Greenworks Pro GPW1501 Electric Pressure Washer

The GPW1501 is a 13-amp corded electric pressure washer with a universal (brush) motor — confirmed by multiple independent review sources. TechGearLab's independent test measured approximately 1,428 cleaning units at practical flow, lower than the 1,800 CU implied by the 1500 PSI × 1.2 GPM label but within the range that handles routine dust and light road grime on a regularly maintained car. The 1/4" quick-connect fitting accepts standard foam cannons — the owner-review base is still modest, but owners report using a foam cannon for driveway car washing at this unit's 1.2 GPM flow rate. At 15.5 pounds with an upright hand-carry form factor, it's one of the lightest in the category, making it easy to move around the vehicle. The 35-ft GFCI cord provides a meaningful range from the garage outlet.

This is a good match for the occasional car washer who wants a foam cannon setup without spending on a brushless motor unit. The 20-ft hose reaches most panels on a sedan or SUV without repositioning the unit. Skip it if you plan to wash heavily contaminated vehicles regularly (road salt, heavy brake dust, off-road grime) — the 1,428 CU measured output is on the lower end for demanding situations. Buyers who wash multiple vehicles weekly, need concrete cleaning alongside car washing, or want the long-term durability of a brushless motor should consider the Greenworks GPW2700 instead.

CSA certification is mentioned in some product descriptions for the GPW1501, but no listing number was confirmed in the CSA Group public directory at the time of this review. GFCI protection on the 35-ft cord is confirmed by the manufacturer. No active CPSC recall applies to the current production run — a 2021 Greenworks/Powerworks spray gun recall (CPSC Recall 21-105) covered GPW1501 units manufactured between January 2017 and May 2020 only; the current ASIN reflects post-recall production with an updated spray gun design. Dispose of via municipal e-waste programs (Best Buy drop-off, municipal hazardous waste events) at end of life — no lithium battery to manage separately.
