Pressure Washer Buying Guide

Investing into the best pressure washer you can buy that is within your budget can be very beneficial. Trying to scrub tough dirt, grime and other debris from your wall, floor, patio or car can get your nowhere sometimes. All of our recommendations above are suited for a range of price brackets and from the best brands.

To help you make an informed buying decision, we have produced the below guide regarding pressure washers.

Gas vs Electric Powered

You will notice that the majority of pressure washers available in the UK are electric powered. This is mainly due to the fact that the electric motors have improved massively, which allows you to tackle tough dirt with ease.

In terms of the power differences, the majority of electric motors will be able to deliver 2,000 PSI. However, for jobs that require further pressure, the gas powered alternative will be capable of producing over 7,000 PSI of pressure.

Gas pressure washers do have their uses and work great for tough jobs where an outlet is not accessible. However, unless you are able to reduce the power output, they would not be suitable for car valeting. Using too much pressure can result in paint removal, which would be an expensive repair.

The best pressure washer type is definitely the electric powered units. They are lighter, easier to use, cheaper, require no servicing or fuel and are safe for cars, patio and other common cleaning tasks.

Compatibility With Different Attachments

Certain cleaning tasks can be made even easier by using a pressure washer attachment. The most popular being a snow foam lance, which allows you to spray the car with thick foam before using a wash mitt. Other attachments include a patio cleaner, splash guard, telescoping handles and much more.

Some units may not be compatible with other attachments, which can be very frustrating. However, by sticking to reputable brands such as the units listed above, you will have access to a range of different attachments.

Water Usage – Measured in l/h

For those that are on a water meter and want to keep the usage to a minimum, you will want an efficient unit. You are able to determine which uses the least amount of water by analysing the water flow rating.

The higher the water flow rating of a pressure washer will result in more water output from the nozzle. The benefit of a higher rating is that you will be able to wash the car quicker but it does mean that you are using extra water.

Size, Weight and Portability

For the more powerful pressure washers, you will often have a much larger unit. This is due to the powerful motor that outputs more water at a greater pressure. If you are planning on transporting the pressure washer from job to job, a more compact unit would be the best option.

Other factors that improve the portability include integrated wheels and ergonomic handle for carrying or pulling. Apart from the Bosch unit, all of the recommendations have both wheels and handles for easy transportation. Due to the size of the Bosch alternative, it is lightweight enough to carry around.

The Handle

Over the years, the pressure washer handle has become more advanced than ever. The Karcher models listed above even have a LED display integrated into them so that outputs real time data.

Other desirable handle features include an ergonomic grip that is non-slip, telescoping functionality and ease of connecting attachments.

Hose Length

One factor that is often forgotten about is the length of the hose. It can become fairly frustrating having to constantly move the pressure washer around due to the hose not being long enough. We would highly recommend anything between 5 and 10 metres in length.

Pressure Rating

Pressure is measured in either “bar” or “PSI” and is the force at which water is pumped out. Electric units can often output up to 150 bar of pressure whereas gas powered alternatives can double the output.

For car valeting and other light tasks, 110 to 120 bar is more than ideal. However, for patio cleaning, we would recommend a more powerful unit of 130 bar and over.

Nozzle Spray Patterns

When setting up your pressure washer, you will want to the correct spray pattern for the best results. Most units come with an adjustable nozzle but others may come with specific nozzles that you must install.

Depending upon the type of cleaning you are doing will determine the spray pattern that you require. For example, a narrow spray pattern will allow you to be more precise and apply all the pressure to that specific area.

However, this can be fairly risky for some cleaning tasks such as car valeting. For this you will want a wider spray nozzle setting to avoid any damage to the paintwork.

The Motor and Pump

There are three different types of motors that are found in pressure washers. These include a universal, induction and water-cooled motor. Each have their own benefits in terms of performance and noise levels. In terms of the pumps inside the units, the most common are wobble, axial and triplex.


Investing into the best pressure washer you can get your hands on will make a huge difference to how you clean. They are expensive but when you consider that they can last many years and most come with long warranties. Sticking with the big brands such as Karcher, Bosch and Nilfisk will ensure that you are able to use a range of attachments.

Once you have got your pressure washer, we highly recommend reading the manual or following this guide to setting it up properly. Not every unit is assembled and it may not be as simple as plugging it in and you are up and running.
