How to Choose the Best Backpack Sprayer

Whether you’re watering or weeding a large garden or sealing your hardwood deck, you’ll probably benefit from having a backpack sprayer. These devices let you carry water and other liquids right on your back and dispense them with the pressure of a sprayer. They make all sorts of DIY jobs easy! Don’t know where to start? We’ve got you covered with our backpack sprayer buying guide! Let’s start with what you should know before you start shopping.

Best Backpack Sprayers

Power: Backpack sprayers are either manual or battery-operated. Manual sprayers will need to be pumped by hand to create enough pressure to spray. Battery-operated sprayers create that pressure for you. You only have to point and pull the trigger.

Best Backpack Sprayers

Hose length: This measurement, in feet, refers to the length of the hose that runs from the container to the spraying wand. A longer hose gives you more flexibility and can create more sprayer pressure to shoot a greater distance.

How to Choose the Best Backpack Sprayer

Capacity: This refers to how big the tank is. 4-gallon sprayers or smaller will be easy to carry when completely filled. You can spray for longer without refilling with a 4-gallon tank, making it the perfect size for home use.

Best Backpack Sprayers

Nozzle length: The length of the nozzle, or spraying wand, often determines how far the device can spray. There are attachments that spray different patterns or at different power levels. There are also nozzles that are better suited to certain tasks.

Best Backpack Sprayers

Size: Size can make all the difference for a backpack sprayer. Since it’s going to be on your back, you want to choose a device that fits your frame and isn’t too bulky for you. Find your perfect fit!

Product Intro Icon

Pieces: Most sprayers will come with accessories, including a battery if the sprayer is battery-powered. This can also include different nozzle head; usually, sprayers come with about 3 different attachments. These help you accomplish a variety of tasks.

Rainmaker Backpack Sprayer

Budget Pick
Our pick for the best cheap backpack sprayer is the Rainmaker. You are sure to get your money’s worth with this device because no job is too big for it to handle. It’s a manual sprayer, which means that it will need to be pumped regularly to keep the pressure going and allow the liquid to be sucked up into the wand. But it’s got an integrated filter to keep debris and larger chunks of any solution from getting sucked up into the wand and ruining it. The hose is an incredibly 4 feet long, giving you plenty of maneuverability with the wand. The nozzle at the tip of the wand can be changed to one of the four options that come with this sprayer. Different nozzles are better for different jobs, so you’ll always have the tools you need! You can lock the trigger ‘on’ so you don’t have to continually hold it down.

D.B. Smith Field King Sprayer

The Field King sprayer is pretty unique on our list. Instead of just building pressure, manually pumping the handle works internal paddles, to help the contents stay agitated. This is perfect for powder-based mixtures because they won’t have the opportunity to settle during your work. But what’s even better is the internal tank pressure. This sprayer generates an incredibly 150 psi inside the tank so that by the time the liquid gets to the wand, it is ready to spray for a long time! The pressure in this tank makes it a candidate for the best backpack weed sprayer! It’s easier than ever to get the mixture down onto those pesky, unwanted growths. It’s easy to replace or repair parts on this sprayer as well. Like any machine, it needs to be maintained. The gaskets and seals on this device are easy to take off and replace, so maintaining the sprayer is no hassle at all!
