An adjustable hip harness assists with weight distribution, relieving burden from the user's shoulders. Multiple nozzle tips are included for versatility in both application rates and patterns and can be stored on the included nozzle clip. Equipped with a comfort grip handle and lock-on mechanism, this shut-off system can be easily operated with heavy-duty work gloves.

    • Good sprayer
One of the best sprayers I've owned, the straps and well made and work great don't know about the adapters the nozzle does all I need but the black one is handy when you want to know where you left off, it is pricey but it comes with battery and charger and it is dewalt

    • Good quality, and not too heavy.
Reading reviews before I purchased this, I was a little concerned because people said it was heavy. I have used both Solo and Echo hand pump backpack sprayers over the years as a Private Applicator. Honestly, I can’t say it was much heavier than either of those. I started by putting it on the back of my golf cart and driving around. It is top heavy and would fall forward if I hit a bump. Next I tried walking with it and it was comfortable and worked well. I used a DeWalt 8AH battery. I sprayed a total of 21 gallons of herbicide (5 batches and a clean-up) and there were still 2 of the 3 green lights on indicating it had only used 1/3 of the battery. I’m impressed with it and think I made a great purchase. ... show more

    • Perfect for your Lawn Care business
I have had this for a week now. As a professional landscape/lawncare business owner, this is the perfect tool! Can spray 4000sqft of herbicide in a few minutes and refill and spray again. The single 2ah battery lasts a long time (don’t know the exact because I used one all day when needed and didn’t drop a single bar). If you are contemplating getting away from the hand pump, here is your answer. If you are like me and already have a bunch of 4 and 5ah batteries, you are set for days worth of spraying without ever having to charge a battery ... show more

    • Works great
Love this sprayer... works very well! Runs more tanks of water than you're willing to pick up and run around with on a 5AH battery... has great pressure and probably 20-25' vertical spray. Its very easy to use, just a little heavy when completely full, but comfortable once you have it strapped on.

    • Really Nice Sprayer
Love this sprayer. For my purposes all of the correct spray tips are included. Batter lasts long enough to completely cover my 100,00 Square Feet of Bermuda.

    • fantastic sprayer.
This thing is AWESOME !!!!!! I can't tell you how much I love this sprayer. I have been spraying Permethrin around the house to kill off the bugs. This works great with little effort. When you fill it to 4 gallons it gets a bit heavy (think of it as a workout with a backpack :). It does have waist straps so that helps out a lot. With 4 gallons, I'm able to go around my whole house and spray to kill of the bugs. Works great. I would definitely buy it again in a heartbeat especially since many of my powertools are from DeWalt and use the same battery packs. Side note. When you get it, you might need to prime it. Getting a garden hose and blasting water into the vent (as suggested) worked REALLY well. After that, it works every time without priming it. ... show more

    • Doesn’t work
Dewalt does not manufacture or service this item. Besides the fact that it does not work the seller won’t take responsibility for their product. They are very difficult to communicate with, ask for the same information multiple times, and generally just throw up enough barriers until you give up. I own dozens of good DeWalt tools, but this is not one of them. Don’t buy it. ... show more
