Greenworks GPW1704 Questions and Answers


#1 Does this auto shut off when the trigger is not pulled?

The unit will go into resting mode if the trigger is not pulled. However, it is not completely off. If you are not using it for more than 10 minutes then you should turn the unit off.

#2 How much wattage does this pressure washer use? I want to plug it in a mobile generator.

This pressure washer is measured at 1560 watts.

#3 Can you adjust the pressure on the machine? Is 17 psi the max and can it be lowered?

The pressure cannot physically be adjusted. However, please keep in mind that this unit can be used with a variety of spray tips that affect pressure and make it suitable for a variety of different applications.

#4 Dies greenworks make an extension pole for the 1700 psi washer? Need to reach high places on siding of house.

We do not offer extension wands for our pressure washers. While we do not offer these products, they can be purchased from other brands that may be compatible. The extension wand would have to be connected to our wand using a 1/4" quick connect fitting to the end of the existing wand, however, please know that the pressure may be affected as the units were not technically designed to be used with an extension wand. You could also try 1/4" quick connect second-story nozzles in lieu of an extension wand.
