Features

  • Thoughtful Design with Hood: When you are spraying pesticides, chemicals, or gardening watering, in bad weather, you can protect your personal safety and prevent the spraying from external influences. At the same time, you can concentrate on the spraying range and reduce waste
  • Dual Speed Switch: Select the perfect spraying pressure for your battery pump sprayer at 36 psi or 65 psi with a flip of the switch. High-pressure gun with Viton seal plus extended threaded stainless-steel wand provides 0.46gp maximum pressure
  • Lasting Performance: Lithium-ion battery powered sprayer eliminates manual frustration. Spray for over two hours on one charge and over 26 feet. Simply remove the battery, charge it, and pop it back in
  • Double Waterproof: Our sprayer in lawn and garden is equipped with a front-facing 18V/2.6Ah Samsung lithium battery pack with indicator and overload protection. Fully sealed battery cover that clicks in for added water resistance
  • Customer Oriented: ALIENTABI is a customer-centric brand. Before the sprayer is sent out, the factory will conduct a series of quality inspections on the machine, including a water leakage test, so some products will have residual water stains inside the box, which will not affect the use. If you receive the goods and think there is a problem, get back to us

  • Versatile, easy to use battery backpack sprayer
Size: Inventor 7 Ultra Long&Enhance Pump 4Gal
The media could not be loaded. These ALIENTABI backpack comes with an 18V battery, 3 different nozzles, you can change the pressure from 65 psi or 95 psi just with a flip of the switch. Plus it makes even spot spraying the yard for dandelions an easier task. I compared this sprayer to my old 4 gallon backpack sprayer which was a pump type which wore me out way before finishing spraying, the shoulder straps on it are thicker and padded, so you really don’t feel the weight. With this sprayer, it’s ambidextrous. You can use either your right hand or your left hand to spray, as compared to my old one where you always had to pump with the left hand and spray with the right. Very tiring process with my old sprayer. I measured the longest distance that I could get with a full battery and the adjustable sprayer nozzle, you can spray up to 33 feet. Perfect for spraying those poison ivy vines that grow up the sides of our fence. On the video I used it to spray the flowers we have with water, also the flower beds where we are growing vegetables and peppermint, it’s excellent also if you don’t have a faucet near to put a hose, this makes it very easy, you can also use it to clean windows or my husband used it to clean the metal on the garage that he’s going to paint in one color. But I mostly bought it to fumigate my backyard this summer for fleas from the neighborhood straight cats and also for mosquitoes which during summer are bad. Overall this backpack sprayer is the best thing since sliced bread, and it turned my four or five times yearly back breaking chore into a quick, easy task. Versatile many ways to use it. 100% recommended. ... show more

  • Not for professional use
This thing worked great for about three weeks, diddnt spray as far as advertised but that’s ok. Today, it just quit working altogether..and I’m past the return window, don’t buy this thing if you are going to be using it every day.

  • Spray distance
Size: Inventor 7 Ultra Long&Enhance Pump 4Gal
The sprayer worked great, however the spray distance of 33’ is over rated. The sprayer did not reach out 33’ as advertised. The distance was more like 20’ to 25’. The life of the battery was great. I still showed a full charge even after power washing the whole house.

  • This backpack sprayer is a beast!
I currently own a few sprayers and I must say, this is by far the best sprayer of them all. When I took it out of the box I immediately noticed how well designed it was. The battery has an indicator of how much charge it holds which is super useful. The compartment where the battery is placed is water proofed with a rubber seal around the door which I think the little door will take force to break loose so opening and closing it numerous times won't affect it anytime soon. The battery life seems to be really good. I haven't had the sprayer for a long time, but I used it 3 times so far to spray 3,000 square feet of lawn and it still has plenty of charge so thats a win for me. I wanted a lithium ion but form factors are all unique to vendor. I use SAMSUNG and got to thinking that a charger/battery system is to expensive and the industry standard sealed lead acid battery can be purchased anywhere for cheap. The heaviest portion of the sprayer is the product and the slight extra weight of the battery is insignificant compared to the product. Long term cost wins and these batteries are proven performers. So, this is a really nice sprayer, but what about it's capability of spraying liquids? As I mentioned before, I own a few sprayers and this blows them out of the water! The stream can easily reach the top of my two story house from ground level. It is capable of putting down liquid lawn fertilizer with ease and faster. I like how far the wand extends which also comes in handy if you're spraying chemicals, keeping the mist spray as far away from you. Overall, I love this backpack sprayer. I don't think there's anything negative about it. It's well built and looks like they put lots of effort in the design. I definitely recommend it! ... show more

  • Works great
I purchased this specifically after it was referred to me by a professional pest control technician. It is high-quality and worth the money. It works very well.

  • best money spent, great tool
battery life is great. this saves me time and money when I don't have to fire up the hundred gallon nursery sprayer to solve a plant problem. 40 years experience in the nursery landscape trade

  • Great product half the price
I bought this looking for a sprayer similar to my Flow Zone, but since Flow Zone wanted to double in price I went looking elsewhere. I found this and it has been great. I use it daily as a pest professional. Uses same battery as a flow zone and same tank set up. Great value for the money. I actually like this the hi/lo switch better than the 5 setting switch on the Flow Zone. If you are in landscaping, pest control or someone that needs a heavy duty tank sprayer differently give this a try ... show more
