Hose length
The length of the hose supplied with the sprayer.
The longer the hose, the farther the spray tube can be reached without moving the sprayer itself. However, this is true mainly for wheeled and universal sprayers (see "Carrying type"). In shoulder-mounted units, the hose is usually selected in such a way that it is enough to comfortably hold the tube in your hand, and this parameter in such models most often does not exceed 150 cm.
It is also worth considering that long hoses can be quite bulky; however, this disadvantage is often eliminated by the use of spiral hoses, which are stretched to their full length only when necessary.
Spray wand length
The length of the spray tube supplied with the sprayer.
A long tube, on the one hand, allows you to reach far without leaving your seat and without using stools, ladders, etc.; on the other hand, it is not very manoeuvrable and can be inconvenient when working in tight spaces. When choosing, it is worth proceeding from the optimal compromise between these characteristics. For example, a large tube length (up to 2 m in some models) is useful when processing fruit trees, but for a greenhouse it is better to choose a shorter sprayer. It is also worth considering that some sprayers use telescopic (sliding) tubes, the length of which can be adjusted as needed; in such cases, the unfolded size of the atomizer is usually indicated.
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.
Replaceable nozzles
The ability to change nozzles — sprayer working nozzles.
Different nozzles differ primarily in terms of spraying distance and width of the plume, as well as the degree of spraying (particle size). In addition, specific nozzles can be used in sprayers — for example, for working with powder. Replacement nozzles are usually included in the delivery, but this point (as well as the range of nozzles) is still worth clarifying separately.
Weight
The total weight of the sprayer. Specified without taking into account the liquid or powder in the working tank; at the same time, for battery models (see “Type”), usually, the weight is given with a complete battery, and for gasoline models, on the contrary, “dry” weight, without fuel in the tank.
