Overview

The Greenworks model is priced at $499.99, while the Westinghouse is about 30% cheaper at $349.00. Both are designed to tackle tough cleaning jobs, but they differ significantly in their power delivery, functionality, and intended use.
Power and Performance
The Greenworks Pro Brushless 3000 PSI features a powerful 14 Amp TruBrushless motor that generates 3000 PSI at a flow rate of 2.0 GPM. This setup allows for effective cleaning of various surfaces, including decks, siding, and vehicles. In contrast, the Westinghouse WPX3400 boasts a higher maximum PSI of 3400 and a flow rate of 2.6 GPM, making it better suited for heavy-duty tasks. The additional power can handle tougher grime and larger areas more efficiently, highlighting a clear advantage for users with extensive cleaning needs.
Portability
Portability is a crucial factor for many buyers, and here the Greenworks pressure washer shines with its foldable handles and lightweight design. The rugged steel frame and multiple grab points make it easy to transport. Meanwhile, the Westinghouse WPX3400 is also designed for mobility with its 12-inch never-flat wheels and lightweight construction. However, its gas-powered engine may require more effort for setup compared to the electric model. Both models offer features that enhance transportability, but the Greenworks has the edge in convenience for quick jobs.
Accessories and Usability
The Greenworks Pro comes equipped with a range of accessories, including a turbo nozzle and three additional nozzles, allowing versatility for various cleaning tasks. It also includes a 25-foot kink-resistant hose for ease of use. The Westinghouse WPX3400 also provides a comprehensive accessory package, featuring five quick-connect nozzles and a built-in soap tank for convenience. While both models offer valuable attachments, the Greenworks provides a more extensive set of nozzles, making it slightly more versatile for different cleaning applications.
Cleaning Capability
In terms of cleaning capability, the Westinghouse WPX3400 takes the lead with its higher PSI and GPM ratings, allowing it to deliver powerful, deep-cleaning performance. This is particularly beneficial for more challenging surfaces like brick and stone. The Greenworks Pro, while effective for everyday tasks, may struggle with tougher cleaning jobs compared to the Westinghouse. Users focused on heavy-duty applications may appreciate the added cleaning power of the Westinghouse model.
Ease of Maintenance
When it comes to maintenance, the Greenworks Pro’s electric motor requires minimal upkeep compared to the gas-powered Westinghouse WPX3400, which has a 212cc engine that necessitates regular maintenance such as oil checks and potential fuel management. The Westinghouse model is designed for durability but may require more attention over time. Therefore, the Greenworks Pro may appeal to users looking for a hassle-free option with lower maintenance demands.
Price Comparison
The price difference between the two models is significant, with the Greenworks Pro priced at $499.99 and the Westinghouse WPX3400 at $349.00. This means the Greenworks is approximately 43% more expensive than its rival. Buyers must consider what features and capabilities they need for their cleaning tasks. If budget is a primary concern, the Westinghouse offers compelling performance at a more accessible price point, making it a strong contender.
Customer Reception
Customer reception is another important aspect to consider. The Greenworks Pro has a sales rank of 4888, indicating a steady level of interest, while the Westinghouse WPX3400 ranks significantly better at 695, suggesting it is a popular choice among consumers. This could be attributed to its balance of price and performance, making it a favorite for those seeking effective cleaning solutions without breaking the bank.
Which should you buy?
Ultimately, the choice between the Greenworks Pro Brushless 3000 PSI and the Westinghouse WPX3400 boils down to your specific needs and preferences. If you prioritize higher cleaning power and are tackling tougher jobs, the Westinghouse is the better option with its 3400 PSI and more budget-friendly price of $349.00. However, if you prefer an electric model with lower maintenance requirements and versatile attachments, the Greenworks Pro at $499.99 could be the right fit for your lighter cleaning tasks.
