We chose to test the Sun Joe SPX3000 because it's the most popular pressure washer on Amazon. We were just as impressed in our cleaning tests, where it was runner-up to the best performers. It's also easy to use, but assembling it was a chore, which kept it from scoring higher in our usability tests. We saw prices on this machine as low as $129 and as high as $149 at different times during our research, and both are above the $120 average for the models we tested.
The Sun Joe SPX3000 cleaned cars and driveways as well as the other electric pressure washers we tested, which is to say it does a great job. However, we found it wasn't as quick to remove dirt and debris as our top performers, the RYOBI RY14122 and the Craftsman CM1800. Despite this, the Sun Joe SPX3000 is the most powerful pressure washer we tested, with an outstanding 2,030 PSI maximum pressure and 1.76 GPM flow rate. While this power didn't make much of a difference in our tests, it's still noteworthy if specifications matter to you.
Using the Sun Joe SPX3000 was a mostly positive experience. The pressure gun is easy to use, though it's not as refined and pleasant to hold as the ones from RYOBI and WORX. However, it has a trigger lock, which can improve safety, though it is mainly useful for protecting the trigger from damage while in storage. Although the unit weighs 31 pounds, it has excellent wheels that make it quite portable and perfect for moving around a project site.
The Sun Joe SPX3000 stands out in terms of its included accessories. First, it comes with five nozzles, which is the best selection we found. It includes 0-degree, 15-degree, 25-degree and 40-degree nozzles as well as soap nozzle. The color-coded nozzles are easy to connect to the pressure wand and store on the back of the machine for easy access. There are also two detergent tanks on the top of the unit, so you can switch between mixtures while washing your car. However, our testers found that this Sun Joe model’s soap nozzle didn’t apply detergent as effectively as those that came with other products.
This is the second-quietest machine we tested, reaching 81 dB – substantially quieter than our test group’s 87.4 dB average. Considering how powerful this unit is, its low noise production is surprising. The 20-foot hose and 35-foot power cord are easy enough to use but aren't particularly noteworthy otherwise.
The biggest problem we had with the Sun Joe SPX3000 was putting it together – a process more tedious than with other pressure washers we tested. Assembly took about 30 minutes, and while not particularly difficult, it was still the hardest setup we encountered. We recommend following the instruction manual closely to avoid any problems. Likewise, we were disappointed that the Sun Joe SPX3000 only has a two-year warranty instead a more generous three-year warranty like RYOBI and WORX include with their power washers.
