Let’s dive in!

How to Find the Best Power Washer for Your Needs

Pressure washers are used for various tasks around the home, the workshop, the farm, or on commercial jobs.

Choosing the correct power washer mostly matches 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 the brick, tile, or stone facades
  • Cleaning your car’s or boat’s exterior
  • Washing patio furniture, garbage cans, bikes, and other toys

The 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 quick and simple.

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

Usually, this pressure range requires power from gasoline engines. The best pressure washer for car cleaning is in this category: the Greenworks 2000 PSI 1.2 GPM Pressure Washer.

This electric pressure washer puts out 2000 PSI and 1.2 GPM and features a convenient onboard soap tank.

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

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 peek 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.

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.

We have selected a range of models for light-duty to heavy-duty tasks in each category.

Sun Joe SPX3000 2030 PSI 1.76 GPM Electric Pressure Washer

Sun Joe SPX3000-BLK 2030 Max Psi 1.76 Gpm 14.5-Amp Electric Pressure Washer, Black
  • [POWERFUL]: 14.5-Amp/1800-watt motor generates up to 2030 psi/1.76 GPM for maximum cleaning power and water inlet temperature (max) is 104 degrees Fahrenheit
  • [VERSATILE]: Tackle a variety of cleaning tasks: homes, buildings, RV’s, cars, Trucks, boats, decks, driveways, patios, lawn equipment, and more
  • [TSS (Total Stop System)]: Automatically shuts off pump when trigger is not engaged to save energy and prolong pump life
  • [QUICK-CONNECT TIPS]: 5 quick-connect spray tips (0º, 15º, 25º, 40º and soap) tackle light, medium and heavy duty cleaning tasks
  • [DUAL DETERGENT TANKS]: Two 0.9 L onboard, removable tanks carry and store different types of detergent to simultaneously tackle different cleaning projects

What We Like

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

What We Don’t Like

  • Wish the pressure hose was five feet longer

Review 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.

The larger-than-average wheels also 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 the pump life.

The Verdict

Buyers’ Sun Joe pressure washer reviews are nearly unanimous in finding this blaster 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 recommend this as an excellent value.

  • Three nozzles plus soap tip for pressure and width control
  • On-board detergent tank

The Verdict

If you have surveyed as many AR pressure washer reviews as we have, you know this is a very popular residential-grade electric power washer.

The highly flexible hose, nickel gun, wand, 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 dried concrete or rust layers.

It is safe for paint prep as it will not tear up aluminum or wood material. Its price 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; the 390SS is a perfect example.

You will be impressed by how quietly and efficiently this high-value machine handles cleaning tasks.

  • Easy-roll pneumatic tires

What We Don’t Like

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

The Verdict

Given the amount of power and flow the Simpson MSH3125-S 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 onboard detergent tank.

Otherwise, the cleaning power is definitely there, which would shame less expensive electric power washers.

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.

Overall, this gas pressure washer from SIMPSON Cleaning is one of the best gas-powered Simpson pressure washers in the market, which provides many features at a very low price. We like it a lot.

The Verdict

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.

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 Generac 8874.

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 footplate on the front, which makes for solid pulls on the starter cord.

The Generac 8874 costs less than than the best residential and most portable electric pressure washers, so it gets our top ranking in this class.

The Generac 8874 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 the icing on the cake. This is the best gas pressure washer value in the residential class.

Matching Pressure Washer PSI to Common Cleaning Tasks

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.

1500-2000 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

2100-2800 PSI

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

2900-4000 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 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 Fiverr 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 whether you are serving commercial clients, residential clients, or both, you might want to acquire machines with matched capabilities.

A combination of the SIMPSON Cleaning PS4240 4200 PSI 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, you should definitely purchase at least one gas-powered pressure washer.
