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 snuggly across the torso and curve to the contour of the user's body. 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. Review: Great sprayer! - I had Dewalt 20v batteries from having Dewalt tools. So I thought I'd give this 4 gallon sprayer a try. Love it! No more pumping the sprayer. I can spray my entire property within 10 minutes easily with a heavy spray. It is very well made too. Battery life was still on full when I finished. So the unit is very efficient. ## Features - Heavy-duty nylon-reinforced hose effectively avoids kinking - Variflo technology efficiently adjusts the flow of operator - Triple-filtration system helps minimize clogging ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BNP9RDZQ | | Best Sellers Rank | #6,020 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #37 in Lawn & Garden Sprayers | | Brand | DEWALT | | Brand Name | DEWALT | | Color | Yellow | | Customer Reviews | 4.7 out of 5 stars 298 Reviews | | Hose Length | 50 Inches | | Included Components | Tool Only | | Item Dimensions W x H | 10"W x 22.5"H | | Item Type Name | DEWALT 20V* Lithium-ion Battery Powered Backpack (Tool Only), 4 Gallons | | Item Weight | 16.27 Pounds | | Manufacturer | The Fountainhead Group Inc. | | Manufacturer Part Number | 190742 | | Manufacturer Warranty Description | 3 year limited warranty | | Material | Polypropylene (PP) | | Material Type | Polypropylene (PP) | | Maximum Pressure | 3000 Pound per Square Inch | | Model Name | DEWALT 20V* Lithium-ion Battery Powered Backpack (Tool Only), 4 Gallons | | Model Number | DXSP190681B | | Power Source | Battery Powered | | Product Dimensions | 10"W x 22.5"H | | Style Name | Adjustable,Curve,Deluxe | | Tank Volume | 4 Gallons | | UPC | 841688007079 | ## Product Details - **Brand:** DEWALT - **Color:** Yellow - **Item Weight:** 16.27 Pounds - **Material:** Polypropylene (PP) - **Tank Volume:** 4 Gallons ## Images ![DEWALT 20V* Lithium-ion Battery Powered Backpack (Tool Only), 4 Gallons - Image 1](https://m.media-amazon.com/images/I/51p5ALVbpDL.jpg) ![DEWALT 20V* Lithium-ion Battery Powered Backpack (Tool Only), 4 Gallons - Image 2](https://m.media-amazon.com/images/I/51w1cRcfpGL.jpg) ![DEWALT 20V* Lithium-ion Battery Powered Backpack (Tool Only), 4 Gallons - Image 3](https://m.media-amazon.com/images/I/619yn0lQMkL.jpg) ![DEWALT 20V* Lithium-ion Battery Powered Backpack (Tool Only), 4 Gallons - Image 4](https://m.media-amazon.com/images/I/71UmzoHQ8lL.jpg) ![DEWALT 20V* Lithium-ion Battery Powered Backpack (Tool Only), 4 Gallons - Image 5](https://m.media-amazon.com/images/I/615Dw77f3kL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Dewalt Sprayer - Excellent! *by B***Y on February 26, 2026* 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.
