Overview
In the world of pressure washing, attachments can significantly enhance your cleaning experience. The Greenworks 12" Surface Cleaner Pressure Washer Attachment and the MJJC Foam Cannon S V3.0 are two distinct products aimed at improving efficiency and effectiveness. While the Greenworks attachment is priced at $26.99, the MJJC foam cannon is substantially higher at $86.99, making it about 222% more expensive. This article will delve into their features, usability, and overall value to help you decide which product suits your needs better.
Cleaning Efficiency
When it comes to cleaning efficiency, the Greenworks 12" surface cleaner offers a cleaning width of 12 inches, making it ideal for larger surfaces like driveways and patios. This wide cleaning path allows you to cover more area in less time, which is particularly useful for extensive cleaning tasks. On the other hand, the MJJC Foam Cannon S V3.0 utilizes Thicker Snow Foam Technology to produce a creamy foam that clings to surfaces, enhancing the effectiveness of the cleaning process. While the Greenworks attachment is designed for broad coverage, the MJJC foam cannon excels in delivering a thorough wash, especially when combined with the right car shampoo.
Compatibility
Compatibility is crucial when selecting pressure washer accessories. The Greenworks 12" surface cleaner features a 1/4-inch quick connect, making it versatile enough to work with most pressure washers. This adaptability ensures that users can easily integrate it into their existing cleaning setups. Conversely, the MJJC Foam Cannon S V3.0 also includes a 1/4-inch quick connector, allowing it to be attached to a variety of pressure washers with ease. Both products offer similar compatibility features, but the choice depends on whether you need a surface cleaner or a foam cannon for your specific washing tasks.
Usability
Usability is a defining factor for any cleaning tool. The Greenworks surface cleaner is straightforward to use; simply attach it to your pressure washer and start cleaning. Its design is user-friendly, catering to both novice and experienced users. Meanwhile, the MJJC Foam Cannon S V3.0 boasts several upgrades for enhanced performance, including easier 360-degree spray control and a new bottle design that minimizes the risk of tipping over. This makes the foam cannon not only effective but also convenient during use. Although both tools are easy to operate, the MJJC foam cannon offers advanced features that enhance user experience.
Price Comparison
Price is a significant consideration when making a purchase decision. The Greenworks 12" surface cleaner is priced at $26.99, making it an economical choice for those looking to enhance their pressure washing capabilities without breaking the bank. In contrast, the MJJC Foam Cannon S V3.0 is available for $86.99, which is about 222% higher than the Greenworks product. While the MJJC foam cannon offers advanced technology, the price difference may deter budget-conscious buyers. Evaluating your cleaning needs against your budget is essential in this comparison.
Versatility
In terms of versatility, the Greenworks surface cleaner is designed specifically for flat surfaces, making it perfect for patios, driveways, and sidewalks. Its 12” cleaning width enables efficient cleaning across these areas. On the other hand, the MJJC Foam Cannon S V3.0 is engineered for a different purpose: producing foam for a thorough wash. This makes it particularly useful for car washing and other detailed cleaning tasks. While both products have their unique strengths, the Greenworks attachment may be more versatile in terms of surface cleaning, whereas the MJJC foam cannon excels in producing thick foam for specialized applications.
Brand Reputation
Both Greenworks and MJJC have established reputations within the pressure washing market. Greenworks is known for its reliable and innovative lawn and garden tools, while MJJC has gained attention for its effective foam cannon technology. The Greenworks 12" surface cleaner currently holds a bestseller rank of 2366, indicating a solid market presence and consumer trust. In comparison, the MJJC foam cannon trails with a bestseller rank of 9898. This difference suggests that, while both brands are reputable, Greenworks may have a slight edge in terms of consumer preference and trust in pressure washing products.
User Reviews

If you're looking for an economical solution to efficiently clean large flat surfaces, the Greenworks attachment at $26.99 is a solid choice.
