In addition to cleaning decks and siding, power washers can also be used to remove mold and clean lawn equipment.

Their immense strength holds the key. In contrast to a garden hose’s 40 psi of water pressure, a power washer’s output ranges from 1,000 to 4,000 psi, depending on the model.

Top it all off with a 25-foot flexible spray line and superior hose connections, and you’ll be ready to tackle any surface with ease.

An Amazon bestseller, the Simpson MegaShot features a welded steel frame and larger pneumatic wheels than solid rubber wheels that don’t handle uneven ground very well.

Driveway, fencing, patio, pathways, and automobiles can all be pressure washed quickly and easily at 3,200 PSI.

5. Generac SpeedWash 6882

It has long been a well-known fact that Generac makes portable generators, but the company is now making inroads into the pressure washer market.

This is one of the best power washers on the market for use at home or in a small shop.

Smaller engines are significant if you have to move them frequently or don’t have much strength or stamina, and this pressure washer has one of them (196cc).

A 2,900 PSI and 2.4 gallons per minute flow rate give it an outstanding 6,960 cleaning power score (PSI x GPM).

Mold, mildew, and surfaces like wood and concrete can all be cleaned with this pressure washer’s four different attachments.

There’s also an onboard detergent tank for concrete cleaner and a 25-foot hose for those stubborn stains on the go.

According to the manufacturer, the Turbo nozzle can remove dirt and grime up to 30% faster than a conventional nozzle tip.

There is a minor problem with the product’s design. It is essential to be careful when connecting and detaching the hoses because the muffler is on the other side of the vehicle.

If you want to add an extra layer of security, zip tie the exhaust hose to the bottom rail.


  • Spray gun with an ergonomic design
  • A simple-to-push button
  • An engine that is easy to maneuver.


  • Both the muffler and hose are on the same side

Buyers Guide: Things to Look Out for Before Making a Purchase

Water pressure

When purchasing a pressure washer, one of the most significant considerations is how much force it generates.

Pressure is directly proportional to cleaning effectiveness.

Psi, or pounds per square inch, is the unit of measurement used to express this pressure level. In general, a lower psi value indicates lesser pressure.

There is no need to buy the most powerful machine you can find, however. You may be better off using a lower psi pressure washer, depending on how you want to use it.

The typical starting pressure for a home pressure washer is between 1,300 and 1,800 pounds per square inch.

You may use it to wash automobiles, clean shutters, wash lawn furniture and spot clean light stains with this type of low-duty equipment.

Around 2,000 to 3,000 psi is the next level up.

The fact that they may be used to remove difficult stains off siding, driveways, decks, and other surfaces makes these machines popularly known as “heavy-duty.”

Finally, industrial cleaning, paint peeling, graffiti removal, and other uses call for machines with 3,000+ psi of pressure.

Even though these high-end pressure washers are the priciest, most households don’t require a powerful machine.

Gallons per minute

GPM, or gallons per minute, is an essential corollary of psi.

This gauge measures the volume of water that passes through the pressure water. Because they utilize more water, higher GPM models will clean faster and more effectively.

Psi is a direct indicator of how much water a machine uses in a given minute, and the higher the pressure, the more water it will use.

Professional-grade machines have a maximum flow rate of 4 GPM, whereas light-duty machines can only utilize 1.5 gallons per minute.

First, you’ll want to glance at the psi, but you’ll also want to keep an eye on the GPM. You may not be able to support a high-GPM machine depending on your water source.

Source of energy

You’ll also want to look at the power sources of the various pressure washers.

It’s possible to buy gas or electric models, and each has its advantages and disadvantages.

Pressure washers powered by electric motors are often less expensive, lighter, and easier to maintain than those powered by gas.

Aside from that, they’re cleaner, quieter, and better for the environment.

On the other hand, electric models tend to be weaker and require closer proximity to an electrical outlet than gas-powered counterparts.

Cleaning automobiles, patio furniture, and grills are simple tasks that are well suited for this model of pressure washer.

Gas-powered pressure washers also exist. If you don’t want to be tied down by a power cord, these machines are a lot more powerful and adaptable.

Gas machines have the disadvantage of requiring more frequent maintenance and being noisier and more environmentally harmful due to the combustion engine.


Cleaning a concrete surface is more difficult than cleaning other types of surfaces in the home, which is why we’re here to assist you.

The Sun Joe SPX3000 continues to be our top recommendation due to its outstanding qualities and performance.
