FAQs About 1800 PSI Pressure Washer

I know you have several questions in mind, including whether a 1800-PSI unit is a good fit for your needs. This Frequently Asked Question section is written to help you out on this matter.

1. Is 1800 PSI Pressure Washer Good For Cars?

Experts recommend buying a unit between 1200 PSI to 1900 PSI for washing the painted parts of the car. When washing the parts underneath the vehicle which often get dirty and muddy easily like the wheels, a slightly higher PSI but not more than 2300 PSI is considered.

So, to answer the question “Is 1800 PSI pressure washer good for cars?” Yes, it is.

2. Can I Clean My Driveway With 1800 PSI Power Washer?

Yes, you can, but the real question is whether it’s enough to deliver great result? After a thorough research, I find out that driveway cleaning usually requires a pressure washer with 3000 PSI, although 2800 PSI will also do the job. So, in this sense, 1800 PSI is not the best choice for driveway cleaning.

However, the PSI is not the only factor that affects a pressure washer’s cleaning power. We still have to consider the unit’s GPM. Let say, for instance, your 1800-PSI pressure washer has a flow rate of 3.0 GPM. It would total to 5,400 cleaning power, which is good enough for tough cleaning tasks like that in the driveways.

Pressure washers can be an indoor or outdoor cleaning machine, depending on the brand and model you choose

3. Is 1800 PSI Good For Commercial Use?

As mentioned above, it’s quite difficult to rate a pressure washer unit based solely on its PSI. However, most professional-grade pressure washers often use in light commercial purposes have a PSI of 2900 or 3000 with a flow rate of 3.0 to 4.0 GPM. Thus, we can assume that for a light commercial use, 8,700 to 12,000 cleaning power is needed.

In connection, most 1800-PSI pressure washer units can reach the required cleaning power for commercial use if it has a flow rate of at least 5.0 GPM, which is rarely being offered in the market.


Pressure washers are available in various PSI and GPM levels for some reasons. Moreover, it pays to know if 1800 PSI level is a good fit to your needs. So, don’t buy in haste; take your time; and get the best value product in town.
