With its featherlight weight of 19 lbs, this unit offers unparalleled ease of transport and handling. Its lightweight construction is partially attributed to its plastic frame. Although the GPW1602 doesn't feature wheels, its light weight renders them unnecessary.

Main Features

Along with the Greenworks GPW1602 itself, the package also includes a spray gun, a wand, a pressure hose, 2 nozzles and a detergent addition feature, which are discussed in further detail below.

  • Soap addition: Detergent is added to the water at the exit, by attaching the included foam cannon to the end of the gun. As the Greenworks GPW1602 does not include a soap dilution mechanism, it's essential to ensure proper detergent dilution before operating the pressure washer.
  • Pressure hose: When not in use, the unit allows for tidy storage of the included 20 ft ⌀1/4" high-pressure hose using a set of easy-to-use straps, ensuring convenient organization.
  • Spray gun and wand: A dedicated slot enables you to easily store the included classic ergonomic spray gun and its wand.

    Ease Of Use

    Very disappointed in this item. Found it easy to use. Found it to be lightweight. But after using it once a year to power wash my porch on the 4th year it would not start. It would briefly run and then stop. Very poor quality and very very poor customer service

    + PROS: Lightweight,worked fine while it was working, decent quality
    - CONS: After three times being used just to power wash my porch-once a year- it wouldn't turn on. It would turn on briefly and then turn off. Very poor customer service from the company
