Different Sizes Of Pressure Washers

Pressure washers are available in many types, but there are two main types based on the power source. The first is the gas pressure washer mounted with a gasoline engine to power the pump. They provide more power but are more costly and more complex in operations. The second type is the electric pressure washer that uses the electric motor to pressurize the water stream. These pressure washers are not as consequential but are much safer and simpler to use.

Right Pressure Washer For Household Needs

Most of the household tasks can be done using an electric pressure washer. Although the power output is low, they can produce a pressure of 1800 to 2000 psi. Some high-power electric pressure washers can reach a pressure of 2400 psi. This pressure range is enough to clean most household cleaning jobs such as car, deck, siding, and many other jobs.

The size of the pressure washer is not the only thing that affects the cleaning efficiency. There are many other things such as the flow rate, use of attachments and detergents, etc.

If you want to use the electric pressure washer on the driveway, you can do it, although the recommended pressure is higher than the pressure of the electric pressure washer. Driveways and even asphalt pavements can also be cleaned by the electric pressure washer using suitable detergents. Detergent enhances the cleaning capabilities, and there are different types of detergent available in the market for other purposes.

Choosing the high-pressure gas-powered pressure washer is not recommended for homeowners, especially when not purchasing them for regular use. If you are buying your first pressure washer, then using a gas pressure washer can be a little complex for you. Moreover, the pressure range is high and not recommended for light surfaces as it can damage them. The 3000 psi pressure washer on the car surface may remove the paint. With the increased power pressure washer, the risk of injury is also increased, and there should be proper training before using them. You can avoid all of these by choosing the right size electric pressure washer for your home.
