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

A compact, capable pressure washer that punches above its size

I spent a few weekends putting the ePX3500 through the kind of chores most homeowners face: refreshing a weathered deck, clearing mildew from siding, and lifting tire scuffs off a concrete driveway. What stood out immediately is how approachable this washer is. It’s compact, low to the ground, and sits on four swivel casters that actually work—roll it, tug it, park it on a slope with the wheel locks engaged, and it stays planted. That low center of gravity makes tipping a nonissue, even when you pull by the hose.

Under the tidy shell, you’re getting an electric unit rated at 2000 PSI and 1.2 GPM, with higher peak numbers at initial discharge. In practice, that means it has the punch you want for typical home maintenance without the hassle of gas: no carb to babysit, no fumes, quieter operation, and a motor that stops automatically when you release the trigger.

Setup and build

Assembly took me about 15 minutes. The steel wand is reassuringly solid, and the quick‑connect nozzles snap on with a positive click. The hose uses easy‑lock fittings that seal well once fully seated. Take the time to pull the collars all the way back before engaging; once you get the feel for it, swaps are quick and leak‑free.

At 16.5 inches tall and around 19 pounds, storage is simple. There are on‑board slots for the nozzles and wand, and while everything has a home, the accessory holders could be tighter—hit a bump and a nozzle can pop loose if it isn’t snapped in firmly. The 25‑foot nylon‑braided hose is durable and resists kinking, though it’s stiffer than a premium rubber hose; it coils better if you warm it in the sun first.

Power and cleaning performance

On power, the ePX3500 lands where a good electric should: enough authority to clean without constantly worrying you’ll scar a surface, but not the raw, gouge‑happy blast of a big gas unit. The nozzle set—0°, 15°, 25°, turbo, and soap—covers most jobs:

• 25° (green) became my default for decks and general cleanup.
• 15° (yellow) is excellent for concrete and pavers when you need more bite.
• 0° (red) is surgical; I reserve it for small, stubborn spots and avoid it on paint or softwood.
• Turbo is surprisingly aggressive—great on etched concrete or stone, but test first on finishes you care about.

On a 12×16 deck with a few seasons of grime, I worked a steady pass with the 25° tip, keeping the nozzle about six inches off the boards to avoid lap lines. It took me a little over an hour to get a uniform clean that was ready for stain. Keeping the wand moving and maintaining distance is key; the washer has the power to leave “zebra stripes” if you linger too close.

For vinyl siding, the 25° tip at a greater standoff removed mildew without chewing the surface. I pre‑treated with detergent from the onboard soap tank, let it dwell, then rinsed at low pressure before stepping up. The soap tank is 20 ounces, which is enough for spot applications and small zones. For full‑house washing or car‑detailing foam sessions, I prefer an external foam cannon; the ePX3500’s standard 1/4‑inch quick connects on the wand make accessory swaps easy.

On concrete, the 15° tip lifted tire scuffs and general grime with a few slow passes. Oil stains required detergent dwell time and, in a couple of spots, the turbo nozzle. A dedicated surface cleaner attachment will speed up large patios and reduce striping, but even without one, this unit can handle driveway refreshes with a bit of patience.

Mobility and ergonomics

The four‑wheel design is more than a gimmick. It glides behind you as you work and won’t topple when the hose snags. The wheel locks matter on sloped driveways or when you’re scrubbing in place. The low profile also makes it easy to store under a shelf.

The 17.5‑inch steel wand is sturdy and well‑balanced, though some users will want an extension for ground‑level work to reduce bending. Trigger pull is light, and the motor’s total stop system cuts noise between bursts and reduces wear. Vibration at the handle is minimal for an electric unit.

Noise-wise, it’s comfortably quieter than any gas washer I’ve used. You can have a normal conversation a few feet away, which is great for weekend projects in close neighborhoods.

Soap delivery and accessories

The built‑in soap tank is convenient for targeted cleaning—think algae streaks, patio furniture, or wheel wells. It’s not a high‑foaming system and isn’t intended to blanket a vehicle; pair the washer with a foam cannon if that’s a priority. After using detergents, flush the system with clean water to keep the pump and lines happy.

Because the wand and tips use standard quick‑connects, the ePX3500 plays well with third‑party accessories: longer lances, rotary brushes, 90° underbody adapters, and surface cleaners. That compatibility extends the tool’s usefulness well beyond the included kit.

Limitations and quirks

• Max vs. rated specs: Like most electrics, the headline PSI and GPM reflect initial or minimal‑restriction conditions. Real‑world cleaning power is defined by the rated 2000 PSI/1.2 GPM, which is still perfectly adequate for home maintenance.
• Hose stiffness: Durable, yes; supple, not really. It can tug the unit when coiled tight. Plan on an upgrade if you value a softer, more pliable hose.
• Accessory retention: The on‑board holsters work, but a firmer snap or deeper pockets would keep tips and the wand more secure during transport.
• Turbo nozzle care: It’s powerful enough to lift paint from weathered siding or wood if you get too close. Test on an inconspicuous area and build up cautiously.

None of these are deal‑breakers; they’re typical of the class and easy to work around with good technique and a few accessory tweaks.

Maintenance and durability

The automatic stop when you release the trigger is more than a convenience—it reduces heat and wear in the pump, which should extend life. I inspect O‑rings, keep the inlet filter clean, and never run the pump dry. If you store it in freezing climates, run pump saver or RV antifreeze through the system to prevent damage. The steel wand and brass quick‑connects have held up well so far, and the three‑year limited warranty is a welcome confidence booster in a category where one‑year coverage is common.

Tips for best results

• Start gentle: Begin with the 25° tip and increase pressure or decrease distance only as needed.
• Keep your distance: On wood, maintain a consistent six to eight inches to avoid streaks.
• Let chemistry help: Pre‑treat greasy or mildewed areas with detergent and dwell before blasting away.
• Work methodically: Overlap passes slightly to avoid zebra striping on decks and driveways.
• Protect the pump: Always connect water, purge air, and squeeze the trigger before powering on; flush detergent afterward.

Who it’s for

If you want a small, stable electric pressure washer that stores easily, rolls smoothly, and can handle the bread‑and‑butter chores of home ownership, the ePX3500 hits the mark. It’s ideal for decks, patios, fences, vehicles, outdoor furniture, and routine siding maintenance. If your workload is heavy commercial cleaning, thick oil‑soaked concrete, or you want the fastest possible stripping power, a higher‑flow gas model and a surface cleaner will be more efficient—at the cost of noise, maintenance, and storage footprint.

Recommendation

I recommend the ePX3500 for homeowners who value compact size, thoughtful mobility, and dependable, real‑world cleaning power. It’s easy to live with, has enough muscle for the jobs most of us actually do, and the four‑wheel, low‑center design makes it the most stable small washer I’ve used. Add in the steel wand, sensible nozzle set, total stop system, and a three‑year warranty, and it presents strong value. Expect to upgrade the hose if you want something more flexible and be mindful with the turbo tip, but those are minor trade‑offs for a pressure washer that’s this convenient, capable, and straightforward to use.
