Pros / The Greenworks GPW1501 is an affordable option that's sufficient for most cleaning projects.

Cons / This pressure washer is one of the loudest we tested, and it can be difficult to move around your project site.

 Verdict / The Greenworks GPW1501 is more affordable than any other electric pressure washer we tested and is good enough for most homeowners to use a couple times a year. However, serious users should look elsewhere.

The Greenworks GPW1501 is the only pressure washer we tested you can buy for under $80 – about half as much as the RYOBI RY14122, the top performer in our tests. It's also the best value electric pressure washer for one reason: It's sufficiently easy to use and powerful enough for occasional light cleaning projects like washing cars and sidewalks.

Because it's the cheapest electric pressure washer we tested, we originally had low expectations for the Greenworks GPW1501. That said, we chose to test it because it had very positive customer reviews on Amazon. After spending some time with it, we decided none of the usability or cleaning issues are bad enough to deter us from keeping it in the garage to use a few times a year. If you plan to use your pressure washer often, a more expensive option, such as the RYOBI RY14122 or AR Blue Clean AR383, will likely be better in the long run.

Our tests showed that this Greenworks machine is powerful enough to wash mud off a car, and by extension, other outdoor surfaces such as patio furniture and wooden decks. However, when we set it to work on a driveway oil stain, it took longer than other pressure washers we tested to have an effect – only the WORX Hydroshot WG629 performed worse in this test. The GPW1501 has a maximum pressure of 1,500 PSI, which is a lot of power, though still below average in our test group.

This is a loud pressure washer. It measured at 91 dB on a decibel meter during tests, a result shared by the Portland 63254, making both units louder than any others we tested.

This pressure washer doesn't have wheels, but it only weighs 19 pounds. As such, it’s easy enough to move around your project site. Without wheels in the way, it's also easy to connect hoses to the machine. Assembly is easy, and the instructions aren't complicated. You only need to pull it out of the box and connect the hoses, handle and wand before it's ready for your first cleaning project.

Most of the usability problems we encountered are caused by the Greenworks GPW1501’s small size. Unlike most of the pressure washers we tested, including the RYOBI RY14122, the GPW1501 isn’t designed like a cart with wheels and a long handle. Although there's a holster to store the wand on the back of the machine, you need to separate the wand into its two halves for it to fit in place. Also, although there's a place to store the hose, there's no corresponding spot to store the power cord on the machine itself. The manual implies you're supposed to store the hose and cord in the same spot, but it's a tight fit.

Greenworks provides a one-year warranty, which is shorter than average for the pressure washers we tested. However, it’s still longer than the 90-day warranty on the Portland 63254, the next-cheapest pressure washer.

The accessories the Greenworks GPW1501 comes with are limited to the essentials: a 20-foot pressure hose, a 25-degree spray nozzle and a 40-degree spray nozzle. These nozzles are good for most cleaning. There's also a detergent tank that snaps onto the handle and stores on the back of the machine when not in use. Since it is so inexpensive, the Greenworks GPW1501 frees up your budget to buy additional accessories.
