The Westinghouse ePX3100v is the better pick for a car wash with foam, and the Westinghouse ePX3100 is the better pick if you want wheels. Both are corded electric washers with 1.76 max GPM and a 3-year limited warranty, so the differences come down to foam, weight and pressure.
This Westinghouse ePX3100v vs ePX3100 comparison covers the specs, the foam setup, the wheels and the paint trade-offs. It also tells you which model to buy for which car owner.
Westinghouse ePX3100v vs ePX3100: the short answer
Pick the ePX3100v for foam and a lighter carry, and the ePX3100 for wheels and a soap tank on the washer.
The ePX3100v comes with a detachable foam cannon and weighs 17.6 pounds. The ePX3100 has four wheels and a 20 ounce onboard soap tank, and it weighs 19 pounds.
Neither one is the stronger washer on every count, so the choice depends on how you wash. If you're unsure, start with the foam question: do you want a cannon in the box, or wheels under the washer?
Westinghouse ePX3100v vs ePX3100 specs side by side
| Product | Best for | Max PSI | Flow | Weight | Our score |
|---|---|---|---|---|---|
| Westinghouse ePX3100v | a foam wash with a detachable cannon | 2100 | 1.76 GPM max | 17.6 lb | 8.6 |
| Westinghouse ePX3100 | an easy-to-roll car wash with wheels | 2300 | 1.76 GPM max | 19 lb | 8.7 |
Max PSI is the peak the washer can reach, and rated PSI is the level it's built to hold in everyday use. The rated numbers are 1800 PSI and 1.2 GPM for the ePX3100v, and 1900 PSI and 1.24 GPM for the ePX3100.
Both reach the same 1.76 GPM max, measured at the lowest pressure setting. That's why flow doesn't separate these two washers on a car.
What each washer is built for
The ePX3100v is a compact washer with a cannon, built for someone who wants one kit for cars, fences and patios. Westinghouse says it works for cars, fences, driveways, homes and patios.
The ePX3100 is a compact washer with wheels and a five-tip set, built for someone who moves the washer around the yard. Westinghouse says it works on decks, fences, driveways, cars and patio furniture.
Both suit a home car wash, so the real question is which build fits your space and your routine.
Max PSI and flow: 2100 against 2300
The ePX3100 has the higher max PSI, 2300 against 2100, but both reach 1.76 GPM max. That extra 200 PSI mostly helps on tougher surfaces like concrete, not on a car.
For paint, the lower top pressure of the ePX3100v leaves more room for error. Paint that is chipped, peeling or poorly repainted can lift under either washer, so check those spots first and keep the spray moving.

Foam cannon or soap tank: how each one adds soap
The ePX3100v adds foam with a detachable cannon, and the ePX3100 adds soap through a 20 ounce onboard tank. Those are two different routes to a soapy wash.
The cannon makes thicker foam, and it detaches so you can take it off for a plain rinse. The onboard tank on the ePX3100 holds 20 ounces, but it lets you apply soap through the wand without a separate cannon.
Use car wash soap as its label says, and never mix chemicals in the cannon or the tank.
ePX3100v cannon and ePX3100 soap tank in practice
For a foam-first wash, the cannon is the better tool. Rinse the car, foam it panel by panel, let the foam sit as the label says, then rinse again.
The ePX3100 suits a soap-and-rinse wash, which is a fine routine if you don't want thick foam. Its five nozzle tips include 0, 15 and 25 degree options, plus turbo and a soap applicator.
The ePX3100v comes with a three-nozzle set, so check the tip angles before you buy if you want a specific fan.
Wheels, weight and storage
The ePX3100 is easier to roll, and the ePX3100v is easier to carry. The ePX3100 has four quick-lock wheels with 360 degree steering, and Westinghouse says its low center of gravity and anti-tipping design help it stay upright.
The ePX3100v weighs 17.6 pounds, has a built-in carry handle and measures 15 by 8.5 by 11 inches. The ePX3100 weighs 19 pounds and measures 14 by 13.5 by 16.5 inches.
If your storage is a shelf or a corner of a garage, the ePX3100v's shorter height fits more places. If you roll the washer out of a shed each time, the wheels on the ePX3100 do more of the work.
ePX3100v and ePX3100 storage and moving
Measure the path from the door to the wash spot before you choose. The ePX3100's 16.5 inch height matters under a low shelf, and the ePX3100v's carry handle matters on stairs.
Hose, cord and reach around a car
The ePX3100 has a 25 foot easy-coil braided hose, which lets you work around a sedan without moving the washer every few feet. Westinghouse describes a 20 foot hose for the ePX3100v, while another spec line gives 25 feet, so confirm the length before you buy.
Plug either washer into a GFCI-protected outlet, and keep the cord off wet ground. Follow the maker's manual for every power connection.
Setup and the first wash on either model
Assemble the wand and hose, attach the nozzle you plan to use, and check each fitting for leaks before you plug in. Both washers follow the same basic order: connect water, rinse first, then add soap.
On the ePX3100v, fill the detachable cannon with car wash soap as its label says before you attach it. On the ePX3100, fill the onboard tank the same way, and use the soap applicator for the first pass.
Rinse the car from the top down, and keep the wand moving so the soap doesn't dry on the paint. Finish with a clean rinse, then dry the car with a soft towel.
Which washer gives more room for error on paint?
The ePX3100v's lower 2100 max PSI leaves more room for error than the ePX3100's 2300. That gap matters most when you wash older paint or work close to a panel edge.
On the ePX3100, the 25 degree tip is the widest fan in the set, so it's the safe first pick on paint. Keep the narrow 0 and 15 degree tips for tougher surfaces.
A spray at these pressures can hurt skin and eyes, so keep the wand pointed at the car and never at people or pets.
Sedan, SUV or truck: which reach fits
A sedan is easy to reach from one spot with either washer. A full-size truck or SUV needs more hose, and the ePX3100's 25 foot hose is the surer bet for a big vehicle.
Its smaller footprint of 15 by 8.5 inches suits a tight spot beside a truck, which is a point for the ePX3100v. Check how far the cord and hose reach before you set up, since that decides where you can park the washer.
Who should skip both washers
Skip both if you want 3000 max PSI or a long cord. Neither washer reaches 3000 max PSI, and neither one states a cord length.
Skip both if you want a 40 degree tip, too. The ePX3100 kit has 0, 15 and 25 degree tips plus turbo and soap, and the ePX3100v states only that it has three tips.
For a big truck or SUV, plan around the rated flow, not the 1.76 max GPM. Westinghouse rates the ePX3100v at 1.2 GPM and the ePX3100 at 1.24 GPM.
Which Westinghouse fits your car wash
Choose the ePX3100v if you want a detachable foam cannon in the box and a washer you can carry. It fits a driveway wash with foam and a small garage with a shelf or corner for storage.
Choose the ePX3100 if you want wheels, an onboard soap tank and a 25 foot hose. It fits a car owner who rolls the washer out of a shed and doesn't need thick foam.

Warranty and support on both washers
Westinghouse backs both washers with a 3-year limited service, labor and parts warranty. It also says its customer service and support network is nationwide.
A limited warranty sets the rules for any claim, so read the terms before you buy. Keep the receipt and the terms together, since a claim usually needs both.
Neither warranty is longer than the other, so it won't decide between these two.
Verdict: Westinghouse ePX3100v vs ePX3100
Buy the ePX3100v for a foam wash, and the ePX3100 for wheels.
Both carry a 3-year limited warranty and both reach 1.76 max GPM, so those aren't the deciding factors. If you wash with foam most weeks, the ePX3100v's cannon saves you a purchase.
If you roll the washer in and out of a garage or shed, the ePX3100's four wheels are worth the extra 1.4 pounds.
Before you order, check three things:
- The model name reads ePX3100v or ePX3100, not the ePX3100s.
- The hose length matches your reach around the car.
- Your paint has no chipped, peeling or poorly repainted spots you would spray.
