In Australia, water is a scarce commodity and in certain areas strong water restrictions currently apply. To encourage more people around Australia to clean smart, Kärcher conducted an experiment to test just how little water a Kärcher pressure washer actually uses when cleaning a standard size car compared to a garden hose.
A standard garden hose uses 25L of water per minute, while a Kärcher K4 Pressure Washer uses 7L per minute; but just how many litres do you save by switching over to Kärcher?
In Kärcher's experiment it took 2:40 minutes of pressure washer use to clean the car, meaning a total of 16.5 litres of water was used. If we used a garden hose for the same amount of time to clean the vehicle, a total of 66.5 litres would be used. So, by switching over to Kärcher, a total of 50 litres of water could be saved.
You may have also noticed in the video above that syphoned water out of a bucket instead of a mains tap. This is a simple process that can be done with any type of Kärcher's K3–K7 pressure washer range.
Many water restrictions guidelines state that a car can only be cleaned by using a pre-filled bucket of water, so by syphoning water out of a bucket you can still use your Kärcher pressure washer even if you are in an area affected by water restrictions.
In addition to using a bucket, all Kärcher pressure washers can also be used by syphoning water from rain water tanks, which is also allowed under water restriction rules. It's often as simple as just connecting your garden hose to the tank of the water tank. If your tank does not have a tap, you can also feed a suction hose into the top of your tank and use the pressure washer as you would by syphoning water out of a bucket.
To operate a pressure washer using this technique is simple, all you need is a bucket of water and a suction hose.
