I would not purchase again to many issues.
lets just stick with the problems cause bottom line for the amount of money should not be having these issues: when the tank has about 1/2 gallon of product will not empty leaving product that can not be used, + the pressure is not consistent , ive used plenty other sprayers 1/3 of the price of this 1 and worked better

Good sprayer for homeowner but not a professional
I use a backpack sprayer every day on the job. I gave up my manual pump sprayers this year for this battery powered sprayer for the convenience. I chose Milwaukee because I had never been disappointed by their tools and they have stood up to a lot of abuse. The first couple of months I liked it but now that I have reached the end of my spray season i’m going to junk it and go back to birchmeier. What I liked - not manually pumping the sprayer. My issues - hand fatigue- I wear a large size glove so my hands aren’t small- the handle is larger than my other sprayers and after about 2 tanks my hands hurt. The tank lost pressure when 1) it wasn’t perfectly vertical. If you made a slight bend at the waist to adjust your spray position you lose pressure and have to wait for it to come back. 2) if there is 1 gallon or less you lose pressure. If you put 3 gallons in the tank, it was good for the first 2. It took forever to spray that last gallon out, I eventually gave up and left 1 gallon in the tank at all times. That’s extra weight and less production for the volume in the tank, which is not good when you have a long distance between where you fill up and the spray area. If you want a dry tank at the end of the day, easier to dump it out than wait for it to spray out. The seal in one lid broke so now that tank leaks if it is not vertical. The tank that got the most use this summer needs a new spray nozzle or seal replacement as it developed a bad drip. After several months of use I can barely spray a distance of 4’. It’s not tank related as all of my tanks do this when I switch them out. I haven’t tried to resolve this issue because i’m done with them. My other tanks could go at least 5 years under the same conditions before having these problems, if at all. For a homeowner that wants to spray something around the property once a month it would work fine.

I would buy again if they made it better
I have had mine for 2 weeks...found out the lid don't seal and ran a load of chemical down my back. The screen is inaccessible if there is any chemical in the tank..And the screen is TINY.... after the first week I had to hit the handle to make it pump...they need to talk with people who use it more than once a day....

Great piece of equipment
This thing is fantastic. Live the adjustments on it and the amount this thing will spray is crazy. Very comfortable straps. Would recommend this to anyone.

Good quality sprayer
It's pretty good I haven't had any problem with it. Its built solid. The only thing I noticed is I go through the chemical way faster because I am not constantly pumping all the time.

Great product for the HVAC Technician
We sell and use this product for coil cleaning and rinsing. It's great for carrying multiple cleaners without having to dump and rinse tanks. Great for commercial rooftops & VRF as well as residential heat pumps and a/c condensers.

What is the weigh of the sprayer when it is empty?
Richard S on Jul 4, 2019
BEST ANSWER: The sprayer weighs 17.5 pounds. The quality of this sprayer is excellent. The only thing I have any complaint about is the weight, with a few gallons of water it can be a challenge for your feet, ankles,knees,and joints. At least your hands and arms are carrying same as nothing. Hope this helps.
What makes the sprayer surge and also it keeps dribbling after I let go of the trigger?
A shopper on Aug 10, 2019
BEST ANSWER: Your question will be best answered by the manufacturer, who can provide you with the accurate information. The number to reach the technician is 1-800-729-3878.
