AR pumps are known for their ability to run a lot cooler and their ability to produce the same pressure and GPM but with less HP. This means that less gas is used because the engine works less but can still produce efficient cleaning power.

What To Look For In A Commercial Pressure Washer

Finding the best 4000 psi pressure washer should be easy since there are a lot of options available in the market nowadays. To help you out more, I listed the things that you should consider when shopping for a professional power washer.

Pressure washer for commercial use should have a minimum cleaning power of 16,000 CUs

  • Cold Vs. Hot Water Option

You can choose between cold water pressure washer or hot water pressure washer to use as the main cleaner for your business. However, it is best if you have both units.

Cold water power washers are great for removing dirt off any surfaces. On the other hand, hot water power washers are ideal for cleaning areas where grime, oil, and grease are constant.

Hence, you have to consider the nature of your business to know which option best suited your cleaning needs.

  • Direct Vs. Belt Drive Pump

If there is one important part of the pressure washer that you should not compromise, then it would be the pump. Basically, there are two major pressure washer pumps to choose from, namely: the direct drive pump and the belt drive pump.

Wondering which one is the best drive pump for commercial purposes?

Most commercial grade pressure washers are used every day. In fact, the majority of your day would probably be spent using the power cleaner. If this is the case, then you should pick a 4000 psi pressure washer unit with a belt drive pump.

Why choose the belt drive pump?

Belt drive pumps are more durable and can last much longer. They are also very good at absorbing vibration during operation. Lastly, belt drive pumps don’t overheat easily. It would take major pump issues for the pump to overheat.

The downsides of belt drive pumps are inevitable though (as there is no such thing as the perfect product). Belt drive pumps are quite expensive, not to mention that they need more maintenance as compared to the direct drive pump.

  • Pump Protection

To make your pressure washer last even longer, you need to choose a unit with thermal pump protection. This will serve as an added protection to your pump so that overheating will not be an issue.

What thermal pump protection does is that it acts as a fan motor protection. It uses a thermal relay to break the power circuit if the temperature is at the level that would cause burning.

  • Pneumatic Tires

There’s no better option when it comes to pressure washer tires for outdoor use than the pneumatic tires.

Why?

A lot of pressure washer experts agree that the wheels play an important role in the maneuverability of the unit. And pneumatic tires have always been on top of the list when it comes to buyers’ choice.

So, what makes pneumatic tires the best option for commercial cleaners like 4000 psi pressure washers?

Pneumatic tires have excellent ability to absorb impact and shaking, as well as the ability to absorb uneven terrains. Hence, you can move the unit with ease for a smoother operation.

  • Sturdy Frame Construction

Why should you consider the frame construction of the power washer? Well, the frame serves two functions— (1) for protection of the pump and engine and (2) for added durability.

Cleaners for commercial uses should be highly durable as they are used on a daily basis. So, make sure you get a unit with sturdy frame construction. Make sure it is welded properly and is powder-coated to resist rust and corrosion.

How To Change Engine Oil Of Your Honda 4000 PSI Pressure Washer

The Honda 4000 PSI pressure washer works on fuel. If ever you find your machine lacking oil, then you simply have to change the engine oil to clean out the old supply and add in some new one. If it is going to be your first time to change oil, then you can simply follow the steps that we’ve laid out below:

  • Put a bucket under the pressure washer pump oil drain plug
  • Take out the drain plug and the oil filler cap
  • Drain out the old oil
  • Change the drain plug
  • Fill the pump with new oil

Note: You should always follow the oiling instructions stated in your manual to ensure that you put in the right type and amount of oil your machine needs. Most Honda pressure washers need DP70 oil but SAE 30W oil can work as well. But to be sure, check your manual.

Top 3 4000 PSI Electric Pressure Washer Applications

At a pressure rating of 4000 PSI, a pressure washer can already be considered an industrial pressure washer since the strength can be used for big areas that usually collect a lot of dirt and debris.

That being said, we’d like to list down the top 3 uses for a pressure washer of this kind of caliber:

  • Factories And Plants

We’ve mentioned that this kind of power has industrial applications. One of the main uses of this industrial powerhouse is factory and plant cleaning. Since factories collect a lot of sticky dirt, you’ll definitely need a 4000 PSI pressure washer with a high flow rate to take care of all areas.

  • Office Buildings

Just like with factories, a 4000 PSI pressure washer can be used on big office buildings or condominiums for that matter.

  • Big Parking Lots

If you own a parking lot, then a 4000 PSI pressure washer can do a good job cleaning the big area. A lot of homeowners with large parking spaces or backyards use strong pressure washers to handle dirt and debris.

4000 PSI Pressure Washer Safety Reminders

It doesn’t take a genius to know that a 4000 PSI pressure washer can be dangerous if you don’t know how to use it properly. A 4000 PSI pressure washer has enough power to push you back if you’re feet around steady on the ground. So, you can only imagine how harmful this kind of machine can be in the hands of a beginner who didn’t read the manual.

If it is your first time using one of these machines, then you need to take note of these safety reminders:

  • Never point the pressure washer at any person, object, or breakable/fragile area.
  • Always wear long sleeves, long pants, gloves, boots, and goggles.
  • Never use the pressure washer from an elevated surface such as a ladder or a set of stairs.

Are 4000 PSI Hot Water Pressure Washer Safe To Use For Home Use?

We mentioned a while ago that 4000 PSI hot water pressure washers often used for commercial purposes such as washing plants, factories, or big buildings.

However, can you use it at home? Can the strong power do more damage than good to the paint or the tiles?

The answer to that is yes, a 4000 PSI pressure washer can damage your paint or tiles if used at maximum power. It may be good for brick houses or homes with materials of similar density. But weaker materials may not be able to take the power. That said, you can actually use a 4000 PSI pressure washer for your home, but it might be a waste since most homeowners can’t utilize the full power anyway.

We can recommend you to use the 4000 PSI pressure washer if ever you own a big house that’s made out of strong material like concrete or brick. But if you have a medium to small-sized house, then it is definitely not recommended. You might as well save yourself some money and buy a weaker pressure washer.

Conclusion

If I were to recommend the best 4000 psi pressure washer from the list, it would be the Pressure Pro E4040HC 4000 PSI CAT Pump Gas Pressure Washer. Pressure Pro E4040HC CAT pump cleaner has a highly durable pump which, for me, is the most important feature for commercial grade cleaner.

Although AR pump is easier to rebuild and runs much cooler, the CAT pump is still highly efficient and can pull much pressure even with a long pressure washer hose. It is also an eco-friendly power washer cleaner with impressive belt drive pump and thermal sensor protection.

With proper maintenance and a premium thermal pump protector, Pro E4040HC 4000 PSI CAT Pump Gas Pressure Washer will promote more uptime, thus you can do more tasks in less time.
