K4 Premium Full Control Home is rated 4.0 out of 5 by 23.
Rated 4 out of 5 by from Really Pleased With It I bought this Karcher pressure washer to replace an old one (not Karcher) which was a gift many years ago. I found it easy to assemble and use and is much quieter than my old one. I have recently cleaned my patio using the T-Racer and am delighted with the results although I need to master the art of fixing the detergent bottle correctly to the machine to automatically mix the detergent with the water. It cleaned my patio very well and the detergent smelled lovely! I have used the pressure washer on my bicycle with great success so next stop is my car. All in all it is easy to use and I am pleased I bought it.

Rated 5 out of 5 by from Great pressure washer Bought this one a few months ago to replace my ten year old machine. Great product with many new improvements. Especially like the detachable gun and wind up hose. The only criticism is the turn control for the different pressures from mix to medium to full. This could have been mad better if the control unit had some form of click turn so that you knew you were definitely on the next pressure rather than having to wait for the light in the handle to change and confirm the setting. Hope this makes sense. It is so easy to get out, use and then put away much quicker than my old model which took time.

Rated 3 out of 5 by from Disappointed Not as easy to use as my two previous Karcher pressure washers. The product features of this new model are " over hyped " The full control system continually changes its setting number during use ie when stopping and starting a wash using the lance trigger. The lance hose is to short. Its OK for washing a small car but on medium to larger cars you have to keep re-positioning the machine which is a real pain. I wish I had keep my previous model ( a 520M ) which had a 7.5 metre supply hose. Finally its almost impossible to store the power cable in the storage pouch at the rear of the machine .

Rated 4 out of 5 by from 3rd Karcher Washer each one better than the last I purchased this on promotion to replace one that was of bulkier in size. I even sold my old one in minutes of being locally advertised, that is the power of the Karcher brand. I mainly use pressure washers for the families fleet of cars in conjunction with the foam nozzle and for cleaning the deck. This one is a lot more manageable than the last and has much more power. I particularly like the way the hose can be detached so much easier on the new models with a quick release adapter and I have purchased a longer hose attachment. I am not a big fan with the rigidity of the hoses as they tend to coil up and tangle easy but I guess they need to be that way to handle the pressure?

Rated 5 out of 5 by from Wow,wish I'd bought years ago!. I have always,bought cheap pressure washers in the past,thinking they are all the same. How wrong I was. I cannot recommend this product enough. I have a paved area which used to take a good morning to clean with my old pressure washer, I was done and dusted within the hour using the t350 patio cleaner. I have also bought a f10 foam attachment for cleaning my car,it really does a fantastic job, leaves the car with a lovely shine. The foam cleaner has a dial for the amount of foam you use,I have it roughly half full and can get 7 car washes out of one bottle,the bottles of cleaner can be bought online for £5.95. I would definitely recommend this product. 10 out of 10. Keep up the good work karcher.

Rated 5 out of 5 by from Karcher K4 Full Control Premium I purchased the K4 yesterday having read all the reviews online. Having unboxed and assembled I was itching to try it out even though it was a bit late in the day. The results surpassed my wildness expectations for a domestic machine I had previously always loaned a commercial washer from work and the dirt blaster equalled that..Although I had only indented to have a trial run, the machine performed so well, I ended up completing all my driveway and the side path to house in a couple of hours.

Rated 5 out of 5 by from Great all round machine Bought it back in May had a great offer on. First job was cleaning the back patio. Worked wonders. Made it such a easy job. And I used the stone cleaner which left a nice fresh smell. Second job the SUV. I hate cleaning cars but after getting a snow foam attachment. Wow what can I say it was fun. Defo a must. Overall the machine is wonderful. So easy to set up no fiddly bits. Plug and play. Easy to move around with the extending Handel a wheels. This is a a need in any ones life and what can I say it's a katcher. It says it all

Rated 4 out of 5 by from A very good product marred by a annoying feature Really delighted with this it cleans the car really well and my patio...well everyone thought we had a new one laid, however it has one annoying feature and that is the pressure settings. Hard for patios, medium for car and soft for wood. For the life of me it will not go to the car setting it flicks backwards and forwards from hard to soft, although you can visibly see the pressure change. The design is brilliant and ergonomics is well thought out and I would buy it again even with its idiosyncrasies.
