Product Description

High-Efficiency 4.2 Gallon Backpack Sprayer for Household and Horticulture

Engineered for both professionals and DIY homeowners, this battery-powered backpack sprayer simplifies outdoor maintenance and sanitation tasks. Whether you are applying liquid fertilizer across a vast garden, feeding nutrients to greenhouse plants, cleaning outdoor surfaces, or disinfecting public areas, the consistent performance saves you time and energy.

One-Touch Automatic Mixing: No More Manual Shaking

A common frustration with standard sprayers is quickly losing the mixing ratio as liquids separate. Our battery-operated unit solves this with a fully integrated mixing system. By simply pressing the dedicated stirring button, the internal impeller activates instantly. This keeps water-soluble solutions perfectly homogenized, ensuring that your first spray is as potent as your last, providing unmatched uniformity for lawn nutrition and growth.

Advanced Power Compatibility & Monitoring

Say goodbye to dead batteries mid-job. This tool accepts the widely trusted 20V platform, compatible with a complete range of battery models including DCB203, DCB204, and DCB606 (batteries sold separately). The intelligent power management displays a live voltage readout on the base of the unit—the L and N indicators let you monitor power output and remaining battery health at a glance. Over-heat and low-voltage protection further extend the lifecycle of your hardware.

Tailored Pressure for Delicate Plants and Heavy-Duty Cleaning

Unlike single-speed sprayers, our adjustable pressure regulator dials from 0 PSI to a maximum of 90 PSI. Coupled with the 6 interchangeable nozzle tips, you have complete control over droplet size and range:

• Fan Tip: Perfect for broad-area lawn coverage.
• Brass & Adjustable Nozzles: Ideal for high-reach wetting and deep cleaning.
• Double-Head & Single-Head: Efficient for precise, localized application.
• Shower Head: Gentle enough for fragile petals and seedlings.

The telescopic fiberglass wand extends to 39 inches for hard-to-reach areas without requiring a ladder, greatly enhancing safety.

Designed for All-Day Comfort and Simple Maintenance

We prioritized your physical comfort during large-scale chores. The sprayer features extra-thick padded shoulder straps and a stabilizing lumbar board that distributes the 4.2-gallon weight evenly across your back. The lock-on trigger reduces finger cramping during continuous spraying. After use, cleanup is straightforward. The extra-wide 4.7-inch tank opening prevents spills during refills, and the integrated side drainage allows you to empty residual water quickly without heavy lifting. A reusable filter screen prevents debris blockage, ensuring the pump's operational reliability.
