## Description

desertcart.com : ALIENTABI Backpack Sprayer 4 Gallon, Self-Cleaning Battery Powered Backpack Sprayer for Weeding, Cleaning, No Gear Limit, Variable Pressure : Patio, Lawn & Garden

Review: Early Impressions; a Great Sprayer - 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.
Review: Very high quality sprayer with very strong pressure and volume - I have been using a 5-gallon Solo backpack sprayer but needed something I could keep off of my not so healthy back. So, I got this cart sprayer. I was pleasantly surprised how well-built the sprayer is. All the components look to be top-notch. My Solo wand broke several times but it was cheap plastic and this is a stainless steel wand with a high-quality metal spray nozzle. The battery life looks to be very good, something like 6-8 tanks based on how it is going so far. In terms of performance it is very powerful -- it feels like it is several times more powerful than my backpack sprayer even though it is only rated at ~50% more psi. The spray is both finer and higher-volume than a backpack sprayer and so will cover 3-4 times faster. It seems to be somewhere between the hand-pump sprayers and the air-blast sprayers in terms of the rate and how fine the mist is. I have had no problems at all using the sprayer, just put a few parts together, charge the battery, and start spraying. The only thing I found a bit odd is the sprayer makes funny noises when it gets low, I think the motor is trying to clear out a potential clog. There is a special self-cleaning setting but I have not used it as it seems primarily useful if you are leaving chemical in the tank but want to flush out the pump/wand. I just flush out the whole thing when I am done. The hose length ends up being OK but I would prefer a longer hose. The supplier said they would be listing a hose extension in a few months and I plan on getting one. It would also be nice to have a wand extension option, it is working better than I thought on higher trees due to the high pressure but overall it would be easier to get the spray higher up with a wand extension.

## Questions & Answers

**Q: What does the self-cleaning mean?**
A: Self-cleaning: Through a special loop, the hose, sprayer parts and spray wand can be cleaned by external clean water without contact with the chemicals in the water tank.
It is especially suitable when you only spray half of the chemicals and plan to rest. You can keep the chemicals in the water tank, use self-cleaning to clean it up, and continue to use chemicals next time!

**Q: Does the pump run continuously when switched on, or only when spraying?**
A: Only when spraying. It shuts off when you release the trigger. If the tank runs empty, it will constantly run though so make sure to turn it off once the tank is empty.

**Q: Can sprayer be used to water plants without damaging them?**
A: This has an adjustable spray volume. It should work fine for watering plants.

**Q: Where can u just buy extra battery for sprayer**
A: You can order it from the company that makes it, but I can tell you the battery last a very long time. It can be used for several days for 3-5 hrs and want need to be charged.

### ⭐⭐⭐⭐ Unique features I haven't seen in other backpack sprayers. Some minor upgrades
*by R***E on December 30, 2022*

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.
