  • Early Impressions; a Great Sprayer
Size: Self-Clean/4GL
I did a lot of research when replacing my old hand pump backpack sprayer with a battery powered one. One of the features that helped me decide on this sprayer was the self-cleaning feature. I have a large pond and need to spray algicides in order to keep the surface clean. That leads me to the second reason I chose this sprayer. It sprays at least 30 feet horizontally depending on wind and chemicals being sprayed. When I received the sprayer, I was immediately impressed with the manner in which it was packaged. After some minor assembly and charging the battery, it was ready for use. I ran a tank of plain water in it first to see the different spray patterns of the three included tips. After that, I mixed up some algicide and put the sprayer to use. I was a little concerned at first that the straps did not include straps across the stomach. After properly adjusting the straps, I realized that a strap across the stomach was not necessary. It does have a strap with buckle across the chest. The unit is very comfortable on the back and the on/off/variable pressure dial is easy to reach. When I finished spraying, I rinsed the tank since I used the entire mixture minus just a very small amount in the bottom of the tank. I poured a bucket of water and attached the self-cleaning pickup hose. I flipped the diverter valve to clean and pumped plain water through the pump, hose, and nozzle. It doesn't get any easier than this. The battery has a lot of charge left in it so there is no need to charge it after each use. Given all of the choices out there, I am really glad I picked this one. Absolutely no leaks, a strong performer, and not at all uncomfortable on the back. This is a solid piece of equipment. I am in high hopes it gives me years of trouble-free service. ... show more

  • very much worth the cost - a really good sprayer - just buy it
This is a really nice professional-quality powered sprayer. 2.5 gallons is plenty for me to carry on my back. The pump is well up to the task. The wand is long enough that you can squirt weed spray at the base of plants without a lot of grief. When you get it, don’t make the same mistake I did. It has a big door in the back for the battery. So I looked for a big battery. I thought something was wrong and had the first one replaced by Amazon. The second one had the same small battery. It looks small, but has plenty of charge to handle the load in the sprayer. I again apologize to the manufacturer. This is far superior to carrying a pump-up sprayer. It’s very well made. The price is right. The yellow weed spraying nozzle puts down a mist of spray on the target weeds, and it still has some range to spraying. Also, being powered, cleans up quickly. ... show more

  • Unique features I haven't seen in other backpack sprayers. Some minor upgrades
Size: Self-Clean/4GL
I have looked over a number of backback sprayers, and knew that I wanted a battery powered one so that it can spray more evenly. I have used pump style sprayers before and once the pressure gets lower I tend to overspray or underspray areas, so I knew a battery powered one would keep a constant stream (hopefully). This product has features that I haven't seen on any other battery powered backpack sprayers, such as the pressure washer style spray attachment which can use the same nozzles as pressure washers. Other backpack sprayers have weak plastic nozzles pointed at weird angles. The motor isn't loud and I can dial in the pressure I want which is also a unique and useful feature. I thought I would really like the rinse feature, but I will probably never use it only because it seems like it would be easier to attach a water hose to the tank at a lower pressure and then use the sprayer to cycle through the water coming from the hose to rinse it out. Though the rinse feature can also be used to transfer fluids and you may have to own it to know what I mean. The manual states this which is where I got that idea from. The description makes it sound like is has a super duper smartphone battery, when in fact its just a regular power tool battery, and a low voltage one at that. It is only 18.5 volts, and perhaps it has to be lower in order for the tank not to be emptied immediately at full power. They could probably greatly increase their sales and lower their price if they used the same batteries as the Black N Decker 20V power tools which probably all of us already own and sell it as (tool only). I read backpack sprayer reviews stating how heavy they are when filled with liquid, but I have no problem with it. I suppose all of those years carrying heavy books in my backpack and walking to school paid off. So if they ever release a newer version in the future, I would suggest that the sprayer hose can unscrew from both ends and use Black N Decker style batteries. I will use this to spray products on my large lawn that do not work with hose sprayers. I thought about getting a tow sprayer to use with my riding mower, but I don't have anywhere to put it so this smaller backpack can be placed on the shelf in my garage. UPDATE I have used this about four times already to spray weed killer on my lawn and it has worked perfectly. I like how its almost like a weaker version of a 120V pressure washer. The first time I filled it all the way up and didn't have any problem with the weight and the shoulder pads are very thick to absorb any discomfort. The next few times I used it, I didn't fill it all the way up as I didn't need as much and its a lot lighter then (obviously) for those who say it may be too heavy when full. ... show more

  • No leaks
Easy to assemble out of the box. No leaks, comfy padding. Came slightly wet inside which they said was expected from the QC per the FAQ. Charge indicator on battery itself does not work (no lights) but other than that, no other issues so far.

  • Great Customer Service
I had an issue with battery performance and seller did a good job to make it right. If you have issues you may need to consistently follow up with the seller to resolve. Product works good but it a bit heavy and cumbersome to put on by yourself when full. Recommend having someone help put the pack on your back. ... show more

Size: Self-Clean/8GL
more powerful than i expected. i could almost reach the top of my 40ft pecan trees; which is more than enough to kill those walnut worms because they congregate lower at night.

  • An Easy To Handle Backpack Sprayer
At 2.5 gallons the weight on your back is manageable and carrying the load is convenient. What I like about this sprayer is the batter is in the back rather than at the bottom of the sprayer. My last sprayer had the battery at the bottom and once the battery got wet and failed and the other time the motor got wet and failed. If you don't need huge quantities of spray this is a good choice. ... show more
