more efficient for cleaning large amounts of debris and construction materials. Users note that the WD 3 handles wet debris and construction dirt well; however, it is also considered noisy. Meanwhile, the WD 2 is lighter (4.5 kg compared to 5.5 kg for the WD 3) and has a lower noise level (77 dB compared to 75 dB for the WD 3), making it more convenient for home use. Nonetheless, many WD 2 users point out its instability and the fragility of the plastic, which could be a problem with intensive use. Overall, if you need a powerful vacuum cleaner for post-renovation cleaning, it's better to choose the WD 3, while the WD 2 is suitable for home needs.

Glossary
Suction power
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.
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 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 paramete...r, 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.

Blowing function
Ability of operation of the vacuum cleaner in the air blowing mode.
As the name suggests, it is the opposite of the standard suction mode. The air is not drawn into the hose but is forced out of it. This function significantly expands the functionality of the vacuum cleaner. In particular, it allows you to use the unit as a leaf blower for cleaning fallen leaves from the porch or paths in the yard, or for sweeping large debris into one pile. At the same time, blowing is especially useful where suction cannot be applied — like on paths covered with rubble. In addition, this mode can be useful for cleaning some hard-to-reach places — for example, radiators and other slots in the “hardware” of a computer: for several reasons, blowing out such places often turns out to be more effective than drawing in dirt.
Usually, to use this mode, it is enough to rearrange the hose from the main working port to the "purge" one.

Noise level
The noise level produced by the vacuum cleaner during operation. Usually, the value for normal operation at maximum engine power is indicated here. With less power, the loudness of the unit may be lower, but the key is precisely the maximum indicator.
Regarding specific numbers, keep in mind that the decibel used to measure the noise level is a non-linear quantity. Therefore, it is worth evaluating specific indicators using special comparative tables. In general, vacuum cleaners are quite noisy appliances; so in this case, models are considered quiet if this indicator does not exceed 65 dB — this is the level of a loud conversation between 2 – 3 people at a distance of 1 m. The quietest of these models give out only 40 dB — this is the average volume of a person’s speech in normal tones (and the minimum volume allowed for constant noise sources in living quarters during the day). For louder units, the comparison table looks like this:
— 66 – 70 dB — loud conversations between several groups of people at a distance of about 1 m;
— 71 – 75 dB — the volume of a cry or laughter in full voice at a distance of about 1 m;
— 76 – 80 dB — the volume of a mechanical alarm clock or the engine of an old truck;
— more than 80 dB — a very high noise level, exceeding the level of a loud scr...eam; when working with a vacuum cleaner having such specifications for a long time, it is highly desirable to use hearing protection.
Also note that the noise level largely depends on the engine power, as well as some other features (for example, it is strongly affected by the presence of an aquafilter — see "Dust collector"). At the same time, there is no hard connection here, and units with a similar set of specifications can differ markedly in actual loudness. In such cases, when choosing here, it is worth proceeding from the fact that a quieter vacuum cleaner will be more comfortable to use. However, it will most likely cost noticeably more.
