Top 10 Backpack Sprayers
for December 2023

Weve used and reviewed several sprayers for weed, and while most worked as advertised, some had issues. This KIMO was the one we kept coming back to, thanks to its ease of use, its solid design, and its quality construction. It sprays straight, evenly, and at high pressure, and the 3-gallon tank has a fairly large capacity. The 4-inch wide mouth opening and molded-in gallon markers make it easy to precisely measure and fill the sprayer. The sprayers adjustable spray head has 23 and 43-inch extensions, which means you no longer have to struggle with small spraying heads, and its four-way 360-degree nozzle makes it easy to target weeds in different directions. The sprayers 2.0Ah battery lasts long, and we like that the sprayer comes with a battery, a charger, and a long wand. The only letdown is the batterys charge indicator light, which lights up red when the batterys power is at 50% and turns green when the battery is fully charged. Also, the sprayers battery compartment is top-loading, which means you have to remove the battery to get to the charge port. The sprayers design is practical, too, with a frame thats supported by a backpack and detachable strap pads. The sprayers pump is easy to operate and its lockable switch eliminates user fatigue. We like the sprayers design, which is durable, sturdy, and designed to be used by aging home users.

The VIVOSUN 4 Gallon Battery Powered Backpack Sprayer with Four Nozzles is a practical and easy to use sprayer, and it's particularly well suited for applications where you need a wide coverage area. This sprayer is most efficient at spraying and covering large areas, and it does a good job of keeping unwanted particles out of the water (the sprayer has an adjustable nozzle that allows you to control how much water comes out of each nozzle). We particularly like the rechargeable battery, which has 3-4 times the efficiency (and longer runtime) of regular pump-action sprayers. The rechargeable battery also eliminates the need for manual pumping, and it has a 4-gallon capacity, so it's large enough to cover large areas. This sprayer is heavier than other electric pump-action sprayers, but it feels great on your shoulder, and it's more comfortable to use than a hand pump. The sprayer is also easy to operate: simply turn the bar on the top to spray, and turn it to the left to stop. The sprayer has four different nozzles, and it's programmable, so you can control the coverage area. It also has a built-in filter, so it keeps unwanted particles out of the water. This sprayer is slightly more expensive than other electric pump-action sprayers, but it's durable, and it's well-designed and easy to use.

The FlowZone Storm 2.5 is a fantastic pressure washer for homeowners who want a powerful, yet lightweight, cordless unit that can reach great heights. Its performance is on par with higher-end, corded models, but because of the battery, the Storm 2.5's flow rate is much lower and its run time shorter. However, the Storm 2.5 is still plenty powerful for many applications, including cleaning your car, washing your siding and deck, and cleaning your patio or driveway. The included 18V lithium-ion battery provides up to 2.5 hours of continuous spraying and is rated for 1,000 charge cycles. The battery life is also much longer than that of cordless pressure washers, which typically run for half an hour or so before requiring a charge. The Storm 2.5 has a 5-position dial, which makes it easier to match the pressure to your cleaning task. The sprayer can reach up to 25-feet vertically or horizontally, making it a great unit for cleaning high walls, gutters, windows, and patio furniture. The Storm 2.5's plastic barrel is durable and lightweight, and its spray nozzle is adjustable to a number of angles. The sprayer also comes with two stainless steel nozzle attachments, a 0-degree and a 45-degree angle nozzle, which allow you to tackle a variety of cleaning jobs. The FlowZone Storm 2.5 is our favorite cordless pressure washer, and it's an excellent value, too.
