This is the same as the bleach sprayer. One is about 15 and the other is 20. Couldn’t see what the difference was so I called chapin. They said they are the same, one is available online in their store and the other isn’t. Both are listed on the zon, so I don’t know why they would do that. Anyway, it isn’t the greatest but it works and when it dies it is cheap to replace. I use it for spot treating things like a little lichen on the edge of a sidewalk that didn’t come out while running the SC or rinsing. You’ve been there, do a black piece of concrete and after a pass you see the junk that wasn’t visible and didn’t come up with the HW mix pre wet.
I break one every couple of months and I’m just a part timer.
