Phenomenal jet washer
I had previously used a £10 jet wash from Argos which would rapidly overheat and cut out every 30 seconds or so.Having purchased and used my Karcher WD-5 vacuum extensively, I know this brand is set out to create durable and effective products. As such I did a bit of research online about the various pressure washers to get a feel for what I needed, with the K7 coming out on top.I wanted to get a machine that was powerful enough to clean my patio, but also have the ability to wash my car. The digital lance provides some excellent features, allowing you to choose the right setting for the job. You can also adjust the strength of the blast, including a boost mode which puts out an incredible force for a non-professional unit.The ball bearing rotating mode is crazy good. I had a lot of moss and lichen on my patio, but this mode just made it look like nothing. What normally would have been a job involving some harsh chemicals and tonnes of wire brush scrubbing has gone - all replaced by a powerful pressure washer that makes easy work of it all.I’ve also bought attachments for my lance to allow me to snow foam my car, making trips to the car wash a thing of the past. Using the K7 brings a bit of joy back to some of these typically mundane jobs, mainly because it’s so powerful and feels like something only a pro would use,It’s on the expensive size, as well as weighs a lot, but that is offset by its performance. The pressure is immense, the hose is a decent length and has a retractable wheel to store it nicely, it can also be wheeled around easily using the built in handle and wheels, much like a suitcase.The only minor thing to note is there is little splash resistance. Given the power and modes on the lancs, it’s inevitable that you will wear some of the water that you are spraying. You can get extensions for cleaning patios which contain the spray, but they cost more and I don’t think they would be as effective as the ball bearing mode anyway.

Excellent machine.
Bought this machine to replace a previous Kärcher that had been damaged due to frost. This machine is excellent. Very sturdy and powerful cleaning ability. I’ve used it to clean my block paving driveway and it was a treat. I use it to clean my car with an additional snow foam bottle and it’s great. Various bottles of shampoo, stone cleaner etc are available and fit very easily into the bottle holder on the machine and work really well with good quality foam. Assembly is simple and the power cord and jet hose all store neatly on the machine.I did my research before buying as cheaper options are available but this machine is quality and for me is good value for money. I recommend.

K7 What a beast of a pressure washer
Arrived from Amazon the day after ordering, you cannot fail to be impressed with Amazon delivery (and returns if you need to use it)Setup took around 15 minutes, they have simplified the app set-up which went smoothly (once I had turned on Bluetooth on my phone) you can then control the different functions of the K7 nozzle power.The new hose system on this model is a breeze to use no more getting tangled up and having to keep spinning the lance around to untangle. If you are cleaning slabs hold on tight the top most powerful setting nearly takes off its that powerful, it moves old grime and green mildew like nothing i have used before, its also very quite compared to my old K4. I have cleaned the cars, patio's, walls, guttering, the bins, even cleaned out the water butt.I can recommend the Karcher cleaning fluids that push into the top of the machine, a little expensive initially but you can re-use the empty bottle, I purchased a Karcher 5lt bottle from Amazon and topped up my empty 1lt bottle .I have even volunteered to power wash for my neighbours in return for tea/coffee and cake.Go get one I cannot recommend highly enough.

Expensive. Imperfect. Lots of power!
Assembly instructions are reasonably clear and easy to follow (except for the accessory net at the rear).The washer is rather heavy so the telescopic handle comes in handy (the handle does feel very cheap though) as you'll be dragging it around a lot.I was hoping for something with enough pressure to clean my oily driveway and moss-covered garden walls, and the k7 did not disappoint!An industrial washer will probably do the job faster but the k7 is more than enough for all grime and dirt. Only the baked-in engine oil spots remained.DO NOT use the patio cleaning lance on anything covered with paint (especially a car). It'll strip any paint which isn't 100%.You'll need to buy a hose to go from your tap to the machine as there isn't one included. A regular non-kink hose from a superstore is ample.The hose from machine to lance takes a lot of flak online and they're correct... It is quite rigid and it takes a bit of fiddling to straighten before each use.The trigger on the lance is fine if you're just rincing your car, but if you're doing a whole driveway your fingers will get a little fatigued towards the end.I've tried washing the car with just water to see if the pressure alone will clean it - It doesn't.I still fill a bucket with hot soapy water to get it properly cleaned.If I used it every day I would consider swapping the machine-lance hose, and possibly buying a stubby gun, but for once per week I think I'll leave it as-is.I read online that I'm supposed to run water through the system (by hooking up the hose and pressing trigger) before switching on the power. Apparently this prolongs the life of the motor. I'm not sure if this is true but it only takes 10secs to do so it's not a hassle.That's it really. It's a cracking bit of kit. It's heavy. Some bits feel a bit cheap. Accessories are available. It's got more than enough pressure for home use.

Great pressure washer
This pressure washer is brilliant. Had black and green mould on my patio and we bought this and it did the job perfectly. Im absolutely delighted. Well worth the money. Definitely quieter than they used to be. Highly recommend.
