Cold Water Pressure Washer Buying Guide

Also known as power washers, pressure cleaners are powerful tools which clean using water at high pressure levels. Depending on the type of pressure washer, the electric motor or the gas engine converts the low-pressure water to high pressure and pumps it out of the machine through the nozzle. Thus, pressure washers are useful for almost any cleaning job.

However, when you have to get a pressure washer, you may be overwhelmed by the variety and types that are available in the market. You may also come across unfamiliar acronyms such as HP, PSI and GPM. What do they even mean and how important are these terminologies when you purchase a pressure washer? To help you make sense of all these terms, here is the ultimate buying guide to help you choose the right cold water pressure washer.

Maintenance and Care for Cold Water Pressure Washers

As a manufacturer of pressure washers, we understand the importance of maintaining your equipment to ensure its longevity and performance. Here, we’ll cover the essential care procedures for cold water pressure washers, including regular maintenance, troubleshooting common issues and winterization.

Proper Maintenance Schedule

Maintaining your cold water pressure washer involves several key steps.

  • Changing Oil: Just like your car, your pressure washer requires regular oil changes. Generally, you should change the oil after the first 20 hours of operation, then every three months or 100 hours of use, whichever comes first.

  • Cleaning the Air Filter: The air filter prevents debris from getting into the engine. It should be cleaned every three months and replaced every year to ensure optimal performance.

  • Changing Spark Plugs: Spark plugs help ignite the fuel in the engine. Replace them annually or according to the manufacturer’s recommendations.

  • Replacing Worn-Out Parts: Regularly inspect your pressure washer for worn-out parts, particularly the hose, spray gun, and nozzles. Replace these as needed to keep your machine running efficiently.

Troubleshooting Common Issues

Even with regular maintenance, you may encounter some common issues with your pressure washer. Here’s how to troubleshoot them:

  • Leaks: Check all connections for tightness. If leaks persist, consider replacing the o-ring or seal.

  • Low Pressure Issues: This could be due to a blocked nozzle, low water supply, or a damaged unloader valve. Clean the nozzle, ensure adequate water supply, and replace the unloader valve if necessary.

  • Engine Stalling or Overspeeding: These issues are often related to fuel. Check the fuel level, replace old or contaminated fuel, and clean the carburetor.

Winterizing Your Cold Water Pressure Washer

To protect your pressure washer during extreme weather conditions, especially in winter, follow these steps:

  • Drain the Water: After each use, especially before storage, drain any remaining water from the pump to prevent freezing and subsequent damage.

  • Use Antifreeze: Run a pump saver or antifreeze through the system to protect the internal components.

  • Proper Storage: Store your pressure washer in a dry, frost-free place. If possible, cover it with a protective cover to shield it from dust and moisture.

In conclusion, proper maintenance, troubleshooting, and winterization are crucial to keep your cold water pressure washer in optimal condition. By following these steps, you can enhance the longevity and performance of your machine, ensuring it remains a reliable tool for your cleaning tasks.

Cold Water vs. Hot Water Pressure Washers

As the owner of a professional cleaning business, one of your most significant investments is likely to be your pressure washer. The choice between cold water and hot water pressure washers can be a tricky decision, with both offering unique advantages and disadvantages. Here, we’ll delve into the differences in efficiency, cost-effectiveness, and versatility between these two types of machines.

Efficiency and Effectiveness

Cold water pressure washers are highly efficient when it comes to energy usage. They require less power than their hot water counterparts, making them a more eco-friendly option. However, their cleaning ability can be slightly limited, especially when dealing with tough stains or grease. They are best suited for removing dirt, dust, and grime from surfaces.

On the other hand, hot water pressure washers, while consuming more energy, offer superior cleaning ability. They’re effective at breaking down oily or greasy substances, making them ideal for industrial or automotive cleaning tasks. Moreover, the hot water reduces the amount of time required to clean a surface, improving overall productivity.

Cost Effectiveness

When considering the cost of purchasing a pressure washer, cold water models are typically more affordable upfront. They also tend to have lower fuel costs, as they don’t need to heat the water. Maintenance expenses are also generally lower for cold water pressure washers, as they have fewer components that could potentially require repair.

Hot water pressure washers, while carrying a higher initial purchase price, can offer long-term savings due to their efficiency in tackling tough cleaning jobs. Fuel costs will be higher due to the need to heat the water, and maintenance may also be more expensive due to the complexity of the machine. However, the ability to clean more effectively can lead to increased business opportunities and a faster return on investment.


Cold water pressure washers excel in versatility. They’re capable of cleaning a wide range of surfaces, from concrete and brick to metal and wood. However, they may struggle with stubborn stains or grease, limiting their effectiveness in certain situations.

Hot water pressure washers, although not as versatile in terms of the range of materials they can clean, excel at dealing with specific types of grime. They’re particularly effective at removing oil, grease, and other stubborn substances. This makes them a valuable tool for businesses that frequently deal with these types of cleaning challenges.

In conclusion, both cold and hot water pressure washers offer unique benefits. The choice between the two will ultimately depend on your specific cleaning needs, budget, and business goals. By considering the efficiency, cost-effectiveness, and versatility of each option, you can make an informed decision that will help your business succeed.

Any successful pressure washing business owner or dealer knows that the right equipment is key to effective and efficient operations. Among the options available, cold water pressure washers stand out for their numerous advantages, ranging from energy efficiency to affordability. Here’s why you should consider investing in cold water pressure washers.

Energy Efficiency

Whether you’re tackling dirt on a car or grime on a driveway, a cold water pressure washer can handle the task. This versatility allows your business to cater to a wide range of cleaning needs, broadening your service offerings and potential customer base.

Lower Maintenance Costs

With no heating elements or water tanks to worry about, cold water pressure washers are simpler to maintain than their hot water counterparts. This translates into lower maintenance costs, as there are fewer components that could potentially fail and need replacing. Regular upkeep is easier and less time-consuming, allowing you to focus more on serving your customers and less on machine maintenance.


When it comes to upfront costs, cold water pressure washers have a clear advantage. They’re typically less expensive to purchase than hot water models, making them a cost-effective choice for businesses looking to manage their initial investment wisely. Furthermore, the combination of energy efficiency, versatility, and lower maintenance costs means that cold water pressure washers often offer a greater return on investment over time.

In conclusion, cold water pressure washers deliver a powerful combination of benefits that can boost the performance and profitability of your pressure washing business.
