If you must use a pressure washer for cleaning your car or driveway or a number of other tasks both around your home and your business, which is the best commercial pressure washer to buy?

With so many different manufacturers constantly sprucing up their designs and with new models coming out all the time, it can be difficult to tell the good units from the bad in a hurry.

And then there’s the issue of the warranty: you need to know that if your unit fails, you have a solid warranty backing you, and not some 2-year limited warranty.

With that said, let’s cut to the chase: below is a list of the best commercial pressure washers to buy in 2021.

Frequently Asked Questions (FAQ)

What are the top 10 pressure washers?

According to whom?

For this list, we consulted a variety of experts including equipment manufacturers, trade organizations, and on-line consumer review sites.

To come up with the top 10, we aggregated the ratings from reputable consumer-based electronic review sites that have tested pressure washers. Our goal was to spend hours doing hands-on research and a simple Google search for pressure washers did not cut it.

Thus, we compiled this list to help you quickly identify the best consumer-rated pressure washers.

How many PSI is a commercial pressure washer?

The answer depends on the model. The general rule of thumb seems to be around 4,000 PSI for residential and 3000 PSI for commercial. Just keep in mind that the PSI rating is not a guarantee for the strength of a washer. This number is an average.

There are lower end residential units that reach 3,500 PSI, but they generally don't leave a flawless clean. If you want a unit that is really going to leave your driveway or patio sparkling clean, a commercial-quality unit is probably the way to go.

Which is the most powerful pressure washer?

There are many models out there which are professional-grade and designed to break down grease, grime, mold, mildew, and dirt that would otherwise be almost impossible to remove without a pressure washer.

However, when it comes to power, it's hard to determine which machine is the most powerful.

The main difference between power and input power is that the former is about the amount of work being done. That is, the amount of mass it can clean off an object.

As for the latter, it's the amount of energy required to drive the pump. This can be compared so you can determine which model will work for you.

What is the best pressure washer for home use?

I think the easy answer to your question is what you should use is the pressure washer I am reviewing. However, that would benefit me more than you. Instead, I will suggest the category of pressure washer that might be best for someone with little to no experience using or buying a pressure washer and then, point out some specific features and specifications you may find useful.

These would be the best pressure washer if you are new to the scene.

I would recommend a Cold-Pressure washer specifically because they are most commonly used for general household cleaning. They can go from small jobs like washing the dishes and cleaning off the driveway, to larger jobs like contracting and cleaning concrete. Essentially, a cold-water pressure washer can be used for anyone looking to remove dirt on a large or small scale.

Conclusion

If this is your first time buying a pressure washer, then you might not be prepared for the sheer number of choices you’ll have. We’ll tell you which factors to consider in the buying process, so that you’ll have the best chance of getting your high-pressure job done the right way. Take a look at our list of the best commercial pressure washers for all of your cleaning needs.
