Our Verdict

The Greenworkds Pro 3000PSI comes with some serious cleaning power. It earns some of the most impressive pressure per square (PSI) inch and cleaning unit numbers of the test. It has one of the highest cleaning units of any electric pressure washer. Unfortunately, that doesn't translate directly to cleaning power. In addition, its fairly loud compressor, plastic wheels, and more challenging balance point give us pause. Especially when you consider those flaws alongside its high price tag. We like this machine, but don't feel like it offers enough value for us to recommend it.

Cleaning


When you buy a pressure washer, you want it to be good at cleaning. That's why we rate these machines' cleaning test results as a full 45% of their final scores. To measure their scouring skills, we ran three separate tests — timed carpet cleaning, measuring their cleaning units, and our very own bocce ball pressure test. We used the washer's most focused and powerful 15-degree nozzle for these tests. This unit comes with 15, 25, and 40-degree nozzles, as well as a soap and turbo nozzle.

The carpet cleaning test is a subjective one. Though we did time how long it took us to clean each section of charcoal-covered carpet — so it does include some hard data. The Greenworks Pro 3000PSI is one of the most powerful electric options we've tested. Cleaning the carpets in under four and a half minutes in our tests. That's over a minute slower than the best gas-powered options.

To measure cleaning units (CUs), which are an industry standard, we took a PSI reading using an inline pressure gauge. It blew us away with a reading of 2,300 PSI.

To calculate the Greenworks CU, we multiply that 2,300 PSI by how many gallons of water the washer sprays in a minute. In this case, 1.27 gallons, for a CU of 2,921. That's 768 CUs above the test's average. But that doesn't tell the whole story.

In the bocce ball test, we used this machine to blast it up a 24-degree angle ramp and measured how far it went. The answer is 3 feet, which is quite a bit lower than the other washers with outstanding PSI numbers, suggesting that this machine has less raw power than you would expect.

Portability


The Greenworks is a little less impressive from a portability standpoint. It's easy to pull, with a handle that is at a nice height and plastic tires with a bit of grip to them. But the wheel placement and resulting balance point make it harder to push.

We also prefer the give and grip of rubber tires, though these work fine to roll over easy surfaces like pavement and grass. At 47.2 pounds, this machine is not exactly light, and we don't love hefting it over uneven terrain or in and out of vehicles.

We do appreciate how easy this pressure washer is to store. You can lay it flat or leave it vertical to fit your needs. We also pay close attention to how securely you can store the wand. This washer provides a secure clip that keeps it protected in place as you move it around. The same is true for the hose, which is held in place with an elastic band.

Noise


We set up a sound pressure level (SPL) meter beside each machine while it ran and then again 25 feet away. The comparative results accounted for 15% of the washers' final scores.

The Greenworks is fairly loud up close at 76.8 dBa, which are decibels adjusted to the range of human hearing. It sounds something like a busy downtown street. For comparison, the quietest machines register around 70 dBa from this distance, and the loudest is an ear-popping 93.9.

From 25 feet away, the SPL meter registered 67.9 dBa. That's a little bit quieter than a vacuum cleaner or an alarm clock. The loudest machines from this distance are more like 80 dba, and the quietest around 60.

While those numbers are reasonable, we wish the Greenworks compressor turned off when we aren't using it as many other electric options do. This one stays on the whole time, though it does shift to lower, slightly quieter rotations per minute (RPM).

Ease of Use


The last 10% of the final score is how easy each pressure washer is to use. The Greenworks fares well here. It comes with a flexible 24' hose that is easy to roll and handle. This is much less common than we'd like it to be. It's also easy to store the hose on a wide hook with an elastic clip to hold it in place.

There is only one quick connection fastener on the machine, which lets you plug the hose into the spray gun, skipping the normal hose attachment ritual of screwing in the threads. We wish it had more. The gun also leaks occasionally, though only a small amount.

While the area around the garden hose input connection is fairly easy to access, there is a metal bar in the mix that can get in the way at certain angles. The 36' electric chord gives you room to move around, and there is a convenient storage area for it in the back.

The great thing about electric pressure washers is that they don't require the oil, gas, and regular maintenance that a gas motor does. Their plug-and-play nature makes them inherently easier to use.

This machine is good at keeping itself together with easy-to-use and effective storage mechanisms for the wand, hose, and electric cord. It's also easy to store with a sturdy base that you can lay flat or leave vertical.

If you want to clean with soap, you can put it in a massive onboard storage tank through the side of the machine.

Value


Though the Greenworks Pro 300PSI offers impressive performance, its relative expense keeps us from recommending it. We think some options offer a better value.

Conclusion


The Greenworks Pro is a powerful electric pressure washer that finishes jobs in a hurry. But don't we think its high price tag, relatively loud engine, and less than ideal portability are necessarily worth it.
