Overall I feel 3/5 is an accurate score to give this item. The pressure washer itself is great and perfect for the jobs I need it for, the other parts of it are inadequate.My bundle arrived with a damaged hose and a damaged T-Racer. Credit where credit's due to Karcher, I reported it and was acknowledged and sent replacements without hassle (thank you).The hose itself is terrible - go and get yourself a flexible version for circa £50.The T-Racer does do a great job but it is so fragile. As previously mentioned mine arrived damaged (the plastic inside holding the brush was snapped) but even following the instructions carefully to not use the T-Racer to brush I managed to damage mine and now the brush bit goes up inside the T-Racer making it useless and at over ...

To be honest I haven't used pressure washers before and have used this just the once. I wondered if the accessories were useful or just took up storage space. I'm so gld I got them the floor washer was great and stopped dirt squirming everywhere and the car washbrush was good too. The machine works a treat.Two complants. The handle was a bit rough and after an hour of work squeezing it with wet hands I did worry I'd get blisters. And the instructions are pants. When you buy the machine, glowing testimony about how it's good for everything. When you check out the cleaning tips they're all very generic and say you should have bought different accesories. I want to know how to use what I've got the best! Sorry that was a rant.But it's still a good machine when I ...

Well I shall start with the negative. The only 2 negatives are the hose pipe connection comes lose and leaks so have to keep lighting it up and once the hose is on the gun I can't get it off as the yellow release button looks like it is nearly broken stuck in after jyst trying to remove it.Positives are for £169. 00 I got such a fantastic deal it has wash and waxed my car. All drive and slabs look brand new. Got the green off my fence took the weeds up no problem too big for this karcher 4. If you are thinking about buying it . Do it my gosh it is so powerful . I own the k2 and wow the k4 is do much more . If you in doubt which one to buy . This does everything so easy to use and comes with 4 bottles of cleaner 2x blue 2x white .

I got the polar shampoo and live in the country side my car still clean 4 weeks later as the wax won't let nothing stick to paint work.. windows are clean 👌. Just go and buy it I can say I wasn't sure but I am so very very happy I did as my drive and back is so clean looks brand new .I am so very very happy clean All round .
Bought this to replace a much older model and I am generally impressed and pleased by all the improvements that have been made. I particularly like the new control handle and pressure indicator. Also the new spinning brush is very useful. I have given a score of excellent for the cleaning performance of the machine but I was not impressed by the shampoo which definitely does not do what it shows on your video. I used it on my car as directed (spray foam all over pre-wetted surfaces and wait a few minutes before rinse off) and was disappointed to find the car almost as dirty as before I started. I am glad that the shampoo was supplied as part of the deal on the machine as I would not have been happy paying for it.Also a bit disappointed that on the day after I ...

No apology was offered for the inconvenience involved in dealing with the your error.
I bought this model because it included the T-5 patio cleaning head for my patio. The first time I tried it the head kept stop/starting so was really unfit for purpose. I contacted karcher about this and it turns out the heads with the green nozzles aren’t compatible to my machine although it all came has one set?I apparently needed grey nozzles so I was told that they would sent me them straight out 3-5 days, 5 days later and still no sign so I contacted them again and it now turns out they are out of stock.So I basically bought this model with this head that won’t even work where I could have saved money and just bought the k-4 machine.I thought after all this hassle I’d be offered some kind of compensation maybe a bottle of cleaner but not a thing. ...

My old Karcher gave up the ghost so time to get a replacement.Went for the K4 this time (had K2 before)The package came with all the accessories for car and patio cleaning and even included 4 bottles of cleaning product, which was very welcome!I love the vario control and the circular attachment for patio cleaning is a must!The car foamer is OK but not great. Overall I’m a happy customer, but Karcher really need to come up but a better quality hose. The hard plastic hose supplied, kinks very easily, making it difficult to manoeuvre. Shame as it lets the product down and you would think that Karcher would address this if they want to maintain their position as a quality supplier. (Others seem to change to a rubber hose, which are available elsewhere and this ...

I bought my power washer as a replacement for my older washer. In reflection, I wish I hadn’t bought it. The one I had was better in many ways, although it was a much cheaper model. The new one , the pressure hose has a mind of its own , you are supposed to thread it through a hole in the body , which is almost impossible. When you have finished, and pull the pressure hose back in, it is so unruly that it kinked twice , so I am expecting it to split in the next couple of uses. I have used it twice now , found it useless unless you have it on the highest pressure setting, so makes a joke of the pressure settings. The accessories that came with it , the car cleaning brush for 1, is useless, the brush part that spins, or supposed to spin , doesn’t have enough pressure ...

I’m seriously considering, going back to my old pressure washer, and try to sell it second hand for £50 and that is overpriced!!!! Sorry Karcher, but the K4 is total rubbish
Ok, so there are cheaper brands out there; friends I know have gone for more affordable options, but I’m super pleased I went for the Karcher. It’s quick to set up, the functions are straight forward and the machine on the whole is easy to use. It’s full of power and makes light work of the patio, drive and car. I typically take the car to the local jet wash (£10-12 each time I might add!) but I struggle to remove the tar and little fly corpses, however the Karcher hand held car wash tool got rid of 95% of it with no absolutely no trouble. I get the feeling that if I do it regularly the results will get better each time. My car is literally gleaming. It can be difficult to angle the car wash tool upwards or low down when it’s on the rod, particularly if you’re ...

It can be difficult to angle the car wash tool upwards or low down when it’s on the rod, particularly if you’re trying to get to somewhere that’s hard to reach, in that respect I wish there was a lightweight versatile hose you could attach it to but I certainly wouldn’t knock off a star for that overall, I can live with it. Back to my original point, friends have been disappointed with their cheap machines complaining how much longer the job takes, by repeatedly going over things to get the same result. I still think I got a bargain with the K4 Home and Car deal but I appreciate it’s a lot of money for some, but I needed something decent due to the workload it would have. My grandpa used to say “buy cheap, buy twice” - hopefully if I look after this it will last. Really happy with the purchase.
While my jet washer was as described and sent and arrived on time. The delivery service was great and could not be faulted and the driver was polite and helpful. Unfortunately the inner packaging had items that were not secure in the box. Unfortunately my new jet washer was scratched and marked leaving it having a "second hand look" right out of the box. Some of the inner connectors had polystyrene pieces stuck in them. My container's of cleaners had damaged tops. When using my jet washer I have found the hose lead to be very difficult to wrap up and store , it is very much like trying to put clothes on a small child that fights you every step of the way.

Just a bit of care and attention to detail when it comes to packing would have enabled me to give this item a fantastic review. But having a "used look" out of the box is not a great start.
