Zoom on the Worx WG604
In a nutshell, the Worx WG604 is a light duty pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- cleaning of painted and fragile surfaces
- application of detergent and cleaning solutions
- intense cleaning of hard surfaces
Its power characteristics and design, its main features and all its additional features are presented ahead.
Using a 13 amp universal motor, its axial cam pump delivers a pressure of up to 1600 PSI (roughly 27 times more than a standard garden hose) and a flow of up to 1.3 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 2080 Cleaning Units.
As it is an electric pressure washer, the motor of the WG604 gets easily started by a simple ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.
Design & Handling
Thanks to its hand truck design, the Worx WG604 offers great mobility. The strong metal frame assures assembly longevity. The foam-padded fixed handle adds to the WG604 convenience of transport, while offering a comfortable grip.
Because the device weighs just 28.5 lbs, carrying it around is very easy. On top of its light weight, the transportability and ease of use of this model is further improved by the addition of two 8" never-flat wheels.
The Worx WG604 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Detergent is stored in a 0.33 gal tank. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: The 25 ft high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a convenient hose reel, which also improves its lifespan.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.

The Worx WG604's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the Worx WG604 compare to similarly priced pressure washers.
- The Worx WG604, a device which can produce up to 1600 PSI, is on the lower end of the pressure spectrum, among the electric pressure washers in the $150-170 price range. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Sun Joe SPX4003, which reaches up to 2200 PSI.
- The achievable water flow of this washer, which reaches 1.3 GPM (gallons per minute) can be described as low, compared to other devices in its price range. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the Sun Joe SPX2690-MAX, with a GPM of 1.8.
- The 2080 Cleaning Units (PSI X GPM), of the WG604 result in an average cleaning efficiency, compared to similarly priced electric units. If the highest overall cleaning power is your top priority, the AR Blue Clean AR383, which can reach up to 2850 Cleaning Units, is one of the most efficient of the devices in the current price range.
As you can see from this interactive chart, when compared to other electric washers between 2000 and 2500 Cleaning Units, the Worx WG604 is on the average side of the price range.
Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.
The bottom line
- In the expected price range
- Good range of nozzles included
- Hose reel
- Onboard storage
- Decent CU for the price
- Low PSI for the price
- Low GPM for the price
