## Description

The DEWALT 4 Gal. Lithium-ion Powered Backpack Sprayer has been built to outperform, outlast and finish the job in less time - with no more pumping. The lithium-ion powered backpack sprayer has Variflo technology which allows the operator to adjust the flow for multiple applications using specific nozzles for consistent spraying. This sprayer has a deluxe harness with wide, padded shoulder straps that fit snug across the torso and curve to the contour of the user's body. 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. It includes a 50 in. heavy-duty nylon-reinforced hose and strain relief system preventing the hose from kinking at the chemical exit point. This sprayer unit is also equipped with chemically resistant Viton seals throughout to withstand the effects of harsh chemicals. Whether it's for weeding and feeding, disinfecting, finishing concrete, eliminating mold or controlling pests - users are equipped for the Job. It's GUARANTEED TOUGH .

Review: Powerful, reliable, and easy to use - I’ve been very impressed with this DEWALT backpack sprayer. The battery-powered design makes spraying much easier than a manual pump, especially for larger jobs. It provides consistent pressure, which helps give an even spray without constantly stopping to pump. The backpack is comfortable to wear, the tank is easy to fill and clean, and the battery lasts long enough to complete most tasks on a single charge. The build quality feels solid, just like you’d expect from DEWALT. Overall, this is a great investment if you already use DEWALT 20V tools or need a dependable sprayer for lawn care, weeds, or other outdoor projects. I’d definitely recommend it.
Review: Dewalt Sprayer - Excellent! - I was initially skeptical about the price of this sprayer, but since I already owned a DeWalt drill battery, I decided to give it a try. Having used both 2-gallon and 4-gallon manual pump backpack sprayers in the past, I can say there is simply no comparison; this electric sprayer is a game changer. What normally takes me 45 minutes to complete was finished in about 15 minutes. The efficiency is incredible, as I no longer have to stop and pump every few minutes. While it has the weight you would expect from a 4-gallon backpack, it is manageable, and I found that filling it with 2 gallons was plenty for my needs. For those who prefer not to carry it, some companies make wheeled trolleys to pull the unit behind you. The unit is very quiet, features 10 spray settings, and produces an excellent spray pattern that can reach long distances. The build quality is sturdy, and the shoulder harness is extremely comfortable. I used a small 1.5 Ah battery to spray around my house, pool, deck, and pavilion, and it still showed a full charge when I was finished. I am so impressed that I am getting rid of my manual sprayers. If you are looking to upgrade your equipment (Man Card), I HIGHLY recommend this DeWalt sprayer. 10 stars.
