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 roll up or unroll when finished. To the front are holding parts 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.

The Karcher K7 pressure washer has an in-built water cooling mechanism that cools the motor. Before the water pumps out of the machine, it flows through a network of pipes around the motor to keep it perfectly cool. To test the product we started with the garden pavement which was very long as it wound around the entire house. The results were just excellent; the entire pavement was cleaned just in one round and was shining like anything.

The washer comes with a much more powerful T450 patio cleaner. This is perfect for bringing your patio up like new. The patio jet has an extra flat nozzle which helps get rid of the dirt from the corners and the places that are difficult to clean. The pressure washer has an additional detergent regulator switch for controlling the quantity of detergent being used. The regulator dial can be set to minimum or maximum as required depending on how you are using it. There are handles on the unit which allow you to wash vertical surfaces, which is great for cleaning your garage for example.

The environment-friendly washer saves almost 20% of the water and power. It judiciously uses water and prevents any kind of waste. Even the body of the pressure washer is made up of recyclable material. To initiate an eco-friendly cleaning just twist the switch to the eco sign and automatically the device regulates the water and electricity consumption.

The pressure washer is easy to use and move. It is operated in an upright position making it easy to grip and move across to different places. To increase the coverage area of the washer it comes with a 10m long hose. This hose is wound over the in-built reel under the handle. The Karcher K7 Premium Eco Home pressure washer reel helps to wound the hose neatly.

There are specific slots to store the gun and accessories directly in the washer thus making it easy to store and organise. The pressure washer is electrically safe as the switches have a rubber coating and also the wheels are rubber coated for safe and smooth mobility. It is a heft bit of kit and the twin wheels make it easy to move around like a suitcase, also the weight ensures that it won’t easily fall over.

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 is the previous version is the LED display; it requires 2 AAA batteries that come with it to power. 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 peace of mind when investing in this.
