Westinghouse

The Westinghouse pressure washer lineup at a glance

All three models are corded electric units built around the same basic formula: a 25-foot hose, a 5-piece nozzle set (0°, 15°, 25°, a turbo nozzle in place of the usual 40° wide-fan tip, and a soap nozzle), an onboard soap tank, and an auto-shutoff pump (Westinghouse calls it TSS, Total Stop System) that cuts the motor when the trigger is released. Where they differ is rated pressure and flow:

Higher rated PSI does not automatically mean a better wash: cleaning power is a function of PSI and GPM together, and all three sit in a similar cleaning-units range once you multiply the two out. The ePX3100 trades some peak pressure for slightly more flow, which matters more than the PSI number for rinsing suds off quickly.

Is a Westinghouse pressure washer good for washing a car?

For the size and budget these sit in, yes, with one caveat worth knowing before you buy. All three run a 25-foot hose that reaches around a mid-size sedan without repositioning, an onboard soap tank for pre-soak or two-bucket work, and a nozzle set that covers everything from a wide rinse to a focused turbo tip for stuck-on grime. The ePX3500's anti-tipping 4-wheel base is a genuine differentiator over upright competitors that tip over when the hose gets pulled at an angle — a common annoyance with cheaper units.

The caveat: none of the three currently carry an independently verified electrical-safety listing (UL or ETL) in the public certification databases. The ePX3500 and WPX3000e cite only a factory functional-test claim, and the ePX3100's manual states it "conforms to" UL 1776 and CSA C22.2 No. 68, which is a conformance declaration from the manufacturer rather than a listing number you can look up. That is a fact worth having for a corded tool used around water, not a reason to avoid the brand outright — plug into a GFCI-protected outlet as you would with any electric pressure washer, corded or not.

Foam cannons and accessories

Westinghouse sells a matched accessory line — foam cannons, surface cleaners, and hose-extension kits — built for its own pressure washers. The gun-to-hose connection across the lineup is M22, standard for the category, and the gun-to-accessory outlet is a 1/4" quick-connect on the ePX3500 and WPX3000e (confirmed against Westinghouse's own foam-cannon accessory). All three sit at a rated GPM between 1.1 and 1.24, which is enough flow to run a foam cannon but on the low side for the thickest snow-foam look — expect serviceable, not exceptional, foam volume compared to a gas unit or a higher-GPM electric.

FAQ

Are Westinghouse pressure washers any good? For occasional car washing and around-the-house use, yes — the lineup covers a useful PSI/GPM range, ships with a full nozzle set and onboard soap tank, and (on the ePX3500) an anti-tipping base that upright competitors often lack. The one gap to know about is certification: none of the three currently carry an independently verified UL or ETL listing, only a factory-test claim or a manufacturer conformance declaration.

What is the difference between the Westinghouse ePX and WPX series? Both are corded electric pressure washers built on the same nozzle-set-and-soap-tank formula; the naming does not map to a strict pressure tier. The WPX3000e rates highest on PSI (2,600) with a claimed induction motor, the ePX3500 rates 2,000 PSI with a confirmed anti-tipping base, and the ePX3100 is the entry model at 1,900 PSI with slightly more rated flow (1.24 GPM).

Do Westinghouse pressure washers work with foam cannons? Yes, with a caveat on volume. The gun outlet is a 1/4" quick-connect fitting on the ePX3500 and WPX3000e, which is what most foam cannons expect, but the rated flow (1.1–1.24 GPM) sits at the low end of what produces thick, clingy foam. You'll get usable pre-soak foam, not the deepest snow-foam look you'd see from a higher-GPM unit.

Is Westinghouse the same company as Westinghouse Electric? No, not directly. The outdoor power equipment line trades on the brand recognition of the century-old Westinghouse Electric Corporation, but modern pressure washers, generators, and lawn equipment are manufactured and imported under license by a separate outdoor-power business, not built by the original industrial entity.

Where can I buy a Westinghouse pressure washer? The ePX-series and WPX-series are distributed widely through Home Depot, Lowe's, Walmart, and Amazon, and carry a 3-year limited residential warranty.
