Westinghouse Foam Cannon for Pressure Washers — 3600 PSI, 1/4” Quick-Connect, Adjustable Foam Control

The Westinghouse Foam Cannon is a heavy-duty pressure washer attachment that converts cleaning solution into thick, clinging foam for faster, safer surface cleaning up to 3600 PSI.

This foam lance is built for both homeowners and professionals who need an efficient, repeatable way to pre-soak vehicles, siding, patio furniture and other outdoor surfaces. With a universal 1/4” quick-connect, adjustable foam control, and a durable construction designed to stand up to daily use, it streamlines rinsing and reduces scrubbing time when paired with your preferred detergent. Westinghouse backs the product with a 180-day warranty, reflecting a century-plus reputation for reliable tools.

How does the foam cannon improve cleaning speed and coverage?

By turning diluted soap into a dense snow-like foam, the lance clings to vertical and horizontal surfaces so cleaning agents work longer on grime and road film. That longer dwell time loosens contaminants and lets you rinse them away with less elbow grease.

• Generates thick foam that sticks to paint, glass, wood and fabric
• Even coverage reduces missed spots and repeat passes
• Adjustable nozzle and soap mixture for light or heavy sudsing

Which pressure washers and nozzles is this compatible with?

The unit includes a 1/4” female quick-connect designed to fit most consumer and commercial pressure washers, both gas and electric. It’s rated to operate safely up to 3600 PSI, so it pairs well with a wide range of machines used for vehicle detailing and property maintenance.

• 1/4” universal quick-connect fitting for fast attachment swaps
• Works with standard tip nozzles used on many washers
• Suitable for most gas and electric models within PSI rating

How do I adjust foam density and use cleaning solutions correctly?

Control foam thickness by changing the soap reservoir dilution and the cannon’s adjustable nozzle. Start with manufacturer-recommended detergent dilution and fine-tune spray flow until you achieve the desired suds and cling for the surface and soil level.

• Fill tank with preferred soap, dilute according to directions
• Turn adjustment knob to increase or decrease foam output
• Rinse thoroughly after dwell time to remove loosened grime

Is the foam cannon durable enough for regular use?

The Westinghouse foam lance is constructed to resist cracking and handle daily high-pressure exposure when used within the specified PSI limits. Its materials and connections are chosen for repeated attachment and removal, making it a dependable component of a professional detailer’s or homeowner’s toolkit.

• Heavy-duty construction resists wear from frequent use
• Sturdy quick-connect prevents leaks and loosening during operation
• Backed by a 180-day customer warranty for added assurance

Who is this for: The Westinghouse Foam Cannon is ideal for car enthusiasts, detailing shops, landscapers, property managers and homeowners who want faster, more effective washing of vehicles, windows, fences, awnings and outdoor furniture. If you already own a compatible pressure washer and want to reduce scrubbing time while improving cleaning uniformity, this foam lance is a practical, easy-to-use upgrade.
