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 designed to enhance your pressure washing experience, especially for tasks like washing cars, motorcycles, and cleaning various surfaces such as roofs and driveways. One of its notable strengths is the adjustable foam thickness, which allows users to customize the foam mixture for different cleaning needs. With a 1-liter capacity, this cannon is compact yet sufficient for most home usage, making it easy to manage without frequent refills. The adjustable nozzle and five different pressure washer nozzle tips (ranging from 0 to 65 degrees) offer versatility, enabling you to switch between different spray patterns based on your cleaning tasks.

In terms of build quality, the combination of brass and stainless steel materials suggests durability and resistance to wear over time. The 1/4-inch quick connector makes installation straightforward, and the cannon is compatible with various pressure washers operating between 1000 PSI to 3000 PSI, which covers a broad range of common residential units.

It does have a few drawbacks. Some users might find the 1-liter capacity a bit limiting for larger jobs, requiring more frequent refills. Additionally, while the adjustable features are a plus, they might take a bit of practice to get right, especially for those unfamiliar with foam cannons. Lastly, the foam performance can vary depending on the type of soap used and the pressure of the washer.

With a maximum pressure rating of 3600 PSI, it ensures powerful performance, making it suitable for a variety of cleaning tasks. The 3-liter capacity tank allows for ample soap storage, which can save you from frequent refills during larger cleaning projects.

The compatibility of this foam cannon is another strong point; it works with most pressure washers that have a 1/4” female quick-connect. This universal fit facilitates easy integration into your existing setup. Additionally, users appreciate the adjustable suds settings, allowing them to customize the foam concentration according to their specific cleaning needs.

There are some considerations to keep in mind. While the foam cannon is effective for creating thick foam, its performance may vary depending on the cleaning concentrate used. Lower-quality soaps can affect the thickness and effectiveness of the foam produced. While the build quality appears solid, it's essential to handle it with care to ensure longevity. The weight is manageable at 1.17 pounds, but some may find it a bit cumbersome during extended use. Still, for anyone looking to enhance their pressure washing capabilities, this foam cannon by Westinghouse offers a reliable and efficient option to achieve impressive cleaning results.
