What does Zomg conclude?
Zomg compares the corded Sun Joe SPX3000 with a Greenworks 60V battery model. It says Sun Joe is better value for most homes and that Greenworks makes sense only if outlets are a problem or you already own 60V tools.
What does The Lawn Review conclude?
The Lawn Review compares the corded Greenworks Pro Brushless with the Sun Joe SPX4600. It picks Greenworks for warranty, GPM and price, and notes a cracking plastic hose fitting on the Sun Joe SPX3000.
Why do the verdicts differ?
Because each review uses a different Greenworks model. A corded brushless model with 2.3 GPM beats Sun Joe on flow and warranty, while a battery model costs more and has lower GPM. Always check which Greenworks you mean.
Which is better for what?
- Lowest price with an outlet nearby: Sun Joe.

What are cleaning units and why do they matter?
Cleaning units equal PSI multiplied by GPM. Zomg lists 3,573 for the Sun Joe SPX3000 and 2,760 for the Greenworks 60V model, which explains why the corded Sun Joe feels faster despite lower PSI than some rivals. The Greenworks Pro with 2.3 GPM at 2,300 PSI would come to about 5,290 by the same maths. Use this number to compare machines, but remember it hides differences in nozzle and pump quality.
How do runtime and cords affect the choice?
A corded machine runs as long as you have power. Battery Greenworks models are limited to 20 to 40 minutes in Zomg’s listing, so large jobs need spare batteries. If you plan to wash a car, an extension cord may be more convenient than a battery, provided it is outdoor rated and long enough. For driveway-scale jobs, check our driveway guide.
A simple decision checklist
- Choose corded if you have an outlet nearby.
- Compare GPM, not only PSI.
- Check the hose fitting quality reports.
- Compare warranties: 10-year motor coverage on the Greenworks Pro versus 2 years on the Sun Joe SPX4600.
- Buy the exact model you researched.
What do owners commonly complain about?
The Lawn Review mentions a cracking plastic hose fitting on the Sun Joe SPX3000, and TechGearLab notes the Greenworks GPW3002 is heavy at 47.6 lb. Check hose fittings when you unbox any model, tighten them by hand and inspect them each season. A heavy machine may be tiring to move around, so look at wheel size and handle design. Store either brand indoors during freezing weather so the pump is not damaged.
