Operating mode

Operating modes provided in the design of the garden vacuum cleaner. Many models support more than one mode. Also note that, despite the common name "garden vacuum cleaners", not all units are capable of suction.

Blowing out. This mode can be called “vacuum cleaner in reverse”: the device generates a powerful air stream, which can be used, for example, to remove debris from hard-to-reach places, or “sweep” garden paths.

Suction. The classic mode of operation of the vacuum cleaner: drawing in air along with various debris that is sent to the bin. Suction is well suited for "uncomplicated" debris — leaves and small chips.

Shredding. This mode of operation is similar to the suction described above, however, the garbage drawn in by the vacuum cleaner is not immediately sent to the bin (or “to the exit”, into an external container), but is preliminarily crushed. The meaning of this function is twofold: firstly, due to crushing, the volume occupied by garbage is significantly reduced (see “Chopping factor”), and secondly, recycled leaves and branches can serve as fertilizer.

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.

Mulching ratio

The ratio of shredding debris provided by a vacuum cleaner with the appropriate mode of operation (see above).

This parameter shows how much the volume occupied by garbage decreases after passing through the grinder. For example, the value "8:1" corresponds to a reduction of 8 times. These figures, of course, are quite approximate, because. in fact, much depends on the type of waste, and in different cases, the indicators will also be different. For example, bulky large branches are “packed” very tightly, and soft leaves initially take up relatively little space, and for them the difference in volume before and after the chopper may be small. Nevertheless, the claimed values quite reliably describe the capabilities of the vacuum cleaner for processing the collected garbage.

Garden vacuum cleaners with a grinding ratio of 1:10 can be classified as average; lower rates are typical for relatively modest models, larger ones for advanced ones.

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").
