Verdict up front: if you have an outdoor outlet and don’t mind a cord, the Sun Joe SPX3000 is the strongest all-around electric pressure washer here for the money, with the highest PSI of the three corded options. If your driveway or deck is nowhere near an outlet, the Ryobi 40V HP RY40PW15 is the only one of the three that doesn’t need one — but you’re paying roughly triple the price for that freedom. The Greenworks GPW2000 splits the difference: corded, compact, and priced below the Sun Joe if that combination matters more to you than raw PSI.
At a glance
Best overall: Sun Joe SPX3000 — 2,030 PSI, unlimited runtime on a cord, and a 2-year warranty for around $169.
Best budget: Greenworks GPW2000 — 2,000 PSI in a lighter, more compact corded design.
Best cordless: Ryobi 40V HP RY40PW15 — no cord, no hose reel to fight, but a hard 20–45 minute runtime cap and a $599 price tag with batteries included.
Every pressure washer comparison eventually comes down to one question people don’t ask until it’s too late: corded or cordless? PSI numbers get all the marketing attention, but for most driveways, decks, and cars, the real decision is whether you’re willing to run an extension cord or willing to pay several hundred dollars extra for the freedom to walk away from an outlet. We lined up the Sun Joe SPX3000, Greenworks GPW2000, and Ryobi 40V HP RY40PW15 to make that trade-off concrete.

Meet the Three Washers
Sun Joe SPX3000
The SPX3000 is one of the best-known names in home pressure washing for a reason: a 13-amp motor pushing up to 2,030 PSI of certified-rated water pressure, currently listed at $169 on Sun Joe’s own site, backed by a 2-year warranty and a 30-day money-back guarantee. Because it’s corded, runtime is unlimited as long as you’re near an outlet — the tradeoff is managing a power cord alongside the hose while you work.
Greenworks GPW2000
Greenworks’ 2,000 PSI, 1.1 GPM corded electric washer lists around $210 at major retailers and trades a small amount of peak PSI for a lighter, more compact body — a real consideration if you’re hauling it up and down stairs to a garage or shed between uses. Like the Sun Joe, it’s corded, so runtime isn’t a factor, only outlet access is.
Ryobi 40V HP RY40PW15
This is the only cordless option of the three, running on two included 40V 6.0Ah batteries with a brushless “Whisper Series” motor rated at 57 dB — noticeably quieter than a typical corded unit. It delivers up to 1,500 PSI in boost mode (1,000 PSI in default mode) and 1.2 GPM, with a runtime of roughly 20 minutes on high power up to about 45 minutes on low, per battery charge. It can self-prime from a bucket as well as a garden hose. At $599 with batteries and charger included, and backed by a 5-year tool warranty and 3-year battery warranty, it’s priced closer to a serious cordless power-tool investment than an impulse buy.
Original Data: Runtime, Coverage, and What Cordless Freedom Actually Costs
PSI comparisons are everywhere; a straight read on what you actually get for the cordless premium is not. Here’s a straight comparison of realistic coverage per charge on the Ryobi, and what that cordless convenience actually costs against the two corded options.
| Sun Joe SPX3000 | Greenworks GPW2000 | Ryobi 40V HP RY40PW15 | |
|---|---|---|---|
| Effective runtime per session | Unlimited (cord length + extension cords only) | Unlimited (cord length + extension cords only) | 20–45 min, then a battery swap or recharge (2–3 hr typical recharge time for 6.0Ah packs) |
| Realistic single-charge coverage | N/A — not runtime-limited | N/A — not runtime-limited | Roughly a two-car driveway or a mid-size deck on one charge in high mode; more on low mode |
| Upfront cost | $169 | ~$210 | $599 (includes 2 batteries + charger) |
| Cost of one spare battery, if needed later | N/A | N/A | Typically $150–$200 per 6.0Ah battery at retail |
| “Cordless premium” vs. Sun Joe | — | — | ~$430 more upfront for no cord and a runtime cap |
The takeaway is straightforward: if your cleaning jobs live within reach of an outdoor outlet and a couple of extension cords, both corded washers do the job for a few hundred dollars less and never run out of charge mid-job. The Ryobi earns its price only if you’re regularly cleaning somewhere a cord genuinely can’t reach — a detached shed, a far corner of a large property, or a boat or RV parked away from power.
Who Should Buy Which
- Most homeowners with an outdoor outlet: Sun Joe SPX3000 — the highest PSI of the three at the lowest price, with no runtime limit to plan around.
- Tight storage space or frequent moves between garage and job site: Greenworks GPW2000 — a lighter, more compact corded option if raw PSI matters less than portability.
- Detached structures, large properties, or boats/RVs away from outlets: Ryobi 40V HP RY40PW15 — the only one that goes where a cord can’t, at a real price premium.
- Anyone already invested in Ryobi’s 40V battery platform: the RY40PW15 becomes a much better value if you already own compatible 40V batteries from other Ryobi tools, since the effective cost drops close to a bare-tool price.
Dealbreakers to Know Before You Buy
None of these three washers are hot-water units — all three are cold-water only, which is standard for consumer-grade machines but won’t cut through grease the way a commercial hot-water unit would. The Ryobi’s 1,500 PSI peak is meaningfully lower than either corded option’s roughly 2,000 PSI, so tougher jobs like heavily stained concrete may take longer or need more passes. The Sun Joe and Greenworks both require an outdoor GFCI outlet and a cord rated for outdoor use — running either off an underrated indoor extension cord is a real safety issue, not just a performance one. Regardless of which you buy, always follow the manufacturer’s guidance on safe distance from surfaces, and never point any pressure washer at people, pets, or livestock.

Frequently Asked Questions
Is a corded or cordless pressure washer better for a driveway?
For most driveways within reach of an outdoor outlet, a corded washer like the Sun Joe SPX3000 or Greenworks GPW2000 is the better value — you get more PSI for less money and never have to think about runtime. Cordless models like the Ryobi RY40PW15 are worth the premium mainly when outlet access is the real obstacle.
How long does the Ryobi 40V pressure washer run on a charge?
Ryobi rates the RY40PW15 at roughly 20 minutes of runtime on high (boost) mode and up to about 45 minutes on low mode, using the two included 40V 6.0Ah batteries.
Do these pressure washers work with hot water?
No. The Sun Joe SPX3000, Greenworks GPW2000, and Ryobi RY40PW15 are all cold-water-rated consumer machines. None of them are designed for a hot-water supply.
Which of these three has the highest water pressure?
The Sun Joe SPX3000 has the highest rated pressure at up to 2,030 PSI, followed by the Greenworks GPW2000 at 2,000 PSI. The cordless Ryobi RY40PW15 tops out lower, at 1,500 PSI in boost mode.
