    • No pressure; UPDATE 4/11/23
Style: Sprayer
UPDATE: Finally got a hold of customer service and the 2 guys in the technical department were very knowledgeable and very helpful-- they immediately sent me new part and it is fixed. SOLO has always been an icon in the backpack sprayer arena and their customer service shows this. Late review here... After only 3-4 uses (after 1-1/2 years), I have to continually pump to hold even moderate pressure. Not as good as the SOLO sprayers from years ago. I will be calling SOLO customer service next week. ... show more

    • Good sprayer, even for this gal !!
Style: Sprayer
It works well, and I left off the 5th star only because the straps don't have a chest-level cross-latch. Some might find this picky, but when you have 4 gallons of chemicals on your back, that weight tends to pull the backpack off your shoulders. As a 5'3" tall woman with good upper body strength, it adds stress to my back. My solution was to hand-fashion a cross latch with Velcro and nylon strap. Problem solved Otherwise, It works like a charm. + I like the fact that the gallon measurements are in raised in the plastic itself. It won't wear off! + The pump is easy to work, and I find that as I walk & spray, its easy to keep the pressure for continuous spraying. + It has a nice screen / filter at the opening. Just unscrew the top, fill with chemical(s), replace the screen/ filter, fill it with water from the hose, and you're good-to-go. Sometimes there's debris in water lines, and the screen/filter is the same heavy duty material found in the backpack itself to prevent those particles entering your water reservoir and, subsequently, clog the tube system . + I really like the base, designed to keep it upright, even on uneven surfaces. Since I'm short, I can set it on a trash can, add chemicals and water, and just step into the straps and hoist it onto my shoulders, without stressing my back (by lifting it from the ground up to my shoulders). ... .The base keeps it steady, even when I'm not graceful in hoisting it onto my back! I've been using it for about 3 months now, and it's so easy, and I don't get tired (as I did with the smaller, hand held type sprayers), so I find I use it much more often, and the weeds don't get ahead of me. I would buy it again, for sure. Hope this helps --- Leslie in East Tennessee ... show more

    • Not a bad sprayer, although it needs a much better spray wand
Style: Sprayer
I like this backpack sprayer because it's just easier to make up a 3 or 4 gallon load of spray and move around our hilly property with it on my back. It's much less work than carrying a 1 or 2 gallon sprayer in one hand or on one shoulder. Having the ability to fill this with 4 gallons at a time makes the job take a little less time and that's helpful too. I didn't pay attention when I ordered and I bought this piston style this time, whereas in the past we've always bought the diaphragm style. I am not sure that I perceive a real difference in use, although they look different and there are separate instructions for each in the Solo manual. This piston backpack worked fine. I am 5'8" tall and almost 70 years old and the weight and distribution were acceptable. The rod or bar that is used to pressurize the spray is at a convenient location at the side and was easy enough to pump. The spray handle itself gave me some trouble and soon became stuck in the constant-spray position because the plastic was soft and got wedged into the little groove. That isn't good, so I knocked off a star. The spray pattern is OK. I usually use fairly large drops because it seems we always have at least a little wind and I don't want the overspray going everywhere. Not a bad sprayer, although it needs a much better spray wand. ... show more

    • I wanted a sprayer similar to what the pest control companies use and this sprayer meets my criteria
Style: Sprayer
I wanted a sprayer similar to what the pest control companies use, and this meets the criteria. It was easy to unpack and get started with. The pump arm works great. It is so nice to be able to pump a sprayer without having to put it on flat ground. And I do not have to pump it as much as one of those cheap sprayers that you carry and have to place on the ground to pump. I can keep my spray pattern consistent by quickly and easily doing one more pump using the arm, which really speeds up my work. Only time will tell how well it holds up, but so far I love it. Well worth the money. ... show more

    • strong and steady stream, but seems to be fragile
Style: Sprayer
I gave this three stars because it sprayed me in the face and drenched my shirt and nearly came apart after the third use. I'm not sure if that's the Roundup I was using or if I put too much pressure in it. I will try again, but I have my hesitations. would it does work it's very strong in the pressure is very high and it's very easy to control. ... show more

    • performs as expected
Style: Sprayer
Purchased this over a year ago when I was removing popcorn ceilings, I've used it many times since, No issues. The quality of build and functionality is better than I expected. This is a tool not an accessory so Don't expect it to feel like you're wearing a regular backpack. The hard plastic tank is curved to make it more comfortable and the padded straps adequately distribute the weight of 4 gallons of liquid that you'll be walking around with. I've had several tank sprayers and this one is far more convenient. I can spray the perimeter of my house with one tank in half the time. The top cap where you fill the tank started leaking on mine, I think there was an O-ring or a Gasket that fell out. Easy fix, replaced the gasket and good as new. I've left this outside in the sun for weeks and dropped it/ stepped on nozzle tip over the year that that I've had it. Durable, Quality Tool. If it leaks or has issues building pressure, get an O-ring for the top cap ... show more
