So you have finally decided to buy a pressure washer to ease your cleaning tasks. If you have started researching for the best power washer deals, you are likely to realize that these tools have two variants, gas and electric.
This is likely to make you ponder as to which is more suitable, electric vs gas pressure washer? Generally, several first-time buyers become curious as to whether a gas or electric version is suitable for them or not.
A simple solution here is that each type is better for a unique set of tasks. Although both the models do the same thing, their respective functions, appearance, and cost are different. Here are some of the important points to ask yourself before investing in one.
The 4 Main Points to consider
1) Cleaning Power
This feature is the main function of any pressure washer. It also answers what is a good psi for a pressure washer. However, it can be tough to work this out.
This is because it is gauged in one of the different measurements namely, Pounds Per Square Inch, Gallons Per Minute (GPM), and Cleaning Units (CU). The higher the CU, the more powerful a washer is.
The electric pressure washers usually have a PSI between 1,300 and 1,700. However, it can be higher than the mentioned values too, at least there are some electric models with 3000 PSI and above.The GPM is between 1.4 and 1.5. Thus, the cleaning efficiency is between 5,000 and 10,000 CU. This is enough for ordinary home tasks. However, for heavy-duty duties, you are going to find these pressure washers simply cannot handle.
This is where you need gas pressure washers which are typically more powerful. This is a vital point for the comparison between an electric pressure washer and a gas pressure washer. Their PSI can be up to 4,000 with up to 4 GPM. Thus, their cleaning efficiency is higher and usually comes from a professional-grade model.
When it comes to the difference, they significantly vary in terms of size and weight. This is a vital factor to consider, as it determines the degree of movement you can enjoy while cleaning a few things.
Electric pressure washers are usually less bulky. Thus, you can carry them easily while cleaning fences or cars. On the other hand, gas pressure washers are bulky, as they are set on a strong frame utilizing heavy tires. So, you simply cannot carry them with your hands.
This is where the electric washers win the point. They are easier to store due to their smaller size.
Nevertheless, the gas washers are more widely used in the commercial environments in which storage is not a high priority.
Considering this, the electric models are superior in terms of storage due to their less weight.
Electric pressure washers seem to be more practical, as they have a folding design to shrink into a smaller outline. This allows quick transporting and delivery. Apart from detergent, their maintenance does not need oil like gas models do.

Regardless of whether you want to clean weekly, quickly, or occasionally; a pressure washer is truly an effectual device for cleaning the car’s exterior surface with less water than garden hoses.
For safe use, it is important to choose the right pressure washer and use it in the right way. For car cleaning, a pressure washer must have the desired power measured as Pounds per Square Inch (PSI) as well as water flow measured as Gallons Per Minute (GPM).
A high PSI means more velocity of water while leaving the device’s tip. Similarly, a high GPM means more water leaving the device. The multiplication of these two metrics means Cleaning Units (CU) indicating the mix of force and quantity of water.
For a car, a good pressure washer like this one is perfect. It is recommended to go for a PSI of 1200 to 1900 and a GPM of 1.4 to 1.6 for safe cleaning.
You also need to choose the right nozzle so that cleaning happens without any damage to the paint. For this, you need to look for the size and pressure level of the nozzle. The zero-degree nozzles are not recommended for cars. The other sizes and pressure level are suitable for cleaning in different ways.
