Rainmaker Backpack Sprayer


While it’s not the strongest sprayer on the market, and it lacks in design compared to many of the others on our list, the Rainmaker is perfect as a cheap sprayer which will allow people with small yards to take care of weeds and pests without breaking the bank.

This budget sprayer even has a lock on feature. It’s not going to throw things the length of your driveway, but it’s perfect for handling weed in cracks and spot applications in your yard.

It’s obviously a budget option, but it costs about half of what the competition does and if it suits your need you’ll be pleasantly surprised. There’s a few problems with the build quality, including rubber O-rings instead of more modern materials so you’ll need to be careful with chemical selection but it’ll handle the usual suspects with ease.

If you’re looking for a budget sprayer for smaller applications, then you’ve found your mark. For heavy-duty applications or if you’re a stickler for perfection, give it a pass and go with something of higher-quality.

  • Cheap
  • Easily pumped
  • Holds pressure well
  • Four foot hose
  • Lock on trigger
  • Lower build-quality

My 4 Son’s 4-Gallon Battery Powered Backpack Sprayer

4-Gallon Battery Powered Backpack

Coming in with a fantastic, motorized sprayer My 4 Son’s has exactly what you need, if you’re willing to spend the extra money. Without a doubt this is solidly the best of our picks, coming with a powerful motor that’s powered by lead-acid batteries.

While not as advanced as Li-ion batteries, they do provide a longer use time at the expense of being slower to charge. Thankfully, their long life will keep you spraying for more than the duration of most jobs and you can just place them back on the charger.

We’re talking about a 60 psi pump which blows away the competition, and the company who produces them has so much faith in their sprayer that they actually include their personal cell phone number right on the product.

If you’ll only settle for the best of the best, then go with this sprayer. You won’t be let down, but you’ll definitely be spending some extra money to make sure you’ve got the superior product.

  • Professional quality
  • Tons of nozzles
  • Long lasting battery
  • Steel wand

What to Consider Before Buying a Backpack Sprayer

To be perfectly honest, not every yard needs a backpack sprayer. If you’re perfectly content weeding away in the summer heat and just want to spray down the cracks in your driveway then you’re not likely to find much use for one.

If you have a considerable amount of ground to cover, however, and want to be able to specifically target weeds in your yard then they can be a godsend. The ability to quickly and easily use herbicides on trouble areas is a bonus that a lot of people really desire.

Of course, others are looking for a sprayer for something a little bit more specialized. If you’re looking to find something which can handle a task like staining a deck then you’ll want a different tool than someone who just has a weed problem.

Keep in mind your intended use before you make a final decision, this way you’ll be able to make sure that you get just the right product for what you need.

What to Look For In Your Backyard Sprayer

Sprayers come in a surprising amount of configurations depending on what you’re planning on doing with them. Little variations can mean a big difference between something that’s easy and almost a joy to use and something which you only lug out reluctantly.

Whatever you’re looking to do, keep all of the following in mind when you’re on the lookout for your new companion.

Pump Type

There are a couple of different pump types which are available for your sprayer. Piston pumps are easy to use but not suitable for all applications. They’ll also prime faster, making it quicker to get to work with your sprayer. They really shouldn’t be used with all types of pesticides and herbicides however, especially if you’re planning on using anything abrasive.

Diaphragm pumps, on the other hand, are a easier to repair and more durable with a wide variety of chemicals. You’ll want to look into your preferred chemical before you decide to use one with a piston pump, but diaphragm pumps should be able to handle most things as long as the rest of the tank will hold up to it.

Motorized or Manual

For smaller yards you can save both money and weight by going with a manual pump. They’re easy to use, easier to cart around, and you probably won’t have to stop and reprime more than a couple of times for the average application.

On the other hand, a motorized sprayer can definitely save you a lot of effort for bigger applications. If you’ve got a lot of ground to cover, look for a motorized backpack sprayer with a locking trigger. You’ll be glad you did, but it’s really not necessary for spot applications.

Motorized sprayers also offer much higher amounts of pressure, which is pretty much essential for some applications such as pesticides where you want to get things spread thinly over a large area.

For spot killing weeds, however, a manual pump provides more than enough to burn up troublesome and invasive plants.


You’ll want to make sure that you have some good straps for carting the backpack around. While a minimalistic harness can save you some money, a good setup can make even a heavy sprayer seem quite light once it’s strapped on.

This is especially important if you’re covering a wide area, and it makes things a lot safer since there’s less risk of you falling over while cutting down those weeds.

The Wand

The wand’s materials and construction is of the utmost importance. In fact, it might be more important than the tank itself since it will be the part most prone to leaking or having trouble during normal usage.

Look for wands made of stainless steel or other metals, along with brass fittings for the best results. You may also want to see if the sprayer that you’re considering is compatible with TeeJet heads, these aftermarket parts can give you a wide range of different patterns depending on the usage you’re looking for.

In general, even for wide usage you want something that doesn’t leak since a lot of chemicals can be quite noxious when they’re applied.

Maintaining Your Sprayer

Backpack sprayers do require a bit of maintenance in order to ensure that you get the most longevity out of them.

  • Cleaning your sprayer at the end of every session is an essential practice to making sure that you get the longest lifespan out of it. To make things easier, make sure that you calculate the amount of chemical that you have to use during your sessions to make sure there’s minimal waste at the end of the job.
  • Lubricate your o-rings and seals at least annually. Make sure that you follow the directions that come with your sprayer, since different seals may require different methods of lubrication.
  • In cold climates, winterizing the tank is a must. If things freeze in the winter where you live, you’ll want to add some antifreeze to the tank. Propylene glycol based antifreezes are preferred, since they’re less toxic when you need to empty them out during the spring.

For the most part, as long as you follow the above guidelines plus anything extra the manufacturer recommends, you’ll be in good hands. Just make sure you do it, since a malfunctioning sprayer is no fun at all.
