Description

Zoom on the Greenworks GPW1800

In summary, the Greenworks GPW1800 is a light duty pressure washer, that offers an all-around versatile cleaning experience, and also:

  • focused spot cleaning on hard, unpainted surfaces, accessing high spots, and efficiently eliminating stubborn stains
  • gentle cleaning for sensitive surfaces, and wide coverage cleaning with low pressure
  • applying detergents and cleaning agents, and rinsing off surfaces

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

Its axial cam pump, which utilizes a 13-amp universal motor, may deliver a pressure of up to 1800 PSI (almost 30 times more than a standard garden hose) and a flow of up to 1.1 GPM. Corresponding to these values is a cleaning power of 1980 Cleaning Units.

The GPW1800, an electric washer, swiftly activates via a simple ON/OFF switch, ensuring user-friendly startup. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

With its hand truck design, the Greenworks GPW1800 provides excellent maneuverability. The steel tubing frame's robustness ensures the assembly's longevity, maintaining stability and protecting internal components, even in the harshest environments. The foam-padded fixed handle adds to the GPW1800 convenience of transport, while offering a comfortable grip.

This unit's weight of 22.9 lbs makes it a breeze to carry around, perfect for on-the-go cleaning tasks. Complementing its lightweight frame, two 8" wheels are integrated, facilitating effortless transportation.

Main Features

The Greenworks GPW1800's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: Detergent storage is facilitated by the inclusion of a dedicated tank. Utilizing an automatic soap dilution mechanism, the Greenworks GPW1800 accurately mixes detergent to the defined ratio of 7:1, enhancing cleaning efficiency. When a soap nozzle is connected, the pressure washer takes the initiative to mix the detergent with the water flow automatically.
  • Pressure hose: When not in use, the unit allows for tidy storage of the included 20 ft high-pressure hose using a set of easy-to-use straps, ensuring convenient organization.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: Below, you'll find a table outlining the 5 included nozzles and their recommended surfaces.

  • With 1800 PSI, the Greenworks GPW1800 achieves a lower pressure when compared to similarly priced electric pressure washers within the $100-120 range. If you're seeking the strongest water stream, look no further than the Simpson CM60976, which delivers an impressive 2300 PSI.
  • In comparison to other devices in the above-mentioned price range, this washer and its 1.1 GPM (gallons per minute), has one of the lower GPM values. If you're looking for optimal debris removal capabilities, consider the Sun Joe SPX2688-MAX as one of the top choices in this price range, with a flow rate of 1.8 GPM.
  • The GPW1800 ranks as below average in terms of Cleaning Units, compared to electric devices in its price range, reaching only a value of 1980 CU (PSI X GPM).
