Greenworks 2100 PSI Pressure Washer
Score: 72/100Rankings

The Greenworks 2100 PSI Compact Electric Pressure Washer is a corded unit designed for medium-duty residential cleaning tasks, featuring a 13Amp universal motor and a 25-foot hose with a reel. Its key strength is the PWMA certification and compact storage design, making it convenient for home use. However, it is heavier than cordless options and users report it feels weaker than gas models. It is best suited for homeowners prioritizing electric convenience and ease of use over heavy-duty power.

The Kärcher K 2 Horizontal is a specialized accessory wand designed for safe, versatile vehicle cleaning with K1 and K2 Entry washers. Its key strength is the infinitely variable pressure adjustment, which eliminates the need to swap nozzles and protects paint. However, its compatibility is strictly limited to specific lower-power models, making it unsuitable for heavy-duty tasks or users with gas-powered units.
