Sun Joe SPX4000 Washer: Getting into the details!

Now that I have given you a basic idea of what the Sun Joe Green Electric Washer is about, let’s dive in deeper. 

Here are my favorite aspects of this rugged charmer: 

Adjustable Pressure Settings:

Sun Joe’s most unique feature is that you can change how strong you want the pressure to be. 

When doing a regular cleaning job, the low pressure of 1450 PSI is enough. However, when you need to remove embedded dirt, utilize the intense pressure of 2030 PSI, and get speckless surfaces within minutes! 


We used this electric pressure washer to clean gutters, siding, birdbath, plastic chairs, and whatnot! It even worked amazingly well on the concrete patio and double driveway. 

With the Sun Joe 4000 Electric Pressure Washer, you can even clean your car! While it may not do a job as well as the professionals, it is useful for quick cleaning. 

Total Stop System:

When your hands are not on the trigger, the pressure washer will not. Now it might seem like a hassle to hold the trigger down all the time, but hear me out. 

Having this system saves the energy of your Sun Joe SPX4000. Not only that, but it also helps in prolonging the pump life so that you do not have to stop cleaning your surfaces ever! 

Ample Space in Detergent Tank:

Featuring a 54.1 fluid ounce detergent tank, the Sun Joe 14.5Amp Electric Pressure Washer, can accommodate enough detergent in it.

I found this space good enough to give the tank a cleaning boost! Any more than this would simply be a waste of detergent since the majority of performance lies with the pressure. 

Quick-Connect Spray Tips:

The 0,10,25,40 and soap spray tips give you complete control over the spraying. You can switch from a light cleaning job to an intense one with a shift of the sprays! This is especially handy when you are washing various surfaces at once. 

Ease of Use:

The Sun Joe SPX4000 1.5 Amp Pressure Washer might look bulky, but it is not! The weight of only 27.8 lbs makes moving this effortless. Nevertheless, it is still firm on its feet and does not tip over!

Other than that, it does not take much work to put it together. You do not need any tools and only need to follow the instruction manual to assemble it in under five minutes!

In Case It is Not for You
