How to Find the Best Power Washer for Your Needs

Pressure washers are used for a wide variety of tasks around the home, the workshop, the farm or on commercial jobs. Choosing the correct power washer is mostly a matter of matching the work to the correct water pressure range. The amount of pressure as measured by PSI and the flow rate measured as GPM are the best indicators of the type of job for which the pressure washer is designed. The best pressure washers allow varying PSI and GPM to match output to a particular job.

Light-duty Pressure Washers

This class of power washer produce 1500 to 1900 PSI of water pressure. These are economical and the best pressure washers for most home cleaning tasks:

  • Removing mold, mildew and dirt from driveways, sidewalks, decks, siding and eaves
  • Refreshing the surface of brick, tile or stone facades
  • Cleaning your car’s or boat’s exterior
  • Washing patio furniture, garbage cans, bikes and other toys

AR Blue Clean AR390SS Cold Water Electric Pressure Washer 2000 PSIThe best value in a power washer at this level is the AR Blue Clean AR383SS 1900 PSI Cold Water Electric Pressure Washer. Its 13A of power puts out 1900 PSI. The 30-foot hose reaches all around a pickup. The cord storage, hose reel and wand holster make storage simple and fast.

The on/off switch and hose connections are accessible on the front. It comes with a fan spray nozzle, pencil spray, low pressure detergent nozzle and a turbo nozzle for the toughest grime-removal jobs. No wonder it is the top-selling home power washer in North America.

Medium-duty Power Washers

This power range puts out 2000 to 2800 PSI. This size of water blaster performs all the jobs that a light-duty machine can but faster:

  • Cleaning your car’s or truck’s chassis
  • Removing grease from engines or transmissions
  • Cleaning BBQ grills during or at the end of a season
  • Blasting out dried grass clippings under your mower

YardForce YF2200BL Electric Brushless Pressure Washer 2200 PSIUsually, this pressure range requires power from gasoline engines. The best pressure washer for car cleaning is in this category: the YardForce YF2200BL Electric Brushless Pressure Washer. This electric washer puts out 2200 PSI and 1.25 GPM and four digitally-controlled pressure settings to exactly match the application.

It comes with five sprayer tips, including a soap tip. We love the super-flexible 25-foot wand hose and the roll-cage cart with 12-inch wheels. This is one of the most portable, most versatile, most powerful medium-duty washers. At under $350, it is also a superb value.

Heavy-duty Water Blasters

Pressure washer in useThis level of pressure washer outputs 2900 to 3200 PSI plus ample GPM for blasting the toughest dirt, grease and grime. They do everything the medium-duty washers do, but more efficiently. They make quick work of preparing the exterior of a home for painting.

In our opinion the Simpson PS3228-S PowerShot 3200 PSI 2.8 GPM blaster is the best power washer in this class. It has a lot of pro features such as a commercial-grade Honda GX200 OHV engine with Oil Alert, a poly-braided, kink-resistant hose, and a welded steel frame with pneumatic tires.

The triplex plunger pump features ceramic-coated pistons and Simpson’s PowerBoost technology that results in high-impact, crud-blasting 3200 PSI and super-efficient 2.8 GPM water flow. Five pro-style quick-connect nozzle tips are included: 0, 15, 25 and 40 degree spray plus a soap applicator. For absolutely any home or workshop application or even a small pressure washing service, this machine delivers.

Commercial-grade Pressure Washers

These are the most powerful pressure washers you can buy. They produce 3300 PSI and above and plenty of GPM. They feature commercial-grade engines and durable components to withstand daily use through the toughest cleaning jobs:

  • Cleaning roofs and siding on large metal buildings
  • Cleaning parking lots of crud, debris, oil and grease
  • Washing down livestock barns and trucks
  • Blasting off rust and dried concrete from trucks or construction equipment

Pressure Pro E4040HC Heavy Duty Professional 4,000 PSI 4.0 GPM Honda Gas Powered Pressure Washer With CAT Pump (CARB Compliant)In this top class, perhaps the best commercial pressure washer is the Pressure Pro E4040HC Heavy Duty Professional 4,000 PSI 4.0 GPM Gas Powered Pressure Washer With CAT Pump. This “Cadillac” grade power washer outputs 4000 PSI and 4.0 GPM, which will blast through the dirtiest jobs. The 13-HP Honda engine has push-button electric start. The ceramic-piston CAT pump and belt drive mean cooler pump operation. Both engine and pump have overheat protection.

Spray pressure is adjusted with a single knob. The aircraft-grade welded aluminum frame and big pneumatic tires make this washer highly mobile even up and down stairs. This is an ideal washer for a small cleaning company as it has a chemical injector hose and can handle up to 180F water at the inlet. Incredibly, the price on this professional-grade blaster is under $1400.

Our Top Recommendation for a Pressure Washer

If you are a homeowner who only uses a power washer a few times a year strictly for light-duty tasks the Simpson PS3228-S PowerShot 3200 PSI 2.8 GPM Honda GX200 Engine Gas Pressure Washer is probably overkill. But if you want a top rated pressure washer that performs superbly on tenacious dirt and stains, this is your machine. At under $550 it is a bargain considering its power.

Who Makes the Best Pressure Washer?

This is somewhat like asking who makes the best pizza, since everyone has their own tastes. However, there are some clear leaders among power washing equipment makers:

Quality Economical Manufacturers

  • Annovi Reverberi or AR has been building power washers for 50 years. Their latest products are innovative and affordable, such as their hand-held AR Blue Clean AR118 1,500 PSI 1.5 GPM Electric Pressure Washer that sells for under $100.
  • Campbell Hausfeld has a full line of power washers from economical models such as the 1900 PSI PW183501AV Electric Pressure Washer up to commercial-grade machines.
  • Karcher has been making pressure washers since 1950. They feature budget-washers and a powerful Professional line. In the middle is their X-Series such as the Karcher K 5.540 X-Series 2000PSI 1.4GPM Electric Pressure Washer, which is a top-rated home use power blaster.
  • Other residential power washer brands that deserve mention are Briggs and Stratton, Greenworks, Sun Joe, WEN, and Powerworks.

Higher-End Power Washer Manufacturers

  • Pressure-Pro makes over a hundred pressure washers from under $600 up to 7000 PSI monsters that cost around $6,000. We gave you a sneak peak at their affordable Pressure Pro E4040HC, but another model we recommend is their more affordable E3027HC Heavy Duty Professional 2,700 PSI 3.0 GPM model. All Pressure Pro blasters are built to handle commercial conditions.
  • Simpson has been around since the 1960s. They produce residential and commercial lines. Even their lower-end products, such as the Simpson ALH3228-S Aluminum 2.8 GPM Gas Pressure Washer are durable, powerful and easy to operate.
  • BE is an oft-overlooked Canadian manufacturer that makes a full line of quality hot/cold, electric and gas-powered pressure washers for residential and commercial markets. In the latter area, the BE Pressure PE-4013HWPACOMZ Gas Powered Pressure Washer, GX390, 4000PSI, 4 GPM is a powerful, fully-featured commercial washer that stands up against the best power washers available.
  • Other good quality commercial-grade manufacturers include Easy-Kleen, DeWalt, Generac, Cam-Spray, Shark, Northstar, Mi-T-M and Rigid.

Our Top-Rated Power and Pressure Washers – Ratings and Reviews

Here are six more power washer reviews for models we can highly recommend in the electric and gas-powered categories. In each category, we have selected a range of models for light-duty to heavy-duty tasks.

Best Electric Pressure Washer Reviews

Sun Joe SPX3000 2030 PSI 1.76 GPM Electric Pressure Washer

Sun Joe SPX3000The SPX3000’s 2000+ PSI and nearly 2 GPM water flow makes short work of deck and patio grime, siding and eave mildew and keeping the car, boat, RV and outdoor furniture sparkling. It has a dual detergent tank system and five different spray nozzles. The Total System Stop trigger automatically shuts down the pump when the wand trigger is disengaged to prolong pump life. A 35-foot heavy-duty cord and 20-foot pressure hose are included.


  • 2000 PSI and five nozzles spell power and versatility
  • Dual detergent tanks
  • TSS switch-off adds years to pump life

  • Wish the pressure hose was five feet longer

magnifying-glass-189254_1280Review and Rating

While the Sun Joe SPX3000 provides a bit more oomph at 2030 PSI/1.76 GPM than the Karcher K 3.000. It is a conventional vertical design, but the larger than average wheels provide ample portability even on uneven surfaces.

The built-in dual soap/degreaser tanks are very handy. If one soap is not working, flip a dial and blast it with a more powerful mixture. Leaving a power washer pump idling with no water flow creates internal pump heat, so the automatic trigger shutdown adds years to pump life.


Buyer’s Sun Joe pressure washer reviews are nearly unanimous in finding this blaster to be just what they need for light-duty tasks all over the house, yard and shop. For its plentiful power, flow, easy-rolling portability, dual soap tanks and the TSS automatic switch-off, we can definitely recommend this as an excellent value under $150.

AR Blue Clean AR390SS Cold Water Electric Pressure Washer 2000 PSI

AR Blue Clean AR390SS Cold Water Electric Pressure Washer 2000 PSIAR Blue is the new green, with 80 percent less water used than a typical hose sprayer for the same cleaning work. The AR390SS stands up to any residential cleaning demand. The 14A electric motor outputs 2000 PSI at 1.4 GPM. The nickel spray wand is a quick-connect style that takes three different nozzles for 0, 25 and 55 degree spray widths plus a soap applicator tip, which draws on a built-in detergent tank.

A turbo nozzle blasts away tough stains or stuck-on crud. Storage is a snap with hooks for the spray wand and 35-foot power cord plus a convenient hose reel. The power cord comes with a built-in GFCI so you can use this power washer from any outlet.


  • 2000 PSI/1.4 GPM is powerful enough for all residential cleaning
  • Three nozzles plus soap tip for pressure and width control
  • On-board detergent tank
  • A turbo nozzle is included

  • Needs a 15-degree nozzle

magnifying-glass-189254_1280Review and Rating

If you have surveyed as many AR power washer reviews as we have, you know this is a very popular residential-grade electric power washer. The highly flexible hose, nickel gun, wand and tip assembly and real brass couplings are usually found on more expensive gas models.

We loved how quiet and vibration-free the AR 390SS is when spraying. The turbo nozzle blasts off the stickiest mud and light layers of dried concrete or rust. It is safe for paint prep as it will not tear up aluminum or wood material. For just over 200 bucks, it is a bargain considering the build quality and the extra oomph of 2000 PSI.


AR Blue’s innovative designs and quality components are making a big splash and the 390SS is a perfect example of that. The reviews from buyers are overwhelmingly positive about the capabilities and ease-of-operation this pressure washer provides. You will be impressed how quietly and efficiently this high-value machine handles your cleaning tasks.

Karcher K 3.000 Follow Me 1800PSI 1.3GPM Electric Pressure Washer

Karcher K 3.000 Follow MeThe Karcher K 3.000 front-caster, four-wheel design means no more tipping over the pump/power unit when you have extended the pressure hose to its full-length. Instead, the K 3.000 follows you wherever you go.

The 1800 PSI/1.3 GPM capacity is plenty for light-duty jobs around the home including driveways, patios, fences, lawn furniture or washing the car. All connections are quick-connects so there are no threads to fuss with. It has an on-board detergent tank and Vario pressure wand from which you can choose high-pressure cleaning or low-pressure soap application with a twist of the nozzle.

Also included is a DirtBlaster turbo wand for digging out the most stubborn stains, mildew and mud.


  • Super-portable with four wheels and weighing just 16 lbs.
  • Variable wand matches spray pattern to any task
  • DirtBlaster wand cleans out cracks and blasts off stubborn crud
  • Lots of accessories available for common cleaning tasks

  • Cord and hose management could be better

magnifying-glass-189254_1280Review and Rating

There should be more pressure washers copying this low-profile, pull-along design as it is very handy. The many glowing Karcher pressure washer reviews for this and other models demonstrate how well the Karcher brand is considered.

This may not be the best electric power washer ever made but it comes close and the price is phenomenal. We had no problem blasting off years of sticky grime from a concrete sidewalk, and the turbo wand scours out cracks and knocks off caked-on mud well. For a light-duty machine, the Karcher does it all and the four-wheel design is a big plus.


If you are a suburban homeowner with an average yard who is looking for the best electric pressure washer at a budget price, look no further than the K 3.000 from Karcher. Its unique 4-wheel, low-profile design makes this the most portable, budget machine available. You will love how well it cleans, and how easy it is to use and store.

Best Gas Pressure Washer Reviews

Generac 6590 3,100 PSI 2.8 GPM 212cc OHV Gas Powered Commercial Pressure Washer

Generac 6590 3,100 PSI 2.8 GPM 212cc OHV Gas Powered Commercial Pressure WasherThe 6590 pressure washer continues the tradition of powerful, well-built machines in Generac’s power equipment catalog. Its 6.5-HP, 212cc OHV engine and a powerful triplex plunger pump combine to produce 3100 PSI and 2.8 GPM of water flow. That is cleaning power enough for removing grease stains from concrete, stripping paint, cleaning truck chassis and scouring out livestock pens with ease.

The pump has an adjustable pressure regulator for tuning PSI/GPM to the job at hand. Five quick-connect nozzle tips match any task with 0, 15, 25 and 40 degree patterns plus a soap applicator with on-board detergent tank.

The 6590 has better reach than most power washers in its class with a 35-foot pressure hose. Everything is mounted to a sturdy, welded steel frame and it all comes with Generac’s generous 3-year warranty.


  • 3100 PSI/2.8 GPM semi-pro machine
  • On-board pressure adjustment
  • Five nozzles including soap applicator
  • On-board detergent tank

  • Non-pneumatic tires are rough on uneven terrain

magnifying-glass-189254_1280Review and Rating

This is a durable power blaster for users who desire uncompromised power that most residential machines cannot provide. This machine faces down any cleaning chore around the house, shop or barn. You will never be wishing it could do more. For those more delicate jobs, like washing the car, simply dial down the pressure regulator.

We tested this machine by removing grime and algae off the siding of a two-story house. Thanks to the long pressure hose we only had to move the machine once. The widest nozzle blasted off the crud in a single pass, so we finished in about an hour.

Generac pressure washer reviews back up our experience. The hard tires are not so easy to roll over bumpy yards as pneumatics. This machine got an extra half star because the price was recently reduced to under $480, which makes it a screaming buy.


The Generac’s 6590’s power will blow away even the best electric power washer among residential-class washers. Although this machine might not survive the 3-year consumer warranty if used daily on commercial jobs, it will last a lifetime for any home, shop or ranch cleaning tasks you care to throw at it. In the under $500 class of power washers with this kind of power, it is a superb bargain.

Simpson MSH3125-S MegaShot 3100 PSI 2.5 GPM Honda GCV190 Engine Gas Pressure Washer

Simpson MSH3125-S MegaShot 3100 PSI 2.5 GPM Honda GCV190 Engine Gas Pressure WasherThis compact, powerful gas-powered power washer sports a one-pull Honda GCV190 engine that is smooth and quiet as silk. With 3100 PSI/2.5 GPM, it is a top-end residential or semi-pro machine that can tackle nearly any cleaning task you can imagine. Although priced for homeowners, it comes with many quality features besides a top-grade engine.

The lancet quick-connects to five included nozzles: 0, 15, 25, 40 degree patterns plus a soap applicator. It has a quality axial cam pump from Faip, a siphon tube for detergent and easy-to-roll pneumatic tires. The package rests on a durable welded steel frame.


  • 3100 PSI/2.5 GPM
  • Four different spray patterns plus soap applicator
  • Easy-roll pneumatic tires

  • Small-diameter, PVC pressure hose
  • No on-board detergent tank

magnifying-glass-189254_1280Review and Rating

Given the amount of power and flow this machine provides and Simpson’s reputation for building quality machines, we could not pass it up despite the lack of a couple of amenities. Frankly, we did not like the low flexibility and cheap feel of the PVC pressure hose nor the fact that it has no on-board detergent tank. Otherwise, the cleaning power is definitely there, which would put to shame less expensive electric power washers.

Buyers are well satisfied with their purchase judging by high ratings in Simpson pressure washer reviews for this model. It is clearly priced right at under $400, which is well within the budget of the average homeowner looking for maximum cleaning power.


The Simpson Megashot MSH3125-S has all the power you need at home or on the ranch and comes in a quiet, reliable, compact package that is highly portable. If you can do without an on-board soap dispenser and a stiff hose, but want no-questions-asked power from your washer, then this is a top value among the gas-powered pressure washers.

Generac 6596 2,800 PSI 2.5 GPM 196cc OHV Gas Powered Residential Pressure Washer

Generac 6596 2,800 PSI 2.5 GPM 196cc OHV Gas Powered Residential Pressure WasherThis is Generac’s consumer-grade, gas-powered power washer. Do not let the size and price fool you, however. This is a hardworking machine with ample power for cutting through slime, grime and other crud. The easy-start, 196cc Honda engine is quiet and reliable.

The high heat-dissipation axial cam pressure pump is positioned so kneeling is unnecessary to connect the pressure hose. The lancet’s soft grip and easy-squeeze fulcrum trigger make operation a pleasure. It includes three nozzles for blasting, cleaning and washing/soap dispensing. A generous 3-quart detergent tank is on-board. A well-balanced steel frame prevents tipping that is common with lighter, plastic housings. At only 63 lbs., it is a breeze to move on large diameter, solid-plastic wheels.


  • 2800 PSI/2.5 GPM
  • Big, on-board detergent tank
  • Fatigue-free lancet operation

  • Only three nozzles
  • Plastic wheels

magnifying-glass-189254_1280Review and Rating

If you find you are struggling to clean with a residential electric power washer, it might be time to step up to gas engine power. The Generac 6596 with its economical price and “big boy” features is that step up. With almost double the power and flow of smaller electric washers, this machine cuts through thick grime and crud in half the time. You will never go back to an electric power washer after using the 6596.

Despite only three nozzles, these did everything we needed from washing the truck to blasting off a year’s worth of dirt and moss from our driveway to cutting through thick layers of dried grass under the riding mower. It is lighter and quieter than many electric pressure washers that we tested.

We love the foot plate on the front, which makes for solid pulls on the starter cord. At around $299, this Generac is less than a hundred bucks more than the best residential electric washer and more portable, so it gets our top ranking in this class.


The Generac 6596 is an incredible package of power, lightness, ease-of-use portability and economy that it never fails to get 5 stars. It is a real bargain considering how capable it is. The 2-year warranty is icing on the cake. This is the best gas pressure washer value in the residential class hands down.

Best High Pressure Water Cleaner Review

If you are considering starting a power cleaning business, then it is unwise to skimp on your main piece of equipment. You absolutely require high pressure, high flow and unquestionable reliability to reap maximum profits, and avoid losing jobs due to machine downtime. With regard to all those factors, we unflinchingly recommend the Dewalt DXPW4240 4,200 PSI 4.0 GPM Gas Pressure Washer with Honda GX390 Commercial Engine. This is industrial-grade power, durability and ease-of-use wrapped up in a compact, highly portable package.

The powerful 390cc, easy-start, quiet, efficient, low-emissions GX390 OHV engine is Honda’s latest generation of GX power plants. It features a high-compression ratio, digital ignition, precision camshaft, ball bearing supported crankshaft and high quality parts throughout. It boasts a 3-year commercial warranty.

It includes a 4 GPM industrial-grade CAT triplex plunger pump with ceramic-coated pistons for high efficiency and reliability. Its design runs cooler and longer, and the pump is completely re-buildable. Built-in thermal relief avoids overheating.

A pro-style steel wand comes with five quick-connect tips in 0, 15, 25, and 40 degree spray patterns plus a soap dispenser, so you can match pressure and flow precisely to whatever cleaning job you encounter. That all sits on the end of 50 feet of a 3/8-inch high-pressure flexible hose to increase access. The machine rolls easily on wide pneumatic tires with solid axles.

It might seem pricey, but considering the build quality, we unhesitatingly recommend it for anyone needing this level of power, durability and portability.


The DeWalt DXPW4240 is the most powerful pressure washer with the highest reliability at this price. This is what a commercial machine should be. It is built solidly, the pump and engine will stand up to hard, daily use and the long wand, nozzle selection and compact design make it very operator friendly.

Matching Pressure Washer PSI to Common Cleaning Tasks

Man using pressure washer to clean up after flooding
A man pressure washes away mud and debris covering what’s left of his sidewalk after the flooding.

Various cleaning jobs require different amounts of pressure and water flow, which are measured as PSI and GPM, respectively. Generally, PSI and GPM increase together with the size of particular machines. Below, we categorize typical cleaning tasks according to how much PSI/GPM they require. This does not mean that a smaller PSI machine cannot perform some of the tasks of larger machines, but the cleaning time will be longer.

1500 to 2000 PSI

  • Removing moss, mildew, dirt films and light stains from windows, siding, concrete and decks
  • Blasting out dirt and moss between bricks and stone
  • Cleaning bikes, toys, patio furniture, garbage cans and washing car exteriors

2100 to 2800 PSI

  • Cleaning boats, vehicle chassis, degreasing engines and transmissions
  • Renewing BBQ grills
  • Stripping wood decks to prepare for refinishing
  • Removing flaking or peeling paint

2900 to 4000 PSI

  • Cleaning construction equipment or vehicle fleets
  • Stripping moss and crud from roofs
  • Cleaning large areas such as parking lots
  • Stripping off graffiti, rust or dried concrete

Above 4000 PSI are commercial-grade power washers that are built for daily, all-day use on particularly large or obstinate jobs such as cleaning cement mixers.

How to Start a Small Pressure Washing Business

A man working with a pressure washing machineA one or two-man pressure washing service is not a particularly difficult business to get into. Capital expenditures are relatively low and the market for cleaning services on a continuing basis is ample.

You should have solid experience or acquire training in order to fully understand safety issues and how to avoid damaging the substrates you are cleaning. Such classes are easy to find. A grasp of business issues is important too.

Be sure to check if any business permits or licensing processes must be undertaken. Carry adequate liability insurance to protect yourself against lawsuits and build client confidence. Do not be stingy about producing professional-looking marketing collateral such as business cards, brochures and ads. Today, online services such as make this step easy and affordable.

As far as which pressure washer to choose, the power washer reviews in this guide should be all you need to make your selection. Depending on if you are serving commercial customers, residential customers or both, you might want to acquire machines with matched capabilities. A combination of the DeWalt DXPW4240 power washer for the big jobs and a 2500-3000 PSI pressure washer such as the Generac 6596 for lighter-duty residential work would be ideal. Because of the requirements for plenty of PSI/GPM and high portability for your business, definitely get at least one gas-powered pressure washer.
