Things to consider when buying a pressure washer:
- Power source. You’ve got a few choices here:
- Gas-powered. These pressure washers are the most powerful and offer the best of both world: mobility as well as great PSI and clean.
- Electric-corded. Electric pressure washers offer solid power but come with the hassle of having to deal with an extension cord.
- Battery-powered. Very portable but not as powerful as the others. You’ll also have the risk of running out of battery power unexptectedly.
- Pressure. Measured in PSIs (pounds per square inch). This is the power or strength with which the water is coming out of the washer. The higher the number the more power the machine has and the cleaner the job it does. You can buy a machine with pressure as low as 1000 PSI or as high as 4500 PSI and above.
- Water consumption measured in GPM (gallons per minute). This is the amount of water coming out of the pressure washer. GPM works hand in hand with the PSI. The higher the numbers, the more power the machine has and the cleaner result you can expect. Pressure washer water consumption can be as low as 1.5 GPM and less or 4.5 GPM and more.

Pressure Washer Guide
As you choose the best pressure washer have the kind of job you want to do in mind. Making the best choice out of tens of pressure washer reviews will be easy, from professional cleaning engagements, commercial cleaning to residential cleaning jobs, such as spring cleaning just after the dusty and untidy summer months. Having your cleaning intentions in mind will help ensure the most ideal machine for the rightful application has been selected.
For home use, the best pressure washer is perhaps an electric one with 1300-1900 PSI. It’s superb for washing cars, patios, grills, small decks, lounge furniture, play sets made of plastic, among others.
Choose a lightweight, compact pressure washer with a high-pressure flexible hose. Electric pressure washers are quiet and rather light with little in terms of maintenance required. Exhaustion emissions are absent and stop or start through a trigger. A compact size means that an electric pressure washer can be kept indoors.
Nonetheless, the low pressure will translate in slow cleaning. The nozzles and wands made of plastic aren’t as strong as metallic ones. Being electric mean an outlet is required around the area of activity.
Residential and light-commercial use
The best machines for shop use and residential homes with an improved cleaning power are gas-powered pressure washers. A range of 2000 PSI to 3100 PSI should be fine. It means a grimy surface will be cleaned within a third of the time it would take the fastest electric pressure washer.
However, expect the gas-powered machine to be heavy, noisy with cumbersome tune-ups, fuel-mixing and even pull starting. In colder regions winterizing the pumps using anti-freeze would be needed considering, unlike the electric pressure washer, it cannot be stored in a residential property. Lots of control and user caution is needed in gas ones to lower the risk of damage to the surface being cleaned while avoiding injuries to the user.
With a gas pressure washer of between 3200PSI and 4200 PSI, you’ve a gas model ready for professional duty such as surface preparation, stripping paint, cleaning a construction site, maintaining a fleet, removal of tough graffiti, among other applications.
The rule of the thumb is that in case maximum power is all you need, including rapid cleaning, gas powered models are the best. But for simple home use and residential surroundings the convenient choice would be electric models.
In a nutshell, while choosing the best pressure washer PSI (pounds per square inch), the pressure output is a critical factor. It can help you determine the best model to choose.
Light-duty: 2000 PSI and lower pressure washers that are superb for cleaning sidings such as boats, trucks, cars, fences, decks, driveways, sidewalks and patio furniture.
Medium-duty: Models generating 2000 PSI to 2800 PSI and apart from handling those cleaning jobs also done by light-duty models, they’re exceptional for cleaning patios, decks, fences and sidings.
Heavy-duty: With a PSI of 2900-3300 these models will rapidly complete cleaning jobs, including sidewalks and other small sections with the additional benefit of handling wide driveways and other large areas like cleaning a second story or preparing surfaces for paint application.
Professional/extra heavy duty: Any pressure washer with a 3300 PSI and above falls in this category. They handle diverse cleaning jobs the other models can handle, but bring in extra power in the job, especially in paint prep projects.
GPM also matters
Apart from PSI, it’s important to note the gallons per minute (GPM), which is the volume of water the pressure washer promises to deliver. A higher PSI mean intense cleaning while an increased GPM represent quality cleaning and ensuring surfaces hard to reach are rinsed perfectly. As such, to ascertain the best pressure washer with the best cleaning power both GPM and PSI are important considerations. The larger their combined number the larger the cleaning efficiency.
Features to checkout
The best pressure washer should have an onboard soap tank. Otherwise, you’ll have to grapple with using lots of different containers. Another advantage is a cord and tool storage. A pressure washer with wheels is much better in case it’s a heavier model, such as a gas-powered 4200 PSI model. Rather than replaceable nozzles, go for the convenience of adjustable nozzles as a simple twist will have the spray pressure or width changed with ease.
Nonetheless, replaceable nozzles are better off when you desire certain spray angles to extend spraying options.
Pressure washer and your car
Clearly a pressure washer is perfect for general cleaning tasks from blasting off dirt from walks, concrete floors to decks. However, their pressure is so intense they can easily destroy your car’s paint. A hose is a better suggestion to maintain the integrity of your car’s paint. However, if you’re careful to avoid damaging car paint, a pressure washer is a superb way of giving the car a tidy job. To clean your car with a pressure washer remember to:
- Always have the setting set delicately to around 2000 PSI
- Choose a nozzle that has an extensive spray pattern to avoid paint damage
- Clean up the car while on asphalt, concrete or any other hard surface
- Avoid spraying inside a car’s engine with a pressure washer
- Maintain a good distance between the nozzle and the car fragile parts such as lights and windows
Own or Rent a pressure washer?
When it comes to owning your own pressure washer or renting for a few hours, day or week, it draws down to a few things.
Frequency of use-How long do you intend to pressure wash? Do you need the machine once every year during spring cleaning or to complete a single yearly surface cleaning? If you only need a pressure washer once a year renting makes a lot of sense. However, if you love cleaning your roof, deck or concrete walkway a couple of times annually the cost-effective solution is to get your own. Where a pressure washer is required for a day job only, without the need of the equipment in the near future, it might be wiser to rent.
Cost-The cost of the best pressure washer varies, especially if you run through all the pressure washer reviews around. Renting a pressure washer depends on the area where one lives. Considering the cost of hourly or daily renting the equipment vis-a-vis the cost of buying the type of model you want, you can easily know whether renting makes sense or buying one is the answer. For instance, rather than rent $65 per day three times a year or more, purchasing a gas-powered $280 pressure washer is better.
Repairs and maintenance-Renting a pressure washer mean that any malfunction will be handled by the owner and not you. If you decide to purchase one, you must factor in repairs and maintenance. There’s always a chance the item could break down or some parts destroyed or require replacement. Owning a pressure washer requires dedicated maintenance.
Better results with a pressure washer
Get the best out of your pressure washer by ensuring its GPM (gallons per minute) requirement is met by your water supply. Depending on the surface or item being cleaned, you can get the best out of your pressure washer by:
- Standing on a surface that’s stable throughout to ensure you’ve a solid footing and good general balance.
- Using the manufacturer specified type of eye protection and proper specified hearing guard in the case of a noisy gas model.
- Avoiding being distracted so much that you leave an active spray gun running and unattended.
- Choosing the right spray setting or nozzle considering nozzles that focus their power intensely can destroy various surfaces. If not sure find more about spray settings and spray tips from the user manual that’s fit for the type of surface being cleaned.
- Being aware all the time of the area the spray is always directed. Avoid pointing the spray gun at plants, animals or people. Power lines, power sources and electrical fixtures should be far from the line of the spray at all times.
Choosing the right nozzle
As already mentioned, the spray angle and the orifice size of the nozzle determine a specific pressure of flow of water. Familiarize yourself with GPM and PSI to ascertain the best cleaning power for the kind of cleaning project in your hands.
An increase in the size of the nozzle will see the pressure washer’s PSI reducing without a change in the flow. Using the un-loader to lessen the pressure diminishes GPM and PSI. The trick is to reduce PSI of the pressure washer you’re using by having the nozzle size increased to keep GPM maximum.
The spray angle can be anything between 0 (zero) and 65 degrees. Lots of contract cleaners will not have any difficult with 25 degree spray angle wash patterns. But 40 degree spray angle wash pattern is a preference of many contract cleaners; it allows them to hold the nozzle and to be nearer the surface being worked on. The same contact width is obtained that delivers an intense pressure and increased temperature right at the heart of the contact point.
Even so, keeping the nozzle a good distance away consistently from the surface is important. Zero degree type of nozzle mean that all the cleaning power will be concentrated on the smallest area with an impactful cleaning power heavily at the center. As a result, the cleaning effort is done with tremendous power. Note that some zero degree nozzles leave tracers or wand marks that a rotating nozzle can easily solve.
Optional accessories for pressure washers
While not all models work with optional accessories, the best pressure washers work with optional accessories and diverse tools for efficient cleaning results. These include:
- Chemicals-Available depending on the cleaning type and only specified pressure washer types of chemicals by the manufacturer should be used
- Brushes-Allows the user the ability to scrub while using a pressure washer
- Spinning jet surface cleaners-superb for cleaning sidewalks and driveways
- Angled wands-Great for cleaning gutters (only extensions are needed)
- Extension wands-Best where cleaning involves home exteriors
- Rotating nozzle-To ensure no wand marks/tracers are left behind
