5 Best Commercial Pressure Washers – Reviews and Buying Guide
Pressure washers deploy potent streams of pressurized water to quickly blast away accumulated grime such as dust, mold, and dirt from residential houses, decks, vehicles, lawn equipment, driveways, etc. Pressure Washers are powered by a gas engine or electric motor, where a pump forces water through a hose and a concentrating nozzle at high pressure.
Commercial pressure washers are the most significant and potent cleaning machines that money can buy. While most of the cleaning tasks requiring high pressure can be handled by residential pressure washers, cleaning power is not the only factor in determining what type of pressure washer to use. Some residential machines available in the market can produce PSI of 3,500 PSI and 3 GPM; on the other hand, there are commercial pressure washers that can generate 2,000 PSI and 2 GPM but will cost three times more compared to residential washers.

Commercial pressure washers are designed to endure heavy usage (more than 100 hours annually). They use high-grade materials, have more reliable engines, pumps, and components, and are also equipped with high-grade hoses, stainless lances, and brass connections. Apart from the regular cleaning work expected out of a pressure washer, commercial pressure washers can also remove graffiti and take off the paint while repainting. Commercial pressure washers can also inject powerful solvents into the water spray to help remove tough stains that cannot be cleaned with water alone.
There are several varieties of commercial pressure washers available in the market, which makes it a bit overwhelming to decide what will be the best option. Once you understand what your exact requirement is, you can quickly and precisely assess which commercial pressure washer would be the right one for your needs.
Terminology
Pounds per square inch (PSI): PSI measures the amount of pressure discharged by the pressure washer. The higher the PSI, the more power the device washer generates.
Water Flow: Gallons per minute (GPM) refers to the amount of water released from the device in a minute. Pressure washers with higher GPM levels take less time to clean surfaces as compared to models with a lower GPM and also come handy while washing dirtier surfaces.
Nozzle: The nozzle is a fixture at the end of the wand that creates pressure by shaping or angling the spray. Nozzles come with different spray patterns that can affect the width and strength of the spray. A narrower or flatter nozzle creates a more concentrated, powerful spray while a broader spray delivers less direct strength.
An adjustable nozzle lets you change the spray width and pressure with a simple twist of the nozzle. A replaceable nozzle is challenging to switch than an adjustable nozzle, but it gives you greater flexibility by allowing you to use specific, pre-set spray angles. A turbo nozzle provides a broader coverage area by spinning a narrow jet stream in a circular pattern. Finally, airless sprayers can better handle thicker-bodied stains, coatings, and strippers. With an airless sprayer, you also don’t have to carry a pressure water tank around with you.
Nozzle tips are generally available in four options: 0- degree, 15 – degree, 25 – degree, 40 – degree, and sometimes also include soap nozzle in the package. While high-pressure tips deliver a narrow spray with more cleaning power, low-pressure tips have more comprehensive coverage and can be used to apply a cleaning detergent.
Chemical or Detergent Injection: This refers to pressure washers that use cleaners and other chemicals from an onboard tank or other means. The chemical injector allows soap or chemicals to be injected into the water stream, delivering cleaning faster and easier.
Plungers: The plunger is a moving part of a pressure washer pump that moves between the rubber seals, which creates the flow and pressure of a pressure washing system. Industrial grade plungers are generally produced from ceramic.
Thermal Relief: When a pressure washer is operated in bypass mode for a long time, the water temperature in the pump rises, as the water is re-circulated, which can ultimately cause damage to the high-pressure pump. The thermal relief valve infers the temperature in the pump and dumps this hot water while bringing in cold water, preventing overheating of the pump.
Unloader: The unloader relieves water pressure in the pump whenever the spray flow is blocked. The unloader also returns the flow of water to the gun when the operator is ready to clean again.
Things to Consider While Buying.a Commercial Pressure Washer
Pump Type:
Pressure washer pumps come in different varieties, but the most common types of pressure washers are Direct-drive and Belt Drive pumps.
Direct-drive pumps are a low-cost alternative for applications requiring less than 30 hours per week. The pump is connected to the engine drive shaft via a hollow shaft, which causes the pump to run at the same speed as the engine. However, this means that the pump is located very near to the engine. These factors result in the pump running hotter, reducing the lifespan of the bearings and other components of the pressure washer and are prone to overheating and vibration.
Nonetheless, due to the basic connection between the pump and motor, a direct-drive pressure washer is comparatively inexpensive, efficient, and more compact compared to other options. A direct-drive pump is ideal for you if Pressure washing is only a secondary part of your overall work.
A belt drive pump is connected to the engine shaft through belt and pulleys, allowing the pump to operate at low RPMs (almost 1/3 the speed of a direct-drive pump) and also enables the pump to be positioned away from the engine. Furthermore, the vibrations are absorbed by the belt instead of the pump shaft; these factors allow the pump to run cooler, thereby increasing the lifespan.
Most of the industrial pressure washers are driven by Belt-driven pumps, as they are built for extensive use (more than 40 hours per week) and cost more compared to a direct-drive pump pressure washer. Moreover, due to the added friction caused by the belt and pulleys, they are less efficient and also require extra maintenance because of the number of extra components. A belt drive is perfect for you if you are a full-time pressure washer and spend most of most days pressure cleaning.
A wobble pump, which is used for gas-powered models, has lower performance and efficiency than other styles due to spring tension and friction. A pressure washer with a wobble pump requires maintenance every 200–600 hours.
An axial pump has a more abundant oil reservoir and bearings, enabling it to last longer by running cooler. Larger cylinders also enable it to generate higher PSI and GPM ratings.
With pistons similar to a car engine, a camshaft pump can run more efficiently than an axial model. Since it runs cooler than other pumps, a camshaft pump can endure more than 1,000 hours before needing service.
Gas or Electric Powered:
Electric pressure washes generate enough power for small cleaning projects such as cleaning grills, cars, and boats. Electric pressure washers require less maintenance, generate no exhaust emissions, are quieter, cheaper, easily portable, and can be safely used indoors. On the downside, they are less powerful compared to other models and come with higher acquisition costs for the cleaning power. If you are using pressure washers near an electric outlet (like at a warehouse or factory), then electric pressure washers are ideal, and you also won’t have to worry about refuelling.
Gas: Gas pressure washers are ideally used for large projects, and most need pull-starting, regular tune-ups, and fuel-mixing to operate efficiently. Gas pressure washers tend to generate extra power compared to the electric pressure washers and are massive in size. It is not secure keeping gas pressure washers indoors; hence they are required to be anti-freeze for the colder seasons. If you’re a mobile contract cleaner, then gas pressure washers are handy as you are not required to go inside the customers’ house/establishment looking for electrical outlets. Gas models can generate more power for a lesser cost.
Professional Vehicle/Trailer Mounted: Professional vehicle mounted pressure washers can either mount them in the bed of a pickup or get a trailer-mounted unit, allowing you to clean anything you can drive near.
Water temperature
Hot water cleans faster because it “stimulates” the dirt and grime particles to get off the surface. Soap “pulls” the dirt and grime off the surface. The combination of exciting the dirt particles and pulling the dirt particles allows for faster and thorough cleaning. However, sometimes dealing with the burner and burner fuel is a hassle. The hot water generating aspect of a pressure washer will also cost more comparatively due to the schedule 80 heating coil and other components. The burner also requires electricity via an outlet or battery to operate. Coldwater sources are found on residential and some commercial washers and are ideal for home use.
