Westinghouse Electric Pressure Washer Guide: How Much PSI Do You Need?
As Amazon Associates, we earn from qualifying purchases. This means we may receive a small commission at no extra cost to you if you click through and make a purchase.
Westinghouse is a familiar name in home power equipment, and its electric pressure washers cover everything from small car-washing units to cart-style machines built for driveways and siding. For a first-time buyer, the challenge is not finding one but choosing the right power level, because the lineup spans from 2100 to 3400 max PSI and the model names (WPX, ePX, v, e) do not explain much on their own.
These six models differ mainly in pressure, water flow, motor type and body style: two large cart-style WPX machines, three compact four-wheel or upright ePX units, and one handheld-style ePX with a carry handle. Below we explain PSI, GPM and brushless motors in plain words, then walk through each model so you can match it to your jobs.

Westinghouse WPX3000e Electric Pressure Washer
Best for: Driveways and siding on a steel-frame cart
Pros
- 3000 max PSI
- 35 ft GFCI cord
- 10-inch never-flat wheels
- M22 accessory fittings
Cons
- Heaviest here at 36.8 pounds
- Induction, not brushless
The Westinghouse WPX3000e Electric Pressure Washer is a cart-style machine on a steel frame with 10-inch never-flat wheels. It delivers 3000 max PSI and 1.76 max GPM, with 2600 rated PSI and 1.1 rated GPM. PSI (pounds per square inch) is how hard the water hits; GPM (gallons per minute) is how much water flows. “Max” figures are peak numbers measured at different settings, while “rated” figures describe steady working output, so rated numbers are the fairer comparison between models.
It runs on a heavy-duty 120V induction motor, a traditional motor type known for durability, with an axial 3-piston auto-stop pump. Auto-stop means the pump pauses when you release the trigger. You get a 25 ft super-flex hose, a metal spray gun and wand, five quick-connect nozzles (0°, 15°, 25°, soap and turbo), a 0.45 gallon soap tank and a 35 ft GFCI cord, which is a safety cord that cuts power if it detects a fault. It accepts M22 accessories such as surface cleaners and foam cannons. The unit weighs 36.8 pounds and measures 22.6 x 25.6 x 36.6 inches.
This suits homeowners with long driveways, decks or siding who want real power and do not mind a bigger machine. If you need more power still, the WPX3400e steps up; if storage is tight, the ePX models are far smaller.
Westinghouse ePX3500 Electric Pressure Washer for Compact Storage
Westinghouse
Westinghouse ePX3500 Electric Pressure Washer, 2500 Max PSI 1.76 Max GPM with Anti-Tipping Technology, Onboard Soap Tank, Pro-Style Steel Wand, 5-Nozzle Set, for Cars/Fences/Driveways/Home/Patios
Price and specifications are read from the Amazon product page and can change.
Westinghouse ePX3500 Electric Pressure Washer
Best for: Small storage spaces and car washing
Pros
- 19 pounds, 16.5 inches tall
- Anti-tipping four-wheel design
- 5 nozzles plus soap tank
Cons
- 2500 max PSI, less for concrete
- Description names a different model
The Westinghouse ePX3500 Electric Pressure Washer is a low, four-wheel unit that stands 16.5 inches tall and weighs 19 pounds. It delivers 2500 max PSI and 1.76 max GPM, with 2000 rated PSI and 1.2 rated GPM. Its four quick-lock wheels steer 360 degrees, and Westinghouse says the low center of gravity is designed to prevent tipping when you tug on the hose.
It includes a pro-style steel extendable 17.5-inch wand, five quick-connect nozzles (0°, 15°, 25°, turbo and soap applicator), an easy-coil nylon braided 25 ft hose and a 20 ounce onboard soap tank. The pump auto-stops when the trigger is released. Coverage is a 3-year limited warranty. One oddity: the product description refers to the ePX3100 by name while quoting the ePX3500’s figures, so rely on the title and features.
This model suits apartment dwellers, car owners and anyone who stores tools in a small closet but still wants enough pressure for patios and fences. For heavily stained concrete, the WPX models give more headroom.
Westinghouse WPX3400e Electric Pressure Washer for the Toughest Jobs
Westinghouse
Westinghouse WPX3400e Electric Pressure Washer, 3400 Max PSI and 2.0 Max GPM, Brushless Motor, Onboard Soap Tank, Spray Gun and Wand, 5 Nozzle Set, for Cars/Fences/Driveways/Homes/Patios/Furniture
Price and specifications are read from the Amazon product page and can change.
Westinghouse WPX3400e Electric Pressure Washer
Best for: Biggest jobs needing the most power
Pros
- 3400 max PSI, 2.0 max GPM
- Brushless motor
- Half-gallon soap tank
Cons
- Larger cart-style frame
- Hose length listed inconsistently
The Westinghouse WPX3400e Electric Pressure Washer is the most powerful model here, with 3400 max PSI and 2.0 max GPM, plus 3000 rated PSI and 1.1 rated GPM. It uses a 120V true brushless motor. A brushless motor has no small carbon brushes rubbing inside it, which generally means less wear and more efficient running than a brushed motor.
Like the WPX3000e, it has a steel frame, 10-inch never-flat wheels, a 35 ft GFCI cord, an axial 3-piston auto-stop pump, a metal spray gun and wand, five nozzles and M22 accessory compatibility. There are two inconsistencies: the features describe a 25 ft hose and a half-gallon soap tank, while the specs list a 23 ft hose and the description says 0.45 gallons. Dimensions are 25.9 x 19.3 x 37.4 inches; weight is not listed.
This is the pick for people cleaning brick, stone and concrete across a large property. For occasional car washes it is more machine than you need. If you want to compare other brushless electric options, see our electric pressure washer roundup.
Westinghouse ePX3100v Electric Pressure Washer for Grab-and-Go Cleaning
Westinghouse
Westinghouse ePX3100v Electric Pressure Washer, 2100 Max PSI 1.76 Max GPM, Built-in Carry Handle, Detachable Foam Cannon, Pro-Style Steel Wand, 3-Nozzle Set, for Cars/Fences/Driveways/Home/Patios
Price and specifications are read from the Amazon product page and can change.
Westinghouse ePX3100v Electric Pressure Washer
Best for: Carry-anywhere washing for cars and patios
Pros
- 6 pounds with carry handle
- Detachable foam cannon
- Nylon braided hose
Cons
- 2100 max PSI
- Only 3 nozzles, 20 ft hose
The Westinghouse ePX3100v Electric Pressure Washer is built to be carried. It weighs 17.6 pounds and has a built-in handle, which the description calls handheld. It delivers 2100 max PSI and 1.76 max GPM, with 1800 rated PSI and 1.2 rated GPM.
Instead of an onboard soap tank, it comes with a detachable foam cannon, a bottle that fits on the wand and turns detergent into thick foam, popular for washing cars. It has an easy-coil nylon braided 20 ft hose, a pro-style steel wand and a 3-nozzle set, plus auto-stop and a 3-year limited warranty.
This suits car lovers and people with small patios, balconies or outdoor furniture who want to carry the washer around. The shorter hose and three nozzles give way to the ePX3500 or ePX3100 for bigger areas.
Westinghouse ePX3050 Electric Pressure Washer for Upright Compact Use
Best for: Compact upright unit with foam cannon
Pros
- Foam cannon included
- 35 ft GFCI cord
- M22 accessory fittings
Cons
- 2100 max PSI
- Weight listed inconsistently
The Westinghouse ePX3050 Electric Pressure Washer matches the ePX3100v on paper for power, at 2100 max PSI and 1.76 max GPM, with 1800 rated PSI and 1.2 rated GPM. Its shape is different: a low 26-inch upright profile with 5-inch never-flat wheels and a 35 ft GFCI cord.
It comes with a foam cannon, a 20 ft abrasion-resistant super-flex hose, a spray gun and wand, and three quick-connect nozzles (15°, 25° and turbo), and it accepts M22 accessories. It uses a 120V motor with a maintenance-free axial cam pump with auto-stop. Weight is listed as 17 pounds in the specs but 14 pounds net in the description; dimensions are 12.4 x 11.3 x 25.8 inches.
This suits buyers who want a light machine that rolls rather than carries, with a long cord for reaching the far side of a car. Anyone who wants a 0° nozzle for stubborn spots should look at the five-nozzle models instead.
Westinghouse ePX3100 Electric Pressure Washer for Balanced Everyday Power
Best for: Balanced mid-power pick for patios and decks
Pros
- 2300 max PSI
- Anti-tipping four-wheel design
- 20 oz soap tank
Cons
- Specs mislabel part number
- Weight listed two ways
The Westinghouse ePX3100 Electric Pressure Washer shares the ePX3500’s compact 16.5-inch four-wheel body with anti-tipping design, but with 2300 max PSI and 1.76 max GPM, and 1900 rated PSI and 1.24 rated GPM.
It includes the same 17.5-inch extendable steel wand, five quick-connect nozzles (0°, 15°, 25°, turbo and soap applicator), an easy-coil nylon braided 25 ft hose and a 20 ounce soap tank, with auto-stop and a 3-year limited warranty. The features say 19 pounds while the specs list 9 kg (about 20 pounds), and the specs give a manufacturer part number of ePX3050, which looks like a listing error.
This suits first-time owners who want one compact washer for cars, decks and patio furniture. If you mostly clean concrete, the ePX3500 or a WPX model gives more pressure.
How to Choose the Right Westinghouse Electric Pressure Washer
Start with your main job. Cars, bikes and patio furniture need around 1800 to 2000 rated PSI, which the ePX3100v, ePX3050 and ePX3100 cover. Decks, fences and patios benefit from the ePX3500’s 2000 rated PSI. Driveways, siding and stubborn stains call for the WPX3000e (2600 rated PSI) or the WPX3400e (3000 rated PSI).
Next, think about flow. Higher GPM rinses faster. Most models list 1.76 max GPM; the WPX3400e lists 2.0.
Then consider storage and carrying. The WPX machines are cart-style and heavier; the ePX units are compact, and the ePX3100v has a carry handle.
Finally, check accessories. Soap tanks suit general cleaning; foam cannons suit car washing. The WPX3000e, WPX3400e and ePX3050 list M22 fittings for add-ons. For another take on compact corded models, our electric power washer guide covers more choices.
FAQ
How much PSI do I need to wash a car?
Around 1800 to 2000 rated PSI with a 25° or soap nozzle is typical for cars. The ePX3100v, ePX3050 and ePX3100 sit in that range.
What is the difference between max and rated PSI?
Max PSI is the peak pressure; rated PSI is steady working output. Westinghouse lists both, and rated numbers make fairer comparisons.
Is a brushless motor worth it?
Brushless motors avoid wearing brushes and generally run more efficiently. In this lineup, only the WPX3400e lists a brushless motor.
What does GFCI mean on a pressure washer cord?
GFCI stands for ground fault circuit interrupter, a safety feature that cuts power if electricity leaks, important around water. The WPX3000e, WPX3400e and ePX3050 list 35 ft GFCI cords.
What warranty do Westinghouse electric pressure washers have?
All six listings mention a 3-year limited warranty covering service, labor and parts.
