Moreover, the Field King boasts a dual-use pumping handle for both-handed operation so that you can flexibly change the hand to hold it when needed.

Best Backpack Sprayer For Gardeners Buying Guide

What Are Types Of Backpack Sprayers?


The diaphragm sprayer is more durable and easier to use than a piston model, yet it does not produce much pressure. Instead, this pump functions by an up-and-down pumping motion by a built-in diaphragm inside chemical tanks.

They are efficient and constructed out of materials to withstand acidic chemical solutions.


On the other hand, the piston pump typically generates higher pressure. However, it’s a sensitive mechanism, so you should use it with non-abrasive chemical solutions.

Piston models create a more steady flow rate. That said, they are more bulky and expensive than diaphragm pump sprayers. They also require more maintenance.

There are two garden sprayer types when it comes to how the liquid is pumped out from the chamber to the nozzle:

Battery Powered

Battery-powered backpack sprayers come in various sizes, styles, and materials to suit different functions or capacities. They are significantly popular for golf courses, lawn care companies, homeowners, and pest control services.

We highly recommend buying the best battery-powered backpack sprayers you can afford for various reasons.

This option lowers the demand for hand pumping, keeping you from getting tired. But, more importantly, the battery-powered model can put out an endless amount of solutions to ensure even applications.

You do not have to worry about PSI (Pounds Per Square Inch) or how much product is put out. So if the PSI varies, you can have a non-continuous application.

Battery-powered models have become more affordable these years. In addition, with the battery technology advancement, they have become incredibly lighter and can last longer.

Producers have developed battery-operated sprayers from scratches instead of converting manual backpack sprayers. The latest models feature better-designed pumps and improved microprocessor control technology.

Microprocessors can now monitor the sprayer’s battery to tell when the charging level is getting low and automatically shut down this unit.

Manual Sprayers

Various professional turf management companies still use this sprayer as it is more affordable and demands less maintenance than a battery-powered sprayer.

These sprayers last all day, making them ideal for professional settings where you cannot recharge a battery. Additionally, manual sprayers can be more durable as they do not have any electronics.

How To Choose The Best Backpack Sprayer

Garden Size And Storage

While you can use any type of sprayer in your garden, the size limits can speed up or slow down the gardening task you are doing.

A backpack sprayer with a small tank or short battery life can struggle with wide-open spaces, while an oversized model can be more challenging to use in a modest garden with a lot of architecture.

Choosing an appropriate size can provide a much better experience. However, remember the storage is essential as well.

If you end up puncturing the tank or hose, you will need to have it fixed, and improper storage can be one of the leading causes of this mishap. If your house does not have vast storage space, it is advisable to buy a more compact model.


Not every backpack sprayer is set up to do everything. However, some can provide specific chemical solutions like pesticides, fertilizer to the plants, or spraying in small or big areas.

Keep in mind which type of tool you want to buy before making the final decision, as you might end up damaging a sprayer if you utilize it in an unintended method.


Ensure the waist belt and shoulder straps coming with the backpack sprayer are well padded and can comfortably accommodate the tank’s weight. If the conventional straps aren’t adequate, check if the producer provides an upgraded version.

Backpack sprayers are great for lawn care and other uses.  In this video, this guy shows on battery powered backpack and one pump backpack sprayer:
