Solo Vs. Stihl Backpack Sprayers (Key Differences & Which Is Best?)  

Solo and Stihl produce backpack sprayers which, on the surface, are very similar and even their branding is pretty similar. There are, however, some key differences when you investigate in more detail.  

Both Solo and Stihl make sprayers that are multi-purpose, but Stihl has more powerful models which are better suited for larger jobs. Solo backpack sprayers are definitely more durable, but Stihl sprayers have a slightly longer warranty to protect your investment. Stihl backpack sprayers tend to be larger because they have more power, and even though Solo and Stihl are similarly priced, Solo sprayers are a little more affordable.  

There are a couple of other factors to consider when buying a backpack sprayer that might impact the brand you choose: 

1. Piston Vs. Diaphragm 

Both Solo and Stihl offer both piston and diaphragm pumps in their backpack sprayers. This gives you two different options for how you pump the liquid from the tank, so it sprays in the way you want.  

Piston mechanisms can reach up to 90 PSI which makes the droplets of liquid smaller. This allows them to reach a lot further and means you can generate a mist which is useful if you want the liquid to rise up. Piston sprayers have a lot more impact, though, so they’ll need to be repaired or replaced more often.  

Diaphragm sprayers are slightly different. They use a wide, flat internal diaphragm which is pumped up and down to create pressure. This generates about 60 PSI which means the droplets are larger and easier to control and direct. This type of mechanism is a lot less strain on your device and helps to improve the longevity of the sprayer.  

Diaphragm sprayers are best if you’re spraying down, like if you’re targeting weeds, and piston sprayers are better if you want to create a mist that travels further, like if you’re spraying insecticide in a field. Both brands offer sprayers with either, so it really depends on what job you need them to do. 

2. Manual Vs. Motorized 

Motorized backpack sprayers are slightly newer but are becoming more common. They typically use either gasoline or a battery back to power them and remove the need to pump any of the liquid manually. This is better for larger jobs and gives you more power with minimal effort. These sprayers are usually more expensive, though, and cost more to run.  

Manual sprayers rely solely on your pumping motion to pressurize the liquid. This typically gives you a shorter reach because there’s less power, but it’s often the best option for smaller jobs.  

Stihl produces a better range of motorized backpack sprayers, so if that’s what you need, then they're the better brand for you.  

3. Tank Capacity 

Both Stihl and Solo have large tanks which allow you to carry a lot more liquid in one go. This makes them easier to fill and clean but can make the overall device heavier when it’s filled up. There really isn’t much in it on this one, but Solo makes some backpack sprayers with very large tanks, which can be useful.  

4. PSI (pounds per square inch) 

PSI stands for Pounds per square inch (PSI), and it shows you how much liquid a backpack sprayer can fire through its nozzle. Essentially, it shows the pressure generated and gives you an indication of how far the liquid will go. Typically, the higher the pressure, the finer the droplets, and if you apply enough pressure, it’s more like a fine mist.   

If you have too much pressure, then the sprayer will be hard to handle, but too little, and the spray won’t be even. Typically, you want a backpack sprayer that can reach 70 PSI and but Solo and Stihl do this comfortably. Stihl offers models which offer more PSI, particularly with their motorized range.   

5. Power & Speed  

The power and speed of a backpack sprayer help you determine how long it will take to get a job done. Both Solo and Stihl offer some decent power, but Stihl versions are slightly more powerful. This makes them the better choice for larger jobs where you need to get it done quickly.  

6. Ease Of Use 

Backpack sprayers need to be user-friendly and should be simple for anyone to use. Both Stihl and Solo understand that, and none of their sprayers are particularly complicated to use. However, some Stihl models have a few extra features which can be intimidating at first, and Solo backpack sprayers are probably better for beginners.  

7. Price 

Both Stihl and Solo are in the low/mid-range when it comes to backpack sprayers, and there isn’t much separating them in terms of price. Solo sprayers are generally more affordable and produce durable products, which make them pretty good value for money. Stihl costs a little more, so you might opt for a Solo if you have a tight budget.   

8. Overall

Overall, Stihl offers more power and has larger sprayers for larger jobs. However, Solo backpack sprayers have large tanks, and the superior build quality makes them the preferred choice for most professionals. Stihl backpack sprayers are more likely to be used by amateurs or DIYers.
