Best Commercial Pressure Washer Reviews (2019): Our Industrial Picks

When it’s time to clean grease and grime from restaurant equipment, vehicles, or driveways and sidewalks, you need a commercial hot water pressure washer. But what qualifies a pressure washer to be commercial-grade?

To illustrate the advantages of a commercial pressure washer, let’s look at some facts. In this manner, you can make a smart decision about which model best fits your needs.

The first feature to examine when shopping for a pressure washer is the flow rate. The higher the flow of water, the better the washer will clean. Flow is presented in GPM or gallons per minute.

Next, the pressure isn’t everything. In fact, instead of looking at PSI, do the math to discover the cleaning units. All you have to do is multiply the flow rate by the PSI. For example, you’ll want at least 9000 cleaning units to remove graffiti. To find the washer that offers 9000 cleaning units, look for one with the flow rate of at least 3 gallons per minute and 3000psi.

To clarify, any pressure washer that provides at least 3800 cleaning units is considered medium duty. And heavy duty is anything over 7600 cleaning units. You’re likely to find that most of the pressure washers in this range are gas powered.

Finally, hot water is a necessity if you need to remove oil and grease. Otherwise, cold water will simply push the dirt around. Although hot water pressure washers require more maintenance, they save a lot of effort and time. Plus, some have a steam option, too.

We hope our reviews of the top commercial pressure washers guide you to exactly what you need.

Kranzle makes some of the best commercial pressure washers with hot water in the business. A lot of that is due to their industrial grade pump design. Their pumps can handle waiting in bypass for hours at a time and even run dry without being damaged. They also self-prime. Not only that, but they are freeze proof in cold weather. Even if water freezes inside the pump, it won’t be ruined.

(In case you’re wondering what bypass means, it’s when the pressure washer is operating but not spraying, as when the trigger is not being depressed. Most electric pressure washer brands will warn you to not place their machine in bypass for more than a couple of minutes at a time.)

Next, this Kranzle 1165 pressure washer comes with a 65-foot braided wire hose on a reel, plus a Dirt Killer turbo nozzle. It has a flow rate of 5 gallons per minute with 2400 PSI or 20,000 cleaning units. In addition, it offers digital temperature control, and it’s steam-capable. In conclusion, if you need a pressure washer for agricultural or industrial purposes, this is one of the best gas pressure washers you can buy.

Two common problems that can ruin a pressure washer

Two things can damage your new hot water pressure washer unless you take care of them. One is improper lubrication. High-pressure pumps like the ones on a power washer need clean oil to deal with the friction and heat. Keep an eye on your oil levels, checking them before each time you use the machine.

The second problem is operating the washer in bypass mode. That’s when you have it running, but you don’t pull the trigger. The water recirculates in the pump and heat from the hot water builds. The only exceptions to this rule are the Kranzle pumps that tolerate bypass mode for long periods or pumps with a thermal relief valve. To avoid trouble, just turn off the washer if you won’t be using it again soon.

Conclusion

Commercial grade high pressure power washers are excellent for tackling tough jobs. Restaurants use some of the best gas pressure washers on the market to clean greasy equipment. Fleet services employ them to maintain their vehicles. And we hope you found the perfect power washer for your job today, too.
