FAQ

What’s typically included in the box with a new pressure washer?

Most pressure washers come with a basic lance nozzle for concentrated cleaning, a wide-angle nozzle for covering larger areas and an extension wand to reach high or awkward spots. You'll usually also find a delivery hose and a power cable; however, some models omit accessories like a surface cleaner attachment.

I’ve noticed my pressure washer doesn’t have a foam cannon – what is this and why do I need one?

A foam cannon creates a luxurious cleaning foam by mixing detergent with water under high pressure, ideal for patios and driveways. They are typically purchased separately and add significantly to the cleaning process.

Are detergents specifically designed for pressure washers different from regular washing-up liquid?

Yes, using standard washing-up liquid can damage your pump and hoses due to its high alkalinity. Pressure washer detergents are formulated to be safe for these components and deliver optimal cleaning results.

What kind of nozzle attachments are useful beyond the basic lance and wide angle?

Consider a rotary nozzle for scrubbing stubborn stains, or a jetter nozzle for clearing blocked drains – these offer specialised cleaning capabilities not found on standard nozzles.

Do I need to invest in a surface cleaner attachment? Are they worth it?

Surface cleaners are designed to automatically clean patios and driveways with a rotating brush head, saving time and effort. They're particularly beneficial for larger areas and consistent cleaning patterns.

What about protecting my surfaces – do I need a special nozzle or attachment for delicate materials?

A brass nozzle is essential for preventing damage to painted walls, wood, and other delicate surfaces by reducing the pressure delivered. Soft wash attachments are also available to minimise impact.

I’ve heard about ‘dirty water inlets’. What are these and why do I need one?

'Dirty water inlets' – sometimes called 'bypass inlets' – allow dirty water from the spray to bypass the pump, preventing blockages caused by debris and prolonging pump life.

How often should I be replacing the filter in my pressure washer?

Filters trap dirt and debris before they reach the pump. Replacement frequency depends on usage but generally, it’s recommended to replace the filter every 10-20 hours of operation or at least annually.

What do I need to clean the spray gun nozzle?

The lance nozzle can become clogged with mineral deposits – you'll need a small nozzle cleaner (often included) or a pin to clear any blockages and maintain optimal water flow.

Are there any specific safety precautions I should be aware of when using accessories?

Always read the manufacturer’s instructions for each accessory and wear appropriate PPE, including gloves and eye protection. Adjusting pressure correctly is crucial to avoid damage or injury – start with a low setting.

In depth

A pressure washer’s primary function is cleaning, but achieving truly effective results often relies on more than just the machine itself. Alongside the unit itself, there are several accessories and consumables that significantly enhance its performance and longevity. Many buyers overlook these supplementary items when budgeting for a new pressure washer, leading to unexpected costs or compromised cleaning capabilities.

Firstly, consider the range of nozzles available. While most pressure washers come with a basic lance nozzle for targeted cleaning and a wide-angle fan nozzle for general surfaces, expanding this selection dramatically increases versatility. Nozzles designed specifically for removing stubborn stains like moss or algae, or those suitable for delicate materials such as car paint or patio stones, represent a worthwhile investment. These specialized nozzles often offer adjustable spray patterns, allowing users to tailor the pressure and coverage precisely to the task at hand.

Secondly, don’t underestimate the importance of surface preparation. Before using a pressure washer, it's beneficial to apply a suitable cleaning solution – a detergent specifically formulated for outdoor use is generally recommended. These detergents are designed to lift dirt and grime effectively, reducing the amount of time and pressure needed during the wash cycle. Furthermore, consider incorporating a surface cleaner additive into your water supply; these additives help to encapsulate debris, preventing it from being redeposited onto the cleaned surface – a crucial step for achieving a truly professional finish.

Then there’s the matter of protecting both the machine and the surfaces you're cleaning. A foam cannon attachment is incredibly useful for applying detergent evenly across large areas, creating a protective layer that minimizes water damage and maximizes cleaning effectiveness. Similarly, utilising a brush attachment – often available in various sizes and shapes – allows targeted cleaning around intricate details or heavily soiled areas, providing significantly better results than relying solely on the pressure washer’s spray alone.

Consumables are another vital consideration. The detergent cartridges themselves will require frequent replacement depending on usage frequency and soil levels. Similarly, nozzles wear down over time due to abrasion against surfaces; a supply of replacement nozzles is essential for maintaining optimal cleaning performance. Consider also the need for pipe cleaners or detailing brushes for reaching tight spaces and removing stubborn debris accumulated within the machine itself – regular maintenance helps prevent blockages and ensures efficient operation.

Finally, adequate drainage is often overlooked but vital for safety and convenience. A long hose with a suitable spray nozzle will allow you to direct the water away from buildings, patios, and other areas that could be damaged by excessive runoff. Investing in a robust drain filter is also recommended; this prevents debris from being sucked back into the pressure washer, protecting its internal components and reducing maintenance requirements. Properly addressing these supplementary needs alongside the core equipment ensures optimal performance and prolongs the lifespan of your pressure washer investment.
