Westinghouse ePX3100 Electric Pressure Washer

The Westinghouse ePX3100 is a corded electric pressure washer rated at 1900 PSI / 1.24 GPM — the practical working output that matters for car washing. The headline spec (2300 PSI / 1.76 GPM) is a max-peak figure achievable only at opposite ends of the pressure curve, not simultaneously. At rated output, cleaning units come to 2,356 — inside the 1,400–2,400 CU car-washing range. No community-measured PSI/GPM meter readings were found in available sources, so cleaning performance is scored provisionally based on rated spec and conservative motor-type adjustment. Motor type is listed as brushed/universal by pressurewasherdb.com; the manufacturer cites 13A amperage without claiming induction. The manual states conformance to UL 1776 and CSA C22.2 No.68, but an independent listing number was not confirmed in public databases as of May 2026. The M22 hose connection requires an adapter (or a compatible gun outlet) for most aftermarket foam cannons; at 1.24 GPM, foam generation is functional but not abundant. The 25-ft nylon braided hose is long enough to reach all four panels of a standard vehicle. The five-nozzle set includes 0°/15°/25°/Turbo/Soap but omits the 40° wide-fan nozzle; Turbo replaces it for many rinse tasks. The Total Stop System auto-shutoff protects the pump during foam-soak idle periods.

The ePX3100 fits the occasional car washer — once or twice a month — who wants a compact, lightweight unit (19 lbs) with enough output for a regularly washed daily driver and basic foam cannon capability. The anti-tipping wheeled base, 35-ft GFCI cord, and onboard soap tank add convenience at the price point. Skip it if foam cannon performance is a priority: the M22 fitting and 1.24 GPM rated output mean foam quality will be marginal compared to units with standard 1/4" QC fittings and 1.4+ GPM flow. Also skip it for high-frequency or commercial-use: a universal-motor unit at this tier is not rated for sustained heavy-duty sessions. The higher-PSI ePX3100v variant (explicitly uses a universal motor per manufacturer spec) or a confirmed induction-motor unit better suits year-round intensive use.

The ePX3100's manual cites conformance to UL Standard 1776 and CSA C22.2 No.68, which is a manufacturer conformance declaration — an independent NRTL listing number was not confirmed in the UL Product iQ or ETL certification directories as of May 2026. No active CPSC recall was found for this model. The unit is corded electric with a GFCI plug, appropriate for wet outdoor use. Dispose of at end of life via a municipal e-waste program (Best Buy drop-off, municipal hazardous waste event) — there is no lithium battery to manage separately. The ePX3100 is an electric-only model; Westinghouse also sells gas-powered pressure washers, which are not covered by this review.
