Rainmaker 5 Gallon Battery Powered Sprayer

No-Pump Battery Spraying for Large-Area Jobs, 5 Gallon

Manual pump sprayers work fine for a few minutes of spraying, but constant pumping becomes a real fatigue factor once a job stretches across a larger area. The Rainmaker 5 Gallon Battery Powered Sprayer removes the pumping step entirely, using a rechargeable battery to maintain spray pressure so the operator can focus on coverage instead of arm strength.

At 5 gallons, this unit is sized for larger jobs than a hand-carried pump sprayer, and its pull cart and padded backpack straps let it be moved across a site by either method depending on the terrain.

Key Features & Benefits

• Rechargeable battery power — eliminates manual pumping for extended, consistent spraying.
• Lock-on trigger — enables continuous spraying without holding the trigger the whole time.
• Attached pull cart and backpack straps — move the sprayer by cart on flat ground or wear it as a backpack elsewhere.
• Integrated filter and 4 ft hose — supports cleaner spraying and easier reach across a work area.
• Broad application range — suited to herbicides, pesticides, liquid fertilizers, and other home and commercial spray applications.

Who Should Use This Sprayer

This sprayer fits growers and property managers covering large areas who want to avoid the fatigue of manual pumping, and who can use either the pull cart or backpack straps depending on the site. Smaller jobs or tight indoor spaces may be better suited to a compact 2 gallon pump sprayer instead.
