The RIDGE WASHER cleaner is priced at $35.99, while the Westinghouse foam cannon is about 50% cheaper at $17.99. Both products serve distinct purposes in the realm of pressure washing, making them suitable for different cleaning tasks.
Purpose and Functionality
The RIDGE WASHER Pressure Washer Undercarriage Cleaner is designed specifically to clean undercarriages of vehicles, including cars, trucks, and SUVs. It boasts a pressure range of 1500 PSI to 4000 PSI, making it effective for heavy-duty cleaning tasks. In contrast, the Westinghouse Foam Cannon is aimed at delivering a thick, even layer of foam for general cleaning applications, rated up to 3600 PSI. While both accessories enhance the cleaning power of pressure washers, they cater to different cleaning needs—one specializes in undercarriage cleaning, while the other excels in foaming surfaces for washing.
Design and Usability
The RIDGE WASHER cleaner features a user-friendly design with a 16.1-inch cleaning area, complemented by a straight extension wand and a curved wand for versatility. This design allows users to easily maneuver under vehicles without the need to crawl underneath. The Westinghouse Foam Cannon, on the other hand, is also designed for ease of use, featuring a simple soap tank reservoir that transforms cleaning concentrate into foam. With a universal 1/4” quick connect, it can be effortlessly attached to most pressure washers, making it accessible for both novices and professionals alike.
Cleaning Performance
When it comes to cleaning performance, the RIDGE WASHER shines with its capability to tackle road grime, oil, and dirt from vehicle undercarriages. It performs best with a pressure of 2500 PSI or higher, ensuring thorough cleaning. The Westinghouse Foam Cannon, while more affordable, is renowned for its ability to create thick snow foam, providing comprehensive coverage for surfaces like cars and outdoor areas. Each product excels in its domain; the undercarriage cleaner is ideal for specific vehicle maintenance, while the foam cannon is perfect for general washing tasks.

The RIDGE WASHER is currently priced at $35.99, while the Westinghouse Foam Cannon costs $17.99, making it about 50% cheaper. This significant price difference may influence your purchasing decision, especially if you are looking for a budget-friendly option. However, the price of the RIDGE WASHER reflects its specialized design and functionality for undercarriage cleaning, which may justify the higher cost for those who require such a tool.
Sales and Popularity
