About This Product

Perform professional tasks with the PressuReady Gas-Powered Cold-Water Pressure Washer (CETA certified* 3400 psi @ 2.5 gpm). It comes equipped with 5 stainless steel quick connect nozzles, built to handle demanding jobs. Squeeze the spray-gun trigger to activate the PressuReady Technology battery-operated electric starting system with no need to adjust the choke or pull the recoil rope. To save on fuel and reduce noise, the unit shuts off after a few seconds of inactivity. When you're ready to get back to work just squeeze the trigger. The battery-operated PressuReady Smart Control panel is designed with a built-in LED diagnostic screen. This screen indicates the specific mode the pressure washer is in, such as ready-mode and water flow. And, it alerts you with fault codes like no fuel and low battery. The battery compartment is water-resistant and accepts 20V MAX* batteries and is compatible with DEWALT FLEXVOLT batteries.

                      Actually Rudy, the DXPW3400PR is the only pressure washer in the world with auto shut down - the unit shuts off after a few seconds of inactivity. When you're ready to get back to work just squeeze the trigger. Thanks for the question.

                        Regarding the battery. In the Q&A there are conflicting answers. For example: 10-25-2020 Support says battery and charger included. Most answers say 20V Max 4ah or higher. Will a DCB205 XR 5ah work? Is it too big to fit? Where does it attach?

                              Bad quality
                              Less than a year and valve is leaking terrible, is not worth it to spend over $300 for this dewalt 3400 psi pressure washer.

                                  [This review was collected as part of a promotion.] We got this pressure washer to use around the house and it is perfect for that. We had been talking about getting one for awhile and made the decision to get one and now we have all kinds of projects we want to work on.

                                      Do not buy this pressure washer it’s junkHutch
                                      Got this pressure washer in April and got two uses out of it, was told that I couldn’t take it back to Home Depot that it would have to go through Dewalt, I get in touch with Dewalt and it’s like they don’t care, I’ve been calling and emailing them and always get past off. Here it is going into August and still no one has gotten in touch with meI need a pressure washer now and they got me waiting waiting and waiting. It’s like they’re trying to wait until the warranty runs out so they can say I’m sorry it’s yours actually I’m sorry I bought this Dewalt pressure washer.

                                        The worse pressure washer.
                                        Purchased it when it’s was almost $700. used it two times and pump stopped working, called Dewalt and the advise me to take to service center, called the service center too many times to get an answer about it, after almost three months they answered me and they said Dewalt not covered under the warranty and not worth to fix it. Called Dewalt customer service again and they don’t let me talk with warranty department, saying the service center talk with them.

                                          Had the washer for 3 years. Used 5 times and stopped working. Three pistons within the pump began cracking and chipping. Not covered under warranty. Brought to a certified service center and was told, “Yeah dewalt washers are junk. They bought some company and slap their name on it. You’re better off with a cheap electric one and just trashing it when you’re done honestly.” Very disappointed, been a Dewalt loyalist for years.
