Pressure Washer Buying Guide: How to Choose the Right Model

Your patio has turned a dull grey, the car is unrecognisable after a weekend in the country, and your garden furniture is looking worse for wear. When faced with this reality, elbow grease and a sponge just won't cut it anymore. The pressure washer emerges as the secret weapon to breathe new life into your exteriors and vehicles, without sacrificing your entire weekend.

But faced with a jungle of models, how do you find your way? Should you opt for the raw power of a corded model or the freedom of a battery-powered device? Which accessories are true allies and which are just gadgets? Our mission as editors is simple: to clear the path for you, testing and analysing products to help you make the right choice, with complete objectivity and cutting through the marketing noise.

Buyer's Guide: The Criteria That Truly Matter for Your Pressure Washer

Before diving into our top picks, let's review the key points to find the model that will be a perfect match for you.

1. Power and Flow Rate: The Dynamic Duo

The performance of a pressure washer is measured by two inseparable criteria:

• Pressure (in bars): This is the striking power of your device. The higher it is, the more effective it will be at dislodging stubborn dirt from resistant surfaces (stone, concrete, etc.).
• Flow Rate (in litres per hour, L/h): This is the volume of water projected. A high flow rate means faster cleaning: you'll cover more surface area in less time.

To strip a patio or a fa?ade, a robust corded model with a pressure of 140 to 180 bars and a flow rate exceeding 450 L/h is a must. However, for washing a car or smaller areas, a cordless pressure washer (often called a battery-powered wash gun) with adjustable pressure will prove more than sufficient and far more manageable.

2. Accessories: The Real Game-Changers

A good pressure washer is nice. A well-equipped pressure washer is better! Accessories transform it into a true Swiss Army knife of cleaning. Here are the essentials:

• The Turbo Nozzle (or Rotary Nozzle): It combines the power of a pinpoint jet with wide coverage. Perfect for truly grimy floors.
• The Car Wash Gun: Its spray is wider and less aggressive, for cleaning the car body without risking damage.
• The Foam Cannon: The best friend of car detailing enthusiasts. It covers the vehicle in a thick foam that gently works to lift dirt before washing. It's the star car washing accessory of the moment.
• Brushes: Practical for tackling dirt on wheel rims or garden furniture.

A word of advice: before you buy, take a close look at the included accessories. They should match your intended use.

3. Ergonomics and Ease of Use

Power isn't everything. Consider the practical side: the machine's weight, the length of the high-pressure hose and power cord, the presence of wheels or a hose reel... A compact and lightweight model will be a breeze to store and take out, while a hose of 8 metres or more will save you from having to move the unit every five minutes.

Frequently Asked Questions about Pressure Washers

1. What pressure should I use to clean a wooden deck without damaging it?

For a wooden deck, moderation is key. Opt for a pressure around 100 to 120 bars and use a fan-spray nozzle, never the turbo nozzle, which could gouge and damage the wood fibres. Our advice: always start with the lowest pressure setting at a safe distance (about 30 cm), then gradually increase if necessary.

2. Can I use any type of detergent?

Absolutely not! It is crucial to use detergents specifically formulated for pressure washers. These products are designed to be effective even at low pressure and, most importantly, not to damage your machine's internal components (pump, seals...). Using unsuitable products like pure bleach can cause irreversible damage to both the device and the surface you are cleaning.

3. How do I properly winterise my pressure washer?

To prevent frost from destroying your device, purging it is a non-negotiable step before winter storage. Completely drain the water by running the machine for a few seconds while empty (not connected to a water supply). For maximum protection, you can inject a specific antifreeze fluid. Then, store the device and its accessories in a dry, and above all, frost-free place.
