Overview
Choosing among the best electric pressure washers is harder than it looks, because every box leads with a big PSI number. Those figures are manufacturer maximum ratings, and real cleaning depends on flow, nozzle choice and how the machine is built. This comparison looks at five plug-in models for washing cars, patios and fences. We weigh three things: the stated pressure and flow, the nozzles and soap options that come with the unit, and how easy it is to carry, store and set up at home. Treat the numbers as a starting point and match the machine to the jobs you actually do.

Based on published specs rather than testing, the ePX3500 offers the most complete kit here: five nozzles, an onboard soap tank, a 25 foot hose and anti-tipping design. Its 2500 PSI is a peak rating.
Check Price on Amazon →Sun Joe SPX3000 Electric Pressure Washer, 2500 Max PSI
The SPX3000 is a corded electric pressure washer aimed at general home cleaning such as cars, patios, fences and siding. Published specifications for this model describe a 14.5 amp, 1800 watt motor, 1.76 GPM flow, a 20 foot high pressure hose, a 35 foot power cord with a GFCI, and five quick connect nozzles (0, 15, 25, 40 degrees and soap). The maximum pressure is often quoted as 2030 PSI, with a lower typical working pressure of about 1450 PSI, while the Amazon title shows 2500 Max PSI, so confirm the exact figure on the listing. Buyers often mention that it feels like a step up from small units for decks and driveways. The trade-offs are weight, which listings put at roughly 24 to 31 pounds, and a bulkier body than the hand-carry models here.
Westinghouse ePX3100v Electric Pressure Washer, 2100 Max PSI
The ePX3100v is a compact electric pressure washer from Westinghouse built around easy handling. It is listed at 2100 max PSI and 1.76 max GPM, and the owner's manual gives a lower rated maximum of 1800 PSI, which is a useful reminder that peak numbers are not sustained pressure. It runs on 120 volts with a 13 amp motor and weighs about 18 pounds. The package includes a carry handle, a detachable foam cannon, a pro-style steel wand, a flexible 20 foot hose and a set of three quick connect nozzles. It suits car washing, patio furniture and light fence work for people who move the machine around a lot. The trade-offs are fewer nozzles than the ePX3500 and no onboard soap tank, so you rely on the foam cannon for detergent.
Westinghouse ePX3500 Electric Pressure Washer, 2500 Max PSI
The ePX3500 sits at the higher end of this group on paper, with a listed 2500 max PSI at initial discharge and up to 1.76 GPM. It uses a 120 volt, 13 amp motor, weighs about 19 pounds and includes anti-tipping design, an onboard detergent tank, a pro-style steel wand, a flexible 25 foot hose and five quick connect nozzles. The onboard soap tank and extra nozzles make it flexible for cars, fences, driveways and patios without buying add-ons. Because the 2500 figure is a peak rating from manufacturer testing, expect real working pressure to be lower, and note that its flow is the same 1.76 GPM as the ePX3100v. The trade-offs are a heavier body and a handling feel closer to a small cart-less unit than a grab-and-go washer.
Greenworks 1500 PSI 1.2 GPM Pressure Washer, Upright Hand-Carry
This Greenworks model is a lighter-duty electric pressure washer rated at 1500 PSI and 1.2 GPM with a 13 amp motor. It is PWMA certified and sold as an upright, hand-carry design that can be used vertically or horizontally for stability. Its modest output points to light to medium residential jobs such as washing cars, outdoor furniture, grills, bikes and small patios. It is the lowest-rated machine in this comparison for both pressure and flow, so cleaning large driveways or old stains will take longer and may stay out of reach. Listings disagree on details such as weight and hose length, so check the product page before buying. The appeal is simplicity and easy storage for people who wash occasionally and want something compact.
1800 PSI Electric Pressure Washer
This listing is titled simply 1800 PSI Electric Pressure Washer, and the title shows no brand. We could not verify the manufacturer, motor, flow rate, hose length, nozzle count or weight from independent sources, so we are not stating them here. What the title tells you is that it is an electric model advertised at 1800 PSI, which is a manufacturer maximum rating and sits between the Greenworks 1500 PSI unit and the 2100 to 2500 PSI Westinghouse and Sun Joe models. Pressure alone does not describe cleaning ability, since flow in gallons per minute matters just as much. Before buying, open the listing and confirm the GPM, accessories, cord length, warranty and who supports the product. It may suit a shopper wanting a mid-range electric washer, but the missing details make it the hardest to compare.
Conclusion
Choose the Sun Joe SPX3000 over the others if you want a well-documented 1.76 GPM machine with five nozzles and a long power cord for mixed jobs. Pick a Westinghouse model instead if you want a lighter body, or the Greenworks for easier storage. Read More →
Choose the ePX3100v over the ePX3500 if carrying and storing the machine matters more than extra nozzles and a built-in soap tank. It is a better fit for car washing with the foam cannon, but a poorer one for larger surfaces. Read More →
Choose the ePX3500 over the ePX3100v if you want an onboard soap tank, five nozzles and a longer hose for cars, fences and patios in one kit. It costs you a little extra weight, and its peak rating should not be read as sustained pressure. Read More →
Choose the Greenworks 1500 PSI unit over the stronger models if your jobs are small and you value compact, hand-carry storage. Skip it for big driveways or stubborn grime, where its lower pressure and 1.2 GPM flow will slow you down. Read More →
Choose the 1800 PSI washer over the named models only after confirming its flow, accessories and warranty on the listing. Because we could not verify its brand or specs, the Sun Joe or Westinghouse units are the safer, better documented options. Read More →
Frequently Asked Questions
Is a higher PSI always better for cleaning cars and patios? +
No. PSI is only part of the picture. Cleaning power also depends on flow in GPM, nozzle angle and distance from the surface. For cars, lower pressure with a wide nozzle and soap is usually enough, and higher pressure can damage paint or soft wood.
Are the listed PSI numbers what the washer really delivers? +
Usually not. Listed figures are manufacturer maximum ratings, often measured at initial discharge. The Westinghouse manual lists a lower rated maximum than its headline figure, and Sun Joe lists a working pressure below its peak. Expect real pressure to be lower.
What does GPM mean and why does it matter? +
GPM is gallons per minute of water flow. Flow carries dirt away, so a washer with higher GPM at similar pressure generally cleans faster. Among these models, the Sun Joe and both Westinghouse units list 1.76 GPM while the Greenworks lists 1.2 GPM.
Can I use hot water or any outlet with an electric pressure washer? +
Check the manual first. The Westinghouse manual says to use cold water only and describes 120 volt household power with a GFCI. Use a properly rated outlet, and avoid thin extension cords unless the manufacturer says they are allowed.
Should I buy a pressure washer listing that shows no brand? +
Be cautious. Without a named maker you cannot easily check specifications, parts or warranty support. If you consider the 1800 PSI listing, confirm GPM, nozzles, cord length and return terms on the listing before buying.
