Comparison Bosch ALS 30 06008A1100 vs Stiga SBL 2600

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.

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.

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.

Power of the garden vacuum cleaner motor, expressed in watts. This unit is by far the main one, it is used for both electric and gasoline engines (see "Engine type").

The more powerful the motor — the more air the vacuum cleaner is able to pass through itself, the greater the speed it is able to give the air flow and the more efficient the chopper (if there is one at all — see "Operating mode"). At the same time, all these moments depend not only on power, but also on many other design features; and manufacturers select each motor in such a way as to provide the vacuum cleaner with certain performance characteristics. Therefore, when choosing, it is worth looking primarily at practical characteristics (flow rate, blowing and suction performance), and engine power is of secondary importance.

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).

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

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").
