Corded vs Cordless Pressure Washer: Power, Runtime and Cost
Quick answer: Consumer Reports says corded models give consistent power and cost less, while battery models are convenient and quiet but can be much more expensive. Choose corded if an outlet is near, and cordless if you clean away from one. We have not tested them ourselves.
Last updated: October 2026. Cordless pressure washers have improved, but they still cost more and run for limited time. This comparison uses Consumer Reports, Greenworks, Zomg and Bob Vila. Greenworks is a vendor, so we treat its figures with caution. We have not tested any of these machines ourselves.
How do they compare in one table?
| Feature | Corded | Cordless |
|---|---|---|
| Runtime | Unlimited near an outlet | 30 to 60 min per charge (Greenworks) |
| Typical cost (Zomg) | Sun Joe SPX3000 $150 to $220 | Greenworks 60V $400 to $550 |
| Noise (Greenworks) | 75 to 85 dB | About 68 dB |
| Power | Consistent (Consumer Reports) | May diminish on big jobs |
| Weight vs gas | Lighter | Lighter |
What does Consumer Reports say?
Consumer Reports says corded gives consistent power, is lighter than gas and is generally cheaper than battery. Battery models are convenient, quieter and emissions-free but can be significantly more expensive, and performance may diminish on big jobs. It adds that the most powerful gas machines can work up to twice as fast as either type.
What do the vendor and blog figures say?
Greenworks Canada claims cordless models reach 2,000 to 3,000 PSI, corded 1,500 to 2,300 PSI, runtime is 30 to 60 minutes and corded costs 30 to 40 percent less. That is manufacturer content, so read it with caution. Zomg compares a $150 to $220 corded Sun Joe with a $400 to $550 Greenworks 60V that runs 20 to 40 minutes at lower GPM.
Which cordless models are worth knowing?
Bob Vila lists the Ryobi 40V Whisper at 2,000 PSI and 1.2 GPM with 45 plus minutes, and batteries are sold separately. Zomg lists a Ryobi 40V at 2,300 PSI for $350 to $450. Our cordless guide and EGO HPW3200 review cover more.
Choose corded if…
- You clean near an outlet.
- You want unlimited runtime.
- You are on a budget.
Choose cordless if…
- You clean cars, RVs or fences away from outlets.
- You already own the battery platform.
- You value quiet, low-fuss operation and can accept limited runtime.
How do you avoid the biggest mistakes?
With corded models, use an outdoor-rated extension cord of the right gauge and keep connections off wet ground. With cordless models, buy a spare battery and charge it before starting. Match GPM to the job, since low flow slows rinse work on both types. Check our how-to guide for setup.
What about gas?
Gas is the most powerful, as our electric vs gas guide explains, but it is loud and heavy.
A simple decision checklist
- Check your outlet access.
- Estimate job length.
- Compare the total cost including batteries.
- Pick GPM for your surface.
- Confirm warranty for tool and battery.
How does total cost compare?
A corded Sun Joe SPX3000 at $150 to $220 (Zomg) is a complete kit. A Greenworks 60V battery model at $400 to $550 may need extra batteries. The Ryobi 40V Whisper’s batteries are sold separately, per Bob Vila. If you already own the platform, the tool-only price can be much lower, so a cordless washer can be a bargain for existing owners. If you are starting from zero, a corded model gives more cleaning power per dollar.
Which jobs favour each type?
| Job | Better fit | Why |
|---|---|---|
| Car washing at the kerb | Cordless | No outlet needed |
| Backyard patio near a socket | Corded | Unlimited runtime |
| Fence line far from the house | Cordless | No long cord |
| Whole-house siding | Corded or gas | Longer session |
| Boat or RV | Cordless | Easy to move |
If a job runs longer than an hour, a corded or gas machine avoids battery swaps.
Are there safety differences?
Corded washers need GFCI protection and careful cord handling near water, and many include a GFCI plug. Cordless machines remove the cord hazard but bring battery care: store packs indoors and charge them as the manual says. Read our safety guide for both types.
