What it is, how it works, how it works, selection criteria, popular models on the market. These and other questions will be addressed in this article.
What it is?
An electric sprayer is a device with a battery designed to destroy various pests and agricultural insects in summer cottages, country cottages and gardens.
In addition, it is an indispensable assistant in the issue of disinfection, fire extinguishing, washing windows and vehicles.
The question is how to choose an electric cordless sprayer so that it will serve you well for many years, and the wallet will hardly feel any changes. We will talk about this further.

The main task of the sprayer is the processing of vegetation in garden and house plots, in greenhouses and in open areas.
An electric cordless sprayer helps rid plants of pests, feed them with useful components and protect them from weeds.
Additional functions:
- disinfection of premises;
- processing of animals;
- washing the body of a car or two-wheeled transport;
- cleaning of window surfaces and walls;
- rapid elimination of the fire;
- arrangement of an autonomous shower room, etc.
The range of application is quite wide, the electronic accumulator sprayer will always come in handy on the farm. The presence of a power supply makes it more compact, provides mobility and versatility.

Design
Structurally, the electric sprayer consists of the following components:
- liquid tank with displacement from 5 to 20;
- electric pump;
- batteries made of lithium or lead;
- power supply charger;
- spray.
The main unit is a pump that creates high pressure and maintains it for the required time.
Some models can be equipped with an indicator indicating the battery charge level, various nozzles and other elements.
The plastic container is made of high quality material resistant to acid, alkali and other compounds.
The shape may be different and depends on the capacity of the tank. For small devices, it has the form of a cylinder. Products of a larger capacity are of a knapsack type and are designed to be worn on the shoulders.

The next important element is the diffuser. It comes in two types – telescopic and sliding. In its manufacture, plastic, brass or stainless steel is used. Thanks to the sliding design, you can work on the tops of trees and get to hard-to-reach areas.
The versatility of the electric sprayer is achieved by using different nozzles that provide spraying of the composition over a large area. In this case, the liquid can be dispersed in a fan, jet or cloud type.
Power is supplied from the mains and the battery, the charge of which is enough for a period of 1 to 8 hours.
How does an electric cordless sprayer work?
To pump out the liquid, pressure is needed, which is created using a pump (powered by a battery).
The system includes a relay that controls this parameter and gives a command to start or turn off the pump. Thanks to the well-coordinated work of the mechanism, the pressure necessary for the correct dosage and the elimination of overspending of the “working” composition is maintained in the container.
An equally important element of an electric sprayer is a valve that protects against overpressure.
A number of manufacturers complete the device with an indicator showing the battery charge level and a power change knob.
Knowing the charge level allows you to plan work and approximately understand how many hours the battery will last. Using the regulator, you can change the power of the device and, accordingly, the flow rate of the liquid.
Terms of purchase
There are a number of things to consider when buying an electric garden sprayer.
Let’s highlight the main ones:
- area of the treated area;
- the number of trees and bushes;
- frequency of use of the product;
- the need for additional accessories;
- price
For a small area, budget models with a small tank are suitable. If you need to process tall trees, you will need a model with a telescopic handle. With its help, you can reach the most remote areas. In this case, the length of the “rod” should be at least 2-2,5 meters.
The quality of processing depends on the characteristics of the tank and the nuances of its transportation. The most convenient option is to move the electric sprayer behind your back with the help of special belts. This is especially important if the volume of the container is more than 10 liters.
A necessary thing is a battery charging indicator. In its absence, a situation may arise when the electric garden sprayer fails at the most crucial moment. It should be noted that with increasing capacity, the duration of work also increases.
When choosing a battery, you need to consider that lithium products weigh less than lead ones. The advantage of lead-acid batteries is their unpretentiousness and the ability to work in a wide temperature range, including in frost.
The presence of a power regulator helps to fine-tune the dosage and flow rates of the working fluid when spraying plants. With a decrease in performance, the duration of operation without recharging also increases.
The price depends on the manufacturer, the quality of the device, equipment and a number of other factors. Many summer residents prefer domestic models due to the fact that they are easier to find components and cheaper to repair.
The products of foreign companies are more reliable, but more expensive to maintain. At the same time, domestic and foreign models are almost the same in terms of configuration. They often use pumps of the same brands. At the same time, the price of local products is lower.
Criterias of choice
When buying an electric garden sprayer with a battery, it is important to know the selection criteria.
Let’s highlight the basic parameters:
- Manufacturer. There are various manufacturers of sprayers on the market. The most popular are Foresta, Gerrard, Zirka, Belarusmash, Malorex, Forte, Lemira and others.
- Volume of the tank. The range includes devices with a displacement for containers from 0 to 70 liters and more.
- Type. There are manual, pump-action, gasoline and battery devices. The latter are the most attractive, because they can be used without additional fuel and electricity.
- The way to move. On sale you can find sprayers with the possibility of being carried on the shoulder, on a trolley or behind the back (knapsack). Manual models are also sold (the easiest and most affordable option).
- Spray distance. According to this criterion, electric sprayers show results from 1 to 16 meters. Before buying, you need to think about the methods of application and the types of plants to be treated.
- Engine power. In many online stores, products are filtered in two directions – up to and above 3 horsepower.
- Duration of work. This setting depends on the capacity of the battery. As we have already noted, electric sprayers with a battery can work from 1 hour to 5-6 hours or more.
- Weight. The weight of the device affects the ease of movement and use of the product. On average, this parameter is in the range from 2 to 10 kg.
- Sprayable drugs. There are two device options here. The first allow you to spray only liquids, and the second – powder and liquid formulations.
- tank material. On sale you can find sprayers with a capacity of steel, polyethylene and plastic.
- Fluid consumption. Depending on the model, the composition can be consumed at a rate of 1 to 6 liters per minute or more.
- Class. The considered devices are divided into two categories – household and professional. The first ones are suitable for home, garden, suburban area. If we are talking about business activities or the processing of large areas, it is better to buy a professional option.
- Additional features. The new models have useful options such as mist function, blower pump, blower option, droplet electrostatic charging, etc.
Another criterion that cannot be ignored is the price. This parameter depends on many factors, from the manufacturer to the set of additional functions.
Advantages and disadvantages
An electric sprayer, regardless of manufacturer and parameters, has advantages and disadvantages.
Pros:
