Westinghouse ePX3100 Electric Pressure Washer — 2300 Max PSI, 1.76 GPM, 4-Wheel Anti-Tip

Overall Electric Washer (Won't Tip Over)#1

WestinghouseMid-Range

Westinghouse ePX3100 Electric Pressure Washer — 2300 Max PSI, 1.76 GPM, 4-Wheel Anti-Tip

Our #1 overall electric pick uses four 360° quick-lock wheels and a low center of gravity to resist tipping, delivering 2,300 max PSI (1,900 rated) and up to 1.76 GPM with a 20 oz onboard soap tank.

PSI · GPM · Cleaning Units2,300 Max PSI · 1.76 Max GPM · 1,900 PSI / 1.24 GPM rated

Motor / Engine & Pump120V electric motor · Auto-stop pump

Hose, Nozzles & Frame25 ft nylon-braided hose · 5 QC nozzles (0°, 15°, 25°, turbo, soap) · 20 oz soap tank

Weight & Power Source19 lbs · 16.5" tall · 4 × 360° wheels

Watch out for: Rated output is 1,900 PSI and 1.24 GPM—well below the max figures—so heavy concrete stains take longer than with a gas washer.

Confused by specs?

Ignore inflated 'Max PSI' stickers. Four mechanical specs tell you how fast a pressure washer cleans, whether it will tip over in your driveway, and how many seasons the pump will last.

✓Cleaning Units (CU = PSI × GPM). PSI breaks grime loose; GPM flushes it away. A 2,100 PSI × 1.76 GPM washer (3,696 CU) cleans faster than a 2,400 PSI × 1.1 GPM unit (2,640 CU).
✓Brushless Induction vs. Universal Motors. 120V brushless induction motors (Greenworks 2300, Sun Joe MAX) run quieter and last longer than high-RPM brushed motors.
✓Axial Cam vs. Triplex Plunger Gas Pumps. Axial cam pumps (SIMPSON MegaShot) suit 30-hour/year homeowners; AAA triplex plunger pumps (PowerShot PS3228) are rebuildable for pro duty.
✓Low-Center-of-Gravity Anti-Tip Frames. Tall 2-wheel plastic carts tip over when you tug the hose; 4-wheel low-profile bases (Westinghouse ePX3100) or compact units (Kärcher K1700) stay planted.

Questions

What is more important on a pressure washer: PSI or GPM?

Both matter together—multiply PSI × GPM to get Cleaning Units (CU). PSI (pounds per square inch) is the stripping force that breaks grime loose, while GPM (gallons per minute) is the water volume that flushes dirt away. For washing cars, you actually want moderate pressure (1,500–2,100 PSI) and higher GPM (1.5–1.76+ GPM) so you don't damage paint.

Why do upright electric pressure washers keep tipping over?

Many older 2-wheel upright carts mount the heavy motor high off the ground and connect the high-pressure hose near the top handle. Every time you tug the hose, leverage pulls the cart onto its face. Choosing a 4-wheel low-center-of-gravity unit (Westinghouse ePX3100), a compact Kärcher K1700, or a flat jobsite cage (DEWALT DWPW2100) solves tipping completely.

Do I need a gas pressure washer or will a 120V electric model clean my driveway?

A 120V electric pressure washer (2,000–2,300 PSI) will clean patios, decks, siding, cars, and small walkways well using a 15° or turbo nozzle. However, if you have a large two-car concrete driveway or want to spin a 15-inch steel surface cleaner (SIMPSON 80165) at full speed, a 3,100 PSI / 2.3 GPM gas washer (SIMPSON MegaShot MS61222-S) finishes the job in less than half the time.
