Ridgid 18V 4 Gallon Backpack Chemical Sprayer

Testing out the Ridgid 18V 4 Gallon Backpack Chemical Sprayer (R01501B) has been quite an experience. As a tool enthusiast who frequently handles lawn and garden maintenance, I was eager to see how this battery-powered sprayer would hold up against the more traditional pump sprayers. Here’s a detailed account of my time using this sprayer, highlighting its strengths and areas where it falls short.

Design and Build Quality

First, let's talk about the build quality. The sprayer features a robust HDPE (High-Density Polyethylene) tank, which promises durability and compatibility with a range of chemicals, including herbicides, insecticides, and fungicides. The tank is translucent, making it easy to monitor fluid levels, which is a small but appreciated detail.

The backpack design includes padded, adjustable shoulder straps and a hip harness, aimed at distributing the weight evenly. This is essential for a sprayer that can hold up to four gallons of liquid. However, I found the straps to be a mixed bag. While the padding is comfortable, the stitching on the straps left much to be desired. In my experience, the stitching felt weak and I had concerns about its longevity, especially when the tank is full.

Performance

Performance-wise, the sprayer delivers up to 105 gallons per charge, which is impressive. The adjustable flow rate knob and the ability to reach up to 105 PSI with a 37-foot spray distance are standout features. However, in practice, I found the sprayer’s performance to be somewhat inconsistent. The maximum spray distance I achieved was around 28-30 feet, falling short of the advertised 37 feet. Similarly, the pressure seemed to cap around 40-45 PSI, which is still decent but not quite what was promised.

The sprayer comes with four different nozzles: adjustable, flat fan, dual, and shower. This variety allows for a range of applications, from broad coverage to more targeted spraying. I found the flat fan nozzle particularly useful for large areas, while the adjustable nozzle provided flexibility for different tasks.

Battery Life

One of the most significant advantages of this sprayer is its battery life. Using the same 18V batteries as other Ridgid tools, it offers excellent runtime. During my testing, a 2.0 Ah battery lasted through multiple tanks of spraying without needing a recharge. This longevity is a game-changer for larger properties or extensive tasks, reducing downtime and increasing efficiency.

Usability

The usability of the sprayer is generally good, with a few caveats. The power switch and pressure dial are located on the back of the unit, which means you have to take the backpack off to adjust settings. This can be a bit inconvenient, especially if you need to make frequent adjustments. On the plus side, the sprayer is easy to fill and clean. The tank has clear gallon markers, and the lid opens and closes smoothly. There’s also a strainer to prevent debris from clogging the nozzles.

However, I did encounter a design flaw with the tank's pickup tube. The flat bottom design means that when the liquid level gets low, the sprayer starts sucking air, leading to intermittent spraying. This requires you to keep the tank at least one-third full to ensure consistent performance, which can be a bit wasteful and inconvenient.

Comfort and Ergonomics

In terms of comfort, the backpack design is generally effective. The padded shoulder straps distribute the weight well, making it easier to carry the sprayer for extended periods. However, the hip harness is not as comfortable as I’d hoped, and the overall weight of the unit, especially when filled to capacity, can be quite heavy. This is something to consider if you have a lot of ground to cover or if you’re not used to carrying heavy loads.

Durability

Durability is where this sprayer shows both its strengths and weaknesses. The tank and main components are solid and built to last. However, the weak stitching on the straps and the potential for leaks from the tank are concerning. In my use, I did not experience any leaks, but knowing that others have had issues makes me wary of the long-term reliability of this unit.

Final Thoughts

Overall, the Ridgid 18V 4 Gallon Backpack Chemical Sprayer offers a lot of conveniences, especially in terms of battery life and ease of use. The variety of nozzles and the adjustable flow rate knob provide flexibility for different tasks, and the durable tank material ensures compatibility with a range of chemicals.

However, the sprayer falls short in a few critical areas. The straps could be more robust, the maximum spray distance and pressure don’t quite meet the advertised specs, and the tank’s design could be improved to avoid sucking air when the liquid level is low. Additionally, the location of the power switch and pressure dial could be more user-friendly.

Would I recommend this sprayer? If you already own Ridgid tools and batteries and are looking for a battery-powered sprayer with good battery life and versatility, this could be a good addition to your toolkit. However, if durability and consistent performance are your top priorities, you might want to consider other options or wait for a potential design revision. The lifetime warranty does offer some peace of mind, but the initial quality control issues are hard to overlook.
