🏆 Best for Remote Jobs

Kärcher K5 Power Control Flex Car & Home
🏆 Best Value Bundle
The full kit and caboodle for the homeowner who wants to clean everything from the car to the conservatory.
This bundle takes the excellent K5 and adds the T5 patio cleaner and car foam nozzle, saving you a fortune over buying them separately.
Reasons to buy

- ✓Includes specific detergents that actually work on UK road grime
- ✓Excellent value for money when you factor in the cost of the individual attachments

Ask the Community →How to Choose a Pressure Washer That Won't Let You Down
Buying a pressure washer is easy; buying one that still works in three years is the hard part. Here is what you actually need to look for.
Bar Pressure vs Flow Rate
Everyone looks at the Bar pressure, but the flow rate (litres per hour) is what actually moves the dirt away. A high-pressure stream that's as thin as a needle will take you all day to clean a single slab. Look for a balance; 130-145 Bar is plenty for most UK homes if the flow rate is at least 420L/h.
Hose Length and Quality
There is nothing more annoying than having to move the heavy base unit every two minutes because the hose is too short. Aim for at least 8 metres. Also, look for 'Flex' or 'Anti-twist' hoses. The standard plastic ones have a memory like an elephant and will stay coiled up, causing you to trip and swear in equal measure.
Motor Cooling
Cheaper units use air-cooled motors. They're fine for a quick 10-minute blast of the car, but if you're doing a whole driveway, they'll overheat. Water-cooled motors use the incoming water to keep the internals cool, meaning they can run for longer and last years longer.
Frequently Asked Questions
Can I use water from a water butt?
Yes, most of these units can draw from a butt, but you must use a suction hose with a proper filter. If you get a bit of grit or a dead slug in the pump, it's game over for your machine.
Why is my pressure washer pulsing?
It's usually a sign of a blockage in the nozzle or a leak in the hose. Check your connections first. If it's still doing it, your pump might be drawing in air, which is a one-way ticket to a broken unit if you don't fix it.
Do I really need the special detergents?
For cars, yes, as they help break down traffic film. For patios, a bit of elbow grease and the right nozzle usually do 90% of the work, but a dedicated stone cleaner can help prevent the moss from coming back quite so quickly.
