I have one with a red nozzle and have no problems!

 

I have the 18v. It's a nice sprayer - especially if you already have the tools/batteries. Keep an eye on the hose where it attaches to the sprayer (through the plastic housing) it gets worn and will eventually break. Mine did but I had been keeping an eye on it so I was prepared. The housing has to be disassembled to access the hose connection. I found a you tube video showing how and what tools were needed.

Not sure if the insides are the same on the 40 but my pump can be a little temperamental. Sometimes it seems like it's fully primed then it kicks in for real and I realize it wasn't spraying quite at full force.

I got sick of carrying the weight and I have a lot of square feet to spray so I have a cart sprayer now with a 125' hose.

Someday I plan to swap out the pump in the Ryobi... (I already "upgraded" the hose when it finally gave out)

If I were to buy another backpack sprayer I'd probably follow the advice I've seen here and get one of the FlowZone ones...

I have tons of batteries for both the 18v for power tools and and the 40 volt for yard stuff. There is a 2 gallon 18v and then the 4 gallon 18v or 40v. Will probably go with the 40v to keep all the yard stuff in one place.

 

Was talking to my exterminator earlier today and asked him about his backpack, appears to be a FlowZone and he has one of these.

Typhoon 2.5 5-Position Battery Powered Sprayer (4-Gallon) | FlowZone®

A favorite of the pros, the TYPHOON 4-gallon sprayer has been updated with a 5-POSITION VARIABLE PRESSURE DIAL (up to 115 psi). Spray for 3+ hours on one charge and over 30-feet! The TYPHOON 2.5 provides all-day comfort and can withstand demanding projects.

Uses same tips and wand as my pressure washer but 2x the Ryobi.

Now I am wondering if I should just go with the manual Harbor Freight one for $25 to see if I actually will use it.

 

The FlowZone might be worth it from everything I see around here. You could always do what I did and use the Ryobi for a couple of years then upgrade if you find the need...

I don't think I would even consider a manual one unless you are only planning to do some random spot spraying. The battery ones are just so nice. Even for spraying bug spray around the perimeter of the house it's so nice to just pull the trigger and it goes.

Yeah, I would be spraying around the perimeter of the house 2x per year to keep bugs out of the mulch and the edges of driveway and sidewalk for chinch bugs and Bifen is way cheaper than buying the premixed stuff from Home Depot.

I guess I could repurpose the Ryobi in the future as a final rinse with distilled/filtered water when washing my car so that it is not a race to dry it before the liquid chalk they call water around here leaves water spots.
