Best Greenworks 1500 PSI Pressure Washer

As an Amazon Associate we earn from qualifying purchases.

If you are searching for the best Greenworks 1500 PSI pressure washer, here is the short answer. The Greenworks GPW1501 is an upright, hand-carry electric unit rated at 1500 psi, with a 35 foot power cord and a 20 foot hose. It suits an outdoor cleaning job within reach of an exterior outlet, such as washing vehicles or house exteriors. The listing does not say what its warranty covers, does not name a surface cleaner, and gives two different flow figures, so those points need checking before you buy.

Quick answer

• The listing says this is an AC-powered pressure washer rated at 1500 psi, with a 35 foot power cord that has an inline GFCI.
• The listing gives a 20 foot hose and a weight of 12 pounds, and it says the unit can be used vertically or horizontally.
• The listing gives the flow rate two ways, 1.2 GPM and 12 gpm. Confirm the figure with the manufacturer before you compare it with another model.
• Because the unit is corded, the cord, outlet and water-contact rules matter more here than battery planning, since the listing names no battery.

The product at a glance

The table lists what the Greenworks listing states. Where the listing is silent, the cell says “not stated.” The figures come from the listing text saved for this ASIN on 2026-10-23.

Read the figures as ratings the listing states, not as results on a particular surface. The listing does not explain how the pressure and flow figures work together at the nozzle, so treat the table as a set of stated facts to verify. According to the listing, the footprint is 18.5 inches long, 10.28 inches wide and 8.74 inches high, and the weight is 12 pounds.

Who it suits

This unit fits a homeowner with a working exterior outlet close to the job. The listing describes a 35 foot power cord with an inline GFCI “for use on all exterior outlets,” so the outlet needs to sit within that cord’s reach, and the 20 foot hose sets how far the wand can travel from the unit. Work out that layout before you plug in.

It also suits someone who wants flexibility in how the unit sits. The listing says it “can be used vertically or horizontally for greater stability,” so you can choose the position that suits the ground you are working on. The 12 pound weight is stated in the listing, which makes it a practical figure to consider when you carry the unit to a driveway or a patio. The listing does not say how the unit handles stairs or steep slopes.

Finally, it suits a person whose cleaning jobs stay within the 1500 psi the listing gives as the maximum. The University of Kentucky safety page notes that at home, pressure washers may be used for washing automobiles, house exteriors and other uses. The listing does not name the surfaces it is designed for, so check the surface and the pressure you plan to use against the manual before you start. If you already run a corded Greenworks mower, the same outlet and cord habits apply, and our corded Greenworks mower guide covers that kind of tool.

Storage matters for a corded machine that comes out for occasional jobs. The listing’s dimensions give you a footprint to check against a shed shelf or a garage corner, and the 35 foot cord and 20 foot hose need room to coil when the job is done. The listing does not say whether the unit has a built-in place for the hose or the cord, so look at the product in a store or ask the seller before you plan the storage spot.

This post is written for a buyer who wants a corded unit with its stated figures checked. If your question is whether the machine will remove a particular stain or suit a particular finish, the listing cannot answer it, and neither can this post.

Skip it if

• You need a cordless machine. This listing names AC power and a 35 foot cord, and it names no battery or charger.
• Your work sits beyond the cord and hose reach. The listing gives 35 feet of cord and 20 feet of hose, and it does not describe an extension option. For cord planning, our extension cord guide for electric lawn mowers may help.
• You need hot water or a gas-engine unit. The listing describes neither, and it does not give a water temperature rating.
• You need one confirmed flow rate before you buy. The listing gives 1.2 GPM and 12 gpm, and it does not say which figure is correct.
• You plan to run it on a shared circuit without checking the power requirement. The listing does not state the amp draw, so the manual is the place to check.
• You need to know what the warranty covers. The listing says 3 year warranty and gives no terms.

What the listing does not say

Several points that matter for a buying decision are missing from the listing. The battery and charger line does not apply to the stated AC power, and the listing names no battery. Battery run time does not apply to a corded unit either, but the listing also gives no duty cycle and does not say how long the unit can run continuously.

The flow rate is the most important conflict. The title and first bullet say 1.2 GPM, while the specification table lists a maximum flow rate of 12 gpm. The two figures differ by a factor of ten, and the listing does not explain the difference. Treat the flow rate as unconfirmed until the manufacturer’s manual or support material settles it.

The tank volume of 1.2 gallons appears as a field label without context. The listing does not say what the tank holds, whether detergent, water or something else. The accessories are named in a single bullet: a soap applicator, 2 nozzle tips and an attachable detergent bottle. The listing does not give a full box list, so confirm what ships with the unit before you assume a part is included.

The GFCI deserves its own check. The listing describes the cord as having an inline GFCI for use on all exterior outlets, and it says nothing more about how that GFCI works or how to check it. Read the manual’s instructions for the GFCI before the first use. The listing also does not give the unit’s amp draw, so check the manual before you plug it into a shared circuit.

Motor type, voltage, pump type, water temperature rating, hose material, nozzle sizes and angles, and detergent compatibility are all absent from the listing. It also omits the warranty’s claim process and any exclusions.

How we chose

This post covers one product: the Greenworks pressure washer with ASIN B09LC66PLP, the item matched to the keyword “best greenworks 1500 psi pressure washer.” It is not a ranking. This post does not compare it with other models, and it does not say the unit is the best choice for every job. The listing text was saved from the Playwright scanner on 2026-10-23, and that is the date the listing data was read.

The criteria were plain. The item had to be a single outdoor power tool rather than a set of parts, a manual or an attachment, and it had to be electric rather than gas-powered. The listing also had to state its power source, pressure, hose, cord and included accessories. Pressure washers are written here as outdoor cleaning tools. This product met those criteria, so it is in the post.

Claims were handled in a plain way. Where the listing gives a figure, the table repeats it with the label the listing uses. Where the listing contradicts itself, the post shows both figures and says they disagree. Safety points come from the three safety pages cited at the end of this post: a university safety page, an extension resource and a government occupational safety page. No retail page or review page is used for a fact here.

What we could not verify

• How well this model cleans any surface. The safety and stored-energy pages opened for this post do not cover cleaning results.
• Which flow figure is correct, 1.2 GPM or 12 gpm.
• What the 3 year warranty covers, how a claim works, and whether it needs registration or proof of purchase.
• What the PWMA certification covers for this model.
• The full parts list and whether a surface cleaner is available for this unit.
• Whether the two nozzle tips change the pressure at the spray tip. The listing names 2 nozzle tips and gives no nozzle specification.
• The motor type, pump type, voltage and water supply requirements.

FAQ

Is the Greenworks 1500 PSI pressure washer gas or electric?

The listing gives the power source as AC, and it names a 35 foot power cord with an inline GFCI. It does not describe a gas engine. The voltage is not stated, so check the manual or the box label before you plug it in.

Which flow rate is correct, 1.2 GPM or 12 gpm?

The listing gives both. The title and first bullet say 1.2 GPM, and the specification table gives 12 gpm as the maximum flow rate. The listing does not say which figure is right, so confirm the number with the manufacturer before you compare this unit with another.

Does the listing include a surface cleaner?

The listing does not name a surface cleaner. It names a soap applicator, 2 nozzle tips and an attachable detergent bottle. Ask the seller or check the manual for a complete parts list before you assume a surface cleaner is in the box.

How far can I work from the outlet?

The listing gives a 35 foot power cord and a 20 foot hose. The working distance depends on where you place the unit, and the listing does not describe an extension cord or hose option. The 20 foot hose sets the reach from the unit, so the cord and hose together decide how far the work can sit from the outlet. OSHA advises keeping cords away from heat, oil and sharp edges, and the University of Kentucky page advises keeping the spray away from electrical equipment.

Is an electric pressure washer safe to use near an outdoor outlet?

The listing says the cord has an inline GFCI for use on all exterior outlets. OSHA describes a ground-fault circuit interrupter as one acceptable protective measure when portable tools are used. A GFCI does not replace a check of the cord, so inspect the cord for damage before each use, because damaged insulation can expose energized conductors.

What should I check before the first use?

Read the operator’s manual, examine the hoses and fittings for wear, and make sure nobody stands in the spray path. The University of Kentucky page advises eye and hearing protection and says children should not use a pressure washer. Keep the wand pointed away from people, whether the unit is running or not.

Bottom line

Buy this unit only if an outdoor outlet can keep the work within the 35 foot power cord and 20 foot hose reach, and confirm the flow rate with the manufacturer first, because the listing gives two conflicting figures.
