Power adjustment

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.

Battery run 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.

USB charging

The USB charging allows you to charge the vacuum cleaner from a classic 5 V phone charger. A USB cable is included for this purpose, but the adapter itself will have to be taken from old stocks or purchased additionally. Anyway, nothing prevents you from charging your gadget from a power bank battery, laptop, PC, etc.

Charging station

A feature found in battery-powered vacuum cleaners - most robots, as well as some upright models (see "Type").

The charging station combines the functions of a charger and a storage device. Its specific design may be different. Robots are equipped with a floor docking station; most of these devices can remember the location of the station and, if necessary, return to it on their own — for recharging or at the end of the program. In other types of vacuum cleaners, the charging station usually is wall-mounted. The vacuum cleaner hangs on it while connecting to a power source to charge the battery. Some of the wall attachments can also be used to charge the battery removed from the vacuum cleaner. However, we emphasize that traditional chargers that do not provide for hanging on the wall and fixing the entire vacuum cleaner are not considered charging stations. Less common are floor-standing charging stations for upright vacuum cleaners and desktop docking stations for charging portable (handheld) models.

In any case, this function is almost standard for robots, but upright and handheld household vacuum cleaners equipped with a charging station, in general, are quite advanced and expensive devices.

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.
