The Westinghouse WPX4400 Gas Pressure Washer is a powerful machine with a PSI of 4400 and a maximum GPM of 4.2, making it highly effective for deep cleaning tasks on decks, sidewalks, cars, and more. Its robust 420cc 4-stroke engine and triplex brass head pump ensure reliable performance and longevity. The 50-foot abrasion-resistant hose is notably long, offering great reach and flexibility during operation.

Additionally, the five quick-connect nozzles provide versatility for different cleaning tasks, and the included detergent system enhances its cleaning power for tough stains. The large 1.7-gallon gas tank allows for extended use without frequent refueling, which is convenient for larger projects. The sturdy steel frame and 12-inch never-flat wheels make it relatively easy to transport, despite its hefty 142-pound weight.

This machine is built to last and comes with a 3-year limited warranty, adding to its value. However, due to its power and size, it may not be the quietest option on the market, which could be a concern if noise levels are a priority. Its heavy weight might also make it less portable for some users. Despite these drawbacks, it is an excellent choice for those needing a powerful and reliable pressure washer for demanding cleaning tasks.

The Westinghouse WPX3400 Gas Pressure Washer offers impressive power with 3400 PSI and 2.6 GPM, making it suitable for a wide range of tough cleaning tasks like decks, driveways, and patio furniture. It comes equipped with a 1-gallon gas tank and a 0.5-gallon onboard soap tank, ensuring you can work for extended periods without frequent refills. The spray gun and 25-foot abrasion-resistant hose provide good reach and flexibility, while the 5 quick-connect nozzle options allow for versatile cleaning applications, from precise to broader coverage and soap application.

The 212cc 4-stroke engine is powerful and the maintenance-free axial cam pump ensures reliable performance. However, it is gas-powered and may not be as quiet as electric models, which is a consideration if noise is a significant concern for you. Portability is a strong point thanks to its tough steel frame and 12-inch never-flat wheels, making it easy to maneuver. Weighing 63 pounds, it is relatively heavy but manageable due to the robust wheel design.

The included tools and quick start guide simplify initial setup. While the washer is functionally tested, it might contain residual oil or fuel, which is an aspect to be aware of. A 3-year limited warranty offers peace of mind regarding service and parts coverage. This product is ideal for users needing a powerful, versatile, and portable gas pressure washer but might not be the best choice if you prioritize minimal noise.

The Dewalt 61147S gas pressure washer offers solid cleaning power with 3300 PSI and 2.4 gallons per minute, which is great for tackling tough outdoor tasks like decks, patios, and siding. Its 208cc engine is powerful enough for residential use but not overly large, keeping it manageable. While the product does not specify exact noise levels, gas pressure washers generally tend to be louder than electric ones, so it might not be the best choice if noise is a top priority.

Portability is a strong point with this model—the compact frame combined with large 10-inch pneumatic tires makes it fairly easy to move around rough surfaces despite its 64-pound weight. The 25-foot hose provides good reach without being cumbersome, and the inclusion of five quick-connect nozzles, including a soap nozzle, adds versatility for different cleaning jobs. The integrated detergent system helps with applying soap efficiently.

Being gas-powered means some maintenance such as fuel refilling and occasional engine upkeep is required, which might not suit everyone. Also, while the welded steel frame ensures durability, the unit is not the lightest, so carrying it over stairs or very uneven ground could be challenging. This pressure washer is well suited for homeowners needing a reliable, moderately powerful machine with decent portability and useful accessories, though quieter electric models might be preferred by those sensitive to noise.
