Pressure washers can easily be described as advanced cleaning equipments that expel water at very high pressure levels so as to attain its incredible cleaning power and efficiency.  Due to this, one of the most important factors to consider when choosing a pressure washer would be its pressure levels.

Different types of pressure washers are likely to have different pressure levels and each type is likely to cater to different types of settings – whether residential, commercial, or industrial.  Pressure washers, depending on type and model, will have a pressure level ranging from 700 PSI up to about 8000 PSI.  In the end, the pressure level you choose will greatly depend on the cleaning applications you will be using the unit for.

There are a number of reputable manufacturers that offer electric pressure washer units with 1500 PSI of cleaning power.  These types of pressure levels are considered as moderate in power and are suitable for a lot of household cleaning tasks such as cleaning the driveway, garage, patio, fence, and walls.  This pressure level is also ideal for auto detailing as using a much higher pressure level may damage or strip the paint off the car.  For commercial and industrial settings with demanding cleaning applications, pressure washer units with 2000 PSI of cleaning power will usually suffice.

Hot or Cold

Pressure washers are usually categorized by the temperature they offer – cold, hot, and steam.  A cold water pressure washer unit is suitable for general cleaning tasks found in residential and commercial settings, most of which do not require the added power of hot water or steam.  The best thing about cold water pressure washers units is that they are compact and lightweight making them very portable as well as easy to store.  This makes them very popular with households and businesses.

If you have a more demanding cleaning task, then a hot water pressure washer will be more suitable for you.  This type of pressure washing unit offers the additional power of hot water which helps to dissolve and lift off any stubborn dirt from the surface.  The truth is hot water pressure washers are ideal for businesses that deals with a lot of grease and oily waste products such as restaurants, fuel stations as well as car engine repair shops.  In fact, hot pressure washers are significantly beneficial when it comes to cleaning poultries and food manufacturing areas as the heated water helps to disinfect their surfaces, making it free from bacteria and more suitable for food processing and manufacturing.

If you require the highest form of cleaning power, then you should turn to steam pressure washers.  These pressure washer units are the best choice when it comes to heavy-duty cleaning tasks as well as heavy degreasing jobs.  The steam that these pressure washer units generate is at 330°F making it very hot.  Add to that steam some pressure and you’ll have the most powerful cleaning equipment there is.  The power of steam and pressure will make short work of dirt, stains, oil, and grease on surfaces as the steam will help to melt and soften them.  The best part in using a steam pressure washer is that it not only cleans the surface, but it also disinfects and sanitizes it.

These days, there are tri-mode pressure washers that can take advantage of the cleaning power of cold, hot, and steam pressure washers.  Depending on the cleaning task you are faced with, you can choose the appropriate temperature settings accordingly.

Electric or Gas

There are two ways a pressure washer can be powered – either by an electric motor or a gas combustion engine.  Gasoline-powered pressure washers have a wide range of use for commercial and industrial cleaning jobs.  These gas units are able to handle various cleaning applications that range from light cleaning duty to heavy cleaning tasks, particularly on industrial settings.  Most gas pressure washers are made for heavy duty cleaning task as compared to their electric brethren which means they are able to stand abuse as well as prolonged usage.

Electric-powered pressure washers on the other hand often come in small and compact form factor making them very easy to move or carry.  There are a good number of businesses who prefer to use electric pressure washers simply because they do not emit any fumes, their noise levels are very low, and they are very easy to maintain.  They also have a very low price tag which makes them very popular among households.  One of the advantages of electric pressure washers is that they can be used indoors or poorly ventilated locations without worrying about carbon monoxide poisoning.

If you are looking for pure mobility, then gas pressure washers are the ones for you.  Unlike electric units, gas units are not tethered to any electrical outlet and are not limited to how far the extension cord can reach.  This allows you to bring it practically anywhere, even on remote locations, and still be able to use it.  The best thing about gas pressure washers is that, size for size, they are able to generate more cleaning power than electric units.  Their only downside though is that they cannot be used on indoor or enclosed applications as the fumes emitted by the combustion engine, the carbon monoxide gas, is particularly harmful when exposed to for prolonged periods.  Other disadvantages would be higher noise levels and higher maintenance requirement.

Belt or Direct Drive

There are two ways the high pressure pump can be powered – either by belt drive or direct drive.  Belt drive uses a belt and a pulley system to transfer the power from the motor to the pump.  Since the pump and the motor are not directly connected, the heat of the motor is not transferred to the pump.  In addition, the vibration generated by the motor is absorbed by the belt freeing the pump from wear caused by vibration and heat.   The disadvantage to using this type of configuration is that the distribution of the equipment will make it take more space.

Direct drive on the other hand powers the pump directly.  Although the layout subjects the pump to the heat and vibration of the motor, it also makes the form factor much smaller, making it occupy lesser space.  Due to this type of configuration, manufacturers are able to create more compact pressure washer units that are highly suitable for light to medium duty cleaning.
