Sun Joe SPX4000 Review: Is this Electric Pressure Washer worth it?

Selecting a good pressure washer for your home can be a challenging task, especially when most washers are pretty expensive, require gasoline, and require additional investments in the form of parts to suit the needs of your home.

However, that is simply not the case with the Sun Joe SPX4000 Power Washer. It is a smaller Power Washer that requires no gasoline to use.

Furthermore, most of the required parts which you can need for your home cleaning projects are already pre-included in the packaging, which helps you further save up on buying additional parts for your cleaning sprees.

Also, the diverse sets of features and security measures included in the machine only make it much more of a worthy power washer which seldom leaves you yearning for more.

The Power Washer is targeted at those who wish to use it in their homes to clean their cars, decking, fences, walls, and other outdoor surfaces.

The washer is inadequate for larger areas and surfaces, but will more than satiate the needs for a home cleaning project no matter how much grime needs to be removed to make your surfaces squeaking clean again.

Without further ado, let’s head into the specifications of the product along with what’s so good about it.

We’ll also be covering what the unit lacks and could improve upon, along with reviews of what other users think about it.


The Sun Joe SPX4000 is a compact sized pressure washer measuring at 37 x 18 x 22 inches and weighing merely 27.8 pounds.

While this may be larger than other pressure washers by Sun Joe, but is still quite small compared to other pressure washers on the market, especially the commercial variants.

It can dispense up to 1.76 Gallons of liquid per minute and has a controllable knob to select the amount of pressure involved which ranges form 1450 PSI to 2030 PSI for all kinds of grime.

It also uses a 14.5 amp motor and two tanks of soap with 30 fl oz capacities each.

Furthermore, the machine also features an Total Stop System which switches off the motor when the trigger isn’t being pressed and saves both the motor and any children or pets around the machine.

The machine also has a two-year long warranty with excellent customer support. That’s all about the machine.

Now as far as the entire package is concerned, it consists of five different spray nozzles which come along with the machine itself, measuring 0, 15, 25, and 40 for various pressure requirements while cleaning varying degrees of dirt and grime.

In other words, it can be gentle and it can also very, very intense.

The last spray nozzle is used to dispense soap at lower pressures which is essential for cleaning surfacing to shine without damaging them.

The package also contains an extendable wand, a 20-foot long uniform pressure hose, a power cord with GFCI protection, a garden hose connector, as well as a cleaning kit.

Not only that, the machine doesn’t require much assembly and can be used as soon as it is taken out of the packaging with minimal adjustments made to it.


  • Compact in size (Easy to store and manage.)
  • Comes with wheels.
  • Doesn’t use Gasoline, runs on Electricity.
  • Makes less noise.
  • Dynamic Pressure selection system.


  • Lightweight, but the outer is made of plastic.
  • Not an industry level pressure washer, so don’t think of using it to clean anything larger than a home.
  • Can’t be used at places where there’s no power supply.

The above pros and cons have been backed by claims, the reason why we mentioned them in a tabular form was to allow you to get a glance of them. However, if you want to know the reasons why that particular point was a pro or a con, then you should consider reading below and finding out both in detail.

User Reviews

The User Reviews for the product are mostly positive with a few of them which are not towards the positive end of the spectrum. Most users are pleased with the performance of the Sun Joe SPX4000 while there are a few who are concerned about the performance that the machine provides.

Some downgrades, if you aren’t looking for a machine powerful like this:

We’ll be adding reviews about them shortly as well. In the meantime, let’s head to over to our final verdict of the machine.


The Sun Joe SPX4000 is certainly a power washer worthy of its reputation. After all, it wasn’t the #1 best seller in the USA for no reason.

The pressure settings which the power washer offers are quite useful to focus on the preservation of your surfaces and switch over to a more intense wash when required.

That combined with the Total Stop System adds to paramount health and safety for you when using the power washer.

Finally, even the quick connect spray tips are diverse and can accomodate the cleaning needs of most households with greater ease even without tips meant for specialisation in scrubbing Decks and walls of the home.

Just to clarify, investing on those would provide better results. Just that they aren’t a complete necessity.

The only real problem with this machine is that it has a hose limited to 20 feet, which is just a little short.

However, with all the built in safety features and adjustable powers in the machine, cleaning is as easy and efficient now as it never was before.

Especially when you want to save the items you’re cleaning from getting damaged.

And to add on top of that, most of what you would need are already included in the packaging and come as a part of the deal, saving you additional investment not only in the form of Gasoline, but also in the form of additional tools and spray nozzles.

All things considered, the Sun Joe SPX4000 is a brilliant machine to own and to use, especially considering how effective it is in removing dirt and grime from surfaces that need cleaning
