The Final output pressure is the most important part of a pressure washer. The higher the pressure, the more powerful the pressure washer is.

Through this feature, you can run a pressure washer at low pressure 1450 PSI and High pressure 2030 PSI. This is one of the most promising features Given in the Upperclass models.

Two pressure setting technology is the most usable: the 1450 PSI is best Suited for the normal dirt, Foam cannon, and car washing, and 2030 PSI is best suited for oil and grease stains or other high pressure outdoor cleaning Jobs.

Motor & Pump

Motor Plays an important role in delivering final pressure because Motor drives Pump and Pump forces the water out. Both the SPX3000 & SPX4000 have the Same 1.45 AMP (1800 watt) universal type motor. 

Both models are compatible with Wobble-plate piston Pump. The Life of this Pump Is Expected 500 Hours by the sun Joe Brand but it runs more than that.


The available length of hose in SPX3000 and SPX4000 is 20 ft. This hose length is a little small compared to their Rival pressure washers. This high-pressure flexible hose is made through good material and it can coil up easily.

Power cord

The Power cord length in Sun Joe SPX3000 and SPX 4000 is 35 ft long. You can use the extension if you want the extra length. This power cord is integrated with GFCI Plug (Ground-fault circuit interrupter). This is the protection device that protects humans from Electric shocks.

This is the best feature that prolongs pump Life. Both the pressure washers have laced with TSS features.
