Amazon blurb:
Kärcher K2 Home

The K2 Home is a small, lightweight and portable machine, used for cleaning exterior items including patios and decking, cars, bicycles and garden furniture. An upright design, wheels and a long handle makes this machine easy to use and to maneuver and the on-board storage solution means the trigger gun and accessories are stored neat and safely with the machine. A pressure switch control switches the motor on and off when the trigger gun is pressed and released, whilst an impact-resistant, recyclable plastic casing effectively prevents dirt particles from damaging the motor and pump. All Kärcher K2 Pressure Washers can also be used from a gravity fed harvested water source such as a water butt tap.

Vario Lance
Used in order to achieve variable pressure control from low-pressure to high-pressure jet by simply twisting the spray lance. It is connected onto the end of the trigger gun with its bayonet design.

Dirtblaster

A powerful rotary nozzle designed with a rotating pencil jet which can provide up to 50% greater cleaning power than a standard high pressure lance, meaning it could be useful for removing stubborn dirt on moss covered or weathered surfaces.

T50 Patio cleaner

Used for the splash-free cleaning of even surfaces such as patios & decking, provides increased cleaning power with two rotating flat jet nozzles.

Patio & Deck detergent pouch

500ml of detergent concentrate simply add water to make up 5 litres of patio & deck detergent, designed in a practical pouch for storing. For gently removing oil, grease, dirt which is caused by emissions, moss and soot from balconies and terraces made from wood and stone.

Mobile, lightweight & Powerful

The upright design is designed to aid a good working posture and mobility is made easy as it is designed with a high handle and wheels. It is designed with an Air-cooled 1400 watt motor which makes it powerful for its size.

On-board storage

Provides a storage solution for the Vario Lance, Dirtblaster and electrical cable on the machine itself.

Detergent suction tube

This particular model is designed with a detergent suction tube, which allows you to draw detergent from a container. The unit will draw the detergent through the unit when the product is drawing water at low pressure.

Automatic motor and water inlet feature

All Kärcher pressure washers are designed with an automatic stop/start motor so the unit isn't continuously flowing during your cleaning application. The inlet filter is already built in the unit, this filter prevents debris entering and damaging the pump.
