Description

Zoom on the Greenworks GPW1501

In summary, the Greenworks GPW1501 is a light duty pressure washer, that offers an all-around versatile cleaning experience, and also:

  • cleaning of painted or delicate surfaces

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The Greenworks GPW1501 in use

The Greenworks GPW1501

Its axial pump, which utilizes a 13 amp universal motor, may deliver a pressure of up to 1500 PSI (almost 25 times more than a standard garden hose) and a flow of up to 1.2 GPM. These values correspond to a cleaning power of 1800 Cleaning Units.

Being an electric pressure washer, the Greenworks GPW1501's motor can be easily started by a convenient ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

With its portable design and approximate dimensions of D10 x W12 x H17.7 in, the Greenworks GPW1501 makes mobility one of its core strengths. The handle adds to the GPW1501 convenience of transport.

The unit can be very easily carried around, as it weighs just 18.4 lbs. This is, in part, thanks to its plastic frame, which allows it to remain as lightweight as possible. This light weight compensates for the fact that the GPW1501 doesn't have any wheels, as it's not something necessary.

Main Features

The Greenworks GPW1501 in use

The Greenworks GPW1501

The Greenworks GPW1501 comes with a spray gun, a wand, a pressure hose, 2 nozzles and a detergent addition feature, which are detailed below.

  • Soap addition: Detergent is added to the water at the exit, by attaching the included foam cannon to the end of the gun. The Greenworks GPW1501 is not equipped with a soap dilution mechanism, and thus, it is up to the user to ensure the detergent’s correct dilution ratio when using it.
  • Pressure hose: The 20 ft ⌀1/4" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of easy-to-use straps.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a dedicated slot.
  • Nozzles: The following table illustrates the 2 included nozzles, along with the surfaces which they are the most suitable for.

The Greenworks GPW1501's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Greenworks GPW1501 compare to similarly priced pressure washers.

  • The Greenworks GPW1501 with its 1500 PSI achieves a lower pressure value, compared to other electric pressure washers in the $60-90 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the WEN PW19 that can reach up to 2000 PSI.
  • When compared to devices in the above-mentioned price range, this washer and its 1.2 GPM (gallons per minute), is on the lower end of the achievable water flow. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the WEN PW19, with a GPM of 1.6.
  • The GPW1501 ranks as below average in terms of Cleaning Units, compared to electric devices in its price range, reaching only a value of 1800 CU (PSI x GPM). When it comes to the highest overall cleaning power in the current price range, one of the products at the very top currently is the WEN PW19 and its 3200 Cleaning Units.

As you can see from this interactive chart, when compared to other electric washers between 1500 and 2000 Cleaning Units, the Greenworks GPW1501 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget pressure washer.
