The Clorox® Total 360® electrostatic sprayer imparts an electrical charge to the liquid droplets whereas a trigger sprayer does not. The charged droplets are actively attracted to surfaces providing uniform coverage, whereas non-charged droplets from a trigger sprayer passively fall on surfaces based on the direction of spray and gravity and may result in uneven coverage.
Electrostatic spraying is the process of applying a charged liquid to a surface. In the process, liquids are atomized into droplets which are the charged by the application of an electrical current as they exit the sprayer. When the charged droplets approach a surface they induce an opposite charge on the surface which then attracts the charged droplet to the surface. The charged droplets also repel each other, preventing them from coalescing into larger droplets. The repulsion also allows the droplet to uniformly cover surfaces. Droplets can even be attracted to the backs of surfaces regardless of the direction of spray, enabling them to “wrap” around a range of surface types including curved surfaces. In this respect, electrostatic spraying can be considered an “active” application technology in that liquid droplets are attracted to surfaces. With normal or non-charged “passive” spraying, the coverage of surfaces is determined by the direction of spray and where the droplets fall based on the effect of gravity, and may result in uneven surface coverage
