Our review of the AR Blue Clean AR390SS corded-electric pressure washer

Our rating: 9.7
Price: Average

The AR Blue Clean AR390SS is an electric pressure washer that is advertised for medium – heavy duty outdoor cleaning. It’s the most powerful of the S line of AR Blue Clean washers. However, we’d recommend it more for light to medium-duty tasks, as it can struggle with heavy-duty grime. This is common for electric washers.

While they lack the power of gas washers, electric units like the AR390SS are usually plenty powerful enough for most tasks around the home. They don’t require fuel, oil, or complicated winterizing procedures. They’re also a lot quieter than gas-powered machines, which your neighbors may appreciate.

This particular unit is advertised as being environmentally friendly as well, using 80% less water with 45% more power than a standard garden hose.

Let’s look closer at the AR390SS so you can determine if this is a good option for you.

What do you get with the AR Blue Clean AR390SS?

AR Blue Clean Side

  • 2,000 PSI
  • 1.4 GPM
  • 14 Amp 1.6 HP universal motor w/ tri-axial pump
  • 4 quick-connect nozzles (0, 25, soap and rotary/turbo)
  • 30-foot hose
  • 35-foot power cord
  • Swivel cord
  • Hose reel for storage
  • 48 oz. detergent tank
  • Automatic shut-off
  • 1-year “bumper-to-bumper” warranty

The connections have all been upgraded from plastic to metal fittings, which is an improvement. Unfortunately, the hose reel itself is made of plastic. It’s supposed to turn to roll up the hose easily, but can be very stiff.

For some owners, it worked fine. For others, it was very difficult to turn and broke within a few uses. The hose is attached to the reel, however, so simply removing the reel isn’t simple. Some customers rigged up their own hose wrap on the machine. One customer reported he removed the original mounting screw on the reel and replaced it with a machine bolt and nut, after which it worked much better.

For flimsy-feeling hose reels, try unrolling the hose completely before using so that the hose isn’t full of water, which can make it too stiff to move on the reel.

Customers advise getting the extended warranty if possible, as a lot of the problems they had occurred just after the 1-year warranty expired.

If you won’t be running your pressure washer for 3 months or more, or need to store it for the winter, you should always run a pump saver through it to keep the internal parts lubricated, keep rubber seals from drying out, protect against freezing, and prevent corrosion.

Here’s how you do it:

  1. Make sure the unit is off.
  2. Disconnect hose and spray gun.
  3. Unscrew threaded cap from pump saver bottle to break the seal, then reattach the threaded cap.
  4. Remove the black cap from the bottle.
  5. Insert the top of the pump saver bottle onto the hose adapter on the pressure washer inlet.
  6. Twist the bottle clockwise to secure it tightly in place.
  7. Turn the unit on.
  8. Squeeze the bottle to help get the liquid into the pump.
  9. Turn off the power when the pump saver liquid starts flowing from the water outlet.

Cleaning Performance

Customers have successfully used this to clean mud off a Jeep, and also for decks, lawn furniture, home exteriors, driveways, windows, grill grates, dog kennels, and general car washing. Most agree that it is not a commercial-quality machine, and was a little slower at cleaning than more powerful units, but they were happy with how it performed for the affordable price.

Several customers mentioned how quiet it was, and some commented they were able to run the machine for a few hours straight with no issues. They liked that you can adjust the amount of detergent in the spray, which is useful when you need to clean a variety of surfaces that have different levels of grime.

What’s to love about the AR Blue Clean AR390SS?


The price is just right for most homeowners. It’ll pay for itself within 1 – 2 uses compared to what you’d pay a professional cleaning service. It won’t have the power of a commercial-grade washer, but its performance is enough for most of the general light – medium duty cleaning around your home.

With the included rotary/turbo nozzle, you’ll be able to speed up cleaning for those big jobs like driveways. It’s light enough for pretty much any adult to operate. The total stop system (TTS) helps save water and prevents accidental contact with the high-powered spray. As soon as you release the trigger, the pump shuts off. It’s also nice to be able to control the amount of detergent used.

The “bumper-to-bumper” warranty is good for a year, and customer service for the most part is helpful with returns and troubleshooting tips.

Backyard Pressure Washing

What’s not-so-great about the AR Blue Clean AR390SS?


A few customers had issues with the detergent not flowing. One customer discovered that the tube connecting the detergent dispenser to the main pump was disconnected inside the machine. He was able to use an 8-inch Phillips screwdriver to remove the panel to access the tube. He reconnected the tube, replaced the panel, and then it worked fine.

Due to how tall it is, the washer can be top-heavy and can topple over, especially on an uneven surface. The holder for the spray wand can come loose and fall off when you remove the gun. You could possibly secure it with a screw or zip tie if you have that issue. Also, nozzles may fall off the onboard storage if you’re rolling the machine over bumpy ground.

The hose, while nice and long, may kink when fully unrolled and is so stiff, it won’t lie flat. The hose reel is plastic and not as durable as it should be. Other plastic parts can make the machine feel a bit flimsy. So quality control issues usually revolve around those parts failing.

For more versatility in your cleaning experience, try these optional accessories:
