Individual Product Breakdown
I spent time digging through the specs, customer feedback, and real-world usability of both washers. Here’s my honest take on each one, starting with the lighter option and moving to the more powerful pick.
Westinghouse ePX3100v Electric Pressure Washer
2100 Max PSI | 1.76 Max GPM | 17.6 lbs | 25 ft Hose | 3 Nozzles

I really like how this one handles — at just 17.6 pounds with a built-in carry handle, it’s the easiest to tote around tight spaces or up stairs. The detachable foam cannon is a nice touch for applying soap on cars or patio furniture without extra attachments. It delivers 2100 max PSI and 1.76 max GPM, which is plenty for most home jobs, but the 3-nozzle set feels a bit limited compared to the ePX3500. The easy-coil 20-foot hose is workable, though I wish it were a touch longer for bigger driveways.
✅ Pros
- Ultra-portable at 17.6 pounds with built-in carry handle
- Detachable foam cannon for easy soap application
- 2100 max PSI handles most home cleaning tasks
- Auto-stop pump saves energy when trigger is released
❌ Cons
- Only 3 nozzles included, fewer options than the ePX3500
- 20-foot hose is shorter than the 25-foot on the bigger model
- No onboard soap tank — you’ll need the foam cannon
Westinghouse ePX3500 Electric Pressure Washer
2500 Max PSI | 1.76 Max GPM | 19 lbs | 25 ft Hose | 5 Nozzles | 20 oz Soap Tank
- Delivers 2500 max PSI and 1.76 max GPM (at lowest pressure), and 2000 rated...

- Easy-coil nylon braided 25' hose; 20 ounce onboard soap tank to add...
This is the one I’d grab for tougher jobs like concrete driveways or heavily soiled fences. The 2500 max PSI is a clear step up from the ePX3100v’s 2100, and the 2000 rated PSI means it holds its own under continuous use. I love the 20-ounce onboard soap tank — no more fiddling with a separate foam cannon, just flip a switch and you’re sudsing. The anti-tipping wheels and low center of gravity make it stable on uneven ground, and the 5-nozzle set (0°, 15°, 25°, turbo, soap) covers everything. It’s 19 pounds, so slightly heavier, but the wheels make up for it.
✅ Pros
- 2500 max PSI and 2000 rated PSI for serious cleaning power
- 20-ounce onboard soap tank built right in
- 5-nozzle set including turbo for tough stains
- Anti-tipping wheels with 360° steering for easy maneuvering
❌ Cons
- Slightly heavier at 19 pounds, though wheels help
- Bulky footprint at 13.5″L x 14″W x 16.5″H takes more storage space
- Less portable — you won’t want to carry it up stairs
Which One Should You Buy?
Honestly, there’s no single “right” answer here — it comes down to whether you value portability or raw power more. Let me break down exactly who each washer fits best so you can match it to your own cleaning routine.
Westinghouse ePX3100v is right for you if…
- You need to carry your washer up stairs or into tight spaces — at just 17.6 pounds with a built-in handle, it’s the easy choice
- You want a quick soap-and-rinse setup for cars or patio furniture using the detachable foam cannon
- You have smaller cleaning jobs where 2100 max PSI is plenty and you’d rather save storage space
Westinghouse ePX3500 is right for you if…
- You tackle concrete driveways or heavily stained fences where the extra 400 PSI (2500 max) makes a real difference
- You hate swapping attachments — the 20-ounce onboard soap tank and 5-nozzle set (including turbo) keep everything handy
- You work on flat ground and want the anti-tipping wheels with 360° steering to glide around your yard
❌ Who Should Skip All of These?
If you need to clean large commercial surfaces or want to run for hours without stopping, you’re better off with a gas-powered washer — these electric models are designed for moderate home use, not marathon sessions. Also, if you have zero storage space and only wash one car a month, a simple garden hose attachment might be all you really need.
For most homeowners, I’d point you toward the Westinghouse ePX3500 — the 2500 max PSI, onboard soap tank, and 5-nozzle set give you the most flexibility for the widest range of jobs, and the wheels make the extra weight a non-issue. But if you live in a multi-story home or need something you can tote around easily, the ePX3100v’s 17.6-pound frame is a smart, budget-friendly pick.
Frequently Asked Questions
Which is better for cleaning a concrete driveway: the ePX3100v or ePX3500?
The ePX3500 is the clear winner here. With 2500 max PSI and 2000 rated PSI, it pushes about 19% more pressure than the ePX3100v’s 2100 max PSI and 1800 rated PSI — that extra punch really matters when you’re blasting years of grime off concrete. The turbo nozzle in the ePX3500’s 5-nozzle set also helps break up stubborn stains faster. If your driveway is your main priority, don’t settle for the smaller model.
Is the ePX3500 worth the extra money over the ePX3100v?
For most people, yes — but it depends on your jobs. The ePX3500 adds 400 max PSI, a 20-ounce onboard soap tank, a 5-nozzle set (including turbo), and anti-tipping wheels with 360° steering. That’s a lot of practical upgrades for the price difference. However, if you only wash a car or two and a small patio, the ePX3100v’s 2100 max PSI and foam cannon will handle it fine — and you’ll save some cash and storage space.
Which one is easier to move around and store?
The ePX3100v wins on portability, no question. It weighs just 17.6 pounds with a built-in carry handle, so you can haul it up stairs or into a closet with one hand. The ePX3500 is 19 pounds and has a bulkier footprint at 13.5″L x 14″W x 16.5″H — but its wheels make rolling it around a flat yard easier. If you’re storing it on a shelf or in a tight garage, go with the ePX3100v.
Do both washers have the same flow rate?
Yes, both deliver a maximum flow rate of 1.76 GPM and a rated flow of 1.2 GPM. That means the rinsing power is identical — the real difference is pressure, not water volume. So if you’re comparing cleaning speed, the ePX3500’s higher PSI is what gives it the edge on tough grime. The flow rate being the same also means both will use water at roughly the same rate.
Which model has better nozzles for different cleaning tasks?
The ePX3500 is much more versatile with its 5-nozzle set: 0°, 15°, 25°, turbo, and a soap applicator. The ePX3100v only comes with 3 nozzles, which limits your options for fine-tuning pressure on delicate surfaces like car paint. The turbo nozzle on the ePX3500 is a standout — it’s perfect for blasting off mildew or old paint without switching tips. If you like having the right tool for every job, the ePX3500 is the better buy.
Are both covered by the same warranty?
Yes, both the ePX3100v and ePX3500 come with a 3-year limited warranty covering service, labor, and parts, plus a nationwide customer support network. That’s solid peace of mind for either purchase. The main difference is that the ePX3500’s higher customer review count (13,214 ratings) suggests it’s been battle-tested by more owners, but the warranty protection is identical.
My Final Verdict
The Westinghouse ePX3500 is my clear overall winner for home use. That extra 400 PSI (2500 max vs 2100 max) makes a tangible difference on driveways and fences, and the 20-ounce onboard soap tank plus 5-nozzle set with turbo tip means you’ll rarely need another attachment. The anti-tipping wheels and 19-pound weight are a fair trade for the portability you lose from the ePX3100v.
If you’re still on the fence, think about your most common cleaning task. If it’s tough outdoor surfaces like concrete or siding, the ePX3500’s 2000 rated PSI will save you time every single use. If you mostly wash cars and need something you can carry upstairs, the ePX3100v’s 17.6-pound frame with built-in handle is the smarter, lighter pick — just know you’re giving up that turbo nozzle and soap tank.
