The attached shoulder straps are adjustable, wide, and feature extra padding for increased comfort when wearing the sprayer for a long time.



Although the item is advertised as having a collapsible handle, this feature doesn’t exist on this model. The storage space is not big enough for the wand so that this sprayer takes more space to deposit.

Although not a product fault per se, the customer support provided by this company could use improvement, especially when it comes to returning faulty or used sprayers.

Our Comprehensive Buying Guide


Gardening and looking after your plants can take a lot of time, especially since you need to constantly water them, add fertilizers, and protect them from pests. One easy way to do all these is to invest in a backpack power sprayer that can be filled with all the substances you need and can help you finish all the tasks faster.

However, since there are thousands of products available on the market, choosing the right one for your needs might take some time. Check out our comprehensive buying guide and find out some of the most important features your sprayer should include.



Tank size

The size of the tank is one of the most important things to look for in any type of product, whether it’s a cheap backpack sprayer or a more expensive one. Most devices designed for commercial use feature a four-gallon tank, enough to cover the area of a small vegetable garden, lawn or backyard.

On the other hand, products designed for industrial use will require bigger tanks of 20+ gallons as they need to cover a significantly larger surface.

No matter the size of the tank you choose, make sure it is translucent to easily see when it requires a refill. Also, look for items made of sturdy materials and with secure locks that won’t leak the chemicals out, causing rashes, irritations or even burns on your skin.


Pump sprayers or battery-operated models?

Most sprayers with small-sized tanks of 2-4 gallons will require you to push a pump to release the substances through a hose. These products are the most popular because they are used to cover medium surfaces.

However, sprayers used for industrial purposes or needed to cover a large area will require the help of a battery that makes pumping easier, without causing hand fatigue when operating them. Usually, the battery is rechargeable and lasts for a couple of years, depending on how often you use the sprayer.


Back support

We don’t call them backpack sprayers for nothing, right? Make sure to also take into account the way these sprayers attach to your body. Look for products with wide, padded shoulder straps that will support the pressure of a full tank without causing back or neck problems. All extra straps, hooks and loops, zippers or other security elements are welcomed, especially when the tank is full and heavy.



Nozzles, hoses, and pockets for storing all accessories are key elements of a good sprayer. They help regulate the pressure and allow you to choose between a fine mist or a full stream, depending on the type of surface you need to spray.

It would be best if all these accessories were stored together with the sprayer to occupy less space and deliver a compact design. Thus, try opting for sprayers that feature special pockets and compartments for batteries, hoses, and nozzles.


Other features to consider

We should start by saying that all tanks should come with a good filtration system that prevents dirt and debris from getting inside and altering the quality of pesticides or fertilizers. Pick products that feature a double or triple filtering system or those that come with a detachable filter than can be cleaned when clogged. Otherwise, you will spend a lot of money on constantly replacing filters.

A large tank opening is preferred because it helps you clean the accessory faster and easier, as well as fill it without spilling.

Last but not least, professionals might also need to take into account the total distance that the sprayer can reach when operated vertically or horizontally. We recommend searching for a thorough backpack sprayer review if you still have doubts regarding how to choose the perfect product for your garden’s needs.



Frequently Asked Questions


Q: What should I look for when buying a backpack sprayer?

As we already mentioned in our buying guide, picking the right backpack sprayer depends on your needs and expectations.

Based on the size of the land you wish to fertilize or clean from pests, you need to know the difference between a commercial backpack sprayer and a pro backpack sprayer. The former usually feature smaller tanks and are manually operated, while the latter use batteries and can spread more product on a larger surface.

You also want your backpack to be comfortable to carry on, so you should look for products with adjustable padded shoulder straps. The wider the straps, the less pressure will be put on your back and spine.

A good filtration system is necessary if you want to prevent clogging during use and changing the pump too often. Lastly, look for a backpack garden sprayer that is made of durable and sturdy materials that won’t corrode when getting in contact with chemical compounds.



Q: How far can a backpack sprayer spray?

This question doesn’t have a simple answer as it depends on the type of product you use. It is more difficult to maintain the travel speed, pressure, and spraying distance at optimum levels when you’re dealing with a manual sprayer, as opposed to handling a battery powered backpack sprayer.

Generally speaking, most manual sprayers reach a distance of 10-20 feet when the product works in excellent conditions. Other more powerful items can spray up to a distance of 30-35 feet, sometimes even more.

However, the total spraying distance is only relevant when you’re covering large surfaces of land. The majority of commercial sprayers available on the market will reach up to 20-25 feet, enough to cover your garden, lawn, and backyard. And, since wind also plays an important role when spraying your lawn or garden, you will easily reach every piece of land you need to fertilize or keep away from pests with a regular backpack sprayer.


Q: How do you calibrate a backpack sprayer?

When it comes to manually operated sprayers, uniform distribution of sprays could prove difficult, even with training and regular calibration. It’s not always easy to keep pressure, spraying distance, and speed at optimum levels when you’re handling a manual sprayer. By comparison, a motorized sprayer will move at a preset speed and have a set boom width.

There are different ways to calibrate a manual sprayer, and here is what you should do. First, measure and mark off an area that’s equal to 1,000 square feet (20 x 50 feet).

Secondly, you need to make sure the sprayer is properly cleaned and rinsed. Add water to the tank, spray the area, and then measure the amount of water that was left in the tank. The difference between the amount of water in the tank before and after spraying is the right amount of product you will need to spray 1,000 square feet of land.

The last step of calibration is to compare the measured application rate with the recommendation on the pesticide or fertilizer label. Generally speaking, there shouldn’t be a difference bigger than 5% between the measured rate and the recommended rate. You can make adjustments to perfectly calibrate your sprayer by changing the walking speed.
