This K7 is powerful but effortlessly useful. I was able to wash 10 years of dirt and grime from my patio in no time at all. The easy to use controls give you the ability to tame the power for all jobs. Brilliant buy it! My K7 version didn’t come with the Bluetooth app, but I don’t think you need it as my phone won’t be anywhere near me when using my K7.

Saved a bit in a flash sale! This is a very powerful washer with modern high tech controls. Clears muck off of slabs with ease, great for the car, garden furniture etc. Will strip loose paint (so be careful). Hose storage is very good and while cable storage not perfect it works well. Whole thing is easy to manoeuvre and the long hose gives a lot of freedom when working. The very simple detergent dispenser works well and bottles can be refilled if you want to. This is quite a heavy piece of kit but the large wheels and retractable handle make it easy to move around. I have owned quite a few Kärcher tools in my time and have found them to be well made and reliable.

Make sure your water supply tap has sufficient flow rate. It needs an input flow rate of at least 12 l/min. My outside tap can only do around 4 or 5 l/min, so I ended up having to run it from my kitchen tap inside. This is not clearly advertised anywhere besides the specifications table in the printed/pdf manual.

Previously had a cheaper one from Aldi which I thought did a good job but was load run running and died this Summer. I was dubious about spending a lot on a named brand like Karcher but took the plunge and it has been a revelation. The output is huge and a massive time saver added with the adjustable pressure means no longer tearing into surfaces unintentially. The soap dispenser and generally ergonomics are great and much more user friendly. Should never of doubted myself and took the plunge years ago.

Good buy, used lots of times would highly recommend

Used for a couple of hours. Pressure lance works well with more control of both pressure and detergent delivery than my previous pressure washer. The Patio Cleaner worked well until it picked up an 8mm stone from between the slabs I was cleaning - I'd brushed the surface before starting. By the time I stopped the cleaner four pieces of plastic had been broken off the inside of the shroud. These were some of the "struts" whic help support the brush which keeps spray inside the shroud. Hopefully glue will fix them back in place. My error as I should have ensured no stones were loose where I was using it - There is a warning in the manual about brushing before use.

Wow Amazon another excellent fast delivery virtually next day, what a machine, super powerful, I know I’m a landscape gardener who use jet washing all the time, all I can say is it’s more powerful than the karcher HD 6/13 professional at £780 that I normally use on the farm. This machine has 2.9 kw that’s a lot when it comes to force. I would recommend this. Even got a free robot floor cleaner and solution. Super happy about this for my job. First initial use blew me away with the power wasn’t expecting that. Did a full drive 30m2 in 1 hour it just plough through it. Need it for the van too so I bought a foam gun

Purchased this to replace a k2 as the attachment got dropped & wasn't working & I couldn't find the patio head cleaner so decided to get the latest model, really pleased I did as this jet wash is simply awesome. on full power I accidentally caught my varnished steps, there's no varnish on the step anymore. A years dirt came off the decking in seconds and on full power started shaving the wood from the decking board so dropped it a power level to ensure that stopped. It has a really strong, powerful & large water dispersion on the hard setting, soft setting to clean the gutters & glass, the plastic shed was de-allgied in minutes on full power. I love this product and it is up there with my iPad Pro as the best purchases I've ever made it's that good & I genuinely like using this product that it makes me want o go out & clean something.
