Review: Appears to be high quality - So far, great. This unit is an improvement over the Petra 4-gallon sprayer that only gave me problems. I have used this unit to spray 8 tanks of herbicide so it’s new. What I find so well designed with this sprayer is that it shuts off the pump when the spraying stops. Another design that appeals to me is the built-in bottom stand that helps in stability when I have the unit on my zero turn mower between my legs. It doesn’t tip over. I also ordered and received the 4.2amp battery so now I can spray for a long time. I need the long spray time because I live on a large acreage.
Review: Outstanding sprayer! - I've been using my sprayer for about 3 weeks now. Just yesterday and today I sprayed 6 acres of avocado orchard where weeds were growing between the rows and between trees. I pretty much worked non-stop each day for 6 hours and the battery never showed any signs of weakening. I do believe they are correct when they say it'll spray 50- gallons on one charge. It doesn't leak, it's very quiet and it's comfortable with it's wide straps and harness. Here's the thing: I am not spraying continuously, I'm spraying individual weeds but at times I'll spray for upwards of 5-6 seconds when I encounter a cluster of weeds. The sprayer kept-up just fine but after 4-5 seconds you will notice a reduction in pressure and it starts 'falling-off', after 8-10 seconds you're at half-power. Of course, this will vary depending which spray head you use. Now let me tell you about my awesome modification! Since you no longer have to pump the sprayer, I decided to convert mine into a dual-sprayer unit! I cut the hose about 6 inches coming out of the tank and then went to Home Depot and bought a plastic/nylon Tee fitting. I then got some fuel-injection clamps (not band clamps), these clamps are smooth and let you really cinch down on the hose. I took another hose and sprayer and now I have a sprayer in each hand! This proved to be incredibly more production and faster working through the orchard. You can also bring the sprayers together to double-saturate a weed as well. Did the sprayer keep-up with having TWO sprayers going? Yes, it did but if both sprayers were going for more then 5-6 seconds I did notice the pressure reduced and I wasn't get as much a mist/spray but instead more streaming. Still, double-sprayer is the way to go, I'm surprised they don't offer this already.

## Questions & Answers

**Q: Just received and used it today, it's great but can the pressure be adjusted down? It's very powerful and atomizing the spray so I'm getting drift**
A: Adjust the nozzle or put different nozzle on. Atomizing is preferred for some tree or shrub spraying, but you need to adjust the nozzle. Good pressure is great.

**Q: What all brand batteries work in it? Whats the biggest battery compatible?**
A: Takes the same battery as the Ortho Sprayer.

**Q: Does anyone else have a problem with having 4 gallons of product but tbe sprayer will only spray 3 gsllons and won't spray the last gallon ?**
A: I have the same issue.  I believe it's because the internal pick up tube is too high i also need to see if i can have my harness replaced either way still lasts me about 2 house treatments maybe 3 depending on square footage.  I'm actually looking to order a second one as mine is finally a year old.  Still works after the abuse of arizona residential services.

**Q: ¿Trae cargador para la bateria?**
A: Si, trae cargador para la bateria. Gracias

### ⭐ Quality Control Issues
*by L***S on March 16, 2026*

Ordered one and the pump would not prime. I returned that unit and received a replacement, that pump wouldn’t prime either. I verified this was not a me issue by following the instructions to prime and also watching the video to confirm. I then called customer support and they couldn’t offer much help over the phone. Returning the replacement unit and buying a different brand.
