The reliable HONDA GX390 engine ensures easy start-up and consistent power, which is a significant plus for frequent use.

The 13-inch pneumatic tires enhance portability, allowing the washer to maneuver over various terrains with ease. The product comes with five quick-connect nozzle tips, offering versatility in the types of spray, which is beneficial for different cleaning tasks.

However, at 124 pounds, it is quite heavy, which might be a drawback for users who need to transport it frequently without assistance. The aluminum frame provides durability and resistance to corrosion but may require careful handling to prevent dents or damages. The professional spray gun with a safety lock-out is a nice addition, ensuring safety during operation. If you're looking for a high-performance pressure washer for decking and professional cleaning services, the SIMPSON Cleaning ALH4240 is a strong contender, though its weight and the need for fuel may be considerations to keep in mind.

The Greenworks 2700 PSI Pressure Washer is a solid choice for homeowners looking to clean decks, patios, fences, and driveways without the hassle of gas engines. It delivers a maximum pressure of 2700 PSI and a flow rate up to 2.3 gallons per minute, which is strong enough to handle most residential cleaning tasks effectively. Its electric power source means it's quieter, easier to start with a push-button, and requires less maintenance than gas models.

The package also comes with a foam cannon, which is helpful for applying soap evenly on surfaces like decking.

One downside is that while it covers a range of PSI and GPM for different nozzles, it may not match the raw power or mobility of gas washers for extremely tough stains or commercial use. This model suits residential users who want a reliable, easy-to-use electric pressure washer to keep outdoor surfaces clean without the noise and maintenance of gas engines.

The addition of dual detergent tanks is a nice touch, enabling users to switch between different cleaning solutions without hassle.
