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.

ICE type

The type of gasoline internal combustion engine (see "Engine type") installed in the lawnmower.

— 2-stroke. With a similar volume (and, accordingly, dimensions and weight), two-stroke engines outperform four-stroke ones in terms of power. In addition, they are somewhat simpler in design, which has a positive effect on the price. On the other hand, such motors have a higher noise level and fuel consumption. In addition, not pure gasoline is used as fuel for them, but a mixture of gasoline and oil in a certain proportion, and failure to comply with this proportion leads either to the formation of fumes (if there is a lot of oil) or to increased wear (if there is little oil).

- 4-stroke. Four-stroke engines are more complex and more expensive than two-stroke ones, and also have slightly less power for the same working volume. At the same time, they produce less noise and are filled with petrol and oil separately rather than as a mixture.

Max. engine speed

The highest speed at which the vacuum cleaner engine is able to operate in normal mode.

Theoretically, faster motors are capable of delivering more solid performance; however, in fact, these characteristics depend on so many different design features that the engine speed is practically lost against the background of these features. Therefore, this moment, in fact, is purely reference (and partly promotional — impressive rpm numbers can at first glance give the impression of high power and performance; but this impression is often deceptive).

Fuel tank capacity

The volume of the fuel tank installed in a garden vacuum cleaner with a petrol engine (see "Engine type"). The more capacious the tank, the longer the unit is able to work without refueling (for more details, see "Fuel Consumption"). On the other hand, a large volume affects the dimensions and weight of the vacuum cleaner.

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").
