Description

Zoom on the Stanley SXPW3425

In a nutshell, the Stanley SXPW3425 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and fragile surfaces
  • use of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

Powered by an impressive 208 cc engine, its axial cam pump can deliver a pressure of 3400 PSI (around 57 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values). Combined, these values mean that the Stanley SXPW3425 has a cleaning power of 8500 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Shineray engine.

A fuel tank with a maximum capacity of 0.26 gallon is used to store gasoline.

Design & Handling

The wheelbarrow design of the Stanley SXPW3425 grants mobility and stability to the unit. The robust and sturdy steel frame offers longevity to the assembly. The handle adds to the SXPW3425 convenience of transport.

With a weight of 67 lbs, the unit can be easily maneuvered by most users. One of the largest contributors to its weight are its 208 cc Shineray engine and its steel frame. Since the SXPW3425 has a set of two 12" never-flat wheels, it is still easily maneuvered and manipulated.

Main Features

Along with the Stanley SXPW3425 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: A neat storage for the included 35 ft ⌀5/16" high-pressure hose is facilitated by a set of convenient hooks.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

Other Features

The specs of the Stanley SXPW3425

The Stanley SXPW3425

  • Dial-N-Wash®: Stanley’s Dial-N-Wash® is an adjustable pressure regulator that allows you to choose a desired pressure for your specific cleaning application. High, medium and low pressure settings can be switched between easily by a simple twist. Its design assures its compatibility with most pressure washer standard spray wands and standard guns with threaded fittings.
  • Onboard storage: Stay prepared for any job with Stanley SXPW3425's handy storage area, which allows you to neatly store any nozzles and accessories which you may need for the job.
  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation) and a thermal relief valve (which helps to prevent internal pump damage).
  • Accessories: On top of an owner's manual (opens in a new tab) and the usual documentation to get you swiftly started, the Stanley SXPW3425 also comes with spray gun, pressure hose, pressure regulator, wand and nozzle cleaner.
  • Emissions: The Stanley SXPW3425 is NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

    Stanley is no longer the company it once was I can tell ya that ! First off I bought this model in February of 2020 used it once did have some major problems getting it to start but finally it did. It did set over 6 months went to use it on a job started up pulled trigger and engine died instantly over and over again . I sent a warranty request to Stanley who referred me to dewalt who still has yet to give me any answers I’ve been playing this game for 6 weeks now and quite frankly this things is too new to be messing up already I just want my machine fixed and I feel like I’m being jerked around I even offered since they are owned by dewalt now to give this pos back and pay the difference for a dewalt washer which is much more expensive but as long as the machine works I don’t have a problem with it . Even after offering that they still have not responded . They will surely blame the slowness on covid and people need to get off the covid train already I’m sick of it affecting everything you got lazy people working from home now doing what they want and it’s sickening !

    + PROS: Looks real nice
    - CONS: Doesn’t work . And when it does start up it don’t have any pressure it’s a pos !
