The K7 is very easy to put together out of the box taking just a few minutes, as with all Karcher pressure washers the attachments all click and connect together and then it is ready to use. There is a telescopic aluminium handle making this robust device easy to move around, weighing 18kg this is a solid and weighty bit of kit that won’t be easily knocked over.

On the back of the K7 is a hose reel which will hold the 10m long high pressure hose when not in use, it is easy to quickly pull out or wind back in when finished. To the front are holding part for the lances and trigger guns, allowing you to hold them there when not in use or when you have finished and are packing away. There are two large and robust wheels on the pressure washer making it easy to move around, as well as the telescopic handle there is also a handle grip at the front to the base too for lifting. At the front is also the on/off switch which is very solid and of high quality, reflecting the overall build quality.

LED display trigger gun – With all new Karcher pressure washers that are now ‘Full Control’ they come with a new trigger gun. The difference with this one of the previous version is the LED display, it requires 2 AAA batteries that come with it to power this. The display shows what setting you are on and what it is best suited for. On the display you will find an image of a fence, car and brickwork, for soft, medium and heavy use.

Plug’n’Clean Detergent System – With just one simple movement you can drop in your detergent bottle and you are ready to go, no need to fiddle around with tubes and settings, just drop it in and off you go.

Warranty – This premium K7 version has a 5 year warranty giving piece of mind when investing in this.


With the 160 bar pressure the K7 is the pressure washer of choice for the toughest of jobs, the power makes cleaning patios and driveways easy and with a water flow of 600 l/h it is extremely quick too. This model will allow you to clean up to 60 square metres an hour. The motor is water cooled using Karchers patented cooling system helping to reduce wear and increasing the lifetime of the machine.
