Greenworks 80V Cordless 4-Gallon Backpack Sprayer — 70 PSI High-Pressure, 5 Nozzles

The Greenworks 80V backpack sprayer is a cordless, high-pressure 4-gallon sprayer delivering up to 70 PSI and multiple nozzle options for weed control, pest treatment, sanitizing, and general garden spraying.

This battery-powered backpack sprayer combines a roomy 4-gallon tank with the efficiency of Greenworks 80V lithium-ion power (battery sold separately) to handle large jobs without the fumes or pull of gas models. Designed for longer runs and professional use, the unit sprays up to 25 feet and works with five interchangeable tips to match precise spot work or wide coverage. Comfort-focused straps and straightforward controls make it easier to move through yards, beds, and commercial properties while maintaining steady output.

How powerful and far can this sprayer reach?

The sprayer produces up to 70 PSI, which gives a steady, forceful stream suitable for penetrating foliage, reaching tall weeds, and covering hard-to-reach areas up to about 25 feet. Consistent pressure helps maintain uniform application without frequent pump cycling.

• Maximum pressure: 70 PSI for strong spray force.
• Spray distance: effective reach approximately 25 feet.
• Consistent output for even coverage across broad areas.

How long will it run and how big is the tank?

Equipped with a 4-gallon reservoir, this backpack sprayer balances capacity and portability so you spend more time spraying and less time refilling. Paired with a Greenworks 2.0Ah 80V battery, users can spray up to an estimated 200 gallons per charge under normal conditions, providing all-day productivity on many jobs.

• Tank size: 4 gallons for extended work cycles.
• Estimated coverage per charge: up to 200 gallons with a 2.0Ah 80V battery.
• Tool-only purchase: battery and charger sold separately to match your existing Greenworks ecosystem.

What spray patterns and tasks can it handle?

Five included nozzle tips let you switch between concentrated bursts and wide fan patterns to fit the task—spot-treat weeds, apply pesticides, disinfect surfaces, or irrigate delicate plantings. The adjustable tip gives variable flow control, while the fan and multi-hole tips cover larger swaths quickly.

• Nozzles included: double head, single head, fan, 4-hole, and adjustable tip.
• Applications: weed control, pest treatment, sanitizing, foliar feeding, and general garden spraying.
• Adjustability: variable tip for flow control and interchangeable heads for pattern selection.

Is it comfortable and durable enough for commercial use?

This model is built with durability and operator comfort in mind—double-padded, adjustable shoulder straps reduce fatigue, and a balanced backpack layout helps distribute weight for long shifts. Greenworks backs the sprayer with a 4-year tool and battery warranty when used with compatible batteries, reflecting its design for frequent, heavy-duty use.

• Comfort: adjustable double-padded shoulder straps for reduced strain.
