Greenworks High-Pressure Soap Applicator — Universal 3100 PSI, 1/4-inch Quick Connect Foam Cannon

The Greenworks High Pressure Soap Applicator is a universal pressure washer attachment that delivers concentrated detergent application at pressures up to 3100 PSI for faster, more even cleaning.

This compact foam cannon-style applicator snaps onto most pressure washers and makes soaping surfaces quicker and more efficient. Designed by Greenworks to work with its own pressure washers and many other brands, the nozzle blends detergent with high-pressure water flow so you coat cars, siding, decks, patios and outdoor furniture with minimal waste. It accepts cleaners safely up to a maximum water temperature of 40°C and offers a 1/4-inch quick connection for fast setup.

How does the soap applicator improve cleaning results?

The applicator atomizes detergent into a thick foam that clings to vertical and horizontal surfaces, giving cleaning agents more time to loosen dirt and grime before rinsing. This helps you reduce scrubbing while covering a wider area per pass.

• Delivers up to 1.4 GPM for steady detergent flow.
• Creates dense foam for better cling on vertical surfaces like siding and vehicles.
• Works with common pressure washers to speed up prep and cleaning tasks.

What pressure and temperature limits should I observe?

Use the soap applicator with pressure washers rated up to 3100 PSI to remain within safe operating limits. The unit is designed for cold-to-lukewarm water only; the maximum water temperature is 40°C (104°F), so avoid hot water systems.

• Compatible with pressure washers up to 3100 PSI maximum.
• Maximum water temperature: 40°C (104°F).
• 1/4-inch quick connection for a secure, tool-free hookup.

Is it easy to attach, adjust and clean?

The applicator uses a 1/4-inch quick connect so you can attach or remove it in seconds without tools. An easy on/off dial lets you control detergent flow quickly, and disassembly is straightforward for rinsing or winter storage.

• 1/4 in. quick connection for rapid attachment and removal.
• Easy on/off dial to adjust detergent delivery on the fly.
• Simple interior access for rinsing residue after use.

Which pressure washers and cleaners are compatible?

The Greenworks applicator is built to work directly with Greenworks pressure washers and is also compatible with many other brands that accept 1/4-inch quick-connect accessories. Standard detergents designed for pressure washer use are recommended to preserve nozzle performance.

• Compatible with all Greenworks pressure washers and many other units with the same connection type.
• Works with typical pressure-washer detergents (observe manufacturer recommendations).
• Note: Item may show residual water from factory quality testing; this does not affect performance.

Who is this for? Homeowners, DIYers and light commercial users who want quicker, more uniform detergent application will benefit from the Greenworks High Pressure Soap Applicator. It’s a good match if you already own a compatible pressure washer or plan to use a unit rated up to 3100 PSI and you need an easy-to-use accessory that saves time on car washes, decks, patios, and exterior siding. If you require high-temperature detergent systems or heavy industrial cleaning above 3100 PSI, choose a product rated for those conditions instead.
