Pressure washers have become essential tools for homeowners, contractors, and property managers who want to save time, cut labor, and achieve professional-level cleaning results. While electric pressure washers are compact and quiet, they rarely deliver the raw cleaning power needed for heavy-duty tasks like stripping oil stains, preparing surfaces for painting, or blasting mildew off siding.
That’s where gas-powered pressure washers come in. And few names inspire as much confidence as DeWalt — a brand synonymous with durability, innovation, and pro-grade tools.
The DeWalt DXPW3425E-S is one of their standout models, built to deliver:
- 3400 PSI at 2.5 GPM cleaning performance,
- A 208cc OHV engine with electric start for convenience,
- A rugged axial cam pump,
- A heavy-duty steel frame,
- And a full set of quick-connect nozzles for every cleaning scenario.
In this in-depth review, we’ll cover everything you need to know about the DXPW3425E-S: from specs and features to real-world performance, pros and cons, comparisons, buying tips, and FAQs.
- Premium Residential Performance: Easy-to-assemble and easy-to-start with an electric-start DeWalt 208cc premium residential engine, this power washer is great for cleaning decks, patios, outdoor furniture, siding, and prepping home exteriors for painting

Key Features (Deep Dive)
1. 3400 PSI at 2.5 GPM Cleaning Power
The DXPW3425E-S offers the ideal blend of pressure and water flow. At 3400 PSI, it can cut through:
- Stubborn oil stains on driveways.
- Mold and algae on siding.
- Caked-on mud from farm equipment.
- Paint prep jobs for decks and fences.
Meanwhile, the 2.5 GPM flow rate ensures you move enough water to rinse away debris quickly. This balance is critical — too much PSI without sufficient GPM means you’ll strip surfaces but not rinse effectively.
2. 208cc Engine with Electric Start
Most gas pressure washers require pulling a recoil cord to start — which can be frustrating. The DeWalt DXPW3425E-S includes a push-button electric start, so firing it up is as easy as starting your car.
A recoil backup ensures reliability even if the battery is low. This feature alone saves time, reduces hassle, and makes the washer more user-friendly for all skill levels.
3. Axial Cam Pump
The pump is the heart of a pressure washer. The DXPW3425E-S uses an axial cam pump, designed for:
- Lower maintenance than triplex pumps.
- Reliable performance for residential and light commercial use.
- Compact design that reduces weight and cost.
While it won’t last as long as a commercial triplex pump under daily abuse, it’s more than enough for weekly heavy-duty use.
4. Five Quick-Connect Nozzles
Versatility is key. The included nozzle set covers every application:
- 0° (Red): Ultra-focused stream for deep stains.
- 15° (Yellow): Paint stripping, concrete cleaning.
- 25° (Green): General cleaning of siding, decks, and driveways.
- 40° (White): Gentle rinse for cars and delicate wood.
- Soap (Black): For detergent application.
Switching nozzles takes seconds, giving you the right spray pattern for any surface.
5. 25-Foot Non-Marring Hose
The 5/16 in. × 25 ft hose is kink- and abrasion-resistant. While longer hoses (35–50 ft) are more convenient for large properties, the included 25 ft length is ideal for most home and small business jobs.
6. Heavy-Duty Steel Frame & Pneumatic Wheels
At nearly 90 lbs, the DXPW3425E-S is no featherweight. But the welded steel frame ensures durability, while the 10” pneumatic tires make it easy to roll across gravel, grass, or uneven terrain.
Performance Review
Startup Experience
The electric start system is the hero here. With one push, the 208cc engine roars to life — far easier than pull-starting a cold gas engine. If the battery runs low, the recoil backup ensures you’re never stuck.
Cleaning Results
- Concrete Driveways & Patios: Removes years of dirt, grease, and mildew.
- Wood Decks & Fences: With the right nozzle, it restores wood grain without splintering.
- Vehicles & Boats: Safe with the 40° nozzle + detergent setup.
- Siding & Brick: Blasts away algae and mold, making exteriors look new.
- Farm & Construction Equipment: Cuts through mud, grease, and oil efficiently.
Noise & Vibration
As a gas-powered washer, it’s louder than electric models, but vibration is manageable thanks to the sturdy frame. Noise is typical for its class — hearing protection is recommended for extended use.
Portability
At ~90 lbs, it’s heavier than residential units. But the 10” wheels and balanced frame design make it easy to maneuver, even across uneven ground.
