Power and Performance

The Greenworks 2100 PSI is a formidable electric pressure washer with a maximum pressure of 2100 PSI and a flow rate of 1.2 GPM. This makes it suitable for various cleaning tasks, including driveways, patios, and vehicles. In contrast, the McKillans Foam Cannon does not provide pressure washing on its own but enhances the cleaning power of existing pressure washers by producing a thick foam that clings to surfaces, allowing for a more effective wash. For users looking for raw cleaning power, the Greenworks pressure washer stands out.

Design and Usability

The Greenworks 2100 PSI features a compact design with a telescoping handle and multiple grab points for easy transportation. It includes internal storage for its accessories, such as nozzles and a soap applicator, facilitating a streamlined experience. Conversely, the McKillans Foam Cannon boasts a wide mouth design that allows for easier soap dilution, preventing spills and instability during use. While both products are designed with user-friendliness in mind, the Greenworks unit’s multifunctionality gives it an edge in overall usability.

Cleaning Efficiency

With its adjustable nozzles and powerful PSI, the Greenworks 2100 PSI is built for efficiency in tackling medium-duty cleaning projects. The included turbo nozzle, along with standard nozzles, allows for a tailored cleaning experience, making it effective for various surfaces. The McKillans Foam Cannon, while not a standalone cleaning tool, excels in providing thick foam that enhances dirt removal and protects your vehicle’s paint from swirl marks. For those focused on detailed car washes, the foam cannon adds significant value to the cleaning process.

Accessories and Compatibility

The Greenworks 2100 PSI comes equipped with multiple accessories, including a soap nozzle, turbo nozzle, and various spray angles (25° and 40°), enhancing its versatility for different cleaning tasks. The McKillans Foam Cannon is designed to be compatible with both electric and gas-powered pressure washers and includes a 1/4 quick connector for easy attachment. While the Greenworks model offers more built-in accessories, the McKillans Foam Cannon complements existing setups effectively.

Price Comparison

The Greenworks 2100 PSI is priced at $164.83, while the McKillans Foam Cannon is considerably more affordable at $49.98, making it about 70% cheaper. This price difference reflects the broader capabilities of the Greenworks pressure washer compared to the McKillans Foam Cannon, which primarily serves as an accessory. Depending on your cleaning needs, the price of the Greenworks unit may be justified by its performance and versatility.
