Product Review · Pressure Washers · #8 Ranked
DeWalt DXPW3300-S
Gas 208cc residential washer, 3300 PSI at 2.4 GPM · Reviewed by Drew · amazon.com live, Sept 24 2026
Why it scored a 77
The DeWalt DXPW3300-S is a well-built residential gas washer: a DeWalt 208cc engine, an OEM Technologies axial cam pump with a thermal relief valve, a welded powder-coated steel frame and 10-inch pneumatic tires, which earns quality 82. The problem is price. At $429.00 it costs $80.00 more than the Westinghouse WPX3400, which has more pressure and flow, so value falls to 72. Satisfaction is 86 from 4.3 stars on 957 ratings. We could not confirm a warranty term from DeWalt, so warranty scores 55, our 1-year level.

Should you buy the DeWalt DXPW3300-S?
The DeWalt DXPW3300-S is for a buyer who wants pneumatic tires for gravel and grass and prefers the DeWalt build. At $429.00 it ranks #8 of 10 in our Pressure Washers category. The Westinghouse WPX3400 gives more pressure and flow for $349.00, and if you are spending more anyway, the Simpson PowerShot PS3228 adds a Honda engine, a triplex pump and a longer warranty.
Where it earns its score
- Pneumatic tires. 10-inch air-filled tires roll over gravel and grass more easily than hard plastic wheels.
- Thermal relief valve. It protects the pump from overheating when the engine runs with the trigger released.
- Sturdy frame. The welded steel frame has a powder-coated finish to resist rust.
- Complete kit. A 25-foot hose, 16-inch steel wand and five nozzles (0, 15, 25, 40 degree and soap) are included.
What to know first
- Warranty is the lowest factor at 55. The listing does not state a warranty term and we could not confirm one, so we scored it at our 1-year level.
- Priced above better specs. At $429.00 it trails the Westinghouse WPX3400 on pressure (3300 vs 3400 PSI) and flow (2.4 vs 2.6 GPM).
- Carbon monoxide and spray safety. Run it outdoors only, never in a garage or shed, even with the door open. Never point the spray at people or pets.
Our verdict
The DeWalt DXPW3300-S scores 77, a Fair Buy, with Satisfaction (86), Quality (82) and Features (80) as its best factors. Buy it if pneumatic tires and the DeWalt build matter to you, ideally when it is on sale. Otherwise the Westinghouse WPX3400 (85) delivers more pressure and more flow for $80 less, with a confirmed 3-year warranty.
