Karcher seems to be on the case
You are right Diesel Man, I guess the problem is every time it rains on my car it looks dirty!
Anyway I am now tempted to get a pressure washer. Just phoned up Karcher and you can get a "suction kit" which filters the water and can be put in a water butt or bucket - Cost £39.99.
Also according to their site you save water!
Karcher have this on their site.
Save Water
With a hot summer just around the corner it is likely that many areas of the UK will be subject to a hosepipe ban. High pressure cleaners are up to 90% more efficient than a garden hose, read our Q&A below to find out how to reduce your water consumption:
Q: How much water does a high pressure cleaner use?
A: A high pressure cleaner will use between 400 to 600 litres of water per hour. A saving of up to 90% when compared to a garden hose which uses up to 3500 litres per hour.
Q: How else does a high pressure cleaner save water?
A: Kärcher high pressure cleaners are all fitted with an auto-stop facility, when the trigger gun is released the machines pump automatically cuts out and stops the water flow. Saving both water, electricity and prolonging the life of your machine.
Q: Can I still use my high pressure cleaner during a hose pipe ban?
A: By connecting your high pressure cleaner to a hose pipe you will be contravening the water authorities advice. However, certain Kärcher pressure washers can be used without being connected to a hose pipe. With a suction kit accessory it is possible to draw water from a water butt, bucket or static water source. The suction kit is also fitted with a filter to remove any unwanted particles.
Q: Does my high pressure cleaner save water by cleaning more quickly?
A: Yes, because water is applied at high pressure, cleaning tasks are carried out quicker than other conventional methods. Saving you both time and water.
