Buying a pressure washer seems simple until you look at the specifications: operating pressure in bar, power in Watts, and water flow rate in litres per hour. The choice between a corded model or a cordless pressure washer adds another layer of complexity. The wrong choice can leave you with a machine that's too weak for your dirty patio or too powerful for your car's paintwork. This guide will help you make an informed decision based on key parameters, ensuring you find the right tool for the job.
What to Consider When Buying a Pressure Washer?
To choose the right pressure washer, it's important to understand a few key specifications. These determine the machine's performance and suitability for your specific cleaning tasks.
Operating Pressure (bar) and Water Flow Rate (L/h)
The operating pressure, expressed in bar, indicates the force of the water jet. The water flow rate, measured in litres per hour (L/h), determines how much water the unit moves per hour. The combination of these two factors defines the cleaning power.
- Light-duty cleaning (up to 120 bar): Suitable for washing cars, garden furniture, and bicycles. A lower pressure prevents damage to delicate surfaces.
- Medium-duty cleaning (120-160 bar): Ideal for patios, driveways, and fences with normal levels of dirt. This is a great all-around choice for most households.
- Heavy-duty cleaning (from 160 bar): Necessary for removing stubborn dirt, moss, and grime from robust surfaces like concrete and masonry.
Type: Corded Electric or Cordless?
The choice between a corded electric pressure washer and a cordless pressure washer depends on your needs for power and mobility.
- Corded Electric Pressure Washer: Generally offers higher and more consistent pressure and water flow. You are not limited by battery runtime. The disadvantage is the restricted freedom of movement due to the power cord.
- Cordless Pressure Washer: Offers maximum freedom. You are not tied to a power outlet, which is convenient for jobs far out in the garden or in locations without electricity. However, the battery life and maximum pressure are often more limited than with corded models.
Accessories
The included accessories determine the versatility of the machine. Common examples include:
- Dirt Blaster: A rotating pencil jet for very stubborn dirt.
- Surface Cleaner: An attachment with a shroud that prevents splashing and cleans large areas evenly.
- Foam Cannon (Foam Lance): For applying detergent, often used when using a
pressure washer for cars.

Frequently Asked Questions about Pressure Washers
1. How much bar do I need for my patio? For a standard patio with green algae or general grime, a pressure between 130 and 160 bar is usually sufficient. For very stubborn dirt on non-sensitive stone like concrete, a higher pressure may be desirable. For best results, use a surface cleaner attachment for an even finish without splashing.
2. Can I use any pressure washer to wash my car? No, excessive pressure can damage your car's paintwork, rubber seals, and other delicate components. Use a pressure washer with adjustable pressure or a model with a maximum pressure of around 120 bar. Always maintain a safe distance (at least 30 cm) and use a wide fan spray—never the pencil jet or dirt blaster.
3. What's the difference between a pressure washer and a high-pressure sprayer? These terms are often used interchangeably and, in practice, refer to the same device. "Pressure washer" is the more formal name for the machine that pumps water at high pressure. "High-pressure sprayer" is a more colloquial term that can refer to the entire unit or sometimes specifically to the spray gun itself.
