The new K4 Full Control Home power washer from Kärcher is the perfect solution for your patio or decking. The additional home kit makes tackling your outdoor spaces that much easier. The T350 patio cleaner can help you clean up to five times faster than using a standard spray lance. While the handy pressure dial helps to achieve the perfect clean on both soft wooden decking and hard stone surfaces. The handles on the T350 also enable you to clean vertical surfaces easily. The stone detergent helps to clean your patio more effectively, help prevent dirt from returning, protect and care for the surface. Kärcher have developed a new system to help guide you to the correct pressure setting for your cleaning task. Simply choose the correct spray lance based on the surface you want to clean and the symbol guides on the lances. If using the vario power spray lance, you need to select the right pressure setting for your surface, using the LED display on your trigger to guide you. This new system helps you achieve the best possible clean for your home. The long-life water-cooled motor gives you a 3 year warranty. The perfect machine for cleaning medium sized patios, decking and cars.

Rated 5 out of 5 by from Great machine I've not long had my new karcher k4 but I can definately say without a doubt it's my favourite so far .I have always used karcher but always bought the basic cheapest one which I had no complaints with as it did the task however I thought I would upgrade to a newer model the k4 complete and it's great much more powerful and my driveway now looks new condition which is amazing as there's a lot of cars on it daily with 3 sons who drive and myself I've had oil dirt radiator leaks everything spilt on my driveway I thought would never get it removed but now you wouldn't know what had been on it as it's looking great best purchase I've made in a long time .

Rated 1 out of 5 by from Kept losing Pressure! So disappointed I've been a loyal customer of Karcher for yrs. wanted to update my old pressure washer. I phoned to find out midelni should get is K4 Full Control Home. After easy setup I started using it in my patio. However with 5 mins the presssure just kept fluctuation from mix etc it was so frustrating. I read the troubling shouting section did the fixes still no use. Gave it back at Homebase where I bumped into another customer returning for same reason. Why have you made a perfectly good product worse by installing this full control function? It's just unable to self adjust pressure according to surface type. Do not buy u tip they have resolved this issue!

Rated 5 out of 5 by from One of the best products I have ever bought! I was blown away by the results of the K4 Full Control Home. It had all the features I needed. There are a few pieces to put together but that only took a matter of minutes. The quality of the machine was obvious from the start, strongly built for hopefully many years of use ahead of it. I've never owned a pressure washer before & was a bit doubtful before I started if I should have gone for a higher spec Karcher ( I need not have feared). I used the stone detergent in my K4 as my patio that had never been cleaned for 16 years since the house was new. It lifted the dirt off very quickly & I couldn't believe the results. I was so pleased that I have since bought the soft car brush & the FJ10c Foam Jet Connect 'n' Clean & Ultra Foam Cleaner. I haven't used it yet but I will ! I would highly recommend this model

Rated 5 out of 5 by from Quality kit Just finished cleaning patio and path,WOW!!!.My K4 just breezed through the patio,took about 20 minutes with the T4 racer, compared to a couple of hours with my old B&Q pressure washer. Don't waste time with a cheaper washer,this machine is fantastic, only regret is I didn't get one sooner!!!!

Rated 4 out of 5 by from Watch the beast Had it just a week. The performance is brilliant on brick/paving and even removed flaky paint from old metal ttable and chairs I want to repaint. The tool storage could be bigger and it would help is the power cable had a suitable storage position. Cannot understand the function of the displays on the handle as the seem to be for decoration only. Going to have to wait 30 days for delivery of the £100 'free' kit. Seems Karcher hadn't anticipated the popularity of this 'winner'.

Rated 4 out of 5 by from Does what it says on the tin I bought a K4 ecologic 12 months ago. I am pleased with it and it is easy to use, set up and store. The only drawback is the recommendation that it is stored in a frost free area. This is necessary because when you finish using it some water remains in the machine. So - not so good to store in a garden shed or garage which is where you probably do want to store it

Rated 5 out of 5 by from Updated Home Version This is my second Karcher Pressure Washer which served me for a number of years without any trouble. This new one is more compact easier to handle. I am a little perplexed as to where the lances are best stowed, as the previous one had a more obvious position for them. That said, the modifications embodied within the new one are all welcome additions.

Rated 5 out of 5 by from K4 Full Control Home-Brilliant Bought this about month ago,as we borrowed the neighbours pressure washer to clean the decking.It did a reasonable job but not as good as the K4. My missus loves it and class it as her New toy. The only time I touched the K4 was to put it together and to check that everything was working ok. No problem at all, easy to set up with the quick push/twist connect. It's that easy my missus can do it, leaving me to do what I would like to do.
