Backpack Sprayer Buying Guide

This section will be very useful if you are looking for a backpack sprayer. We have outlined the criteria that we used to determine what makes the best backpack sprayer. However, keep in mind that different users have different needs and expectations. So, make your own decision by considering the following factors.

Type of Sprayer

There are two types of backpack sprayers: manual and motorized. Manual backpack sprayers are less expensive, while motorized backpack sprayers are more expensive. This is obvious: manual backpack sprayers do not require a motor.

Motorized sprayers have powerful batteries that make using them easier. However, if convenience is your main priority, you might want to invest in a motorized unit. The only drawback is that they require more maintenance.

Backpack sprayers come in two types of pumps- piston-powered and diaphragm. Piston-powered backpack sprayers are more powerful and can be used with most chemicals. However, they are less expensive than diaphragm-powered backpack sprayers. Diaphragm backpack sprayers are not as powerful as piston-powered sprayers. Still, they can be used with harsh chemicals without damaging the pump.

There are different types of pumps that you can choose from. Diaphragm pumps are resistant to chemicals and can create high pressure quickly. However, they require more maintenance. If you need high pressures, go for a diaphragm unit. If you plan to do overhead spraying, consider a piston pump.

Backpack Sprayer Design and Fit

When choosing a backpack sprayer, it is important to find one that is comfortable. This is especially important because you will be carrying it around for a while. Look for backpacks with straps that are adjustable and padded. The tanks should also fit well, so you don't get tired from carrying them.

Backpack sprayers with padded waists and shoulder and chest straps provide more comfort, especially when used for long hours. It is important to get an excellently fitting sprayer for comfort and safety.

Sprayer Capacity and Pressure

Your garden and yard are different from your neighbor's garden. Choose the backpack sprayer capacity and pressure depending on how big your yard is and how you plan to use it. Professional grade sprayers have a high pressure of up to 150psi, while medium-grade has a pressure of up to 95psi.

Nozzle Type

There are three types of nozzles available for backpack sprayers: flat fan, cone sprays, and steam nozzles. You should be careful when selecting the type of your nozzle as it determines how your backpack sprayer will work best.

Also, consider how simple it is to change the nozzle if necessary. Follow the manufacturer's instructions for all types and adjust the patterns accordingly.

Weight and Durability of the Backpack Sprayer

High-quality backpack sprayers usually have tanks that are made from high-density polyethylene. They also have UV protectors to ensure the tank is durable and safe.

However, it is important that you check on the materials manufacturers use in engineering the units. A backpack sprayer might be heavy or lightweight, depending on the materials used in its making.

You will have to think about what is more important to you. Is it comfort or durability? The frequency of use of the sprayer should also be taken into consideration.

Backpack Sprayer Maintenance

You will agree that backpack sprayers are long-term investments. If you want your sprayer to last long, you must take care of it. The way you take care of it can vary depending on the manufacturer. Still, some guidelines apply to all backpack sprayers.

You can do a few things to keep your backpack sprayer working well. For example, you should clean it after every use. You should also use an anti-freeze substance when storing the unit during the cold seasons. And you should lubricate the O-rings and seals occasionally, especially if you use the unit frequently.

What Is the Purpose of a Backpack Sprayer?

Landscaping isn't necessary. Backpack sprayers feature larger tanks than handheld ones.

Heavy containers are harder to carry. Versatile backpack sprayers. Know your limits to maximize performance and safety.

Backpack herbicide sprayers are utilized in the yard, garden, and home—well-killed weeds. Soil enhancers, fertilizers, and pesticides are also employed.

Backpack sprayers avoid ice, concrete, and wood. Cheap, easy-to-use, portable backpack sprayers. 15 to 20 pounds, depending on tank size. Hard-to-reach spots, tiny acreages, and chores larger tow-behind equipment can't reach.

The 4-gallon size is popular. The spraying area determines sprayer size. The capacity of tow-behind sprayers is greater.

How To Use A Backpack Sprayer

Utilizing your backpack sprayer boosts application efficiency, ensures your safety, and prolongs the life of the equipment.

Before spraying, it is essential to keep in mind the following:

  • Actual usage instructions are identical regardless of the liquid utilized (herbicides, pesticides, water, or liquid nutrients). I recommend against using the same backpack sprayer to apply RoundUp and any other product. You should avoid the possibility of cross-contamination.
  • Carefully read the product label and wear the necessary safety equipment.
  • Before filling the tank, ensure that it has been calibrated with water.

Step 1: If necessary, assemble the unit by inserting the pump handle into its proper location, attaching the spray wand to the spray gun, and securing the shoulder straps.

Step 2: Preparing the bucket test liquid combination. Pesticides, herbicides, and insecticides are blended with water. When combining chemicals, read labels and work where spills won't harm plants or water sources. These chemicals are highly concentrated, so a small quantity goes a long way; don't mix them more vital than the label indicates.

Step 3: After combining and diluting the chemical, slowly pour it into the tank. Ensure that no chemicals drip onto yourself or the ground when pouring.

Step 4: Place the sprayer on your back and tighten all of the straps until they are secure and snug.

Step 5: 10 to 15 pumps are made. Maintain tank pressure by pumping every 5 seconds. If you don't do this, you'll have to prime your sprayer whenever the pressure dips. OR Ensure your model's battery is ultimately charged.

Step 6: You're all set to go! Aim your wand at the target area and squeeze the trigger. There are many more steps in spraying, but I will not discuss them in this article.

Step 7: After spraying, disassemble the container and clean each component. Finally, store or recharge the backpack sprayer. Ultraviolet radiation destroys plastic sprayers in the sun.

Safety Tips

When working with chemicals, safety must take precedence.

  • Inspect the complete pump for damage, cracked hoses, and leaks before use.
  • Wear essential personal protective equipment (PPE), such as eye protection, chemical-resistant gloves, clothing to cover exposed flesh on the arms and legs, and a respirator.
  • Always mix chemicals according to the instructions on their labels.
  • Be vigilant when walking, watching where you step to prevent potential dangers.
  • While wearing the backpack, bend at the knees to maintain the sprayer upright.
  • Spray chemicals away from yourself, and never walk through an area that has just been sprayed.
  • Exclude pets and other individuals from the area until the application has dried.
  • To reduce drift, keep the spray wand low and avoid applying in windy conditions.
  • Wash your hands thoroughly after completing a task, using the restroom, or consuming food or drink.

Type Of Backpack Sprayers

Backpack sprayers vary by pump type and pump power. The diaphragm pump and piston pump are sprayer dispensing systems. Pumps are battery or hand-powered.


Diaphragm pumps are more robust and user-friendly than piston pumps, although they produce less pressure. This pump's diaphragm pumps up and down inside the chemical tank. They're effective and can withstand acidic chemical solutions.


A piston pump sprayer provides more pressure, but its delicate mechanism should only be used with nonabrasive liquids.

Piston pumps provide a more steady flow rate than diaphragm pumps but are more expensive and bulky. They demand more maintenance.

Battery Powered

Battery-powered backpack sprayers come in various types, materials, and sizes. Golf courses, pest treatment, lawn care services, and homeowners use them more often.

I propose buying the best battery-powered backpack sprayer within your budget.

First, Hand-pump-free backpack sprayers are battery- and motor-powered. A battery-powered sprayer is reliable—better application without lbs/in2 (PSI). Variable PSI means inconsistent application.

Second, Battery-powered devices have gotten cheaper. Battery technology has improved, making them lighter and longer-lasting.

Third, Manufacturers are designing battery-powered sprayers instead of manual ones. Better microprocessors and pumps are in new electric sprayers. When the battery gets too low, microprocessors shut down the device.

Manual Sprayers

Pros utilize manual sprayers. Batteries cost more to maintain than pumps. They don't lose energy, so they last all day, which is essential in professional settings where batteries can't be recharged. They may be more challenging without gadgets.

How To Determine The Right One To Buy

How do you choose amongst many items (with so many reviews)? This guide will help you select the best backpack sprayer.

What are backpack sprayers most suited for? 

Chemical sprayers are handheld. Tractors or ATVs pull sprayers—backpack nozzles. Choose wisely. Large properties require a backpack sprayer. Backpack sprayers reduce stress and fatigue.

Arms and shoulders hurt from one-arm carrying—energy-efficient backpack sprayers. A backpack sprayer is great for properties with fences, steep hills, uneven land, and trees. Small acres, spot treatments, or inaccessible areas use these sprayers.

Capacity. Large-capacity backpack sprayers reduce refilling time.

What is your budget?

Battery sprayers cost twice as much as hand-powered sprayers (but the difference is shrinking), while gas-powered ones cost 3-5 times as much as a pump backpack sprayer.

A battery-powered sprayer speeds up the application because the operator doesn't have to pump—newer models last hours without charging.

Will it be used for personal or commercial applications?

Commercial uses may require a hand pump backpack sprayer. They're easier to maintain and don't need batteries.

A battery-powered backpack will make quick work of your property and won't need continual charging.

How To Maintain Your Sprayer

You've researched and found the right backpack sprayer. You want to keep your sprayer running like new after investing money.

  • Before using, read the handbook thoroughly.
  • Always check hoses and connections.
  • Always use gloves, goggles, PPE, and proper gear when spraying.
  • Never use caustics, acids, hot water, or flammable liquids.
  • Do not pressurize with an air compressor since this can cause injury-causing burst parts.
  • Never lift your backpack sprayer by the wand, shut-off valve, or hose.
  • A sprayer near the open flame is dangerous.
  • Don't modify your sprayer.
  • Always utilize OEM parts for repairs.
  • Kid- and pet-proof.
  • Never leave your sprayer in the sun since UV rays might cause harm.

Proper cleaning is crucial to sprayer maintenance. After each usage, drain the tank of any chemicals. Before care and when not in use, release all pressure.

Always empty, dry, and clean tank, pump, extensions, and hose. If you don't, sprayer components could explode when pressurized. Forcible part ejection or high-pressure liquid discharge might cause serious injury.

Difference Between Cheap And Expensive Models

For every requirement and budget, there's a suitable backpack sprayer.

Cheaper variants have smaller tanks with thinner walls and lower-quality polyethylene. The diaphragm pumps will reduce the flow rate and PSI. Most will be manual, requiring you to hand-pressurize the tank while spraying.

Pricier models have better, more durable components, larger tanks, and nozzles. They have a piston to raise PSI and maintain flow rate.

Cheaper battery-powered machines last longer and recharge faster. Costlier units usually have more comfortable straps and an ergonomic design.


A backpack sprayer is a very important gardening tool. It can be used to apply many different types of products. It can be hard to decide which product is best, but this gives you a few good options.

You should check the recommendations to find a backpack sprayer that meets your needs. Finding a good backpack sprayer can be hard, but our guide will make the process easier.
