This unit is specifically made for Lowe’s and was hand delivered with a Local shop. It arrived in a moving truck and was hand carried by the transferring team to my garage. The box had no harm whatsoever and all the contents came unscathed.

Assembly Instructions Could be Clearer

The written assembly instructions for this Greenworks pressure washer Weren’t really beneficial. The image diagrams were better, but not great.

The written instructions do not clearly say which pieces are contained And where these bits should go to correctly assemble the unit, so I mostly relied upon the diagrams when placing the device together. Although I’ve assembled a lot of pressure washers, I had to look very closely in the diagrams and maintain rechecking them to make certain all the screws moved in the right holes. My big concern was using the incorrect screw in the wrong hole and stripping the threads.

The assembly process comprised:

    • Including the two 8″ wheels,
    • assembling the front panel and spray wand”rifle” holder,
    • including the electrical cable and high-pressure hose hangers, and
    • installing the handle bars to the lower stanchion tubes of the pressure washer frame.

I then hung the electrical cord on its own committed hook and did exactly the same Using the nozzle hose. I hooked up the high-pressure hose to the pressure washer , built the spray wand rifle and hooked the other end of high-pressure hose into it. I cut the gun to the rifle holder situated on the handle bar frame.

Four Pressure Washer Nozzles

Cleaning power and the speed in which you can clean a room with a Pressure washer is a function of water flow (measured in gallons per second, or GPM), nozzle spray pattern, and pump pressure (PSI). When I wanted a system that cleaned large areas quickly, then I’d be looking at a semi-commercial or skilled version — which can costs hundreds of dollars over a machine like the Greenworks 1800 PSI Electric Pressure Washer GPW 1803.

There is a misnomer that just because you have the same PSI means That you have the same cleaning speed. You may use the exact same spray nozzle and have the same strain, but also the water flow rate for a commercial manufacturer will be much higher, thereby providing you with the ability to clean faster.

Pressure washer. With its added variety of nozzles (under ) it can do a broad assortment of cleaning tasks, from washing cars to stripping paint (at a slow speed ).

Here’s what Greenworks includes on this package so Far as nozzles:

Soap (black) — The”soap spray suggestion” is utilized to distribute specialized cleansers onto to a surface prior to being pressure washed. The detergent (only use one that is especially formulated for pressure washers) is sprayed at low pressure and assists strip grime and dirt from the surface. The soap nozzle fits into the end of the spray jar like some of the other nozzles.

Turbo (black) — A 0º into 15º spray pattern. Its principal advantage is that it can clean around 50% quicker than a traditional fan tip nozzle. With the Greenworks GPW 1803 pressure washer, the turbo nozzle also includes a 0º to 15º spray pattern so you don’t need different dedicated tips to perform the tasks that require those more narrow sprays.

Be careful with the turbo nozzle; if it’s held too close to a milder Material (such as wood furniture) it can cut grooves into the wood.

A nice feature of the Greenworks unit is that the nozzles are Tagged as to their program. For example, it clearly reveals with a 40º nozzle for washing automobiles (this can consist of boats, RV’s and comparable vehicles).

NOTE: Paint finishes, like individuals on RVs, automobiles, boats, etc. can be Damaged when using the incorrect nozzle holding the spray nozzle too close to the surface


There Are Many cautionary and warning labels sprinkled throughout It’s easy to unwittingly inflict damage on others or yourself.

  • Here are some principles (but maybe not all of them):
  • Never point the spray gun at a bystander or pet.
  • Do not use in wet or rainy conditions (because this is an electrical device).
  • Before altering the nozzle, then switch off the machine, then launch any tension in the high-pressure hose by pulling the gun’s trigger, and set the handle lock-out mechanism in place.
  • Hold the spray gun in the hands, one on the trigger handle and you on the batter. Don’t work with one hand, as the blowback force may cause you to lose control of the gun.
  • Never do maintenance without turning the device OFF (and unplugging it) and releasing any tension in the pump and high-pressure hose/gun.
  • Do not leave the device outside in freezing temperatures.
  • Read the Owner’s Manual entirely for performance, security and maintenance procedures.

Hooking Up The Water Source

Before I grabbed my gun and started my testing, I needed to hook up the garden hose. It’s very simple to attach it into the hose connector over the face of the machine.

Connecting The Right Nozzle Tip

The first thing you need to determine is that nozzle to utilize. After I Made this choice I inserted it to the”fast connect” brass fitting in the end of the spray gun. All nozzles that have the machine are fast connect compatible.

The important thing is to make sure the nozzle is seated properly To the fast connect brass tip at the conclusion of the spray gun, otherwise, you are going to fire the nozzle off the spray wand and probably never find it again.

The key to seats the nozzle tip is to pull on the brass quick link Collar back and slip the nozzle inside the collar. Pull the nozzle toward you as you push the brass collar (from you) back on the nozzle’s male metal finish. Give the nozzle a fantastic tug to make certain that it is secured in place. And that is it, you’re all set to go.

How Did It Perform?

Using the Soap Nozzle & Dispenser

I started using the soap dispenser nozzle and integrated detergent tank on the front of the unit. The 400 soap nozzle applies soap at low strain (not use soap using a high-pressure nozzle).

The soap tank on the front of this Greenworks 1800 PSI Pressure Washer GPW 1803 automatically mixes the detergent with water. That is a big help; you do not have to be concerned about diluting the concentrate and figuring out all the math to get the score right.

When Purchasing pressure washer soap, I prefer the stuff that I don’t Have to dilute. Just make certain that you read the instructions on the pressure washer bottle before buying it. In some cases, concentrated soaps must be diluted before they’re poured into the soap dispenser tank.

I like that the soap tank onto this unit is on front of this Pressure washer, is readily accessible, and includes a massive cap (so it’s easy to pour in the detergent out of a bottle without spilling).

After employing the soap to my car and letting it sit for the Manufacturer’s recommended time (be careful to not let it dry as it will leave streaks), I changed over to the 400 nozzle and began to wash off the soap. The detergent must do a lot of the job and operate in combination with the nozzle. You can get in trouble with a pressure washer in a rush if you are just relying upon the high-pressure nozzle to do the job (so, for instance, don’t use a 250 angle nozzle for washing your vehicle and other such as vehicles).

Both the soap nozzle along with 400 nozzle functioned nicely. As far as Automobile washing performance is concerned, the GPW 1803 it did a very wonderful job and I was pleased with the outcome

Employing the High-Pressure Nozzles

To begin with , I tried that the turbo nozzle. It worked like a charm cleaning up a Moldy region of my concrete walkway. I was also able to burst small regions of peeling paint outdoor furniture using the turbo nozzle.

Next, I attempted the 25º traditional fan nozzle onto the moldy concrete. It also blasted off the mold effortlessly. It took longer than the turbo nozzle but did an equally effective job. It did not take peeling paint off though.

Using the 0º spray placing on the turbo nozzle, I managed to To eliminate stains from hard to reach places, such as areas and cracks that would have been out of reach.

Overall, I was very pleased with the cleaning outcomes It worked well washing my walls, cleaning the car, eliminating mold from my concrete walkway, stripping flaking paint out of outdoor wood furniture, and even reaching second narrative areas together with all the 0º nozzle

Tangled And Kinked High-Pressure Hose

Of all the pressure washers I’ve tested, I found this high-pressure Hose the toughest to take care of. It had been difficult to coil and uncoil (even if not connected to the gun). I used all the suitable coiling methods, such as laying out the hose in a straight line and twisting the nozzle as I coiled it, but it just would not coil readily. Additionally, it tended to kink a fair amount, especially if I had a coil in the line and pulled the hose to my job area.

All this occurred despite the fact that I was using it at temperatures in the 800 F range, so the hose was fine and pliable.


Three-year limited lifetime warranty against defects in materials and workmanship.

Together with the GPW 1803, Greenworks includes a pleasant 1800 PSI pressure washer With a few notable features. Plus, it is Pressure Washer Manufacturers’ Association (PWMA) Certified.


It does a Fantastic job powering through typical pressure-washing tasks, Like washing a vehicle, cleaning a driveway, and draining small areas of peeling paint (slowly).

But, I found the high-pressure hose difficult to take care of. To Uncoil it, I had to disconnect it in the gun. To coil it up, I had to detach it from the gun as well as the machine and put it out in a straight line. Additionally, it had a propensity to kink.

Be carried out with it. Yes, you’ll pay more cash to make this conversion, But I found the convenience and functioning of this Flexzilla hose created The Greenworks 1800 PSI Electric Pressure Washer GPW 1803 a better machine.
