Sun Joe SPX3000 vs Greenworks GPW1501: The $50 Question That Actually Has a Right Answer
These are the two most-purchased electric pressure washers under $200. The Greenworks is lighter, cheaper, and perfectly adequate for washing a car or cleaning patio furniture. The Sun Joe delivers 35% more pressure, includes a dual soap tank system, and is the one you want if your list includes a driveway, deck, or siding. The $50 difference is worth it if you have anything harder than a car to clean. It is not worth it if you don't. This page gives you the data to make that call in five minutes.
Quick Verdict
- →You have a driveway, deck, siding, or house exterior to clean: Get the Sun Joe SPX3000. The extra 530 PSI and dual soap tanks are worth the $50 premium.

- →You want the lightest possible machine: Greenworks at 17 lbs is the winner. The SPX3000 at 24 lbs is 41% heavier.

The Feature That Actually Separates Them: Dual Soap Tanks
The PSI difference (2030 vs 1500) is real — it's about 35% more pressure and the difference between marginal and confident on a concrete driveway. But the feature most buyers notice in practice is the dual soap tank system on the SPX3000.
Two 0.9-liter tanks mounted on the machine. You load different soaps in each (say, car shampoo in tank A, deck cleaner in tank B) and switch between them with a dial. Switch the machine to soap nozzle, apply detergent, let it dwell, then switch to a pressure nozzle to blast it off. No stopping to pour soap, no single-use soap bottles, no carrying a separate detergent container around the yard. The Greenworks has no equivalent — you either hand-apply soap first or use a separate foam attachment.
If you're washing a car and not using soap at all, this doesn't matter. If you're doing any kind of multi-surface cleaning session, it matters a lot.
