Electric PW Icon Our 2020 reviews & ratings of the Best Electric Pressure Washers, plus tips & tricks to get the most out of your new best cleaning friend

Man washing the car with electric power washer

You have three choices when it comes to pressure washing your grimy outdoor surfaces: hire a professional, rent a unit, or buy one. Purchasing your own top-performing electric pressure washer can save you money down the road, especially if you’ll use it more than once or twice a year. Gas pressure washers are another option, but for most homeowners, a top-rated electric power washer will perform just as well as an average gas model.

Why Electric over Gas*? Here are the PROS:

Electric vs Gas Pressure Washers

  • Quieter
  • Cheaper
  • Smaller and lighter
  • Easier storage
  • Can be used indoors (depends on cleaning surface)

* Like all pressure washers, they can be dangerous if not used correctly. We’ll talk about safety tips that will prevent surface damage as well as injury to you, your family, pets and plants.

Best Electric Pressure Washers – Our 2020 Ratings & Reviews

1Best Value for Your Dollar
Powerful cleaning in a lightweight package for all-purpose cleaning

The Sun Joe SPX3001 is an upgrade to the SPX3000. With this one, you get 2030 PSI at 1.76 GPM for a CU score of 3,573. A 14.5-amp/1800-Watt motor provides plenty of power for most light to medium-duty tasks.

It comes with a 20-foot hose with hose reel, 35-foot power cord, 5 quick-connect nozzles, 40.6 oz. detergent tank, a 34-inch extension wand, and a 2-year full warranty.

ProsThe Good

This unit is super easy to assemble. It’s only 32 pounds, which makes it light enough to transport easily. The Total Stop System (TTS) automatically shuts off the pump when the trigger is released, which is a good safety feature and preserves the pump. The hose reel is an upgrade over the previous model.

With the 35-foot electric cord and 34-inch extension rod, you get a lot of reach for all those surfaces around your home.

ConsThe Not-So-Good

While it’s supposed to be an upgrade, the only change is the addition of the hose reel. With the reel at the top and the tall profile of the machine, it can be unstable and prone to tipping over. The axial water pump is generic and not a well-known brand.

The long power cord is nice, but the holder for it isn’t big enough to keep it out of the way when you don’t need the full cord.

Customer OpinionWhat Customers Say

Customers like how light and easy this machine is to use. They also love the automatic shutoff. They’ve successfully cleaned many surfaces, such as siding, decks, cars, grills, driveways, and more.

Several customers agree that the hose reel is difficult to turn. The machine tended to tip over while trying to reel or unreel the hose. Some mentioned the power cord holder wasn’t big or well-placed enough to keep the cord out of the way, so they ran over it.

Take a Look At These Alternative Models:
  • SPX4000-PRO
    Sun Joe SPX4000-PRO
    Price: Average

    The 1,800-Watt, 14.5-Amp motor provides 2,030 PSI at 1.76 GPM just like the SPX3001. The main difference here is the unique small design and Pressure Select controls that let you choose between low (1,450) and high (3,020) cleaning power. Also unique to this machine is the addition of a turbo quick-connect nozzle in addition to the 5 basic nozzles. There’s also a bigger 54.1 oz detergent tank that allows you to choose the amount of detergent flow. CU Score: 3,573.

  • SPX3000
    Sun Joe SPX3000
    Price: Low

    This is the earlier model that came out prior to the SPX3001, but now is available in blue, red, and black. It has the same 1,800-Watt, 14.5 Amp motor and produces up to 2030 PSI at 1.76 GPM. Two onboard detergent tanks (0.9 L) allow you to choose between the right cleaners for different projects. At only 31 pounds, it’s easy to maneuver. This one lacks a hose reel, but is less likely to tip over. CU Score: 3,573. Read more >

2Quietest Running
Powerful clean with adjustable pressure wand and water-cooled motor

The K5 Premium is the most powerful pressure washer in Karcher’s K-Series lineup. Featuring a 25-foot hose, 35-foot power cord, and water-cooled induction motor, it can tackle light, medium and some heavy-duty cleaning tasks with 2000 PSI at 1.4 GPM.

It comes with two wands, weighs 32 pounds and comes with a 2-year limited warranty featuring a rapid exchange program for free, quick replacement of the whole machine.

ProsThe Good

The water-cooled induction motor makes this machine super quiet and prolongs the life of the motor by 5X. It has a patented N-Cor pump that protects the washer from corrosion and wear, prevents leaks, and guards against freezing temps.

Instead of nozzles to keep up with, there are two wands – dirt blaster and vario (adjustable pressure). It’s lightweight and simple to set up right out of the box.

ConsThe Not-So-Good

The vertical design makes it want to fall face down. Plastic components and O-rings aren’t as durable as they could be. Once manufactured in France, they are now made in China.

The instruction manual print is pretty small, plus the diagrams aren’t clear enough to be useful. Proprietary parts mean you can only buy Karcher parts for repairs. Calling customer service can be a bit of a cat and mouse game.

Customer OpinionWhat Customers Say

Customers were happy with performance on light to medium duty jobs such as patio furniture, cars, vinyl siding, and decks. It did well on moss buildup so long as it wasn’t deeply stained.

One problem mentioned several times was that the soap didn’t dispense well (or at all) from the dispenser. For some customers, the tendency to tip over damaged the quick connect for the hose. Some thought the pressure wasn’t strong enough.

Take a Look At These Alternative Models:
  • Karcher K2000
    Karcher K2000
    Price: High

    The K2000 delivers 2,000 PSI at 1.3 GPM. A few unique differences from the K5 are the on/off foot pedal and a storage bin for holding the spray gun or other accessories. It also includes 5 quick-connect nozzles and has a foldable handle for more compact storage. It’s a bit heavier at 44.5 pounds, but it’s also a wider, stockier machine with dual ½ gallon detergent tanks and a pressurized hose reel. This one also has a longer warranty of 3 years. CU Score: 2,600.

3The Heavy Hitter
Powerful and affordable with generous reach and adjustable soap dispenser

The AR390SS is the most powerful electric pressure washer from the AR Blue Clean brand. It has a max 2000 PSI at 1.4 GPM, a 30-foot hose, 35-foot power cord, and weighs 31 pounds.

Powered by a 14 Amp, 1.6 HP universal motor, this cleaner includes 4 nozzles (0, 25, soap and rotary/turbo) and is good for most light to moderate cleaning. It has a 1-year “bumper-to-bumper” warranty.

ProsThe Good

This is a really quiet machine for its size and output. The 30-foot hose is generous and allows for a greater reach than most machines. The included rotating nozzle works pretty well for accumulated dirt/grime.

It comes mostly assembled, so setup is quick and easy. One nice feature is an adjustable detergent dispenser to control the flow of soap so it’s not used too quickly.

ConsThe Not-So-Good

Onboard storage for nozzles is a bit unstable, so nozzles may fall off as you’re rolling it. The 1-year warranty is short but it does cover everything included in the box.

The hose reel is a bit too flimsy for such a stiff hose. There’s a tipping tendency, plus the hose tends to kink. Pressure with the soap nozzle is fairly low compared to other machines.

Customer OpinionWhat Customers Say

Several customers were happy with how quiet this one is, especially from a distance. Many commented on how easy the nozzles are to change. Customer service has been attentive and excellent with most issues.

By far, the biggest complaint was the weak cord reel, which can bend and break easily. The hose is also a sore point, with many saying it kinks too often and won’t lay flat.

Take a Look At These Alternative Models:
  • AR Blue Clean AR383
    AR Blue Clean AR383
    Price: Low

    The AR383 is a light to medium duty cleaning machine that can tackle most cleaning jobs around the house. It’s a little less powerful than the AR390SS, but with 1900 PSI at 1.5 GPM, it’s still packs a wallop for the average homeowner. The 120V, 11 Amp motor drives the 3 axial-piston wobble-plate pump and is surprisingly quiet. It doesn’t have as much of a reach as the AR390SS. It comes with a 30-foot cord and 20-foot hose. But it’s considerably lighter at only 27 pounds. CU Score: 2,850.

More Info

4Most Versatile Usage & Storage
Versatile storage and portability is perfect for small spaces

The Stanley SLP2050, as its name implies, delivers up to 2050 PSI at 1.4 GPM. It’s the latest of 5 washers in the Stanley S line and has a unique modular design for more storage and usage options.

It comes with a 25-foot soft flexible hose, 35-foot cable, 5 nozzles (0, 15, 25, soap & turbo/rotary), a 28-oz. detergent tank, and weighs 36 pounds. This washer is covered by a 2-year limited manufacturer’s warranty.

ProsThe Good

The most unique thing about this washer is that you can take it apart to use as a wall-mounted pressure washer in the garage, as a small portable unit, or on the roll cart. Wall-mounted storage also saves much-needed floor space in small spaces.

This washer is water-efficient as well, saving up to 80% over a standard garden hose with 40% more pressure. Professional-grade brass hose connections are sturdy and durable.

ConsThe Not-So-Good

If you’re looking for heavy-duty or commercial-grade cleaning, this isn’t the machine for you. While it’s great for most light – medium duty tasks, it won’t hold up well to hours of daily use. Overuse could result in leaks or a worn out pump.

There is some confusion in that Annovi Reverberi (AR) actually manufactures these Stanley machines, and at least one customer got an AR Blue Clean washer instead.

Customer OpinionWhat Customers Say

Customers like how light and versatile this washer is. Also, customer service is usually very responsive and will gladly help troubleshoot problems over the phone. They’ll also replace any parts under their 2-year warranty, no matter where it’s bought.

Some customers thought there were missing nozzles, but they are actually already onboard in their holder when you unbox the item. Just unwind the power cord from the top of the machine to find them.

Take a Look At These Alternative Models:
  • Stanley SHP2150
    Stanley SHP2150
    Price: Low

    The SHP2150 is a step up in cleaning power from the SLP2050. With 2,150 PSI at 1.4 GPM, this washer can tackle most medium-duty and some heavy-duty jobs around the home. It’s lighter than the SLP2050 at only 26 pounds, but has the same hose and cord length. The 28-oz. detergent tank also doubles as a foam cannon. This washer has 4 quick-connect nozzles (0, 15, 25, & 40) but lacks a turbo/rotary nozzle. It also doesn’t have a hose reel. CU Score: 3,010.

More Info

5Electric Power Washer
Sturdy steel frame and foldable handle for a durable, compact machine

The 20680 is another storage-friendly washer with a foldable design for storing under shelves or workbenches. It’s best for light-duty tasks and produces up to 1,800 PSI at 1.2 GPM. A 20-foot hose offers good reach.

It comes with 3 quick-connect nozzles (15, turbo/rotary, & soap) and a ½ gallon detergent tank. It weighs 31.5 pounds. The 1-year full warranty covers all included parts and accessories.

ProsThe Good

A welded steel frame gives this washer a commercial-grade feel. The wide base prevents tipping. Plus, it’s not top-heavy like some washers. It thoroughly tackles light-duty jobs like patio furniture, car washing, walkway cleaning, etc.

The handle folds down to make it compact for storage, which is great for small, crowded garages. The included turbo nozzle cuts cleaning time by 40%.

ConsThe Not-So-Good

Again, this is not meant for heavy-duty all day use. It’ll be fine for a few hours on the weekend to wash the car, the patio furniture, etc. If you want to use a different hose or any other nozzles or accessories not included in the box, just know these aren’t covered under the warranty.

Hose connections are really close to the frame, so if you have large hands, it’s hard to attach/detach the hoses.

Customer OpinionWhat Customers Say

Customers have been impressed with the performance of this machine. Though it’s not really meant for whole-house siding cleaning, some customers have cleaned a portion of their siding and were pleased with the results.

Customer service isn’t as responsive as other manufacturers. Some customers said they unboxed the unit to find water in the hose, which could mean they received a returned unit.

6Electric Power Washer
Light to medium-duty power with self-suctioning feature & extra wand

Powerful and lightweight at only 25 pounds, this pressure washer produces 2200 PSI at 1.8 GPM with a 14.5 Amp, 1,600 Watt motor. Included are 5 nozzles (0, 5, 25, 40, & soap) and bonus turbo wand with high pressure and wide stream.

Great for most light & medium-duty cleaning, it has a 20-foot hose and 35-foot power cord and comes with a 1-year warranty.

ProsThe Good

Onboard storage for wands and nozzles helps keep all accessories in one place. A Total Stop System (TSS) shuts the machine off automatically when you release the trigger. Brass nozzle connectors are sturdy and easy to use.

One of the most unique features is a self-suctioning feature which can pump water from a stationary source such as a bucket or tank. Setup is simple, and the instruction manual is easy to follow.

ConsThe Not-So-Good

The 20-foot hose isn’t as generous as some other brands. The handle and wand are a bit flimsy, so are prone to leaks and breakage after a few uses. Location of the hose makes it easy to roll over it when moving the machine.

The hoses and power cords can get tangled around each other. In hot conditions, the motor is more prone to overheating. It’s also not the quietest pressure washer you’ll find.

Customer OpinionWhat Customers Say

Customers who have well water reported good performance, even on long-neglected decks. They love the automatic shutoff. It worked well on various surfaces such as cement, stucco, and wooden decks.

The most common complaint involved the handle/wand. Several people reported that it busted or sprung a leak after a few uses or just after the warranty expired. It’s also louder than some customers would have liked.

7Lightest to Maneuver
A super lightweight washer great for those with mobility issues

If you’re looking for compact and light, the Greenworks 1600 PSI is just right. This little portable washer has a 13 Amp motor that produces up to 1600 PSI at 1.2 GPM. It’s very affordable and designed for light-duty cleaning.

This unit comes with a 20-foot hose, 35-foot power cord, and 3 nozzles (25, 40, & soap applicator). It weighs only 17.5 pounds and is covered by a 1-year warranty.

ProsThe Good

This is a very affordable machine. You can use it either vertically or horizontally. It has no wheels, but it doesn’t need them since it’s so lightweight and easy to carry. People with less upper-body strength should have no issues moving this washer around.

Instead of always having an onboard detergent tank, the soap applicator serves as a removable tank, which decreases the weight even more when you’re not using it.

ConsThe Not-So-Good

You’re getting a pretty basic package with this machine. There’s no hose reel or wheels and only 3 nozzles. All the parts are plastic, so you can’t treat this like a heavy-duty machine. You may have to apply detergent and let it sit to get the best results.

Larger jobs are going to require a lot more time with this machine. Be sure to store it inside over the winter so temperature changes won’t affect the seals.

Customer OpinionWhat Customers Say

For light-duty tasks, customers were mostly pleased with this machine. It cleans light grime and may take a little pretreating for tougher stains. It’s probably best for first-time pressure washer users, also for the elderly or those with less upper-body strength or mobility issues.

Customer service can be hit or miss when you try to contact them. A few customers have received returned units.

Take a Look At These Alternative Models:
  • Greenworks GPW1950
    Greenworks GPW1950
    Price: Average

    For a power boost over the Greenworks 1600, the Greenworks 1950 may be just what you need for light to medium duty tasks. The 13-Amp induction motor produces up to 1950 PSI at 1.2 GPM. It comes on a two-wheeled frame and has a longer reach with the 25-foot hose and 35-foot power cord. Four nozzles are included (0, 25, 40, &amp soap). It has a fold-down handle and dual onboard detergent tanks. The hose reel is recessed in the top to make it even more compact. CU score: 2,340.

More Info

Ah the joys of owning your own pressure washer. For most homeowners, electric models like the ones we listed here are plenty powerful enough for your average cleaning tasks. If you need something that will tackle really heavy-duty tasks like paint stripping, deep stain removal, etc. you should probably consider a gas pressure washer. We have a few suggestions for those too.

Play it safe with pressure washers

Safety is a big concern with any pressure washer. Some people don’t understand that pressure washers can be dangerous. The very high pressure produced from the water stream can seriously injure people and some surfaces like car paint or glass. We’re talking skin lacerations, even amputations, plus kickback forces that can easily knock a person off a ladder.

Be very careful operating pressure washer on a ladder or, better yet, do not do this at all.

Pressure washers are a godsend for exterior cleaning, but you have to respect them. To stay safe, be sure to check out our beginner’s guide to using pressure washers safely.

Here are some basic safety tips for electric pressure washers:

    Gfci socket.
  1. Read and follow the manual!
  2. Wear protective clothing – long pants, goggles, work boots or other sturdy closed-toed footwear
  3. Start spraying surfaces about 2 feet away and gradually move closer, no closer than 6 inches
  4. Stay off ladders!
  5. Never EVER point the nozzle at any part of you, other people, pets, or plants
  6. Do NOT use extension cords for electric pressure washers
  7. Always plug into a GFCI outlet

Nozzles and other attachments

Power Washers Nozzles

Most pressure washers come with interchangeable nozzles that allow varying widths of water streams.

The typical types are:

  • red (0 degree)
  • yellow (15 degree)
  • green (25 degree)
  • white (40 degree)
  • black (soap)

According to Consumer Reports, as soon as you open the box, you should TOSS the red (0 degree nozzle). It’s the highest pressure nozzle and shoots a very narrow stream of water, which makes it capable of serious physical injury and property damage. You will rarely, if ever, have a cleaning job that requires a 0 degree nozzle. Just pretend it was never there…

There are other attachments and accessories you may find helpful for your pressure washer. Some of these you have to buy from the washer’s manufacturer, while some are universal. Here are a few:

  • Surface cleaner
    Surface cleaner
    Spinning bar that delivers water stream over a big surface area. Good for large areas like a driveway.
  • Rotary nozzle
    Rotary nozzle
    Sometimes called a turbo nozzle, sometimes included as a bonus nozzle in the box. Produces a spinning narrow water spray. Good for stubborn stains and grime buildup.
  • Pressure washing broom
    Pressure washing broom
    Like the surface cleaner, splits single jet into two or three for cleaning large areas. Good for car or boat washing.
  • Wand extension
    Wand extension
    Helps you reach high areas so you don’t need a ladder.
  • Hose extension
    Hose extension
    For cleaners with shorter (20 ft or less) hoses, you may want a hose extension. Though this could lessen the pressure somewhat, it’s better than putting yourself in a dangerous position to reach an area for cleaning.

Troubleshooting Tips & Tricks

How to fix electric pressure washer

During our research, we came across customer and manufacturer suggestions for fixing various issues that may arise with a pressure washer. With electric models, the most common complaints involve the motor not starting and pressure loss. If you’re not confident with your fix-it skills, take your machine to a local repairman or call the manufacturer to see about a replacement. But for those fix-it folks among you, try these tricks.

For motors that no longer start:

  1. Check the reset button on the plug. It’s possible to trip it while plugging it into the power outlet outside.
  2. Try a pump protector lubricant after each use, like this one from Briggs & Stratton. Leftover water in the unit can seize up the pump’s internal gaskets. You screw the plastic threads on the lubricant bottle into the threaded garden hose inlet on the pressure washer and squeeze the trigger on the bottle. It’s especially good for use before extended storage (winter, for instance) and before first startup the next season.
  3. Check the GFCI plug first and replace if needed.
  4. There could be an electrical issue within the GFCI plug of the power washer itself, especially if it’s left out in the rain or where there’s lots of humidity. With the unit unplugged, use a screwdriver to take the cover off of the cleaner’s GFCI plug. If you see lots of moisture trapped in the plug, that can prevent it from running. You can buy a replacement plug at the hardware store or one like this Leviton brand online. Just reconnect the wires to the new GFCI plug (black wire to gold connector, white to silver) and turn the screws to secure the wires. Screw down the “U” shaped stress clamps that come with the new plug. Then attach the new cover, and try starting up the machine.

For pressure loss:

  1. The nozzle may have a blockage. Turn the pressure washer off, and bleed air out of the system. Remove the nozzle. Hold the nozzle by the sides with the front of the nozzle facing you. Using the spray tip cleaning tool or a straightened paper clip, try pushing the clog back the way it came. Rinse the nozzle thoroughly front and back. Replace the nozzle and try washing with it again. If the nozzle remains clogged, remove it and repeat the process. If still clogged, try soaking the nozzle in hot water and then try washing again.
  2. Air in the hose may be the source of the pulsating pressure.
  3. Try a different nozzle – you might not be using the right one.
  4. Look to see if the hoses are kinked and straighten them out.
  5. Check the inlet and un-loader valves. If clogged, clean them or replace with new valves.
  6. For pulsating pressure, turn off the machine and try bleeding air from the hose by squeezing the trigger.


Still having trouble? Try looking up troubleshooting videos like this one about troubleshooting a Karcher pressure washer. If all else fails, call the manufacturer if your warranty is still in effect to see if they can help. If your warranty has expired, you’ll probably just have to purchase a new one.

I’m looking at the Bauer 2000psi electric unit. It has a 4.8 star rating. Any comments?

February 11, 2020 at 10:08 pm

My parents are retired and not in the best of health. But they want a pressure washer to keep their walk and deck clean. What is better for them- the Sun Joe SPX3001 or AR Blue Clean AR390SS?

Kevin (Cleanup.Expert Team)
February 13, 2020 at 4:12 am

For older people or those with mobility issues, the AR Blue Clean probably has the advantage over the Sun Joe. It’s pretty lightweight at only 31 pounds and breaks down for compact storage when not needed.

It’s good for most light-moderate duty jobs around the home, which should meet their needs just fine unless there’s a heavy grime buildup. It comes with a rotary/turbo nozzle for the tougher dirt which won’t require as much time and physical effort. Due to its height, it can be a little top-heavy and prone to tip over if not kept level. But the total stop system automatically shuts off the spray when the trigger is released, which is a good safety measure in case the wand is dropped.

What do you think of the Sun Joe spx3501? Choosing between this and spx3001. Thanks for the help.

Kevin (Cleanup.Expert Team)
December 3, 2019 at 11:34 am

The SPX 3501 is a step up from the 3001 in price and additional power. The 3501 produces up to 2300 PSI at 1.48 GPM while the 3001 produces 2030 PSI at 1.76 GPM.

You do have a sturdier body style on the 3501 – wider on the bottom than the top, which may prevent the problems the 3001 has had with flipping over during use. The 3501 may be a little quieter at higher speeds with its brushless induction motor.

Other than that, they have the same specs in terms of cord and hose length and detergent capacity. So it’s kind of a toss up. If you want a little extra power, a steadier foundation, and don’t mind paying around $50 more, go with the 3501.

I have a lot of second story cleaning (windows/siding) to do, but I’m afraid my little light-duty Greenworks washer won’t cut it. What PSI do I need my pressure washer to have?

James (Cleanup.Expert Team)
September 16, 2019 at 10:49 am

Any kind of second-story work will take at least a mid – heavy duty pressure washer up to around 3000 PSI. The reason being, you’ll likely need a hose or wand extension, and adding extra length means lowering the pressure.

Since the Greenworks rings in at about 1600, you’ll definitely want more oomph. If you prefer an electric power washer, we’d recommend the AR Blue Clean AR390SS or the Karcher K5 Premium or Karcher K2000.

I have access to both hot and cold water in my garage. For killing mildew and bacteria, I’d prefer to pressure wash with hot water, but can I use hot water in my pressure washer or not?

James (Cleanup.Expert Team)
September 12, 2019 at 5:16 pm

That depends on the pressure washer. There are pressure washers specifically designed for use with hot water or those that heat the water for you post-pump. For most models, though, the answer is no.

Hot water can damage pressure washers for a couple reasons. One, the seals around the pump and tubing could be damaged with water that’s over 100 degrees F. Also, your water pump depends on the water flow to help keep it cool. You risk overheating it if you run hot water through it.
