10 reviews for Kärcher K 4 Power Control high pressure washer: Intelligent app support – the right solution for heavier soiling

  1. Moomin mama

    Fantastic cleaningThis washer was very easy to assemble and the app leads you through it all step by step. I was up and running in less than 30 mins. I’mnot normally one for apps, but this one was actually really useful. It also provides step by step instructions for each type of cleaning and tells you which attachments and key strength to use.The machine is very easy to use and it’s simple to change attachments. I used the patio cleaner attachment which was fantastic and took off years of lichen, moss and dirt in seconds with no scrubbing needed. It really was so easy. My patio looks amazing. The specific patio attachment was well worth it, although just the normal jet would have also done the job it would have taken a long time to do the large area.Haven’t yet used the car attachment but looks very easy also and am sure it will also give great results.As previous reviews take care in worn areas, the pressure was so high it took out some (already damaged) grout between flagstones but I was expecting this and it’s no drama to repair, my patio still looks better.Seems solidly built and is easy to move. Whilst it’s heavy it’s not unmanageable. The wheels and telescopic handle are good features. Storage net is a little too small to hold the power cable but that’s the only negative I can find.Definitely worth the money

    Good would recommend.I’ve had a couple of good pressure washers. This is as good as any. Recommend.Pull up handle is a bit flimsy but good enough.Powerful with a selection of heads. Tried it with the rotator on an old garden chair as an experiment. Tore the fabric.Quite a bit of assembly required. Straightforward though.USE THE APP FOR ASSEMBLY much clearer. The instruction book is next to useless and the PDF is just the instruction book.Pipe is stiff and inflexible. It would be better if rubber and flexible.

    Cleaning out doorsThis product was bought to clean an out door kitchen and patio including brick walls all were green and moseyThe K4 made easy work of the cleaning with the addition of the patio cleaner it’s was just brilliantlThe k4 gives you full power control which makes light work of even the dirtiest spots and when you have finished it’s packs up mice and neatHighly recommended

    Easy to useHave had other Karcher machines and this is another winner, very easy to use, not the lightest but seems very robust. Instructions for assembly aren’t the clearest as whoever put this together assumed that you have 20/20 vision, its the part where having pushed the wheels on you then lock them in place with the two slightly longer screws. Clear instructions on which attachments and pressure level to use.

    BrilliantI have used the kartcher on my decking and patio with the round attachment. Fantastic results. Great for washing the car, I can’t fault it. Great buy all round.

  6. Peter Jersey

    The car kit makes cleaning the car so much easierThe cleaner fluid is good and made my car look like new again. I haven’t used the patio cleaner yet but I have my fingers crossed I get similar results. The unit doesn’t take up too much room either.

    Brilliant replacement for my not so powerful k2 pressure washerHard to assemble, easy to use and setup once assembled, the hose and the wands and accessories are cheaply made, I can see them breaking or cracking with a lot of use, I’ve upgraded straight away to 1/4” quick connect trigger and lance using the Kärcher k series quick connect, I’ve just purchased a anti kink rubber reinforced 10 meter high pressure hose with Kärcher connectors online from a reputable manufacturer in the UK who do them specially for car detailing and commercial environments, the hose has linked several times winding it in.As for rest of the accessories and Kärcher shampoos I will not be using them on my car or patio as I don’t want to damage my paintwork or my brick work with something that doesn’t tell you what it contains. I just don’t want to run the risk.I will use them for bicycles and scooters and outdoor toys and areas that’s not visible all year round.As for power it’s very powerful and does the job no chemicals needed, makes my k2 look like it’s been used daily for 20 years it’s that powerful. 130 bar is enough to clean a patio and car without damaging it set to the right setting.

    Das Gerät hat einen englischen Stecker.Leider war diese Information für mich aus der Beschreibung nicht ersichtlich. Nun muss ich einen Adapter besorgen, um das Gerät nutzen zu können. Sehr ärgerlich!


    Nettoyeur Haute PressionLe nettoyeur doit être assemblé par nos soins et une application téléphone permet de le faire aisément. Un petit bémol : la prise d’alimentation au secteur nécessite l’achat d’un adaptateur universel car non compatible avec le réseau en France. Je suis surpris car l’appareil est fabriqué en Europe. Coût supplémentaire : environ 10 euros.
