Zoom on the Sun Joe SPX9004-PRO
In a nutshell, the Sun Joe SPX9004-PRO is a light duty pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- spot cleaning of hard, unpainted surfaces or high reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
Its axial pump, which utilizes a 13.5 amp motor, may deliver a pressure of up to 1000 PSI (almost 17 times more than a standard garden hose) and a flow of up to 1.8 GPM. These values correspond to a cleaning power of 1800 Cleaning Units.
Since it is an electric pressure washer, the motor of the SPX9004-PRO is started simply by an 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 L18.1 x W10.5 x H12.3 in, the Sun Joe SPX9004-PRO makes mobility one of its core strengths. The handle adds to the SPX9004-PRO convenience of transport.
With a weight of only 43 lbs, the unit is definitely easy to carry around. This is, in part, thanks to its plastic frame, which allows it to remain as lightweight as possible. Because the SPX9004-PRO is so lightweight, it doesn’t utilize wheels.
Along with the Sun Joe SPX9004-PRO itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. It must be noted that the Sun Joe SPX9004-PRO doesn’t come with a soap dilution mechanism. Therefore, you must always make sure that your detergent is correctly diluted. The detergent is automatically added to the water when a soap nozzle is connected.
- Pressure hose: This washer comes with an easy-to-connect 25 ft high-pressure hose. However, it doesn't feature any proper storage solution for it (no reel, strap or hook).
- Spray gun and wand: The device comes with a classic ergonomic spray gun and a wand.
- Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

- Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage) and a trigger lock mechanism (which prevents accidental operation).
