This thing is a beast! We had a Karcher a few years back and I thought that one was powerful but this one puts it to shame. Power with a capital P. Mostly using on the patio slabs and dark bit up the side of the house that is always dark green but it’s great for the guttering on the conservatory too. Have been standing quite a distance away on the garden incline and just aiming in the general direction of the gutters because I’m terrified of it being on the wrong setting and punching a hole right through the glass roof by mistake. So far, so good though. Makes light work of everything we’ve tried it on and I’m delighted with the results. I usually hate on principle anything that comes with an app or needs one to integrate or work with but I’ll make an exception for this one because it’s a great bit of kit.

Packaged and presented with a high quality solid craftsmanship and setup is a breeze. I am particularly pleased how well made this one is thanks to the shape and design. Also this model is compatible with an app which is user friendly and gives an insightful application advisor, which will give you the best advice on for example cleaning a car and what pressure level to use, also the nozzle setting and instruction step which is reasonably good and optional / useful if your new to pressure washers.

In terms of performance i think it works quicker and more effective then some of tried in the past. Whizzes through effectively particularly a patio and after a few minutes i noticed how it wants to attack the job at hand and basically does all the hard work. It really does pack a punch with absolutely no issues whatsoever.
Once you get used to the nozzle settings switching relating to the job, then you know the effectiveness and capabilities where you will notice the difference.

Its durable and has a strong handle to transport easily from area to area. Little weighty but sufficient cable length does make life alot easier and convenient.
Im not keen on the trigger, it does go in too easily, so when you get a tired hand i found it will ease off the trigger and go off, but no biggy!

Care and maintenance instructions are straight forward and to be fair im really impressed with this machine.

Pros — Powerful
Solid Build Quality
Great Results

Cons — Expensive
Heavy
Pointless app

Very happy to recommend though as it surpassed expectations.

This power washer comes in a large box that contains everything you need to get started. The boxers filled with information both the power washer and how it can be used effectively all of its features.

Once you remove the power washer from the box it is two assemble everything together and get it ready for use. The power washer is a smartwatcher so it can also be connected to your phone making it very convenient and easy to use.

Once is connected to your phone you are able to choose different surfaces that you would be washing and it will automatically adjust the power of the water to match the surface you are cleaning. This can also be done manually if you would prefer to do it that way. It’s great for quickly switching between different surfaces and making sure that your cause no damage as the jet is extremely strong on some modes. It will be perfect in the summer for keeping garden tiles clean.

As compared to my old K5 pressure washer this K7 is more powerful. As Karcher is known for it’s build quality and long life products, The build quality of this pressure washer is exceptional. The robust construction and quality materials used instil confidence in its durability. The design is not only sturdy but also practical, with a convenient hose reel, telescopic handle, and large wheels for easy manoeuvrability. These features make it a joy to use, even for extended cleaning sessions.
Best thing that this comes with hose wheel which make it easier to sort after use. Noise levels are relatively low compared to other pressure washers in its class. This doesn’t come with car and home kit but I can still use my old K5 car and home kit with this K7. Overall a great machine for those looking for a powerful pressure washer.

I just pressure washed my patio and garden path in about half the time it took with my old machine. And it has done a better job. The twirly thing is particularly effective. I love that I can clean up to the edge of my patio slabs without sending the pea shingle from around the house all over the place. And I love that it is quieter so I don’t feel quite as guilty for disturbing the neighbours.
Definitely worth 5 stars, but there are a couple of points to be aware of about the app and the instruction book. The instruction book is thin and poorly laid out. The diagram of parts is on page 2, and the key naming the parts is on page 9, which I find very irritating. The phone app seems to be in lieu of a decent manual and to follow it’s step by step instructions you need to have your phone in your hand as you set up or change the settings. When I do anything with a pressure washer there is usually water everywhere and my hands are wet; not the environment I want to expose my phone to. However, having been through all of that I find that it is actually pretty intuitive to use, and would have been much simpler if I had just abandoned the phone app after registering.
You need the app to register the product, but after that it seems to be information only. As app and pressure washer connect by blue tooth I had wondered if the app affected the settings in any way; it doesn’t, so from now on my phone can stay in the house while I’m pressure washing.
Overall I’m really impressed with it. Doing the back garden used to be an exhausting days work. Now its 2 hours including cleaning up and putting away, and its a piece of cake.
