Pressure washers are some of the best – not to mention some of the most fun – tools to use. Using a pressure washer makes easy work of washing your cars and outdoor furniture. After owning and using a high-power pressure washer, you’ll wonder how you made it through life without one. The days of dragging around long garden hoses with inadequate washing power are over.

Sun Joe has specialized in producing outdoor and gardening tools since 2004. Their first product – a budget-friendly electric snow shovel dubbed Snow Joe – swept competitors away, and since then they’ve made a huge impact on outdoor tools. Their line of electric-powered pressure washers follows the company’s promise of affordable, top-notch tools.
In this article, we’re going to pay close attention to three of Sun Joe’s pressure washers which pressure-wash competitors away: the SPX3000, SPX4000, and SPX4001. Without further ado, let’s see what these three models have in store.
Motor and Power
SPX3000, SPX4000, and SPX4001
The heart of a pressure washer lies on how much power the machine’s motor can deliver. Across the board, we see that they feature 14.5 amp motors and 1,800 volts. All three models also provide up to 2,030 PSI and 1.76 GPM. The high PSI and relatively low GPM result in more efficient blasts of water, effectively reducing water use. They are far from being the most powerful motors mounted into home-use pressure washers, but they provide sufficient strength in cleaning all sorts of outdoor messes.
5 Quick-Connect Nozzle Spray
SPX3000, SPX4000, and SPX4001
Once again, there’s no difference in nozzles between each of these units. They each come with a 0°-nozzle for super concentrated blasts of water for lifting caked-on grime, a 15°-nozzle for slightly less concentrated but still powerful streams of water at a wider area, a 25°-nozzle for cleaning sidewalks and driveways of dirt and oil spills, a 40°-nozzle which shoots the least concentrated flow of water for use against gentle surfaces and windows, and a detergent nozzle for shooting bubbles from each of these unit’s built-in detergent tanks.
Detergent Tank
SPX3000
This unit comes with two separate detergent tanks, each with a capacity of 30 fl oz of soap. The separate tanks are for pouring soaps of different viscosity detergent for different cleaning tasks. For example, depending on the stain on your car’s body, you’ll need watered-down soap to not strip the paint and a thick concentration of soap for deeper cleaning.
SPX4000 and SP4001
These two electric pressure washer models feature a single built-in 54.1 fl oz detergent tanks. You don’t have the option to separate soaps based on thickness or purpose, but in most cases, it’s not a problem. Unless you’re planning on opening your own professional car was, a single tank for all types of soaps is sufficient.
Weight
SPX3000
All three Sun Joe pressure washers here are relatively lightweight and easy to maneuver. Its portability is mainly attributed to their easy-glide wheels. The Sun Joe SPX3000 weighs around 31 pounds after assembly.
SPX4000
This electric pressure washer weighs the least among these models, being only 27.8 pounds fully assembled. Once again, the wheels make the unit portable since you’re not going to carry it on your back.
SPX4001
This is the heaviest of the three models but the differences are insignificant. This machine weighs 32.4 pounds after being put together. If weight isn’t a consideration, then any of these products could serve you well.
Pressure Select Technology
SPX3000
The SPX3000 doesn’t come with a variable speed dial or switch, meaning that you’re stuck shooting out blasts of water at a consistently high speed (up to 2,030 PSI). One very difficult way to control water pressure is by pulling the trigger slightly and slowly. The quick-connect nozzles also help in providing wide-spread, low-pressure streams of water.
SPX4000 and SPX4001
The SPX4000 and SPX4001 feature Sun Joe-made pressure select technology. This feature allows users to control the speed and power of delivery. The low gear provides 1,450 PSI for lifting everyday dirt and grime. The high 2,030 PSI is better suited for stubborn messes like oil spills on your driveway.

Hose Reel
SPX3000 and SPX4000
There two machines don’t come with a hand-cranked hose reel. After everything’s done, the user(s) need to manually reel in the hose to eliminate sloppiness and excessive floor space when leaving the unit in storage.
SPX4001
This is the only model between the three that comes with a hose reel. Being neat and clean is important, and you want to keep the hose reeled in to avoid accidents and damage. It’s not exactly a high-tech feature but it was something we missed in the other two pressure washers.
Safety Lock Switch
SPX3000, SPX4000, and SPX4001
The best thing about these budget-friendly pressure washers is their built-in, Sun Joe-proprietary safety lock switch located on the trigger. When the machine that the trigger is not pulled, it will automatically shut the machine off, saving energy and water. It also serves to prolong the life of these pressure washers.

Accessories
SPX3000, SPX4000, and SPX4001
The good thing about these three models is that they require hoses and attachments of the same size. Each of these attachments can be used in any of the models so there’s no confusion about which attachment belongs to which unit.

What is a Good PSI for a Pressure Washer?
Bottom Line
As you can tell, there are several overlapping features between the SPX3000, SPX4000, and SPX4001.
There’s hardly any reason to select one over the other, except for the dual detergent tank system for performing different cleaning tasks without having to waste or constantly replace soap. Weight is another distinguishing factor between the three pressure washers, but it’s really insignificant in determining which one of these models is most portable.
One feature that we found extremely useful is the safety lock switches on each unit which prevents wasting water, turns off the machine when it’s not in use, and the implication that it can prolong the life of your title.
Finally, in terms of the hose reel, it’s a handy feature that the company missed when designing the SPX3000 and the SP4001. It’s not a deal breaker but it can be a nuisance when needing to store the machine in your home.
