How Much Water Does It Use?

For those that care about the environment or are on a water meter, the amount of water it uses is fairly important. It is estimated that the average car pressure washer will use approximately 7 to 9 gallons of water per minute.

When reading the specification of a pressure washer, look for the GPM (Gallons Per Minute) rating because this will give you an identification. A higher GPM will mean more water will come out of the nozzle, which will provide the car with a better rinse. If both ratings are high, then the washing will be much quicker but the efficiency of water used may not be as good.

Foam Cannons

Gas vs Electric Car Pressure Washer

You will notice that all of our recommended pressure washers for cars are electric powered. This is because with an electric pressure washer, you are able to use a high amperage electric motor to deliver PSI of up to 2,000, which is ideal for washing cars.

Gas powered pressure washers deliver a much higher PSI rating with even the low powered versions producing well over 2,000 PSI. There are even some producing over 7,000 PSI but do you really want this sort of pressure hitting your cars paintwork?

Compared with the electric pressure washer, gas alternatives also use more gallons of water per minute due to the fact is has a higher powered motor and brass hardware (in most cases).

Electric pressure washers for cars are much more practical however as its simply a flick of a switch to turn it on. Gas you will be required to tug on a rope in order to get it to start as well as remembering the gas in the first place. There will also be a time when you will need to service a gas powered pressure washer as it will need oil and a new filter in order to run perfectly.

Electric pressure washers are also much lighter due to the materials used but lose the battle when it comes to portability as it will always need to be plugged into an outlet, unlike the gas alternative.

To conclude, the best pressure washer for cars is an electric powered model as there is not a real need for the additional power. Most people want to simply flick the switch and turn on a pressure washer and not worry about fuel, servicing and wondering if they will be able to start it.

Motors and Pumps

The electric motor of a car pressure water and power they output is determined by the wattage and amperage. The three types of electric motors are universal, induction and water cooled. They are in order of cost, performance and noise levels.

Just as important as the electric motor is of course the pump as its must be able to handle the power of the machine. There are three types of pumps, which include wobble, axial and triplex. They are ordered based of their lifespan and ability to withstand large amounts of power.

Other Important Features

There is so much to talk about with regards to an electric pressure washer, so we will keep it short. In terms of usability, electric machines will require a power cord, which needs to be long enough to reach an AC outlet without being near the water spray.

This is not the only length you need to look out for because the hose length is also something that can be either too short or too long. if its too long, it can get in the way of things but too short and you will find yourself knocking over the pressure washer all the time.
