How Do Pressure Washers Work

Typically, a car pressure washer has a pressure pump that is powered by a gas engine or an electric motor. The pump enhances the speed of the water as it leaves the hose; thus, the water is released at high pressures.

The hose is connected to the washer at one end, and it has a trigger-based gun on the other end. Once this trigger is pressed, the water is mixed with air and then dispersed from the nozzle. The resulting pressure is 75 times more than an ordinary garden hose, which allows it to clean exceptionally well.


5 Benefits Of Pressure Washers on Cars

Whether you run a car detailing business or want the ability to clean your car anytime you want, you need a pressure washer to get the job done right. Here are some of the many benefits of using a car pressure washer.

  1. 1
    Get rid of persistent stains such as oil, grease, grime.  A good car pressure washer can clean all kinds of grease, dirt, and mud, etc. Just select the appropriate pressure settings and point the hose in the right direction. Many of these washers come with additional accessories such as scrubbing attachments for enhanced cleaning.
  2. 2
    Detail your car faster: If you are using a pressure washer for car detailing, it will take you less than an hour. Look for packages that have useful attachments for car detailing.
  3. 3
    A cost-effective solution:  We all know how expensive professional car cleaning services can be; DIY jobs using a car pressure washer can give you similar results at a lower cost.
  4. 4
    Easy to carry around: Most car pressure washers weigh less, and some models even come equipped with wheels. This makes them portable and easy to carry.
  5. 5
    A greener alternative: With a car pressure washer at your disposal, you are not required to use hard chemicals or detergents that are bad for the environment. The pressure is enough for brilliant cleaning.

Buying a Quality Pressure Washer For Your Car

Make sure you consider the following factors when selecting a pressure washer for your car:

Purpose/Location

A compact vehicle has different cleaning needs than SUVs, pickup trucks, or other bigger vehicles. You’ll need a heavy-duty car wash pressure washer to clean large vehicles. Also, if the vehicle in question is parked in a barn, a hydraulic pressure washer would be a good option. Whereas if you want to clean without making noise, using an electric pressure washer for cars might be the right option for you.

Pressure & Cleaning Power

Your garden hose can disperse water at a rate of 5 to 10 GPM (gallons per minute) at 30-50 pounds per square inch (PSI). On the contrary,  light-duty pressure washers provide a minimum of 1.6 GPM flow rate at a pressure of at least 1750 PSI.

Not only does it mean that you get 5 to 18 times more power, but you are also slashing your water consumption by more than half. Simply put, the higher the CPM and PSI, the more powerful would be the car pressure washer, and less water will be consumed.

Pressure Washer Type

There are various types of pressure washers. Here is a brief description of each:

  • Hydraulic Pressure Washer:
    These lightweight pressure washers use a hydraulic mechanism for energy generation without electricity or gas.
  • Diesel Engine:
    This car pressure washer can handle light to heavy-duty work, powered by a diesel dependent pump. But this pump generates fumes, making the machine unsuitable for indoor use. 
  • Gasoline Engine:
    These can handle all kinds of cleaning tasks and depend on gasoline as a source of power for the pump.
  • Electric Motor:
    Electric pressure washer for cars can handle small to large cleaning jobs; they require electricity sourced from a power outlet or generator to function.

Usage

Small areas and cars

Significant-sized areas and big cars – SUVs, trucks, etc.

Large areas and vehicles, brick and stone works, etc.

Storage & Portability

Being portable is an essential quality while choosing the best pressure washer for cars. However, if you are a car service provider, you’ll have to select a larger car cleaning pressure washer for faster cleaning in less time.  Most car pressure washers are portable and can be quickly brought out when the need arises, but the bigger variants with higher PSI and GPM ratings tend to be more prominent in size.

So, choose a machine that provides the best value. Also, a good car pressure washer has storage areas and compartments to keep nozzles, hoses, and other attachments in one place; this limits the chances of these items getting lost.

Durability/Convenience (Ease of Use/Easy Install)

These washers come with plug-and-play features that ensure a smooth installation; you can find a variety of car pressure washers all capable of excellent cleanup jobs.  Just remember that the larger variants have a longer lifespan as opposed to a smaller electric pressure washer for cars.

Extra Features & Accessories

While searching for the best pressure washer for car detailing, you should also look for the following features:

  • Soap or detergent tank:
    A car pressure washer that includes a detergent tank can disperse soap on your vehicle, which allows for better cleaning.
  • Cord and tool storage:
    A well-placed compartment to store the cord, tools, and other accessories is a bonus.
  • Thermal relief and unloader:
    It keeps the built-up heat and pressure in check.
  • Adjustable or replaceable nozzles:
    An adjustable nozzle negates the need to replace outlets between different tasks, just adjust it to generate the required pressure. Whereas, if the pressure washer has replaceable nozzles, attach the one that’s perfect for the cleaning need at hand.
  • Adjustable or interchangeable wands:
    Similar to nozzles, the ability to adjust or interchange wands leads to more functionality and better control of your power washer.

Price & Warranty

The bigger the machine and the higher its PSI and GPM rating, the pricier it may be, therefore choose the car wash pressure washer that is fit to meet all your requirements. This includes making sure that you don't purchase a machine too potent for your car's paint job. Warranty policies vary by product and brand; however, it goes without saying that the more coverage you have, the better.

Electric Vs Gas Pressure Washers – The Comparison

An electric pressure washer for cars is less expensive and comes in handy for lighter tasks and everyday cleaning – typically, such machines generate 1400 to 1700 PSI for adequate cleanup. On the other hand, gas-based high pressure car washers can produce pressure at a rate of 1800 to 4000 PSI, which allows them to handle heavy-duty tasks.  So if you run a car wash service or if you want to do more than just wash cars – choose gas-powered washers.

Watch this video to understand the distinctions and similarities between the two types.


Foam Cannons & Pressure Washers

A foam cannon mixes water, air, and soap to create thick foam, which is then dispensed on the car via the pressure washer. These cannons can operate with any car cleaning pressure washer as long as it does exceed 4,200 PSI and 5.3 GPM. However, if your pressure washer does not have standard fittings, you won't be able to use the foam cannon. You’ll need:

  • M22 x 15 mm connections
  • M22 x 14 mm
  • ¼ inch quick connects

If your pressure washer doesn’t have these connections, invest in an adapter that’s readily available in the market. To learn more about foam cannons and how they lead to better cleanup jobs, watch this video.
