The Simpson Cleaning surface cleaner emphasizes its capability to provide 10X more coverage than standard nozzles, thanks to its two high-pressure rotating jets. This feature is particularly advantageous for larger jobs, allowing users to clean vast areas quickly. Conversely, the Westinghouse attachment highlights its ability to achieve professional-level cleaning results, which may appeal to users seeking a more heavy-duty option. With a pressure rating of up to 4400 PSI, it could be more effective on tougher grime and dirt, making it a strong contender for challenging cleaning tasks.
Design and Durability
Both the Simpson and Westinghouse surface cleaners are designed with durability in mind. The Simpson model features a stainless steel shroud and nozzles, providing protection against corrosion and enhancing its lifespan. This construction not only ensures durability but also minimizes overspray, keeping users and surrounding areas drier during operation. Meanwhile, the Westinghouse attachment also utilizes durable stainless steel, which is both light and easy to store. Its design is user-friendly, catering to both professionals and homeowners, ensuring that anyone can handle it effectively.
Compatibility and Versatility
Compatibility is a crucial factor when choosing a pressure washer attachment. The Simpson Cleaning model is designed to work with gas-powered pressure washers that have ratings between 2000 PSI and 4000 PSI, while the Westinghouse attachment is compatible with most gas and electric pressure washers featuring a 1/4-inch quick-connect fitting. This universal compatibility makes the Westinghouse model more versatile for users who own different types of pressure washers. However, both products are aimed at providing excellent performance, and their 16.5-inch cleaning diameter ensures they can handle a variety of cleaning tasks.
Price Comparison
At a price of $99.00, the Simpson Cleaning Universal 16.5" Pressure Washer Surface Cleaner is priced higher than the Westinghouse model, which retails for $89.99. This $9.01 difference equates to about 10% more for the Simpson cleaner. While both products offer similar features and capabilities, the price difference may influence potential buyers, especially those looking to save on their purchase. However, price should be weighed alongside performance and features to determine the best value for individual needs.
Customer Reception

This suggests that the Westinghouse model is more popular among consumers, possibly due to its price point and performance capabilities. Customer reviews often highlight ease of use and effectiveness, emphasizing that both products appeal to a wide audience. However, the higher sales rank for the Westinghouse model may indicate a stronger preference among buyers in the market for pressure washer attachments.
Which should you buy?
Choosing between the Simpson Cleaning Universal 16.5" Pressure Washer Surface Cleaner and the Westinghouse Universal 16.5” Pressure Washer Surface Cleaner Attachment ultimately depends on your specific needs and budget. If you are looking for a more powerful option with a higher pressure rating, the Westinghouse model may be the better choice, especially considering its lower price of $89.99. However, if you prefer a product backed by a well-established brand with a focus on corrosion-resistant materials, the Simpson model at $99.00 could be worth the extra investment. Both attachments are effective for cleaning large surfaces, so your decision should align with your cleaning frequency and the types of surfaces you intend to tackle.
