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. These values correspond to 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 steel tubing frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the GPW1800 convenience of transport, while offering a comfortable grip.
Since the unit weighs only 22.9 lbs, it is very easily carried around. On top of its light weight, the transportability and ease of use of this model is further improved by the addition of two 8" wheels.
