Zoom on the Worx WG604
In summary, the Worx WG604 is a light duty pressure washer, that offers an all-around versatile cleaning experience, and also:
- cleaning of painted and frail surfaces
- applying detergent and cleaning solutions
- intense cleaning of hard surfaces
Powered by a 13 amp universal motor, its axial cam pump can deliver a pressure of 1600 PSI (around 27 times more than a standard garden hose) and a flow of up to 1.3 GPM (values claimed by the manufacturer). Combined, these values mean that the Worx WG604 has a cleaning power of 2080 Cleaning Units.
Being an electric pressure washer, the Worx WG604'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
The Worx WG604 is very mobile, due to its hand truck design. The strong metal frame assures assembly longevity. The foam-padded fixed handle adds to the WG604 convenience of transport, while offering a comfortable grip.
With a weight of only 28.5 lbs, the unit is very easy to carry around. 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.
Along with the Worx WG604 itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: A safe detergent storage is facilitated by a 0.33 gal tank. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- Pressure hose: A neat storage for the included 25 ft high-pressure hose is facilitated by a convenient hose reel, which also improves its lifespan.
- Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.

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 compared to similarly priced pressure washers.
This unit is now discontinued, but used to be sold around $170.
- The Worx WG604 with its 1600 PSI achieved a lower pressure value, compared to other electric pressure washers in the $150-180 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) could be described as low, compared to other devices in its price range. In case you are looking for a device which can most efficiently rinse away debris in the current price range, the Sun Joe SPX2690-MAX has the highest GPM of 1.8.
- In comparison to other electric units of similar price, the 2080 Cleaning Units (PSI X GPM) of the WG604 were average. If the highest overall cleaning power is your top priority, the AR Blue Clean AR2N1, which can reach up to 2870 Cleaning Units, is one of the most efficient of the devices in the current price range.
