Best Commercial Pressure Washer - Updated Oct 2019

When it comes to cleaning dirt and grime from various types of surfaces, pressure washers may just be considered a heaven sent. They do really well for the task that is assigned to them and they make our lives a whole lot easier, too.

While a lot of homeowners have now considered getting their very own pressure washers to clean things around the house as well as their vehicles, these machines were actually more popular for business owners a few years back. This is because these units used to be very expensive and thus renting it out from a professional cleaning business was a better option.


Why Should You Opt for a Commercial Pressure Washer?

If you regularly use a pressure washer to clean furniture, decks, driveways, vehicles and so on, purchasing your own commercial pressure washer instead of renting one is a more cost-effective choice. While it is possible to opt for units that are made for residential use, they are not exactly designed for regular, everyday use so you might want to opt for a heavy duty one.

What are other reasons for choosing a commercial pressure washer instead of just the regular ones?

  • You have a lot to clean up. Cleaning around the house usually involves spraying pressurized water on patios, decks, driveways, wooden fences and vehicles. However, if you have to deal with dirt or grime from livestock stables, construction sites or even warehouses and other similar commercial spaces, a high-powered power washer would be a better option. Obviously, machines with just 1,300psi of power simply will not cut it.
  • You need to clean every single day. Houses do not usually require thorough cleaning every single day as the dirt accumulated is usually not that much. However, if you own a commercial space or probably run a professional cleaning business, the use of a commercial pressure washer is definitely a must. While it can be a huge expense, you do need this worthwhile investment.
  • You want to save money. Although commercial power washers are much more expensive than their regular counterparts, it can actually become cheaper in the long run. Why so? If you have to use it every day, you would have to opt for a heavy-duty machine that can withstand that much use and using the regular type might only end up costing you more since you would have to replace more often. Obviously, renting power washers or hiring professional cleaners could easily add up, especially if you have to use them every single day.

Purchasing a commercial pressure washer is a huge investment so make sure that you weigh your options very carefully. It might not be a wise decision if you only have your house and cars to clean up but if you have more than that, then definitely consider a professional grade power washer.

How Much Power Do I Need from My Machine?

When it comes to shopping for the best power washers, one of the things that you would first look into is the power that these machines come in. How much power do you really need? It largely depends on the type of work that you need to be done.

Obviously, the bigger the cleaning task that is required, the bigger the power of your machine should be. You need to make sure that the water pressure that the machine can produce is enough to get rid of the dirt and grime in the surfaces that you are cleaning. Additionally, you need to make sure that its machine is strong enough to withstand longer and more regular use.

If you are into cleaning commercial or industrial spaces, you might want to make sure that your machine has around 10 to 12 horsepower.

Also make sure that your unit is able to cater your different cleaning tasks. Sure, strong pressure is needed to clean concrete surfaces but you will have to be very careful using the same amount of pressure on vehicles and glass surfaces as it can peel the paint off or even break the glass!


Gas Powered vs. Electric Powered

In general, gas powered pressure washers are preferred for those who have huge cleaning chores as they are able to produce more power – and thus leave a cleaner surface. On the other hand, electric powered machines produce less power. It should be noted, however, that each one has its own advantages and disadvantages.

Gas powered machines, aside from being more powerful, are easier to move around. Since you do not have to worry about electric cords, you can bring them just about anywhere you want to do your cleaning. It is less environment-friendly though – you will have to deal with toxic fumes and handle gas in the process.

While an electric powered machine seems a lot less advantageous than the two, does have its own plus including being lighter and more portable, if weight is your biggest concern. It is also quieter to operate so you do not have to disturb your neighbors come cleaning time. Sure, it is less powerful but most electric powered pressure washers generally have enough power to do regular cleaning tasks.

Direct Drive or Belt Drive Pump

If you are looking for a commercial pressure washer, the pump is also a very important consideration that you should not miss looking into.

On one hand, a direct drive pump is one where the pump is connected with a hollow shaft to the engine drive shaft. Since the pump runs at the same speed as the engine, it is able to operate more efficiently. Its closer location to the engine also means that it is more compact and thus, less expensive to make. The biggest disadvantage, however, is that it is more prone to vibration and overheating so you will have to deal with a shorter pump life.

On the other hand, a belt drive pump is one where the pump is connected to the engine via belts and pulleys. This set up is less efficient as some energy is lost due to friction, and it also requires more maintenance due to the added parts. On the plus side, the pump is farther away from the engine so it runs cooler. The belt also absorbs most of the vibration thus it spells longer life for the pump.


Hot Water or Cold Water

Another factor that might affect your purchase decision when it comes to power washers is if it uses hot water or cold water. What is this all about?

Well, cold pressure washers are often the most recommended when dealing with dirt removal. It is pretty straightforward – all you have to do is squirt the dirt out, especially in those cracks and other hard to reach areas.

However, if you have to deal with oil, grease or grime, pressure washers that use hot water is definitely a must. Cold water will never be able to remove these types of stains, no matter how much soap you try to use. But, if you add hot water into the equation, you would be surprised at how easily the oil and grime is removed from the surface.
