If this is your first pressure washer, the thing to optimize for is not power. It is the gap between “will clean my driveway” and “will destroy my siding”. Every machine on this page sits in that gap. All five are electric, all five start with a switch, and none of them will cut a groove in a deck board in the two seconds it takes you to realize you are too close.
What I picked for
Four things, in this order. Electric start — a first machine should not involve a choke and a pull cord. A total-stop system, so the pump only runs while the trigger is held, which is both quieter and much kinder to the pump. Enough flow to be useful, because water volume is what actually carries dirt away (see PSI vs GPM). A complete box — a gun, a hose and a set of nozzle tips, so there is nothing to buy before the first Saturday.
What I deliberately did not pick for: the highest PSI at the price. The most common first-purchase regret in this category is a machine that is more powerful than the buyer needed and heavier than they wanted. If you want the reasoning in detail, what PSI pressure washer do I need works through it job by job.
What I left out, and why
Every gas machine. They clean faster. They also need fuel, oil changes, winterizing and a pull start, and they produce pressures that damage siding, wood and cars without much effort. A gas unit is a reasonable second pressure washer and a poor first one. If you think you are the exception — a very long driveway, a large deck, no mains outlet nearby — read electric vs gas and then the gas picks.
The Active 2.0 GPM unit. On paper it is the most interesting electric here: more water than anything else at a modest pressure, which is exactly the right trade. It is sold tool-only, so you also buy a hose, a gun and tips, and the real cost lands above several gas machines. Excellent second machine, wrong first one.
How to choose between these five
Start with what you are cleaning. Mostly the car, some furniture, a small patio: the Greenworks 1600 or the Ryobi 1800. You cannot easily hurt anything with these and they store in a closet. A driveway and a deck, plus the car: the Sun Joe SPX3000 or the Westinghouse ePX3050. A long driveway and you want it over quickly: the Westinghouse ePX3500, which is about as much as a household outlet will give you.
Then check one number: GPM. If you expect to buy a surface cleaner — and anyone with flat concrete should — you want 1.6 GPM or more. The two Westinghouse units are at 1.76; the Greenworks and Ryobi are at 1.2, which limits you to an 11-inch head.
What to buy with it
Three things, and the total is less than the difference between two of these machines. A longer hose so you move the gun instead of the machine. A bottle of detergent, because the chemicals do most of the work people credit to pressure. And an inlet water filter, which is a few dollars and protects the part of the machine that actually fails. The full list, including what to skip, is in the starter kit page.
Before the first use, spend two minutes on the setup sequence and the safety basics. Most damage done with these machines happens in the first hour of ownership.
