WORX Cordless Yard Sprayer 20V 2-Gallon WG829 — Battery Kit with Automatic Air Pump & Wand Storage

The WORX 20V Cordless Yard Sprayer WG829 is a battery-powered, automatic 2-gallon sprayer that delivers continuous spray without hand-pumping for fertilizers, herbicides and insect solutions.

Designed as part of the WORX PowerShare platform, this cordless sprayer replaces manual pump bottles with an air-driven automatic pump that never touches the tank contents, reducing contamination risk. It ships with a 2.0Ah PowerShare battery and a 4-amp charger, but you can also buy the bare unit if you already own WORX PowerShare batteries. Lightweight and portable with built-in wand storage and a shoulder strap, the WG829 is built for repeat yard applications where comfort and consistent coverage matter.

How does the automatic pump improve spray consistency?

The WG829 uses an air-compressor style pump that pressurizes the tank automatically, so you get a steady flow instead of variable bursts from manual pumping. Because the pump creates pressure without contacting the liquid, there's no cross-contamination when switching tanks. That consistent pressure helps produce even coverage for lawn treatments and pest control.

• Automatic air-driven pump for continuous spray
• Pump does not contact tank liquids — safer switching between solutions
• Threaded pump fits many common manual-pump tanks
• Variable nozzle for fine mist to targeted stream

What are the battery and compatibility options?

As a PowerShare product, the WG829 works with WORX 20V, 40V and 80V batteries via the shared platform, so you can use batteries you already own. The model is available as a kit with a 2.0Ah battery and charger or as a battery-free unit for users who want to save by using existing PowerShare cells. Batteries are intelligent for optimized run time and performance across WORX tools.

• Includes 2.0Ah PowerShare battery and 4-amp charger (kit version)
• Bare unit option available for existing PowerShare users
• Cross-compatible with WORX 20V/40V/80V platform
• Efficient motorized pump for longer continuous use

How easy is it to refill, store and maintain?

Refilling and cleanup are simplified with a pressure release valve that vents the tank quickly and a built-in wand holder for tidy storage. The pump’s thread matches common yard sprayer tanks, and because the pump mechanism doesn’t touch liquids, you can swap tanks without needing extensive rinsing of the pump. The lightweight shoulder strap and compact wand storage make transport and stowing hassle-free.

• Pressure release valve for fast, safe refills
• Built-in wand storage keeps nozzle protected and compact
• Shoulder strap reduces fatigue during extended use
• Pump thread compatible with many third-party manual tanks

What can I spray with the WORX WG829 safely?

The WG829 is suitable for a wide range of common landscape liquids such as fertilizers, herbicides, insecticides and plant treatments designed for handheld sprayers. Because the pump does not contact the liquid, it minimizes contamination risk when using different solutions. Always follow product labels and safety guidance for each treatment you apply.

• Fertilizers and foliar feeds formulated for handheld sprayers
• Herbicides and weed control solutions for yard use
• Insecticidal solutions labeled for sprayer application
• Gardening and lawn-care liquids compatible with plastic tanks

Who is this for: The WORX 20V Cordless Yard Sprayer WG829 suits homeowners, small-scale landscapers and garden enthusiasts who want a cordless, low-effort alternative to hand-pump sprayers. It’s ideal for users who need consistent coverage across lawns, beds and around structures, and for anyone already invested in the WORX PowerShare battery ecosystem seeking to avoid extra battery purchases.
