Glossary
Max. air flow rate
The highest speed of the air stream given out by the vacuum cleaner. The higher this parameter, the stronger the thrust provided by the device, and the more efficiently it is able to pull or blow out debris particles from cracks and other hard-to-reach places (of course, if there is an appropriate operating mode — see above). At the same time, in most modern models, this figure exceeds 150 km/h — this is more than enough for work of small and medium complexity. Therefore, paying attention to a high flow rate makes sense only when choosing a powerful model for working in difficult conditions; we note that in the most “high-speed” vacuum cleaners, the indicators can exceed 400 km/h.
Air flow (blowing)
Performance of the garden vacuum cleaner when blowing (see "Operating mode").
This parameter determines the amount of air that the device distills through itself in a certain time. It should be noted that it depends not only on the speed of this air, but also on other parameters — for example, the diameter of the pipe. Therefore, two models with the same performance can noticeably differ in speed, and vice versa. You also need to keep in mind that the efficiency of "purging" bottlenecks with stuck debris does not depend on performance, but on the flow rate. On the other hand, good performance makes it easier to work on large areas, as allows you to simultaneously cover a large area with a jet of air.
Most modern garden vacuum cleaners in blowing mode provide up to 15 m / min; higher rates are typical mainly for professional models.

Motor power
The engine power of a garden vacuum cleaner, expressed in horsepower. This unit of power is considered somewhat obsolete and is mainly used for internal combustion engines (see "Engine type"), while in many cases the power figures in horsepower are also duplicated in watts. However, if there is no such clarification, it is quite simple to estimate the power in watts: 1 hp. approximately corresponds to 735 watts.
For more information about the value of engine power, see the paragraph of the same name below.

Motor power
The power of a garden vacuum motor, expressed in watts. This unit is currently the primary one; it is used for both electric and gasoline engines (see “Motor Type”).
The more powerful the motor, the more air the vacuum can move, the greater the speed it can impart to the airflow, and the more effectively the shredder operates (if one is present at all — see “Operating Mode”). At the same time, all these factors depend not only on power but also on many other design features; manufacturers select each motor to provide the vacuum with specific operating characteristics. Therefore, when choosing, it is worth looking primarily at the practical specifications (airflow speed, blowing and suction performance), while motor power is of secondary importance.

Noise level
The noise level generated by the vacuum cleaner during normal operation. The lower this indicator, the more comfortable it is to work with the unit, the less the operator gets tired; and high noise levels may require the use of protection (e.g. earmuffs).
When assessing the noise level, note that the decibel used to measure this level is a non-linear quantity. Therefore, it is easiest to evaluate specific values using comparative tables. Here is one of the variants of such a table (rather simplified):
— 60 dB — sound comparable to a TV at medium volume. From this value, the indicators of modern garden vacuum cleaners begin, because. this technique works quite loudly.
— 70 dB — to a truck at a distance of about 8 m;
— 80 dB — traffic noise on a busy street;
— 90 dB — freight train noise at a distance of 8 – 10 m;
— 100 dB — the noise of the demolition hammer;
— 110 dB — indoor rock concert

Weight
The total weight of the garden vacuum cleaner. Usually, this paragraph indicates the "net" weight of the unit — with an empty dust container (or even without a dust container at all), without fuel and oil (in models with an internal combustion engine, see "Engine type"), without a battery (in the corresponding devices, also see "Engine type"), etc. This parameter is important primarily for models designed to be carried "on oneself" — that is, hand-held and knapsack (see "Type").
