K4 Full Control is rated 4.3 out of 5 by 48.
Rated 4 out of 5 by from K4 home Bought the K4 to replace my faithful old Karcher, It lasted 14 years and done everything I needed it to do. So far the K4 has performed well and is more powerful than my old one and I now have more control with the variable Lance. The fact that you can now use the detergent in the bottle in the machine is great, keeps everything together and tidy. The high pressure hose is 4 meters long which is ideal for going round a medium sized car. The machine itself is very easy to use although it's quite heavy, The only negative thing I will say is that it uses a lot of detergent to wash a car ? I used a full litre to wash my car first time I used it.

Rated 1 out of 5 by from dissapointed I have used the K4 3 times on the patio path at side of the house and the slabs on the front of the house I came to use it today on the car to remove the mud from Leeds festival and had now full power at all. this is the third Karcher I have had in the last two and a half years they don't seem to be made as good as the old ones, My 15 year old one which was very heavy never let me down once till it finally gave up the ghost and no parts where available for it so I purchased a K2 lasted 2 years and 2 months the next K2 lasted 3months so I took it back and got the K4 now that has only lasted 2 months,!!

Rated 5 out of 5 by from nice machine i bought this 3 days ago, everything was easy to set up. the plug n clean system is briliant, i bought brushes for my cars and parkinglot everything is now clean with a great result. i used my old machine 10-15 times a year and im shure i will use this machine more be course its easy to use and gives a good result..... one thing to improve is that the plug n clean system should be able to use with the car brush otherwise i say anything that is not perfect for this price.

Rated 5 out of 5 by from Much improved features I bought this Karcher K4 to replace my old one, the features have been updated to improve the machine, as the handle now locks in, much easier to move around and the hose attachment on the side is is much better to access, also the storage area has improved, things stay in place when moving the machine. I bought this last April, the first one had a faulty screw for the transit handle so it was collected on 21 Apr 16 and the replacement arrived the next day. Excellent service. The electronic display for the various settings on the lance is helpful as I have arthritis in my hands and it was not always easy to tell if I had turned to the correct setting.

Rated 4 out of 5 by from A clean house ready for painting I wanted to paint the old white painted render finish on my house, but it had a large amount of verdigris build up in patches. Having tried with a bucket, stiff brush and chemical cleaner I gave up and went to B&Q to buy a K4 pressure washer! Luckily I had all the necessary hose fittings and once assembled got to work. It made short work of the green buildup and in an afternoon the house was as clean as it has ever been. I had to be careful of the jet wash if it was too close to the wall for fear of blasting off the render but all was well. I wish that I had had a jet lance for the high bits as working up a ladder was not really to be recommended but I was in too much of a hurry to start painting...

Rated 4 out of 5 by from K4 I bought this machine 6 months ago to clean my van. The vario lance is excellent for adjusting the power of the water. There is a design problem with the washer. The power lead and hose's fit into the bottom of the machine so when you try to move it about you run them over and get tangled up. Would have been better if they fitted into the top of the machine to keep them away from the wheels. I can't comment on the full control accessories because even though in my deal I was supposed to receive £100 worth of accessories they have still not been delivered to me.

Rated 5 out of 5 by from replacement I purchased this washer as a replacement to my K411 which packed up after 22 years. In that time all I replaced was the on/off button, so I wanted a equivalent model and I chose this one as I already had a T racer and did not want another one. It has a water cooled motor which the other one didn't also the motor only works when the trigger is applied instead of turning it off and then turning back on after you have moved the washer to a new place. Lastly it has a "plug in" detergent system whereas the old one was a suction hose and the washer is on wheels!

Rated 5 out of 5 by from Does exactley what it should I use a commercial Karcher washer at work so I know the name and quality well, wanted something for home use for the cars, paths etc Good size and weight, plenty of pressure for those tasks and easy to use Unfortunately the add in products use up very quickly, ie the car wash foam etc That is my only gripe
