Description
Zoom on the Greenworks GPW1800
The Greenworks GPW1800, a light duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- cleaning of painted or delicate surfaces
- application of detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
Using a 13 amp motor, its axial cam pump delivers a pressure of up to 1800 PSI (roughly 30 times more than a standard garden hose) and a flow of up to 1.1 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 1980 Cleaning Units.
The GPW1800 is an electric pressure washer and thus, can be easily started by an ON/OFF switch. 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 great mobility. The robust and sturdy steel tubing frame offers longevity to the assembly. The foam-padded fixed handle adds to the GPW1800 convenience of transport, while offering a comfortable grip.
Standing at only 26.2 lbs, this model can be carried around very easily. A set of two 8" wheels also improves the ease of transport of the device.
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 ensured by a dedicated tank. The automatic soap dilution mechanism of the Greenworks GPW1800 will dilute the detergent with a 7:1 ratio. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: The included 20 ft high-pressure hose can be neatly stored on the unit when idle thanks to a set of easy-to-use straps.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
