Features to Consider When Buying the Best Commercial Pressure Washer

Having little knowledge about pressure washers, you might end up buying a non-commercial machine. So, here, we made an effort to give you a good idea about the commercial pressure washers if you are new to them.

1. Gas or Electric Pressure

You must understand the differences between gas and electric pressure washers. A gas pressure washer consumes gasoline to run and produces massive PSI to clean your tough dirt and stains. It creates a lot of noise and fumes. Most commercial machines are gas-powered devices.

On the other hand, an electric pressure washer runs on electricity and produces less PSI than a gas-powered one. These are less in weight and produce less noise and fume. There are a few companies, such as Sun Joe, who make electric commercial pressure washers.

2. Hot or Cold Water

Depending on the water’s temperature, you will find two different types: hot or cold water pressure washers. Most of the machines are made for using cold water as they are widely needed. You can easily clean most of your dirt smoothly with a cold water machine, and they are easy to repair if any problem occurs.

A hot water machine can perfectly clean your oil, grease, or sticky stains. Doing a survey will give you an idea about the type of machine you might need.

3. Commercial Pump Type

A commercial pressure washer pump is a high-pressure reciprocating plunger pump that generates much pressure to clean tough dirt, dust, mud, grime, grease, mold, etc., from a surface. Most commercial machines have used the Triplex Plunger pump because of its high performance and extreme durability.

4. Different Nozzles

If you buy a commercial power washer, it doesn’t mean that all the time, you will be doing heavy-duty cleanings. For your comfortable cleanings, you must use nozzles with more comprehensive degrees, such as 25 or 40, etc. Most of the brands will provide you with around 5 types of nozzles, for instance, 0, 15, 25, 40, and soap applicator.

While applying detergent, your soap nozzle will help you a great deal. All the nozzles use easy-connect technology so that you can easily remove or connect them with your spray gun.

Frequently Asked Questions (FAQ)

1. What are commercial pressure washers used for?

Commercial pressure washers are machines with high PSI and GPM that are used for heavy-duty cleaning. They can be used in large offices, motor car shops, factories, stations, airports, houses, etc. Apart from the mentioned places, you can use a commercial pressure washer anywhere if you feel the need.

2. What PSI is a commercial pressure washer?

PSI 3000 and above is considered a commercial pressure washer. A commercial machine must generally clean the tough dirt, mold, and stain for a large area. Because of this reason, the PSI needs to be higher as the strong stain cannot be cleaned with a lower PSI machine. The GPM of a commercial device is also comparatively higher for the same reason.

3. How important is the pump on a heavy-duty pressure washer?

A pump is part of a pressure washer that generates the pressure on water and sends it through the HP hose and spray gun, cleaning the obstacles. A pump of a commercial power washer needs to be powerful and robust for it to be able to create high pressure and work smoothly. Most of its working capability depends on the pump.

4. How much do commercial power washers weigh?

Commercial power washers primarily run on gas so that they can generate heavy pressure, and gas machines are comparatively heavy. A commercial machine can weigh 80 – 100 pounds or even higher. Because of its increased weight, it becomes difficult to carry the machine from one place to another. Most people use long hoses to cover an extensive area cleaning.

5. What features should a professional pressure washer’s wheels and cart have?

As mentioned earlier, a commercial pressure washer is comparatively heavier and difficult to move around. It would help if you had a strong cart with a metal body and heavyweight, tolerable, maneuverable wheels attached to it. The cart’s surface should not be very high from the ground, so you can easily place the machine onto it.

6. Should I get hot water or cold water?

Hot water is better for cleaning oil, grease, and sticky dirt. The heat of the water and the water force combined are more effective for these types of stains. But maintenance of a hot water machine is not as easy as that of a cold water one. For this reason, people tend to buy a cold water pressure washer. If the working environment doesn’t include only sticky dirt, you should not go for a hot water machine.

7. How much do commercial pressure washers cost?

The price of a professional pressure washer can start from 300 dollars, and it can reach thousands of dollars depending on what type of cleaning you are going to do with it. Some customized machines are really expensive because of their working capability and personalized designs.

8. Can I use my commercial pressure washing machine indoors?

Using your commercial pressure washer indoors is not advisable because there remains a chance of hazards. These machines are large and generate high pressure, which might damage the soft surface of your indoor kinds of stuff. Maintaining specific procedures and taking proper precautions, you use your commercial machines at home to avoid any accidents.

9. Can commercial pressure washing damage paint coating on metal and wooden surfaces?

Commercial pressure washing can easily damage paints on wood and metal because of its pressurized water force. These machines are often used to remove old paint from surfaces like wood and metal. So, don’t use a commercial pressure washer on a painted surface. If it’s necessary to use, you should choose a nozzle with minimum pressure.

10. How do I store my gasoline-powered commercial pressure washer?

You must take certain precautions if you want to store your gas pressure washer for a long time. First, you should remove most of its components, such as the hose, nozzle, spray gun, detergent tank connection, etc. Make sure that you turn off the fuel supply. You can put in some fuel stabilizer if your tank contains gasoline. You can even winterize your machine if you have an upcoming cold season.

Final Thoughts

Commercial pressure washers use high-performance engines and pumps to perfectly combine the water pressure (PSI) with water flow (GPM). Mainly, they produce over 3000 PSI, but you will also get lower machines for light and medium-duty cleanings such as cleaning your car, glass, floor, etc. The above-listed devices are exclusively made for commercial purposes. You will definitely gain if you follow the instructions. Our effort will be successful if you benefit even a little bit.
