I'm looking fit a good sprayer to apply bleach to roofs affected by algae and moss would this be a good sprayer to use? If not could you recommend one? Thanks
It would not be recommended to use bleach in the Solo 425 4-Gallon Professional Piston Backpack Sprayer. Instead you could use the Chapin Euro Bleach Backpack Sprayer 4 Gal. (61575) or Chapin Industrial Poly Bleach Sprayer 1 Gal. (20075) designed to hold up against this harsh chemical.

No, the Solo 425 4 Gallon Professional Backpack Sprayer is a pump sprayer. If you are looking for a battery-powered sprayer, you may want to consider the Solo 416 Battery Backpack Sprayer.
