DeWalt vs Westinghouse Pressure Washer: Gas and Electric Compared
Quick answer: On gas models, GasWasherHQ calls the Westinghouse WPX3400 the best value at about $349 and the DeWalt DXPW3400 the most user-friendly at about $729. The pressure figures are almost identical. We have not tested them ourselves.
Last updated: October 2026. DeWalt and Westinghouse both sell gas and electric pressure washers, but their pricing strategies differ. This comparison uses GasWasherHQ, Bob Vila, TechGearLab and RJP Hotsy. RJP Hotsy is a vendor with its own brand, and GasWasherHQ is a small blog, so we flag them. We have not tested any of these machines ourselves.
How do the gas models compare?
| Feature | Westinghouse WPX3400 | DeWalt DXPW3400 |
|---|---|---|
| PSI / GPM | 3,400 / 2.6 | 3,400 / 2.5 |
| Price (GasWasherHQ) | About $349 | About $729 |
| Engine | 212cc | 208cc |
| Pump | Axial cam | Axial cam |
| Warranty | 3 years | Not stated in this source |
| Starting | Pull start | Battery-assisted (battery about $50 to $80 extra) |
GasWasherHQ’s verdicts: Westinghouse is best value for most homeowners, and DeWalt is the most user-friendly.
How do the electric models compare?
| Model | PSI / GPM | Price | Warranty |
|---|---|---|---|
| DeWalt DWPW2100 | 2,100 / 1.2 | About $300 | 3 years (Pro Tool Reviews) |
| DeWalt DWPW3000E (RJP Hotsy) | n/a / 1.1 | $450 to $500 | 1 year |
| Westinghouse WPX3000E (RJP Hotsy) | n/a / 1.76 | $350 to $400 | 3 years |
RJP Hotsy’s verdict is that both brands have significant flaws, with DeWalt’s being low flow and Westinghouse’s being durability.
What did labs measure?
TechGearLab measured the Westinghouse WPX3200 at 2,600 PSI and 2.3 GPM (5,980 cleaning units) and 63.6 lb, below the 3,200 PSI and 2.5 GPM rating. It also recorded 83.2 dB. That does not make it a poor performer, since it earned an Editors’ Choice, but it shows why measured results matter.
How do price and warranty compare?
Westinghouse charges roughly half as much for a similar gas spec, with a 3-year warranty. DeWalt charges for ease of starting and compact storage. Bob Vila lists the electric DWPW2100 at 2,100 PSI, 1.2 GPM and 24 lb.
Choose Westinghouse if…
You want the lowest price and longer warranty. See our Westinghouse review.
Choose DeWalt if…
You want easy starting and compact storage and can pay roughly double. See our DeWalt review.
What matters more than the badge?
Both gas models use axial pumps rated for a few hundred hours, so treat either as a homeowner tool. If you plan heavy use, look at triplex pumps in our pump guide. Check the engine, noise and weight, and confirm the exact model code.
A simple decision checklist
- Set a budget for the machine and accessories.
- Decide whether easy starting justifies the price gap.
- Compare warranty by component.
- Confirm hose length and fittings.
- Buy from a seller with a clear return policy.
Are there other options?
Yes. Simpson makes durable triplex models, as our Simpson vs DeWalt guide explains, and our gas guide lists more.
How much does starting matter?
Gas pressure washers use a pull cord, and many owners dislike them. DeWalt’s battery-assisted start needs a DeWalt 20V or FlexVolt battery, which GasWasherHQ prices at about $50 to $80 extra if you do not own one. Westinghouse uses a standard pull start. If you have shoulder problems, or store the machine for months between uses, easier starting can be worth the extra money. Fresh fuel and regular maintenance help either machine start reliably.
How much will upkeep cost?
Sources put upkeep for a home gas washer at roughly $30 to $50 a year for oil, fuel stabiliser and a spark plug. Both brands need the same care, so upkeep should not decide the choice. What matters more is how often you use the machine and how you store it. Follow our winterizing guide to protect the pump.
Is Westinghouse durability a concern?
RJP Hotsy says Westinghouse’s flaw is durability, while Power Tool Hunter notes a heat-sensitive hose and flimsy gas filter on the WPX2700. Those are inexpensive parts to replace, but inspect them each season. A three-year warranty helps reduce the risk for homeowners.
Which should you buy for which job?
For driveways, decks and fences on a budget, the Westinghouse gas model gives similar pressure for less money. For occasional use where easy starting and neat storage matter, DeWalt is more convenient. For small car and patio jobs, consider an electric model instead of gas at all.
