10 Best Pressure Washer Foam Cannons 2026 in the United States

The McKillans Pressure Washer Gun with Foam Cannon is a solid choice if you want to add thick, adjustable foam to your car washing routine. It comes as a complete starter kit with a swivel gun, foam cannon, and adapter, making it easy to get started without extra parts. The swivel inlet is a nice touch, preventing hose tangles and making long cleaning sessions more comfortable.

The foam cannon has a stable wide mouth bottle that holds a good amount of soap and won’t tip over easily during use. One of its best features is the adjustable foam output, letting you control how thick and wide the foam spray is, which is handy for both quick spot cleaning and full car washes. The foam is dense enough to lift dirt effectively and helps protect your paint from swirl marks. Build quality feels lightweight but sturdy, with preinstalled fittings sealed to avoid leaks.

Compatibility-wise, it fits standard pressure washers, but remember you need a pressure washer to use it—it’s not a standalone device. The 2.6 gallons per minute flow rate is typical for home use. Backed by mostly positive customer reviews and a one-year warranty, this is a dependable and user-friendly option for anyone looking to improve their car cleaning with foam.

The Greenworks 2700 PSI Pressure Washer is tailored for homeowners looking to tackle tough cleaning jobs around the house, such as siding, driveways, and patios. With a robust maximum pressure of 2700 PSI and a flow rate of 2.3 GPM, it offers a reliable solution for various outdoor cleaning tasks. One of its standout features is the innovative TruBrushless Motor Technology, which adjusts power depending on the nozzle used, effectively enhancing cleaning efficiency compared to many competitors.

The foam cannon included with this pressure washer provides a satisfying foam thickness, making it easier to lift dirt and grime during cleaning. Users appreciate how easy it is to start with a simple push-button mechanism, which adds to its convenience. The JETTFLOW technology also boosts water flow by up to 50%, allowing for quicker rinsing and reaching higher areas, which can be particularly beneficial for two-story homes.

Despite its durable build, weighing nearly 47 pounds, some users may find it a bit cumbersome to move around. Additionally, its maximum flow rate is decent but may not match the performance of some higher-end gas-powered models, especially for more intensive jobs. Furthermore, while compatibility with different nozzle types is good, users looking for extensive customization might find the options somewhat limited.

The Tool Daily Foam Cannon is a solid choice if you want to add thick foam cleaning to your pressure washer setup. It has an adjustable nozzle that lets you control foam thickness and spray pattern, which helps tailor the foam to different cleaning tasks like washing cars, motorcycles, or driveways. With a 1-liter bottle capacity, it holds a decent amount of soap solution, reducing frequent refills during your job.

The build includes both plastic and stainless steel parts, offering reasonable durability for regular home use, though it’s not fully metal which might limit its lifespan under heavy professional use. One standout feature is the dual connector with a two-way valve, letting you switch easily between the foam cannon and standard pressure washer tips without taking anything apart—this adds convenience if you need to alternate between foam and direct sprays. The package also includes five nozzle tips with different spray angles, giving you flexibility for various surfaces and cleaning tasks.

This foam cannon only works when attached to a pressure washer—it won’t fit garden hoses or faucets directly, so it’s not suitable if you don’t already have a compatible pressure washer. The maximum pressure rating of 3000 PSI fits most home and light commercial machines. This foam cannon is well-suited for users who want efficient foam cleaning with good adjustability and ease of use, as long as they have the right pressure washer connection. Its build quality and capacity are adequate for typical consumer use but might not withstand very heavy-duty or frequent professional cleaning.
