How to choose a petrol pressure washer

My first piece of advice is to prioritise the machine’s pressure output. Aim for a unit delivering at least 2000 PSI (pounds per square inch) for most domestic tasks, such as cleaning vehicles, driveways, and patios. For more demanding applications like removing mould or graffiti, consider options exceeding 3000 PSI. This metric directly influences the device’s capacity to tackle tough grime effectively, making it a key parameter in your decision-making process.

Next, assess the flow rate, measured in litres per minute (L/min). A higher flow rate enhances cleaning efficiency, allowing for better rinsing and coverage. Machines with a flow rate of around 7 to 10 L/min are generally suitable for household use. If your projects are larger or require increased water volume, opt for models with flow rates of 12 L/min or above.

Don’t overlook the type of pump used in the cleaner. Triplex pumps are typically more durable and provide consistent pressure, while axial pumps may be more common in budget models. If you expect to use the machine frequently or for heavy-duty tasks, investing in a model with a robust triplex pump will yield better long-term performance.

Another critical factor is the weight and portability of the unit. Heavier machines may offer more durability, but ensure that they are still manageable. Look for features like large wheels and ergonomic handles to enhance mobility and ease of use. Additionally, consider the fuel tank capacity, as this will dictate how long you can operate before needing a refill–larger tanks are preferable for extended cleaning sessions.

Finally, examine the accessories and attachments included with the cleaner. Various nozzles, brushes, and extensions can significantly enhance the machine’s versatility, making it suitable for a wider range of tasks. Investing in a unit that comes with these extras can save you time and money in the long run.
