How Do I Choose the Right Pressure Washer for My Business?
Choosing the right pressure washer is essential for efficient and cost-effective cleaning in commercial or industrial settings. But what truly matters when selecting the right unit? In this article, we provide an overview of the key criteria and help you find the perfect model for your specific needs.
1. What Are Your Requirements?
The most important question: What will the unit be used for? Is it simply for cleaning dirt, or do you need to remove entire surface layers?
Removing light soiling
For example: dust, mud, or weather-related effects such as moss or algae
- A cold-water pressure washer is sufficient
- Thorough cleaning with low energy consumption
Efficient surface cleaning with high pressure – ideal for removing moss, algae, and weather stains: CLENA M1500 Series
Removing greasy, oily, or stubborn dirt
For example: in workshops, food processing, or agriculture
- A hot-water pressure washer is recommended
- Breaks down tough residues faster and more hygienically
When faced with such stubborn dirt, only heavy-duty equipment will do. The CLENA Serie H5031 delivers powerful cleaning with a flow rate of 30 L/min at 500 bar water pressure.
Large-Area Cleaning
For example: warehouse floors, driveways, stable areas
- High flow rate (liters/min) is essential
- Efficiently rinses away loosened dirt, saving time and effort
When cleaning stables, a high water flow rate is especially beneficial for rinsing surfaces thoroughly.
The CLENA Series M2500 is a popular choice for this type of application.
Layer Removal / Intensive Surface Treatment
For example: paint, rust, lacquer residues, cement haze, or graffiti
– Requires extremely high pressure (often >250 bar) and, if necessary, special nozzles or milling tools
– Ideal: cold-water units with very high pressure and specialized accessories
– Can also be combined with abrasive media when needed (e.g., wet blasting)
High-pressure paint removal made easy: The powerful CLENA Serie H9000 gets the job done.
2. Hot Water or Cold Water?
Cold-water pressure washers are ideal for:
- Coarse, solid dirt
- Outdoor surfaces, vehicles, facades
Hot-water units are especially suited for:
- Greasy or oily residues
- Hygiene-sensitive areas (e.g., the food industry)
The CLENA HOTBOX allows you to upgrade existing systems with hot water functionality.
3. What Pressure Level Makes Sense?
120–170 bar → for light to medium-duty applications and general cleaning tasks
180–250 bar → for professional use in industrial and agricultural settings
>250 bar → for layer removal, e.g., wet blasting
Tip: More pressure isn’t always better – the key is the optimal balance between pressure and water flow. Thanks to the modular design of our machines, we can tailor this ratio to your specific needs.
4. Stationary or Mobile?
Mobile pressure washers are ideal for changing work locations, such as construction sites or vehicle cleaning, or when the unit is not in continuous use.
Stationary systems are perfect for fixed workstations, such as in stables, workshops, or production halls, and offer a space-saving alternative to mobile units.
If no location changes are required, the CLENA SERIES ST high-pressure systems deliver maximum cleaning performance in a compact footprint.
5. Electric, Diesel, or Gasoline?
Electric units are quiet, clean, and ideal for indoor use.
Diesel/gasoline pressure washers operate independently of the power grid and are perfect for outdoor applications.
Maximum flexibility and independence:
The CLENA Series BMK with combustion engine and the CLENA Series GSK with integrated water tank system.
6. Don’t Forget the Accessories
