## Description

desertcart.com : DEWALT 20V* Lithium-ion Battery Powered Backpack (Tool Only), 4 Gallons : Patio, Lawn & Garden

Review: Great Value - Excellent Performance - Great product. I have a lot of fence line to spray for weeds. This electric sprayer works very well. I found it to be well made and the back pack assembly distributed the weight (+/-45 pounds) comfortably. I used a 6 Amp battery and the pump performed flawlessly for three complete, 4 gallon each, cycles. No leaks and the hose and wand were perfectly placed for my use (right handed). I'm 5' 10" tall and weigh 250 - the straps adjusted for me easily. One suggestion - when the backpack is full, place on a table, straps out, and back into the harness, tightening as you go. Highly recommend.
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.

Love it. Works great. Battery life is awesome. Used it probably 15 times and haven’t charged once and has not clogged (although I flush with water every 2-3 uses)
