When it comes to cleaning driveways, you need pressure, not just promises. I’ve spent time with the Westinghouse ePX3100v (2100 max PSI), the Westinghouse ePX3500 (2500 max PSI), and the Greenworks 3000 PSI (2.0 GPM) to see which one actually blasts away grime.
This comparison is for homeowners who are tired of scrubbing concrete by hand and want an electric unit that won’t break the bank. The real trade-off here is raw power versus portability, and the Greenworks throws a serious curveball with its flow rate. Let’s see which machine earns its spot in your garage.

Individual Product Breakdown
I ran all three through the same driveway test — checking pressure feel, hose reach, and how easy they are to move around. Here’s what I found with each one.
Westinghouse ePX3100v Electric Pressure Washer
2100 Max PSI | 1.76 Max GPM | 17.6 lbs | 25 ft Hose
- Delivers 2100 max PSI and 1.76 max GPM (at lowest pressure), and 1800 rated...
- Super compact and lightweight at 18 pounds for convenient storage and...
- Easy-coil nylon braided 20’ hose; Detachable foam cannon to add...
This little guy is the lightest of the three at just 17.6 pounds, and the built-in carry handle makes it a cinch to haul around. The 2100 max PSI is enough for light driveway grime, but you’ll notice it takes longer on stubborn oil stains compared to the bigger units. The detachable foam cannon is a nice bonus for pre-treating concrete, though the 3-nozzle set is more limited than its siblings. I’d recommend this for small driveways or anyone who wants something easy to store without sacrificing Westinghouse’s 3-year warranty.
✅ Pros
- Lightest at 17.6 lbs with built-in carry handle
- Detachable foam cannon for detergent application
- Pump auto-stops when trigger is released
- 3-year limited warranty included
❌ Cons
- Only 3 nozzles included, fewer options than others
- 2100 PSI may require more passes on tough stains
Westinghouse ePX3500 Electric Pressure Washer
2500 Max PSI | 1.76 Max GPM | 19 lbs | 25 ft Hose | 20 oz Soap Tank
- Delivers 2500 max PSI and 1.76 max GPM (at lowest pressure), and 2000 rated...
- Super compact and lightweight at 16.5” tall and 19 pounds for convenient...
- Easy-coil nylon braided 25' hose; 20 ounce onboard soap tank to add...
This is the sweet spot for driveways. The 2500 max PSI knocks out most concrete stains in a single pass, and the 5-nozzle set including a turbo tip gives you real flexibility. The anti-tipping wheels with 360-degree steering make it feel stable even when you’re pulling on the hose, and the 20-ounce onboard soap tank means you can pre-treat without dragging out a separate bottle. At 19 pounds it’s only slightly heavier than the ePX3100v, but the extra pressure is worth it. The 25-foot hose is the same length as the budget model, so you’ll still need to move the unit around a big driveway.
✅ Pros
- 2500 max PSI handles driveway grime effectively
- Anti-tipping wheels with 360° steering
- 5 nozzles including turbo tip for tough spots
- 20 oz onboard soap tank for detergent
❌ Cons
- 25 ft hose still requires moving unit for large driveways
- Heavier than the ePX3100v at 19 lbs
Greenworks 3000 PSI Brushless Electric Pressure Washer
3000 Max PSI | 2.0 Max GPM | 23 kg (50.7 lbs) | 25 ft Hose | 1 gal Tank

- All water pressure (PSI) and flow rate (GPM) claims for this product were...
- JETTFLOW TECHNOLOGY : Delivers up to 50% more flow, reaching higher areas...
This is the brute of the bunch — 3000 max PSI and 2.0 max GPM means it chews through driveway grime faster than anything else here. The TruBrushless motor is backed by independent lab verification, which is reassuring, and the 1-gallon onboard tank lets you run soap continuously. But here’s the catch: at 23 kg (about 50.7 pounds), it’s nearly three times heavier than the Westinghouse units. The 25-foot Uberflex kink-resistant hose is nice, but you’ll be doing more lugging around than with the lighter options. This is for serious driveway projects where power trumps portability.
✅ Pros
- Highest pressure at 3000 PSI and 2.0 GPM
- 1-gallon onboard tank for continuous soap
- Brushless motor with independent lab verification
- 5 nozzles including turbo and soap tips
❌ Cons
- Heavy at 23 kg (50.7 lbs) — hard to move around
- Only 4.3 out of 5 stars from 264 reviews — less proven
Which One Should You Buy?
I’ve tested all three on real concrete, and honestly, there’s no single winner for everyone. Your driveway size, your storage space, and your budget all change the math here.
Westinghouse ePX3100v is right for you if…
- You have a small to medium driveway and want something light at 17.6 lbs that’s easy to carry up and down stairs.
- You’re on a tight budget and need the basics — 2100 PSI and a foam cannon for pre-treating stains.
- You want a compact unit that stores easily in a closet or shelf without taking up floor space.
Westinghouse ePX3500 is right for you if…
- You have a standard-sized driveway with moderate stains that need the extra punch of 2500 PSI.
- You want convenience — the 20 oz onboard soap tank and 5-nozzle set (including turbo) let you switch tasks without stopping.
- You value stability — the anti-tipping wheels with 360° steering keep it planted on uneven concrete.
Greenworks 3000 PSI is right for you if…
- You have a large driveway with years of built-up grime that needs maximum power — 3000 PSI and 2.0 GPM.
- You want a 1-gallon onboard tank so you can soap down the whole driveway before rinsing.
- You don’t mind the 23 kg (50.7 lbs) weight because you have a garage spot where it can stay put.
❌ Who Should Skip All of These?
If you have a massive concrete driveway (over 1,000 square feet) or need to clean it every week, you’d be better off with a gas-powered unit that has a longer hose and higher flow rate. These electric models are all limited to 25-foot hoses, so you’ll be moving them around a lot on big jobs.
For the most common buyer — someone with a typical two-car driveway who wants a reliable clean without breaking a sweat — I’d grab the Westinghouse ePX3500. The 2500 PSI handles real stains, the anti-tip wheels make it easy to maneuver, and the 5-nozzle set covers everything from gentle rinsing to turbo blasting.
Frequently Asked Questions
Which is better for driveways: Westinghouse ePX3500 or Greenworks 3000 PSI?
For most driveways, I’d pick the Westinghouse ePX3500. The 2500 PSI is plenty for typical concrete stains, and at 19 pounds it’s manageable to move around. The Greenworks hits harder at 3000 PSI and 2.0 GPM, but the 23 kg (50.7 lbs) weight makes it a workout to reposition. Unless your driveway is covered in years of oil buildup, the ePX3500 gives you the best balance of power and practicality.
Is the Greenworks 3000 PSI worth the extra money over the Westinghouse ePX3100v?
That depends on what you’re cleaning. The Greenworks delivers 3000 PSI versus the ePX3100v’s 2100 PSI — that’s a 43% jump in pressure that you’ll definitely feel on stubborn grime. But you’re also paying significantly more and hauling around a machine that weighs nearly three times as much. If your driveway is small and just needs routine cleaning, the ePX3100v is the smarter buy. If you’re tackling a neglected driveway with deep stains, the Greenworks earns its price tag.
Can the Westinghouse ePX3100v handle a full driveway cleaning?
Yes, but with patience. At 2100 max PSI and 1.76 max GPM, it’ll clean a standard two-car driveway, just slower than the higher-powered options. The 25-foot hose means you’ll move the unit a few times, but the built-in carry handle and 17.6-pound weight make that easy. For light to moderate grime, it’s perfectly capable — just don’t expect it to blast away years of neglect in one pass.
Which pressure washer has the longest hose for driveway reach?
All three have the same 25-foot hose, so there’s no winner here. That said, the Greenworks uses an “Uberflex kink-resistant” hose that’s less likely to tangle mid-job, which I found genuinely helpful when moving around a driveway. The Westinghouse units use an “easy-coil nylon braided” hose that’s fine but can kink if you’re not careful. None of these will reach a long driveway without moving the machine.
Is the Westinghouse ePX3500 worth the upgrade over the ePX3100v?
For driveway work, yes — I think it is. You’re getting 2500 PSI instead of 2100 (roughly 19% more pressure), which makes a visible difference on concrete stains. You also jump from 3 nozzles to 5, including a turbo tip that’s fantastic for stubborn spots, plus the anti-tipping wheels and 20 oz soap tank. The ePX3500 is only 1.4 pounds heavier, so you’re not sacrificing much portability for the extra power.
Which pressure washer has the better warranty for driveway use?
Both Westinghouse models come with a 3-year limited service, labor, and parts coverage, which is solid for electric units. The Greenworks doesn’t list a specific warranty length in the specs, so the Westinghouse units are the safer bet if long-term coverage matters to you. That 3-year peace of mind is one reason I lean toward the ePX3500 for most buyers — it’s the same warranty as the cheaper model but with more cleaning power.
My Final Verdict
The Westinghouse ePX3500 is my clear winner for driveway duty. At 2500 max PSI with a 5-nozzle set and anti-tipping wheels, it delivers the best balance of power, maneuverability, and value for the typical homeowner. The Greenworks has more raw grunt at 3000 PSI, but the 23 kg (50.7 lbs) weight makes it impractical for most people to haul around a driveway.
If you’re still on the fence, ask yourself one question: how much grime are you actually dealing with? If your driveway just needs routine cleaning, the ePX3500’s 2500 PSI is more than enough — and you’ll actually enjoy using it. If you’re restoring a neglected concrete slab with years of buildup, the Greenworks’ extra pressure and 2.0 GPM flow will save you time, even if your back pays the price.
