Corded or cordless pressure washer: which should you buy?

One runs forever within 35 feet of a socket. The other goes anywhere for half an hour. The published numbers make this less of a toss-up than it looks.

Pressure washer cleaning a driveway

We have not tested these units. Every spec on this page comes from the manufacturer's own documentation and is linked to it. Every computed figure is arithmetic you can redo. Prices are checked daily — last verified January 1, 1970. Here is exactly how we pick.

Pressure washers are the one yard tool where the corded option is still genuinely competitive, and the reason is simple: a pump running continuously is a much easier engineering problem than a pump running off a battery. The published figures reflect that, and not in the direction most people expect.

The short answer

The cordless machine is the more powerful one. Greenworks publishes up to 3000 PSI and 2.0 GPM — 6,000 cleaning units — against the corded Sun Joe's 2030 PSI and 1.2 GPM, or 2,436. What corded buys is not output, it is duration: the Greenworks publishes 30 minutes and the Sun Joe publishes none, because it does not need one.

Comparing them properly: cleaning units

PSI on its own is a bad way to shop. Pressure lifts dirt off a surface; flow carries it away. Multiply them and you get cleaning units, which is the figure that actually tracks how fast a surface gets clean. We set out the full reasoning in the pressure washer buying guide.

The arithmetic — Cleaning units, both machines
Greenworks 60V, full output
3000 PSI x 2.0 GPM = 6,000 cleaning units
Greenworks 60V, published Eco mode
2200 PSI x 1.0 GPM = 2,200 cleaning units
Sun Joe SPX3000, corded
2030 PSI x 1.2 GPM = 2,436 cleaning units

The middle line is the interesting one. Greenworks' Eco mode lands within 10% of the corded machine's full output. In other words, the cordless washer detuned to save battery is about as capable as the corded washer flat out — and that is the mode most routine work needs.

From the Greenworks 60V and Sun Joe SPX3000 product pages, checked 3 September 2026. Cleaning-unit figures are our arithmetic. Sun Joe lists this model at both 13 A and 14.5 A across variants — confirm the amperage on the exact SKU before buying.

The Sun Joe column has more rows filled in, and that is not an accident of our research. The corded machine's page publishes nozzles, tanks, hose, cord and a safety system; the cordless page publishes pressure, flow, mode and runtime. Two brands with two different ideas of what a buyer needs to know.

The specification that usually decides it

Neither pressure nor runtime is the constraint for most households. Reach is.

The arithmetic — Working radius, corded
Published cord: 35 ft
Published hose: 20 ft
Straight-line reach from the socket: about 55 ft
Then subtract every corner the cord has to go round

Measure that against your actual job before you compare a single PSI figure. If the far end of the driveway, the fence line or the boat on the drive sits outside 55 feet of a socket, the corded machine is not a cheaper version of the cordless one — it is a machine that cannot do the job.

What 30 minutes actually covers

Thirty minutes sounds short next to unlimited, and in trigger time it is less restrictive than it sounds: pressure washing is intermittent work with long pauses for repositioning, soaping and scrubbing. What it does rule out is a continuous session — a whole driveway in one go, or a long fence run.

Two mitigations are published. Eco mode at 2200 PSI and 1.0 GPM halves the flow, and Greenworks notes dual-battery kits are available. If you buy this machine for a big job, buy it that way.

Which one, by situation

  • Driveway, patio and car within 55 feet of a socket: corded. Unlimited runtime, five nozzles and two detergent tanks published, and nothing to charge.
  • Anything at the far end of a property: cordless. This is the entire reason the category exists.
  • You already own Greenworks 60V tools: cordless. The pack is already in the shed and the washer ships tool-only.
  • You want the highest output available: cordless, on these two. 6,000 cleaning units against 2,436 is not close.
  • Long continuous sessions: corded. Thirty minutes is thirty minutes, however you split it.

What we cannot tell you

We have not run either washer. Pump durability, how close real output sits to the rated maximum, how long a trigger-time half hour lasts in practice, and how either machine copes with a poor water supply are all beyond what these pages publish.

Greenworks also sells several 60V washers at different pressures — check that the SKU in front of you matches the PSI you think you are buying. And on the corded side, confirm the amperage on the exact model, since Sun Joe lists this one two ways.

3000 PSI and 2.0 GPM with no cord, and a published Eco mode that trades pressure for the runtime you actually need.

What the numbers favor

  • Highest published pressure of the two washers here, by nearly 1000 PSI
  • No cord -- works anywhere on the property
  • Eco mode is published with real numbers (2200 PSI / 1.0 GPM), not just a label
  • Shares the Greenworks 60V pack with the rest of that platform

What they don't

  • 30 minutes of published runtime against a corded washer's unlimited
  • Greenworks publishes several 60V washers at different pressures; check the SKU matches the PSI you are paying for
Skip this one if

you wash a driveway twice a year within reach of an outlet. You would be buying 60V packs to solve a problem an extension cord already solves.

your working area is beyond easy reach of an outdoor outlet. A cordless washer trades runtime for the ability to walk away from the house.

Common questions

Is a cordless pressure washer worth it?
If your work is away from an outlet, yes. The Greenworks 60V publishes up to 3000 PSI and 2.0 GPM -- 6,000 cleaning units -- against 30 minutes of runtime. The Sun Joe SPX3000 publishes 2030 PSI and 1.2 GPM, which is 2,436 cleaning units, and it runs as long as you leave it plugged in.
What are cleaning units?
PSI multiplied by GPM. It combines the pressure that lifts dirt with the water volume that carries it away, and it is the honest single number for comparing washers. The Greenworks at full output is 6,000; the Sun Joe is 2,436; a garden hose is about 250.
How long does a cordless pressure washer run?
The Greenworks 60V publishes up to 30 minutes. Its Eco mode drops output to a published 2200 PSI and 1.0 GPM, which is 2,200 cleaning units -- close to the corded Sun Joe's 2,436 -- and is the setting most driveway work actually needs.
Is corded more powerful than cordless?
Not in this pairing. The cordless Greenworks publishes nearly 1000 PSI more and 0.8 GPM more than the corded Sun Joe. The corded machine's advantage is duration, not output.
What is the real working radius of a corded washer?
The Sun Joe publishes a 35 ft cord and a 20 ft hose, so about 55 feet from the socket in a straight line before you add an extension. That is the number to measure against your driveway, not the pressure figure.
Which is better for a driveway?
Whichever reaches it. If your driveway sits inside 55 feet of an outdoor socket, corded gives you unlimited runtime for the whole job. If it does not, 30 minutes of cordless beats an extension cord you have to keep moving.
