Only used this product once since purchased and seems a pretty good bit of kit. Very powerful, and the need for only one lance with loads of different pressure/spray volume with is available is excellent. The patio/wall, etc washer attachment is very useful. Bought direct from Karcher, slightly more expensive, but comes with an extra year warranty, and the service I received from Karcher when there was a hiccup with the first delivery was brilliant. Being able to wind up the hose directly onto the unit is outstanding for storage.

This is definitely one of the best multi purpose jet washes I’ve ever owned. It is fit for any job around the home & garden. Can even buy accessories to add to the unit - making it more useful for any job. Like car washes and foaming. Decking & floor cleaning. Gutter cleaning. Windows cleaning. You name it. This machine can do it.The only down side is you need a fast enough water supply and a short hose on low pressure supplies… houses with a high pressure won’t find any fault. But that’s okay. If you have a low water pressure supply to your house you can turn down the power to 2-3 bars on the spray gun and it works just fine. Still powerful - tho if I need a high pressure. I just just a hose that is t too long or wrapped on a wheel… so the init can get the supply ... MoreThis is definitely one of the best multi purpose jet washes I’ve ever owned.

So you can do a bigger area without having to move the unit. If you have a small garden you so t need a large hose connected. So you shouldn’t have any issues.For the issues mentioned above. I give 4 out of five stars. But that’s not the machines fault I have a medium pressure supply to my house. But as I said. When needing a long hose you can turn the power down on the unit to meet the water pressure you have & still have a powerful machine.Fantastic machine but ideally need a good water pressure to operate at full power.

My old pressure washer was a tiny Karcher model with not much power at all...now this thing is huge! It's a beast! It is quite heavy, however, it has wheels and a transport handle so easy to move around.It has a 10m hose (which coils around a wheel) attached to the gun which is great for reaching around the car and a lengthy power cable. Its accessory holder at the front is great also. The handle has a small display of which you can adjust the pressure, so great for giving a boost to get off those stubborn stains on the ground!You can also pair to your phone which is a great feature allowing you to adjust pressure also, but it also gives you further guidance on the application you are using the pressure washer on. The patio cleaner, this didn't work for me as I ... MoreMy old pressure washer was a tiny Karcher model with not much power at all...now this thing is huge! It's a beast!

The patio cleaner, this didn't work for me as I believe it was faulty, however, contact with Karcher was seamless and they sent out a replacement within a few days.Overall, this is a great bit of kit, and worked wonders on my driveway! It is compact considering its size as it has storage spaces. I am impressed! So impressed, I have purchased further accessories to compliment it!
A brilliant machine. Made light work of bringing our patio up like new. It’s Indian sandstone, it was absolutely black and it’s come up so much better than we ever thought it would, without any detergent. The T-Racer (patio cleaning attachment) surface cleaner is an amazing tool, you can clean the patio without the dirty water spraying everywhere; up windows/walls/doors etc. Gutters cleaned in minutes. Glad we went for this one as we were looking at the less powerful models but decided to spend the extra. Really glad we did.Just a couple of niggles, there is no mention of removing the grey cap for the detergent bottle, had to Google that (remove it!) and the instructions on the whole could be much more user friendly! Probably one of the worst sets of instructions ... MoreA brilliant machine. Made light work of bringing our patio up like new.

Probably one of the worst sets of instructions I’ve come across!Can’t rate the machine highly enough really, also preferred to buy it direct from Karcher as you get a longer warranty.
Bought to replace my (almost) 20 year old K6.91. Honestly, there’s hardly any performance difference.The Bluetooth connectivity and app are truly pointless! Who wants to use their phone to change the water pressure? Who even carries their phone while jet washing?And why have a gun that needs batteries to power the lcd screen (why have a screen?)?What was wrong with the old ‘twist’ feature to set the pressure?All these ‘improvements’ add nothing to the performance of the machine, and just feel like pointless gimmicks.Karcher, NO, STOP.I doubt all these new electronics will last (certainly not 20 years)I’d take my K6.91 over this over complicated techno marvel any day.
The Smart Control within the lance makes the washer much more practical to use, switching from detergent distributor to high power washing to low power rinsing down very quickly, no issues with connection to base unit.Very stable, very powerful.I have brought a third party 6m lance to clean first floor gutters and facia using an adapter, the Smart Control still works even the the karcher lance is not in use.Ultra foam adapter is a must, makes car cleaning very fast.The t racer patio cleaner is very powerful and has even cleaning for large surfaces, I’ve used it on walls successfully.Detergent dispensing is easy with the smart controls, the modular detergent bottles makes things simple to use.Would definitely recommend
I purchased this just over a month ago and have only used it once to clean Yorkshire stone flags (lots of them).I initially had a problem with the delivery and items within the box, however Karcher sorted that out pretty much immediately.Heres my honest feedback…Pro’sClean large areas quickerIt’s a super powerful machineLots of different options and settingsCon’sThe Bluetooth lance is a real gimmick and keeps disconnected causing the lance not to work.The unit it super heavyNot the cheapest but managed to get it in a deal (£430, after cashback)Overall if you don’t mind spending the money then this is a great machine.
I have spent the last week using the K7 toclean my concrete drive & footpaths indian stone patio and block paved parking area using the rotary head for patio & parking area it did a superb job on both. The concrete needed the wand set on the hard mixed setting at full pressure (180 bar) and it was a doddle. With my previous washers it took hours & hours each day with the power of the K7 it was fast & effortless taking just a couple of hours each day. The pressure setting means a lower pressure to rinse away dirt and debris was much easier too. Did’nt bother bother with the app it works perfectly well without it. Well made quality feel does a superb job I fully recommend it.
Awesome piece of kit transformed my driveway and garden. I didnt realise how muchdirt and grime had built up over the years especially living on a mian road until I used thison my drive. Very easy to put together, it feels well built and sturdy with solid clicking together of parts andpretty easy to de assemble and pack up again. I used the dirt blaster on my large concretedriveway and it pretty much got it a few shades lighter even removing some motor oil stains.My only issue was that the dirt blaster stripped some paint off my stonework bordering my drivewayas it very powerful but that was more down to me not using the correct attatchment and setting, alsois a bit loud got the neighbours attention. Overall a great piece of kit I cant wait to use it ... MoreAwesome piece of kit transformed my driveway and garden.
