Best Greenworks Pressure Washers (2026)

Greenworks tops its range here with a 14 amp TruBrushless motor generating 3000 PSI and up to 2.0 GPM, and, unusually, says the pressure and flow claims were verified by an independent lab. JETTFLOW technology is described as adding up to 50% more flow for quick rinsing and reaching high areas, which is the figure that matters on a deck or a wall.

The flow is a maximum, and the product of 3000 PSI and 2.0 GPM, 6,000, is a ceiling, but even at a lower real figure it is a step up from the 1.2 GPM machines lower in the range. Against the 2700 below, you get higher pressure at slightly lower maximum flow, so the 3000 is the stain machine while the 2700 is the rinse machine.

As with all axial cam pumps in the range, the pump is not rebuildable, so protect it: never run it dry, use clean water, drain it before freezing weather and keep the inlet screen clean. Keep a 25 or 40 degree tip on wood and siding, and save the narrow tips for concrete.

The 2700 trades 300 PSI of top pressure for 0.3 GPM more flow than the 3000, and the listing says the flow varies from 1.2 to 2.3 GPM depending on the setting, which is a frank way to say the maxima do not apply together. The TruBrushless motor is described as adapting power automatically for maximum cleaning, which is the system's way of trading pressure and flow as the load changes.

For a big deck or a long fence, the higher flow range is the more useful number, because rinsing cuts the time of the job rather than blasting any single spot harder. Compared with the 3000, this one is the choice when speed across area matters and the stains are moderate. Compared with the Pro 2300, it is a step up in pressure with a similar flow ceiling.

The push-button start keeps things simple. Because the brushless motor runs at higher duty than the entry units, let it cool before you coil the hose, and keep the inlet screen clear so the pump never runs starved. Use the soap nozzle at low pressure, and rinse from top to bottom so you do not re-dirty cleaned areas.

The Pro 2300 is the one that pays attention to detail: a TruBrushless motor paired with Smart Flow pressure-sensing technology that adjusts the supply, a kink-resistant 25-foot hose and a 35-foot power cord with an inline GFCI for use on exterior outlets. Jet Flow technology is said to add 50% more flow for rapid rinsing and high-area reach.

The listing says it carries an SGS certification, a third-party testing mark, which gives some comfort on the figures. At 2300 PSI and 2.3 GPM, it is the flow-first machine of the range, similar to the 2700 but with less top pressure. It is the logical choice if your main jobs are decks, fences, cars and siding, which reward rinse volume over raw pressure.

Ownership is typical axial cam: protect it from dry running, drain it before freezing weather and clean the inlet screen. The large wheels listed make it easy to roll around, and the inline GFCI is a real safety feature on a wet job.

A built-in detergent tank and on-board nozzle storage are the practical features here: you fill the tank, switch to the soap nozzle and walk the deck with no separate bottle to carry. Five interchangeable nozzles, from 0 degrees for tough stains upward, cover the usual range of jobs.

The 1.2 GPM flow is the same as the cheaper models, so the 2200 is a pressure step, not a flow step, and driveways, patios and vehicles are what the maker lists. Compared with the 2000 below, you get 200 more PSI and the tank, and compared with the Pro 2300 you get far less flow but a simpler build.

Flush the detergent tank after each use, avoid leaving cleaner in it between jobs and keep the nozzles organized in the on-board holder. Drain the pump after every session, particularly before cold weather.

The 2000 PSI model is the practical middle of the lower range, rated to PWMA standards, the pressure washer industry's test method. Its listed uses, patio furniture, grills, walkways and vehicles, are exactly what a 2000 PSI, 1.2 GPM machine does well.

At about 2,400 as a pressure-times-flow figure it is a perfectly honest light-to-medium machine. Against the 1700 and 1800 models below it in the range, you gain pressure headroom for dirtier surfaces, while the flow stays the same. Against the 2200 it lacks the detergent tank.

Keep it simple: drain the pump after use, coil the hose loosely and replace the quick-connect o-rings if they weep. Use wide tips on vehicles and wood and keep the narrow ones for concrete.

The bottom rung of this guide is also the easiest to live with: a push-button start, an integrated GFCI that cuts power if a fault occurs, and a gentle 1700 PSI at 1.2 GPM that is hard to misuse on cars, trucks, motorcycles, boats, RVs and patio furniture. There is no gas, no oil, no spark plug and no pull cord.

The cost is headroom: for anything with ground-in dirt, the higher rungs do better, though not as much as the labels suggest since the flow is the same. Against the 2000, you lose 300 PSI, and against the 3000 you lose more than half the flow capacity.

To keep it going, drain the pump after use, avoid kinking the hose and store it indoors. It is a sensible first machine for someone who wants to learn without risking paint or wood.

The 1800 is the lowest-flow machine in the range at 1.1 GPM, and its distinguishing feature is a PWMA certification, which means its pressure and flow were rated by the industry test method rather than just printed on the box. For a light-duty machine that is a useful reassurance, because the figures are what the machine actually does.

Its listed uses are cleaning cars, trucks, motorcycles, boats, RVs and outdoor patio furniture, which is a fair brief for roughly 1,980 pressure-times-flow units. Compared with the 1700 it has 100 more PSI and a touch less flow, so the two behave almost alike on a driveway, and the certification is the main reason to choose one over the other. Against the 2000 it lacks the pressure headroom for tougher grime.

Push-button start and an integrated GFCI keep the routine simple, with no gas, oil, spark plugs or air filter to maintain. The sealed GFCI plug is the part to watch: keep it off wet ground, and dry the prongs before storing the cord on the hook.
