Selecting the appropriate settings is key for optimal results. For light tasks like rinsing cars or watering plants, use the lower settings to gently remove dirt without causing damage. For medium tasks, such as cleaning patio furniture or bikes, adjust to a mid-range level for enhanced effectiveness.
Low Pressure
This setting is ideal for delicate surfaces. Aim for a pressure of around 100 bar to ensure thorough rinsing without risk of harming the finish. It’s perfect for tasks where stubborn grime isn’t a concern, allowing for safe and efficient cleaning.
Medium Pressure
At approximately 120-140 bar, this setting balances power and precision. It’s suitable for patios and driveways, where dirt accumulation occurs but surfaces need protection from potential damage. Test a small area first to ensure the setting is appropriate for your specific cleaning needs.
Experimenting with these pressure options can lead to superior cleaning outcomes. Save time and avoid wear on your surfaces by using the correct settings tailored to your cleaning tasks.
Choosing the right nozzle for your cleaning task
Select a nozzle based on the surface and level of grime. For delicate surfaces like cars and patio furniture, opt for a wider spray pattern. The 25-degree fan nozzle is ideal for light cleaning without risking damage. For stubborn dirt on driveways or patios, a narrow spray can tackle tough stains effectively. The 15-degree nozzle concentrates power onto a smaller area, making it suitable for these surfaces.
Orbital nozzles
If your equipment supports it, consider using an orbital attachment. This feature combines rotational motion with linear pressure, allowing for rapid and thorough dirt removal without excessive force. It works wonders on surfaces such as decks and fences, reducing the risk of streaks or damage.
Specialty nozzles
For specialised tasks, such as removing paint or heavy grease, use the turbo nozzle. This attachment generates a spinning jet that maximises cleaning effectiveness. Pairing it with the right detergent can yield impressive results on particularly challenging jobs.
Always consult the user manual to ensure compatibility and follow safety instructions to avoid injuries or equipment damage. A simple change of nozzle can dramatically improve results and efficiency in all your cleaning projects.
Connecting the Water Supply and Power Source
