Campbell Hausfeld makes this cordless power mister/sprayer to deliver water-soluble chemicals while reducing hand and joint fatigue. Instead of squeezing the trigger every spray, you just pull and hold the “Soft Touch” trigger for a continuous spray.
Rechargeable NiCad batteries power the sprayer for up to eight hours of spray time and last about 300 charges. A one-turn canister holds the solution and when secured is leak and spill resistant. When you’re done or need to change solutions, simply run hot water through the sprayer until it runs clear.
If you’re suffering from arthritis, carpal tunnel, or another hand condition, or if you just use a spray bottle a lot on your job, this $25 power tool might treat you right.
