Nice sprayer. Lightweight and easy to use. Battery lasts long enough for several tanks.

Other than possibly receiving a bad sprayer from the factory, I'm not sure why some people are having difficulty with it. The tube in the container has a good filter on it. The included hose is very long. The trigger has both a spray and lock on it to prevent accidental spraying. The pump is adequate, spraying a good 10 feet when the nozzle is set to stream instead of mist. The rechargeable battery is more than enough to power the pump. The box included extra rubber seals/washers (note these are not needed upon initial assembly). Putting the thing together couldn't be easier. I quickly sprayed an area with herbicide that is difficult for me to get to, so adding in 2' weeds/grass makes it even more fun to get into. With this sprayer I was able to cover the entire area with the herbicide. Once dead I'll remove the grass/weeds. After spraying I emptied the tank, filled with water and ran the pump until clear water was coming out of the spray nozzle. I shut off the pump then drained the hose by holding the tank up high and opening the spray wand trigger allowing the water to drain out. The sprayer is now waiting in the garage for its next job, most likely pesticide around the base of my house. The only complaints I have are that the power switch on the battery pack is a little finicky to get to turn on and off, it works it's just touchy. The carry strap is a little shorter than I would like, but it works. I would like to see some sort of snap in holder on the side of the tank for the wand. It would also be nice to either have a power button on the wand or a pressure sensor on the pump so it would shut off when not in use instead of having to reach for the power switch on the pump itself. I like that the tank includes a manual pump so it can be used like a regular sprayer if absolutely needed. Compared to any of the other powered sprayers, I like this one the best. If I had to replace the pump on this sprayer I most likely could if I looked for the right pump. On most others the pump is built in, so if it dies you either have to disassemble the sprayer to get to the pump or just toss the thing and try another brand. If the pump dies on this sprayer, I can fairly easily replace it. The only thing that would make this powered sprayer easier to use is if someone else would spray for me! Good product, good price. Properly clean and maintain it and I don't see how this could ever be a bad buy.

I changed my review to 4 stars based on customer service from seller and the fact that the replacement sprayer works perfectly. Had my initial sprayer worked like the replacement, I would have rated 5 stars.

First Review
The unit I received was junk. First off, the pump hardly sprays. The pump states it flows at 0.8 liters per minute which means it should pump a gallon of liquid in under 5 minutes. It took almost 30 minutes to pump 1 gallon. If I pump the manual pump several times while the electric pump is running, it sprays well. However, this only lasts for about 15 seconds before going back to hardly pumping. The whole reason for the electric pump is to not have to pump manually. The other problem is when I try to pump up the sprayer manually, it leaks badly between the large black cap and the orange body. Very disappointing. I will be returning.

I'll start off with the bad: the instructions. According to the instructions, the nozzle and extension tube should have already been together, but they weren't. I just got the separate pieces with a bag full of different sized O-rings and seals. Absolutely no instructions on how to put it all together because it assumed it was already together. Luckily, I've done stuff like that a lot before, and it's fairly easy to figure out how it goes together.

There was only one other issue. I filled up the tank and turned it on. The pump was working, but it wasn't pressurizing enough to spray anything out. But I saw someone else on here say to manually pump it up in the beginning, and the battery powered pump will keep it going from there. So I did that, and it worked. After manually pumping it in the beginning, the electric pump kept it working until the tank was empty.

After all of that, I have to say this thing is awesome! It sprayed really well, and the size of the tank was the perfect size to spray around both sides of my privacy fence, around my whole house and external garage, and along the retention wall that is along one whole side of my property. The tank ran out exactly when I was finishing up everything that needed done. I was happy to not have to ever manually pump it again after the beginning. I'm really happy with this purchase.

So no operations manual, and boy did I need one. So I'm just going to tell you what I did to get mine working like a champ.

1)First get a better spray nozzle. Cheap easy fix.
2) I used the included seals and sealed both the air check valve and the hose going from the canister to the pump. The seals are included but you'll have to play around and figure out which ones fit best in which area. You want this air tight and it is easy to do if you put the right seals in.

3) now heres where I needed a manual. I filled it up and then pumped it like 10 to 15 times or so then your ready to go, but wait. If you switch on the pump now the pump will stop and it will only spray until the pressure runs out. So instead pump it up Push the trigger and then while holding the trigger turn on the pump switch and boom worked like a charm.

I hope this helps someone. It took a crappy experience with what seemed to be a cheap powered sprayer to the Cadillac of sprayers.
