Comparison of high-pressure cleaners
First impression / accessories
At first glance, the pressure washer makes one sturdy and stable impression. The device with dimensions of approx. 34 x 28 x 68 cm and a weight of 8 kg also makes a clear appearance. The scope of delivery consists of the device itself three different essays for different surfaces. In addition to the pressure gun itself for large and large-scale work, there is also a brush for fine tiles and fine substrates and a smaller gun for smaller cleanings, for example on bicycles.
The Kärcher high-pressure cleaner K3 can be bought with an extra winding roll for the power cable, but in my test I used one without, since there is already a roll-up option on the side from the factory.
The operation of the high-pressure cleaner consists only of a water connection and a switch-on button. The pressure gun also has the option of adjusting the pressure individually Adjust the grill yourself to be able to.
There is a large holder for the pressure gun, the other two attachments can also be hung in a device. However, I find this to be very shaky and unstable. During assembly, the brush kept falling out, so I initially put the two attachments that I don't use to one side.
The high-pressure cleaner K3 has a tank for cleaning supplies. This must be filled before the first use. The cleaning agent is not included in the scope of delivery and must be purchased separately from around €8.
Sometimes it can happen that the ½ inch connection does not fit, so you should check in advance whether an adapter might be needed.
Possibilities with the Kärcher high-pressure cleaner K3
The Kärcher high-pressure cleaner K3 offers one Variety of possible uses and can be used for different purposes.
The jet pipe itself has an adjustment option for the water pressure. This can be between 0 and 120 bar be regulated manually directly on the handle. The current water pressure is displayed visually using LED technology.
Kärcher itself offers one for the K3 model App at. This offers an all-round service including information about the device, the application and the Kärcher service portal.
The built-in cleaning tank allows you to switch between using the high-pressure function and the cleaning function. You do not need to change the jet tube for this. For example, a motorcycle can first be lathered and cleaned and then rinsed clear.
Different substrates and surfaces can be processed with the different attachments. The classic spray lance delivers the maximum water pressure and is suitable for larger or heavily soiled surfaces. This also includes paving stones and walls. The smaller gun can be used for smaller, finer jobs, such as cleaning Bicycles or Rims be used. for cleaning tiles, terrace slabs or similar sensitive surfaces, the attachment with the brush can be used. By rotating, it cleans gently and does not cause any damage.
The first use | Quality assessment
After I filled the cleaning agent tank with the appropriate liquid, connected the water hose and set the spray lance to medium strength, I was finally able to get started. I first worked on paving stones in the garden, as they are infested with green covering over the winter.
After switching on for the first test I have one right away strong water pressure felt. The pressure washer is however but quite loud, which seems understandable due to the enormous performance and the pressure to be formed.
In my opinion, the jet pipe is very well made, the water jet is focused on one point on the ground, creating a great cleaning is made possible. I was able to clean the stones from plaque in a pleasant way. Now I have changed the jet strength, which is actually possible directly on the handle. But for stubborn dirt on the stones, I also had to activate the highest level. I also noticed that the spray lance could be a little longer, since longer work is quickly on your back.
What I noticed during the test is that the water sprayed heavily in all directions and thus also Walls and windows soiled. There is a so-called splash guard from Kärcher, but this has to be bought separately.
Next I have mine Bicycle cleaned. I used the smaller pistol for this. For this cleaning, I first used the cleaning agent and then rinsed it clear with water. The dirt was easy to remove, even if it wasn't too stubborn.
Overall, the Kärcher high-pressure cleaner K3 delivered a great result, stones and walls were sprayed very clean.
The App I've looked at it, but I couldn't find any added value.
