  • Very high quality sprayer with very strong pressure and volume
Size: Self-Clean/8GL
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. ... show more

  • Just as good as the FlowZone sprayers
Size: Self-Clean/4GL
I've had this sprayer for a full 2 seasons and it has held up remarkably well. At first I thought I was settling with an inferior product compared to the FlowZone Typhoon (they were sold out everywhere back in early 2022 due to supply chain issues) but it's been the best $300 I've spent. I regularly spray fungicides, herbicides, insecticides, fertilizers, and humic acid it has significantly reduced fatigue and reduced the time per application. I use TeeJet spray nozzles (with adapter) which I can quickly change out depending on what I'm spraying and the type of wind conditions. I also accidently forgot to turn the pump off one time after cleaning the sprayer. So after the water slowly bleed out of the pump, it ran non-stop without water for 24 hours before I caught it. I thought I ruined the pump but it has ran flawlessly for a year. Pretty impressive if you ask me! BTW, this is the same exact sprayer as the one Yard Mastery sells. I'm pretty sure the sprayers from FlowZone, Yard Mastery, and Alientabi comes from the same manufacturer because many of the parts are identical (including the batteries). ... show more

  • High quality sprayer, worked better than I thought it would.
I like the build quality of this sprayer. I've used some sprayers over the years. Typically they are on the lower end and manual. I've look through Amazon find several brand, after comparison, I decided to buy this 3 gallon backsprayer by ALIENTABI. This "sprayer" has the same functionality without the need for manual pumping or pressurization from a water line. The spray performance. It pumps out more volume and at higher pressure than any of my other sprayers. The battery is also removable so I don't need to take the whole unit into my house to recharge. The water pressure is equivalent to what you get from a residential garden hose. The sprayer has a up fix block so that I can put the handle within it after I use it--space saving and convenience. This has worked perfectly for my needs. So far great product. If you are an outdoors person, this thing is great. Don't let the sprayer title limit this for weed and pest control. ... 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
