There is a plethora of pressure washers on the market. You will have the option of investing in either a consumer range pressure washer or a professional pressure washer.
The difference between these 2 categories comes in terms of the reliability and longevity of the equipment, and the work you can do.
High-pressure cleaner for the general public
A high-pressure cleaner for the general public will be intended for domestic use. It will be limited in terms of pressure and flow, and cannot be used intensively. This will be suitable for small jobs around the house such as cleaning garden furniture, cleaning the car or scooter, a terrace or a wall, etc.
Professional high-pressure cleaner A professional
High-pressure cleaner will be intended for intensive use, with greater pressure and flow. We will discuss in this section only the use of high pressure cleaners for professional and industrial use.
The criteria to consider when choosing the right industrial or professional pressure washer
Pressure The pressure
Unit of a pressure washer is expressed in bar. The water sent under pressure will make it possible to clean or strip a surface. This pressure or impact force of the water must be adapted according to the surface to be treated.
Water
Flow The water flow is expressed in liters per minute or in liters per hour. The flow rate does not affect the quality of work on the surface to be treated. Throughput will simply allow you to complete a task more or less quickly. A strong flow will bring a significant flow of water which will push the dirt and evacuate it more quickly.
Hot or cold water
High pressure cleaner A hot water high pressure washing has a boiler that can raise the temperature of the water up to 155 degrees depending on the cleaner model. This hot water sent under pressure will clean greasy surfaces more effectively with a working pressure that can be reduced. The other advantage is that the use of detergent can be limited.
Hot water cleaners are mainly powered by electricity. Some manufacturers offer stand-alone hot water cleaners that work with a gasoline or diesel heat engine.
Professional high pressure cleaner
It will deliver a working pressure of up to 300 bar. These devices are robust and are designed for prolonged use in the professional and industrial field.
Very high pressure cleaner
It will deliver a service pressure of 300 to 700 bar. This type of high-pressure cleaner will mainly be aimed at professionals, for demanding high-performance cleaning tasks.
Ultra high pressure cleaner
It delivers a service pressure of over 700 bar and up to 3000 bar. This type of equipment will be used mainly in the industrial sector where very high pressure is required.
A professional pressure washer adapted to your activity
It is important to have a device adapted to your professional activity, in order to obtain the expected results in terms of cleaning and performance.
Example below with the stripping of antifouling paint on a boat hull. Your cleaner will need to have enough pressure to strip the paint, and enough water flow to get the job done as quickly as possible. On a construction site like this, the equipment will have to be adapted to intensive use. An autonomous high-pressure cleaner with a combustion engine may be used. You can also choose a high-pressure cleaner that can operate with seawater.
