Zoom on the Greenworks PW18HYB
The Greenworks PW18HYB is a light duty pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
With a 13 amp motor, its axial cam pump delivers a pressure of 1800 PSI (roughly 30 times more than a standard garden hose) and a flow of up to 1.1 GPM (values as per PWMA testing standards), resulting in the Greenworks PW18HYB's cleaning power of 1980 Cleaning Units.
The PW18HYB is an electric pressure washer and thus, can be easily started by an ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.
The main draw of the Greenworks PW18HYB is that it is a hybrid pressure washer. Thus, in addition to its corded operation, the unit can also operate cordlessly on batteries, which makes it ideal for cleaning areas with no AC hook up.
For this, you'll need two of Greenworks' pro-grade 60V lithium-ion batteries. Neither these batteries nor their charger are included with the unit. Note that when operating on battery, the PW18HYB max PSI drops to 1500 and max GPM to 1.0, for a total of 1500 Cleaning Units.
Design & Handling
The Greenworks PW18HYB is very mobile, due to its hand truck design and approximate dimensions of D18 x W20.4 x H25.3 in. The strong steel tubing frame assures assembly longevity. The foam-padded fixed handle adds to the PW18HYB convenience of transport, while offering a comfortable grip.
With a weight of only 26.5 lbs, the unit is definitely easy to carry around. On top of its light weight, the transportability and easy of use of this model is further improved by the addition of two 8" never-flat wheels.
The Greenworks PW18HYB's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: A safe detergent storage is facilitated by a removable tank. The Greenworks PW18HYB includes an automatic soap dilution mechanism, which will dilute the detergent using a 7:1 ratio. When a soap nozzle is connected, the detergent will be added automatically to the water.
- Pressure hose: A neat storage for the included 20 ft ⌀1/4" high-pressure hose is facilitated by a set of convenient hooks.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
- Nozzles: The 4 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

The Greenworks PW18HYB's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the Greenworks PW18HYB compare to similarly priced pressure washers.
- The Greenworks PW18HYB, which can achieve a PSI of up to 1800, falls behind the other electric pressure washers in the $195 to $255 price range. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Realm BY02-BIMK with 2600 PSI.
- When compared to devices in the above-mentioned price range, this washer and its 1.1 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 Realm BY02-BIMK, with a GPM of 1.75.
- The PW18HYB ranks as below average in terms of Cleaning Units, compared to electric devices in its price range, reaching only a value of 1980 CU (PSI x GPM). If you consider the highest overall cleaning power as a really important factor, the Realm BY02-BIMK and its 4550 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
As you can see from this interactive chart, when compared to other electric washers between 1500 and 2000 Cleaning Units, the Greenworks PW18HYB is on the expensive side of the price range.
While certainly not the cheapest of its cleaning power range, purchasing it could most likely also mean enjoying the reliability of a high-end product.
