Greenworks Pro Pressure Washer makes quick work of total siding, concrete and brick
We recently got our hands on a GWP2300 Greenworks Pro Pressure Washer. There is always something here that needs to be pressure washed. There was some dirty siding, a dirty car, some concrete and brickwork that was covered in mold and slime for what seemed like eternity, and we took this opportunity to blast some grime back into the depths where it came from.

Key Features of the Greenworks Pro Pressure Washer
Brushless Motor
The GPW2300 has a 15 amp brushless motor that puts out 2.3 gallons per minute at 2300 PSI. From a purely spec-related point of view, these numbers are very similar to Ryobi's brushless models.

It might seem odd to put a brushless motor on a corded tool. Even if run time is not an issue, you get the benefits of longer motor life, no need to change carbon brushes, and better power for the motor size. In fact, Greenworks backs this motor with a 10-year warranty.
JettFlow Technology
The GWP2300 features Smart Flow technology, which they call "JettFlow". What does it mean? Essentially, it's a water pressure sensing technology that responds to the task at hand. Brushless motors require electronic control, so Greenworks takes this opportunity to electronically deliver steady power when you need it.
Turbine nozzle + 4 other nozzles
This pressure washer, like almost every other pressure washer out there, comes with a variety of pressure washer nozzle tips. Includes 15° tip for brick and concrete, 25° tip for siding and PVC, soaping tip for applying cleaner to surfaces and 40° tip for rinsing.

However, the GWP2300 is also equipped with a rotating turbine nozzle. Admittedly, this hint isn't unique to Greenworks, but we haven't seen many of them, but they are very useful. It has an internal swivel tip that blasts out a high-pressure tornado that's great on those tough concrete stains.

Performance
Around the shop, we have a wide variety of surfaces for a good hose. From moldy siding and green fencing to slimy brick walls and blackened concrete, we can't wait to hit town on all surfaces. We even decided to give the car a shower. Here's what we learned:
start up
Brushless motors have some advantages worth mentioning. For one thing, you don't have to bother with gas and oil. This itself has its advantages in terms of avoiding mess and smoke. It also eliminates gas problems for carburetors and other homeowners who only need to use their pressure washer occasionally.

Another thing we really appreciate about this brushless setup is how easy this pressure washer is to start. No need to start the engine and pull this pressure washer. Basically, all you have to do is plug it in, attach the hose, turn on the water, and turn the dial to the "on" position. Very simple.
Accessibility Accessories
We also appreciate the general layout of the Greenworks GWP2300. It has sturdy 10" wheels attached to an open frame/roll cage. The 25' hose stores quickly and easily on the wide cord hook provided, and the power cord is rolled up and stored neatly on the back of the machine. Both the wand and nozzle have their own marking points near the handle, and the nozzle is securely held in place with a rubber grommet.

it's business hours
We have some fences around our office that aren't in the worst shape in the world, but have definitely seen some cleaner days. So we attached the 15° tip and got to work. Without much actual labor, we blasted away the initial mold layer and mildew on the first pass.

We also used this trick for some gooey black bits on concrete slabs. Watching the layers of concrete wash away as you resume cleaning is cathartic.

replacement tips
We used the 25° tip to wash down some metal workshop walls. First off, they're not in terrible shape, but a good spring cleaning never hurts. This trick does a great job of removing any accumulated dust from the walls, making the metal look less dull.

Speaking of things that just need to rinse off built-up layers of dirt and grease, we hooked up the soap head, poured some car wash soap into the reservoir, and gave Tim's caddy a quick spray of soapy water. Then we attach the 40° tip and rinse it all off. The nice thing about this trick is that it has enough power to cut through the dirt, but it also doesn't have so much power that you'll start spraying off the paint and tearing up your trim job.
Pro tip: If you plan to use a pressure washer on your car, use the widest tip you have and start over to avoid damaging the finish.
Finally, we hooked up the turbo nozzle and brought it over some stubborn mold and grime that had accumulated on some of our hardscape. Within seconds, we're able to see the years go by as black and green give way to pristine red.

noise and commotion
One of the great things about using the Greenworks GWP2300 is the sound level it produces. While you're not pulling the trigger, the unit essentially stays powered off and doesn't make any noise. Pulling the trigger gives you about 3 seconds of acceleration, which ends with a powerful bang coming from the hose…without a lot of motor noise.

This is one of the quietest pressure washers we've had the pleasure of using. While that might not mean much for a quick job, our experience in the long haul is that half the fatigue from pressure washing comes to us through our ears. This will not be a problem.
Price
The GPW2300 Greenworks Pro Pressure Washer retails for $299. This is a Lowe's exclusive, so you'll have to pick it up at your local store or order online. It also comes with a 3-year limited warranty on the tool and a 10-year warranty on the motor.
Ryobi's RY142300 runs at 2300 PSI. However, it will work slower due to its 1.2 GPM flow rate.
final thoughts
The GPW2300 Greenworks Pro Pressure Washer isn't quite for heavy-duty, day-to-day Pro use (it's a bit underpowered for commercial projects). However, it's a great option for homeowners who have casual jobs throughout the year and don't want the hassle, noise, and emissions of a gas model.
