Pressure Washers Buying Guide
Expert Buying Tips on How To Choose the Best Model

Pressure washers are highly efficient pieces of cleaning equipment which can clear away stubborn dirt using a fraction of the time, water consumption, and effort hand cleaning takes.

The most common uses for pressure washers are cleaning cars, patios, decking and garden furniture.

How does a pressure washer work?

Pressure washers have a motor which is powered by either mains electric, a petrol engine or a battery. This then powers a pump which pressurises the water, so when the lance is depressed, the pressure is released. Three factors define the power of each model, the pressure of the water expelled (measured in bar or Pounds Per Square Inch PSI), the rate of water flow (measured in litres per hour L/h) and motor power (measured in watts, or horsepower if petrol/diesel operated).

What size pressure washer do I need?

Pressure washers are usually defined by their application and can differ greatly, but each type is fit for purpose. Choose a pressure washer with the right balance of pressure and flow rate for your needs.

Electric vs. Petrol Pressure Washers

Electric Pressure Washers

The majority of pressure washers are electric powered so make sure your power socket or outdoor extension lead is protected by a residual current device (RCD).
Battery-powered models, on the other hand, offer greater portability and are ideal for light-duty cleaning.

Pros:

• More affordable than petrol models
• Quieter and cleaner
• Easy to start with a switch
• Lightweight
• Low maintenance

Considerations:

• Corded models limit mobility
• Less powerful than petrol models

Electric vs. Petrol Pressure Washers

Petrol Pressure Washer

Petrol or diesel-powered pressure washers are ideal if you have no access to a power supply. They also tend to be higher powered and remove the risk from trailing power cables.

Pros:

• Ideal for large areas and tough jobs
• Cord-free for better mobility
• Some models offer push-button start

Considerations

• Most models have a manual pull start
• Require more maintenance
• Need fuel on hand to run
• Petrol/Diesel pressure washers can be more expensive

Hot vs. Cold Pressure Washers

Hot Pressure Washers

Adding heat helps loosen dirt, grease, and oil more easily. As a result, hot pressure washers require less pressure and detergent, making them a more hygienic option. Some models, like ours PW2500HW, can reach sterilizing temperatures up to 90°C.

They are...

• Bulkier than cold pressure washers due to the built-in boiler required to heat the water
• Typically more expensive
• Better suited for cold-weather climates where water lines may freeze
• Some models meet sanitation standards for food processing, making them ideal for certain food service applications

Hot vs. Cold Pressure Washers

Cold Pressure Washers

Cold pressure washers are commonly used cleaning tools that spray water at high pressure to remove dirt. Many models like PW2400 also use detergent to tackle stains and grime, ensuring thorough cleaning.

They are...

• Ideal for large areas
• More affordable
• Low maintenance
• Safer for surfaces like wood or plastic that can warp with heat

Can you use hot water in a cold-water pressure washer?

You can safely run warm water (up to 150°F / 65°C) through a cold-water pressure washer. However, using hot water—especially at high temperatures—can damage the pump seals and overheat the unit. Plus, most hot water tanks can’t keep up with the demand for long.

Which pressure washer is right for me?

Choosing the right pressure washer depends on what you’re cleaning and how often. Higher pressure is best for tough grime and hard surfaces, while high flow helps with rinsing. For versatility, look for models with variable pressure or soft-cleaning modes like the PWTF2200.

It is also useful to consider the following features when selecting your pressure washer:

Hose Length

Check the length supplied with the pressure washer is suitable for the jobs you’ll be tackling most often.

Integrated Storage

Not only will it keep the unit clutter-free, it improves mobility and ensures accessories are always at hand.

Automatic Total Stop System (TSS)

This switches the motor on and off when the trigger is operated, prolonging motor life.

Detergent Tanks & Systems

Using the right detergent makes cleaning faster and more effective. The PW1860COMBO includes a snow foam sprayer that works with our pH-neutral, non-wax-stripping shampoo to break down dirt and rinse off easily for a streak-free finish.

Hose Length

Different nozzles offer varying spray patterns and pressure for specific tasks. Models like PWM2500 & PWM2500SP come with interchangeable options:

• 0° (Red): Most powerful, for tough stains
• 15° (Yellow): Heavy-duty cleaning
• 25° (Green): General cleaning
• 40° (White): Gentle cleaning (cars, furniture)
• 65° (Black): Low pressure, for soap application

To make the most of your pressure washer, look for accessories designed to help with different cleaning tasks.
