Zoom on the Sun Joe SPX9004-PRO
In summary, the Sun Joe SPX9004-PRO is a light duty pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, unpainted surfaces or high reach areas
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
Powered by a 13.5 amp induction motor, its axial pump can deliver a pressure of 1300 PSI (around 22 times more than a standard garden hose) and a flow of up to 2 GPM. Combined, these values mean that the Sun Joe SPX9004-PRO has a cleaning power of 2600 Cleaning Units.
The SPX9004-PRO 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.
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 very easy to carry around. Among other factors, the plastic frame plays a role in this light weight. This light weight compensates for the fact that the SPX9004-PRO doesn't have any wheels, as it's not something necessary.
The Sun Joe SPX9004-PRO comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. However, since the Sun Joe SPX9004-PRO does not feature a soap dilution mechanism, you'll have to make sure your detergent is correctly diluted before use. The detergent will be added automatically to the water when a soap nozzle is attached.
- 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 following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

- Wall-mountable: The unit can be stored on the wall thanks to a wall mount kit (not included). This is a welcomed feature when we need a neater storage solution or to clean the same area regularly (garage, barn, workshop, storage room, etc.)
- 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).
- Accessories: The Sun Joe SPX9004-PRO comes with an owner's manual (opens in a new tab) and some basic documentation to get you quickly started. On top of that, you also get spray gun, nozzle cleaner, pressure hose, wand and power cord.
