Design

The design of the sprayer primarily determines how it is transported during operation. According to this parameter, manual, shoulder, wheeled and combined types of construction are distinguished, here are the features of each option:

— Manual. The most compact type of sprayers: during operation, the device can be held entirely with one hand. Such models usually look like a tank in the form of a bottle or can with a volume of up to 3 – 3.5 liters (and more often up to 2 liters), over which a spray gun is installed. A pump or lever drive is used for operation (see "Type"), although there are also battery options; and 360° spraying can be provided for convenience in hard-to-reach areas (see below). Anyway, hand sprayers are mainly designed for small jobs that do not require larger and heavier devices. In addition, such a sprayer may be the best choice for cramped conditions, where it is impossible to turn around with a shoulder-mounted and even more so wheeled unit.

— Shoulder. Sprayers of the "middle weight category", designed to be carried using a shoulder strap. Usually such a unit is worn on both shoulders, in the manner of a backpack; the exception is pump-action models (for more details, see "Type"). Anyway, this method of transportation is very practical and versatile. It is perfect even for fairly powerful and, as a result, massive sprayers — the only...exceptions are the heaviest models with a tank volume of more than 30 liters. Actually, most modern atomizers are made just shoulder-mounted.

— Wheeled. Sprayers equipped with wheels and moved only in this way. This method of movement is the only one available for the heaviest and most performant units with large tanks that are too heavy to be carried on the shoulders. However, there are also comparatively small and light sprayers with wheels — they are mainly intended for cases where high power is not needed, but shoulder-mounted models are not suitable for one reason or another (for example, if health problems prevent the user from carrying heavy loads ).

— Shoulder / wheeled. Models that allow transportation by any of the two methods described above are optional. In fact, these are shoulder models, complemented by wheels (or the ability to install wheels); this design provides additional convenience and versatility. For example, when working in open areas, it is more convenient to carry the sprayer on your shoulders, and in a greenhouse with narrow passages in which you can’t turn around with a “backpack” on your back, you can put the device on wheels and roll it along. However, such features are not required so often, while they affect the overall cost of the device. Therefore, this option has not received much distribution.

Productivity (liquid)

Maximum performance of the sprayer when working with liquid; Please note that in pump (see "Type of pumping") and battery (see "Type") models, the actual performance may decrease as the air supply or battery charge is exhausted.

High performance allows you to quickly process large areas; moreover, it is often combined with a good spraying distance (see below). On the other hand, such models require fairly large tanks — or they often have to be refilled; neither one nor the other contributes to the convenience of work. In addition, over-capacity is even more undesirable than under-capacity: a low-capacity sprayer will just take longer to process, and a too-capacity sprayer can ruin the job by “overdosing” the chemical. Therefore, it makes sense to use high-performance devices only for specific tasks.

Detailed data on optimal performance values for different situations can be found in special sources.

Max. pressure

The maximum operating pressure of the sprayer.

High pressure allows to achieve good spraying performance and range, however, actual performance can vary with units with the same pressure. Therefore, in general, the indicator is for reference (the lion's share of models has a pressure of 3 bar and 4 bar, and it is only possible to compare different models by it approximately. When choosing, it makes sense to focus on more practical characteristics — performance, range, etc.

Telescopic wand

Availability of a folding telescopic tube in a set of delivery of a sprayer.

The length of such a tube can be adjusted within certain limits, adjusting it to the specifics of the situation. For example, in cramped conditions, a large length is not needed, but when processing tall trees, on the contrary, it is very convenient. Specific adjustment options may be different: in some models, you can choose only one of the two extreme positions (fully folded or fully unfolded), while others allow you to fix the handset in intermediate positions.

Wand material

The material from which the complete spray tube of the sprayer is made.

— Plastic. The key advantage of plastic over other materials used for spray wands is its low cost. In addition, this material is chemically inert and does not corrode, and also has a low weight. On the other hand, the rigidity of the plastic is not very high, which is why such tubes tend to bend, sometimes even under their own weight.

— Aluminium. Aluminium alloys combine good strength and lightness, such a tube is easy to work with, and it takes quite a strong blow or pressure to bend it. On the other hand, aluminium is expensive.

— Brass. In addition to strength and reliability (including resistance to bending), brass is notable for its excellent resistance to corrosion. The disadvantages of such tubes are the high price, as well as the rather large weight.

- Stainless steel. "Stainless steel" is notable primarily for its high strength and rigidity, which is superior to other materials, despite the fact that this material is relatively inexpensive. However, such tubes weigh much more than aluminium or plastic ones.

- Copper. According to the main operational properties, copper pipes are similar to brass ones: they are strong, reliable and durable. On the other hand, such tubes are relatively expensive and do not have fundamental advantages over the same "stainless steel". Therefore, this option is rarely found.

Voltage

Nominal voltage of the battery used in the battery sprayer (see "Type").

In general, a higher voltage is needed to provide high power. At the same time, the characteristics of models with the same battery voltage may differ markedly. Therefore, in fact, this parameter may be required to search for a replacement battery rather than to select a sprayer and compare it with other models.

It should be noted that modern sprayers usually use batteries of standard voltage — 6 V, 12 V or 18 V. At the same time, most models are 12-volt, 6 V is found mainly in low-cost devices of a small volume, and 18 V is found in powerful professional equipment.

Capacity

Capacity of the complete battery in the battery sprayer (see "Type").

A higher capacity allows you to work longer without recharging, but this is true only “ceteris paribus” — the actual energy consumption (and therefore battery life) depends on the performance, range and some other characteristics of the sprayer. Therefore, only devices with similar indicators can be compared by this parameter, and it is easier to evaluate battery life by directly claimed operating time (see below). Also, larger batteries tend to weigh more and cost more. Therefore, manufacturers usually choose the battery capacity according to the features of a particular model — in order, on the one hand, to ensure good battery life, and on the other hand, not to greatly increase the weight and price.

Operating time

Time of continuous operation of the battery sprayer (see "Type") on one battery charge. The actual operating time may differ slightly from the claimed one due to the specifics of a particular situation, however, these differences are usually not very large, and this indicator can be used to evaluate not only theoretical, but also practical indicators of battery life.

Charge indicator

Indicator showing the battery level in the battery sprayer (see "Type"). Usually, it is used both during the operation of the unit and when charging the battery. Most often, the role of the indicator is played by the simplest voltmeter, which allows you to assess the state of the battery by changing its voltage.
