What are the differences between the Premium & Compact models?
Depending on which model you are looking at they all have the same spec, for example it you were looking at getting the K5 Pressure washer, there is no difference in terms of performance weather you go for the home, premium or compact, they all have a 2100 watt motor, giving 145 bar pressure, they all come with a 8m hose and have a flow rate of 500 litres per minute. So the internal power and pressure is the same which ever model you go for.
The differences are in how it is housed and how it is from the outside. There premium model has on board storage for attachments as well as a place to store and hold the trigger gun. On the premium model there is also a hose reel on the back for the lengthy 8m high pressure hose. With all this extra weight the design is very robust, it has large wheels to make it easy to move, however it is heaveir and bulkier than the compact for instance. The compact version is just that, more compact, there is no on board storage or a hose reel built in, it is designed to make the main unit as small as possible while still packing the powerful punch inside. Although the compact is smaller in size you still need to also store the hose and attachments somewhere else. With it being smaller it is also lighter making it easier to move and carry if needed.
Compact, eco and premium
K2, K4, K5 and K7; each comes with different packages – compact, eco and premium. K2 is air cooled while K4, K5 and K7 are water cooled. Also the number of accessories that come with each model may differ.
All models are robust and easy to use, setting up and for the first time and using it to clean your car. All models are good enough for cleaning down patio furniture, bike or car, however if you plan to use it more regularly then do look for a more powerful model. If you want to use a pressure washer for your patio and driveway then do look t models from the K4, K5 range, as these pack a bigger punch and will make a huge difference to the entry level K2.
Choose the appliances according to the work to be employed in for the best results. Do not fear spending when the premium version is needed.
What is the difference between Karcher K2 and K2 compact?
The specification of the K2 is the same throughout, the pressure is still 110 bar with a 1400 watt motor that is air-cooled.

In 2015 Karcher started rolling out a new update to its range of pressure washers which are titled under the ‘Full Control’ umbrella. Any model which includes this will include the new LED display trigger gun, this new design is to help guide you to the correct pressure setting for the surface you are trying to clean. It makes it easy to know which pressure setting to be on, you will want to be on max power for cleaning your patio removing dirt and grim that has been there for years, however while cleaning you car you will want to reduce this pressure as your may otherwise damage your car paintwork, so with the new trigger gun you can easily adjust this down to the desired setting.
