For each machine, we pulled the trigger on the spray wand for thirty seconds and weighed the water to calculate the true GPM rating. The simplest way to categorize pressure washers is by their PSI, or pounds per square inch, rating and fitting them into three groups. Higher PSIs usually mean higher price tags and better cleaning power. Overall, this pressure washer feels lower in quality than the others. The other electric models are made of mostly plastic too, but it really stands out on this machine, to the point of being almost toy-like. There’s a glimpse of hope for higher-quality parts with the water-supply hookup port, but it turned out to be just chromed plastic and not a stainless steel part.
It only registered 73.3 decibels on the sound meter while in operation and a mere 63.8 decibels at 25 feet away. Our cleaning units measurement for the Westinghouse was a whopping 5980, which is over a thousand points higher than the Simpson. When we hooked it up to our testing trough, this washer was able to sustain a bocce ball at 6.5 feet on a 24-degree incline. To get a more tangible sense of spraying power, we built a wooden trough adjusted to an angle of 24 degrees to see how high each washer could spray a standard bocce ball.
It has a built-in detergent tank with an adjustment knob that controls how much detergent is mixed with water. You also get a hose drum mounted right underneath the carry handle. This allows you to store the pressure hose in a tidy way without wasting too much time folding it around with your hands or dangling it off a hook.
We read reviews about people melting their high-pressure hoses on the engine when they weren’t careful. While this is definitely something you should note, it certainly isn’t a deal-breaker. This lightweight pressure washer is user-friendly, can cut through tough grime, stains, and paint, and can be taken anywhere. This pressure washer also sun joe spx 3000 has a brushless induction motor that runs more efficiently and quieter than other models. Disconnect the spark plug wire then pull the recoil handle 5 – 6 times to remove water from inside the pump. Of water flow, the ePX3000 has the muscle to scrub up decks, sidewalks, and fencing to cars and patio furniture with pure scouring force.
Anything between 1500 to 2000 psi is more than enough to clean your car or driveway. And 1.5 to 1.8GPM of flow rate is plenty unless you’ve got a really large deck or boat to clean. Most electric pressure washers these days come with onboard tool storage and features like hose reels, and you can decide whether these extras are worth it for you. The ePX3000 doesn’t have a bunch of fancy add-ons but it does pack the most performance per pound compared to any other electric pressure washer I’ve ever seen.
