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, Home 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.
Recently the Eco models have been discounted, although can still be bought online, with the new Full Control range you can choose between the home and premium packages. The spec of the pressure washer remains the same, however the attachments that come with it 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. The differences are in the casing and design, that compact K2 is what it says, more compact, it is designed to be as small as possible and easy to carry. Where as the K2 Home and Premium models have wheels and an extended handle to allow you to pull the pressure washer around like a suitcase.
If you live in a flat, or have limited storage space then the K2 Compact is a great choice.
