Karcher K7 Premium Smart Control Pressure Washer

I thought my K4 was powerful but this blows it away. I can clean my front yard in 10 minutes with this whereas the K4 took an hour. You think the floor is clean, but then go over it with the brush attachment and you will be amazed how clean it becomes.

Wow this machine has it all. Powerful and Versatile 😘

Bought the K7 to replace a non-branded pressure washer then I ended up returning after a few weeks (hose wouldn't connect to the gun anymore). Was struggling to decide between the K4 and the K7 mostly due to cost, but decided the K7 would be best in the long run after getting a quote for someone to pressure wash my patio and drive. Was easy to put together, most of it is already connected, the hose wheel is brilliant for keeping the hose neatly stored, there's little clips to hold the gun and the lance extender which is a definite plus. Its missing a place to hold the electric cable when it's not in use but the handles work well for that. The handles though seem to instantly drop as soon as you let go of them, would of been good if they locked whilst they were extended. The machine itself is massive, much bigger than I expected, its a pain to lift up but comes with some sturdy wheels and a handle to help move it around. On the plus side, the size and weight does mean it doesn't move when your washing something unless you yank incredibly hard on the hose, it's going to stay where you put it. This has been handy for washing the car, no more fear of the machine running into the back of the car whilst I'm spraying down the front. Pressure seems fantastic, only used it on 2 - high setting so far but was a breeze to clean the car especially as the nozzle goes quite wide allowing you to cover more in less time. I borrowed the Karcher snow foam attachment to test with my new machine but quickly went back to my old 1L snow foam attachment as it stores enough to cover the entire car and can be adjusted more (the Karcher one is a bit disappointing). The app is terrible, once I set it up and followed the apps instructions for setup I did everything via the machine instead, not sure the app is worth anything though the guides for how to use the machine are more helpful than the printed instructions you get. The gun display is easy enough to use with a plus and minus button that it would be much more tenious to grab your phone and switch the settings via that. All in all, an excellent pressure washer, if your on the fence would definitely recommend it despite the price it seems a solid piece of equipment.

Yes, you've got it in one.......... a blocked sewer pipe! I new our near twenty year old budget Karcher stood no chance, especially as it required a massive bash to get it to work at all so, it was time to invest in a new machine and, as all the you tube videos imied 180 bar was the way to go, the K7 was the machine for me. It arrived today. The Amazon app saying before ten p.m. and it was.... 8 a.m! Go Amazon and DPD, that was amzing! Now, my lad gave me strict instructions (as he was getting in the car and dissappearing) that I had to use his drain rods first or the blockage would become compacted. So, the only way to access our sewer pipe without actually digging down to it, is via the soil stack (now I know why he did a runner!) ........ up the ladders and started feeding the rods down. As soon as the spirally end hit the bend at the bottom, it stuck! Wouldn't go down or back up. Much sweating and cursing later, I got the rods free, chucked them up the garden and got the K7 set up, with a drain cleaning attachment ( 5mtrs shorter and ten quid cheaper than the genuine Karcher one but, this has an end with a forward facing jet as well as the rear jets) and fed the pipe down, jetting as it went no problems getting round the bend at the soil stack base, and into the blockage. Using a push in pull back action, the blockage was defeated I about 20 minutes - it is true that the gurgle of the blockage freeing up is one of life's most satisfying sounds. Soil stack back together, it was time to clean up the overspill so, the included patio cleaning attachment came out, and in no time, everything was sparkly clean. The Karcher proved more than a match for this tricky job and I reckon it has paid for itself already, especially as I took advantage of the Amazon Day sale and got it for much cheaper than it is now! My lad is impressed with the K7 and has lined up a few jobs for it already (he can do those jobs, he's not getting out of it again). All in all, I'm delighted with the Karcher K7 and may even start cleaning my car again!

I bought this to replace a very old karcher (520M) that I owned for 20 odd years that eventually failed me. It was a shame as the main pump was made from metal - maybe that was the reason for its longevity. In buying the K7, I was after an upgrade to the pressure as well as a longer pressure line that would at last allow me spend less time manoeuvring the machine when washing cars and the patio. The K7 came almost completely assembled bar some netting that retains the power cable - it's a 2 minute job and didn't bother me. I believe other Karchers require more assembly for some reason. The Excellent The machine is very powerful and the lance allows you to fine tune the power very easily - especially when washing the car where you need flexibility and getting extra grunt on the patio. The power cable they give you is 5 metres and long enough for flexibility and to ensure that it is plugged in well away from outlets - this was always a concern on my previous Karcher. The pressure cable is 10 metres - great for getting around the car. Well nearly.... more later.. The T7 Surface Cleaner is in my view the best feature. It is absolutely fantastic and will cut your patio cleaning time down by 90% - and also the clean up afterwards including not having wet shoes and clothes and detritus all over the place. I find that I clean the patio as frequently as the car, it is that easy. The Frustrating There is one element where I find the machine lets itself down and that is the pressure hose itself. My old Karcher's hose was much thicker and very rarely kinked and got caught. This is just an absolute nightmare. It doesn't kink as such but frequently coils itself in small loops meaning that you have to spend time trying to uncoil it. It means that 9 times out of 10, you wont be able to get round your car as the loops have reduced the working length by at least half. It also means that when you coil it up again, you have to take the lance off in case it breaks (more later). There are some choice words when coiling it back up. The Not so Sure To control the pressure, the lance has a small screen and buttons where your instructions are sent to the machine over bluetooth. The lance, therefore, has a an embedded bluetooth module, a screen and requires batteries. This does provide greater granularity in respect to different pressure settings for different uses and it does work very well. In turn, however, it does mean that you are always conscious about its fragility requiring you to place it down nicely and looking after it much more than you would with a plastic only lance. It is also not a cheap replacement part. Time will tell the lance's robustness and how well it has been implemented. Given it has bluetooth capability, the Karcher product folks have kindly developed an app where you can also control the pressure. Unless I have misunderstood its purpose or have missed an obvious use case, I reckon you can basically ignore this feature. Well of course one reason is that the app requires you to register your details - and there, I suppose, is the business case. In Summary Overall though I really do like the machine. I suspect it will last as long as my 20 year old one but in the same manner as Trigger's brush with many replacement parts. I might though do some research on a replacement hose. There must me an alternative to the one that came with the machine. I'm disappointed with Karcher on this point as I expected them to get this right.

I needed a new pressure washer as my karcher HD expert stopped working. I was bought my HD about five years ago so wasn't that bothered about getting a new machine. This K7 is outstanding. The amount of pressure you get just a setting 2 is crazy, but once you turn it up to setting 3 hard I would say it is more powerful than my old hd expert and that was a £900 machine. I am super impressed. My only gripe is the hose could be a bit longer and it does kink a lot but this is some thing I am going to upgrade. The lance is another thing that I will be changing to a short quick release gun as it does feel a bit big and klunky or as my 7 year old said daddy that looks like the gun the storm trooper used in the new star wars films. Over all very impressed and highly recommended

Used this for a while now, to clean the patio and to wash the car. Does its job as expected. The hose is sturdy which makes it a little hard to roll up, but the way the roll up mechanism is designed avoids the hose from kinking. Wish I could roll up the electric cord inside as well, currently there’s a small net where you can put it in.
