Comparison Husqvarna 580BTs vs Husqvarna 125BVx

The type determines primarily the way the vacuum cleaner is transported during operation and the associated application features.

— Manual. Garden vacuum cleaners designed to be carried directly in the hands — on the weight or on the shoulder strap (see below). It is inconvenient to carry a lot of weight in this way, so handheld models are quite light, relatively compact and, therefore, relatively low-power. However, this is not a disadvantage — rather, it is a specific feature of this class. But the key inconvenience when using handheld vacuum cleaners is the need to move a rather weighty structure during operation — this leads to rapid fatigue and makes it difficult to work on large areas. Therefore, most of these units belong to the entry level, designed mainly for simple work in small areas — for example, in the garden of a private house. On the other hand, hand-carrying has its advantages: a hand-held vacuum cleaner can be used in hard-to-reach places where a wheeled or communal one (see below) simply cannot go through. And to facilitate the work, special devices can be used, such as the mentioned shoulder straps or transport rollers (see below).

— Knapsack. Garden vacuum cleaners of this type in the working position are carried over the shoulders on straps, in the manner of a knapsack — hence the name. This method of...carrying is more convenient for transporting a large weight than the manual one described above: not only due to the fact that the main load falls on the straps of the backpack, but also due to the fact that during operation the vacuum cleaner hangs almost motionless behind the back, and the operator works only with pipe/hose. Thanks to this, knapsack vacuum cleaners are generally somewhat more powerful and performant than manual vacuum cleaners, while they retain such an advantage as high traffic.

— Wheeled. Garden vacuum cleaners designed for transportation on wheels. Outwardly, such models for the most part are characteristic carts resembling lawn mowers, which are complemented by vacuum hoses. This method of movement is provided for rather powerful units that are too heavy to be carried in the hands or in a knapsack way. Many wheeled vacuum cleaners are designed to be able to work while moving; most of them need to be pushed in front of the operator during operation, but there are also self-propelled models (see below).

— Communal. The most powerful and advanced variety of garden vacuum cleaners. The key features of utility models are the presence of a thick corrugated hose, as well as wheels; however, the latter, unlike the wheeled units described above, in this case are intended only for moving from one place of work to another — work on the move, usually, is not provided. The capabilities of communal vacuum cleaners are enough to clean entire streets or parks — hence the name. Note that such units, usually, do not have their own garbage bins — the garbage is supposed to be unloaded into the body of a car, trailer or other similar container.

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.

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.

Performance of the garden vacuum cleaner when working on suction (see "Operating mode").

As with blowing described above, this parameter primarily characterizes how large the area covers the vacuum cleaner when working: high performance means that the device captures more air and draws debris from a larger surface. But this indicator is weakly related to suction efficiency: the ability of a vacuum cleaner to “pull out” debris particles from cracks, thick grass, etc. depends primarily on speed characteristics, not performance.

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.

The volume of the garbage collector — a container for garbage — regularly supplied with a garden vacuum cleaner. The larger the bin, the more debris can fit inside and the less often you have to empty it during work. On the other hand, a capacious container has the appropriate dimensions, and when filled, it also weighs a lot, which can affect the ease of use of the vacuum cleaner (this is especially true for manual and backpack models, see "Type"). Therefore, manufacturers tend to choose bins for their products based on the overall level of the vacuum cleaner and the scale of work for which it is designed. And some units may not be equipped with complete containers at all — in the expectation that the user picks up such a container separately.

The volume of the garbage can can be approximately estimated, knowing that an ordinary household bucket holds about 10 – 12 liters. Thus, for example, a 35 liter container corresponds approximately to three standard buckets.

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.

The working volume of the internal combustion engine (see "Engine type") installed in the garden vacuum cleaner. With the same type of internal combustion engine (see above), more displacement usually means more power and higher fuel consumption. However, in general, the value of this parameter is more of a reference than practically significant — other indicators are more important for a garden vacuum cleaner, such as flow rate or performance (see above).
