Sun Joe Pressure Washer, Electric Power Washer, 2500 Max PSI,
The established Sun Joe model, rated 2500 max PSI, is positioned as a general-purpose portable electric washer for the widest range of home surfaces listed.
Outdoor Cleaning
Ten pressure washers, electric and gas, compared on power, flow rate, and what's actually in the box.


The established Sun Joe model, rated 2500 max PSI, is positioned as a general-purpose portable electric washer for the widest range of home surfaces listed.

The only electric unit here with a brushless motor and the highest electric PSI/GPM combination listed, at 3000 PSI and up to 2.0 GPM.

Explicitly marketed to homeowners, with a named AAA axial cam pump and a full accessory set at 3300 PSI / 2.4 GPM.

The only model built around a Honda GX200 engine, an AAA triplex pump, and a steel frame, and the only one marketed for professional use.

The lowest PSI and GPM rating on this list, sized for light-duty cleaning rather than large surfaces.

Scores 4.5 while sitting at the value pick end — the most this lineup gives back for what it asks.
“Legit” is our own 1–5 value score, computed the same way for every product from what its live listing showed — how we calculate it. A dash means one of the four inputs could not be read, so we do not score it. Everything else is qualitative. No prices — they move too fast for an article to stay true.

Established electric pressure washer
This is the long-running Sun Joe electric model, rated at 2500 max PSI (2030 PSI PWMA rated) and built as a portable unit for patios and sidewalks. It suits anyone who wants a plug-in washer without a garage full of gas-engine maintenance. The listing doesn't state a GPM figure, so pair the PSI rating against the jobs you actually have — driveways and heavy oil stains will take longer than a gas unit would. Best treated as a general-purpose outdoor cleaner rather than a heavy-duty tool.

Mid-range electric cold-water washer
RYOBI's electric model is rated 2500 PSI at 1.2 GPM, described as high-performance cold water — a straightforward corded option without the extras some competitors bundle in. The GPM figure is on the lower side for this PSI range, which means slower rinse-off on large flat surfaces, but it should be plenty for smaller cleaning jobs around a home. Worth considering if brand familiarity or a simpler feature set matters more than accessory count.

Highest-rated electric washer, brushless motor
This Greenworks model carries the highest specs among the electric options here — 3000 PSI and up to 2.0 GPM — and uses a brushless motor, which typically means less internal wear over time than a brushed equivalent. The higher flow rate should move more water per minute than the other electric units listed, useful on wider surfaces like driveways. The trade-off for the extra power is that it's still corded, so reach and outlet access matter more than with a gas unit.

Gas washer built for homeowner use
Simpson's Clean Machine is rated 3200 PSI at 2.5 GPM, with an axial cam pump, built-in soap tank, turbo nozzle, and a 25-foot hose — a fuller accessory set than some gas competitors at this tier. It's explicitly positioned for homeowners rather than pros, and the turbo nozzle should speed up stubborn spots like concrete stains. The 49-state compliance note matters only if California emissions rules apply to you; otherwise it's a straightforward mid-power gas unit.

High-flow gas washer with wide nozzle set
The Westinghouse WPX3400 sits at the top of the PSI range here — 3400 PSI and 2.6 GPM — with an onboard soap tank and a five-nozzle set covering everything from cars to fences to furniture per the listing. That breadth of listed use cases suggests it's built as an all-rounder rather than a single-purpose driveway tool. As with any gas unit, expect more upkeep than an electric washer, but the higher GPM should clear larger areas faster.

Homeowner-grade gas washer, name-brand pump
DeWalt's residential model runs 3300 PSI at 2.4 GPM and specifically calls out an AAA axial cam pump — a detail buyers who've worn out a cheaper pump will appreciate. It ships with a 25-foot hose, five nozzles, and an ergonomic spray gun, and is marketed directly at homeowners rather than commercial users. It's a strong middle-ground pick between the lighter gas units and the Honda-engine model on this list, without the added weight of a professional-grade pump.

Compact electric washer with long cord
The Sun Joe XTREAM is rated at 2,200 PSI with a 14.9-amp motor, four quick-connect nozzles, and a notably long 35-foot power cord plus garden hose adapter. The longer cord is the standout detail here — it extends reach without a separate extension cord, useful for larger yards. PSI is lower than the other Sun Joe on this list, so it's positioned as the lighter-duty option between the two.

Gas washer, cold water, mid-power tier
This RYOBI gas model matches the DeWalt and Simpson Clean Machine on core numbers — 3300 PSI at 2.5 GPM — as a cold-water unit without the extra accessory callouts some competitors list. It's a straightforward choice for buyers already invested in the RYOBI ecosystem or comparing purely on PSI/GPM parity with other mid-tier gas washers. The listing doesn't detail pump type or hose length, so compare those specifics directly against alternatives before deciding.

Professional-grade gas washer, Honda engine
The Simpson PowerShot is the only unit here built around a Honda GX200 engine and an AAA triplex pump — components typically associated with longer service life under frequent use — on a steel frame. It's marketed for professionals, not casual homeowners, which shows in the 3300 PSI / 2.5 GPM rating paired with a 25-foot MorFlex hose and five quick-connect nozzles. It's the heaviest-duty option on this list, and likely more machine than an occasional-use household needs.

Entry-level electric washer
Greenworks' smaller model is rated 2000 PSI at 1.2 GPM, the lowest specs on this list. That makes it suited to light jobs — outdoor furniture, small vehicles, bikes — rather than driveways or siding. Its size and lower power draw should also make it the easiest of the ten to store and move around, which matters for anyone without garage space for a larger unit. Not the pick if the job list includes anything beyond light residential cleaning.
Electric washers here top out around 3000 PSI and suit cars, patios, and furniture without engine maintenance or fuel storage. Gas models run higher flow rates (2.4–2.6 GPM) and are better suited to large driveways, siding, or heavily soiled concrete, at the cost of more upkeep and weight.
Not on its own. PSI measures pressure, but GPM (gallons per minute) measures how much water moves through the nozzle. A washer with lower PSI but higher GPM can clear a large surface faster than one with more pressure and less flow, so check both figures together.
Yes — the Simpson Clean Machine and the Westinghouse WPX3400 both list an onboard or built-in soap tank per their titles. Other listings here don't mention one, so check the specific product page if that's a requirement.
If you're cleaning a large yard or a two-story exterior, yes — the Sun Joe XTREAM's 35-foot power cord and several gas models' 25-foot hoses reduce how often you reposition the unit or need an extension cord.
It means the engine meets emissions standards everywhere except California, which has its own separate requirements. It only matters if you live in California; elsewhere it has no bearing on performance.
For most homes, an electric washer covers the actual chores — cars, patios, outdoor furniture — without the upkeep of an engine. The two Sun Joe units and the brushless Greenworks are the electric picks worth comparing on rated PSI and motor spec. If the job list includes long driveways, siding, or fencing, a gas unit's higher GPM does the work faster; the Honda-engine Simpson and the DeWalt stand out there for pump construction and stated hose/nozzle counts. Choose based on the surface area you actually clean, not the PSI number alone — a washer with lower pressure but higher flow can still finish a driveway quicker than one with more PSI and less GPM.
