For those who need to clean larger surface areas with more power, the Kärcher K4 Home is a truly advanced medium level pressure washer, boasting a hardwearing aluminium pump head.

The hardworking 1800W motor is looked after by water-cooling, so you can enjoy enhanced performance and a longer life. This machine also has a water inlet filter to prevent dirt particles from damaging the pump.

With a liberal 420 litres per hour flow rate and powerful 130 bar pressure, the K4 Home is ideal for cleaning:

  • Barbecues
  • Garden patios and decking
  • Stone walls
  • Motorbikes
  • Larger vehicles

It hosts a Plug & Clean detergent system, which makes for quick and convenient changeover between detergents and offers a seamless cleaning experience. The quick connect release on both ends of the hose reduces set up times even further.

For a completely responsive user experience, the motor stops automatically when the trigger is released. Upright construction, smooth wheels and a higher handle offer excellent mobility when transporting this pressure washer. Meanwhile the lance and trigger storage facility and large cable hook ensures compact storage.

Accessories:

  • Dirt Blaster lance provides increased power, performance and area coverage
  • T250 patio cleaner attachment ideal for flat surfaces such as patios, decking, walls and fences
  • Vario-power spray lance with easily adjustable pressure, perfect for cleaning smaller areas
  • Detergent pack

Kärcher K4 Home Pressure Washer 4.6 5 10 10
Excellent Does what it says it should and a great price from John Lewis, as always! Now have been buying all the additional accessories you can get for these, brush, broom, extension hose, plug in detergents....... the list is endless! 23 July 2014
great buy great buy, have other karcher products and this one is just as effective, makes cleaning the garden so much easier 16 July 2014
Pleased with results This arrived within a couple of days of ordering. There was a very small piece of plastic which had broken off in the box. I worked out where it came from and it seemed to serve no useful purpose so I decided to ignore it. It took a while to put together and I had a bit of help from my son. He was useful when it came to exerting enough force to push some of the bits into place. The washer is easy to use though I found it tiring. I ended up doing my large and very dirty patio in 3 goes as the vibration from the handle made my hand and arm go a bit numb. I haven't used the proper patio attachment yet as my patio needed a strong blast to shift the dirt. The washer is easy enough to move around but I was glad of the wheels. None of the neighbours commented on the noise. Pleased with the price I paid. 09 July 2014
Very efficient and effective pressure washer Recently purchased, it is very efficient on water usage, quieter than earlier models and is great at getting rid of years of accumulated dirt. I used it mainly on patio's and brickwork and it was excellent. 08 July 2014
Very good washer. I bought this Karcher washer to replace an ageing broken down 5 year old Karcher. I started using the K4 on my block paved driveway using the T-250 patio cleaner attachment. After a short while I changed to using the dirt blaster attachment and found it cleaned better and quicker. The reason being at regular intervals you have to swill the dirt/dirty water away during the cleaning process. With the T-250 attachment on you have to disconnect it and then put the other attachment on to swill the dirty water away. With the dirt blaster you can clean and swill with the same attachment. This of course was just my personal preference. As for the T- 250 attachment although it did a good job but it didn't clean as well as the dirt blaster attachment.(hence I've only given the washer 4 stars) Haven't tried it on washing the car yet. Overall I was impressed with the Karcher K4. Very powerful compared to the old Karcher's. I cleaned my drive in a quarter the time compared to my old one. Would recommend. 23 May 2014
Karcher Pressure Washer. This is just great. Should have got one years ago, This comes with a great set of accessories, however we did buy the car wash brush as an extra. Our patio was quite badly stained so found the patio cleaning head not quite powerful enough so we just used the spray on it's own. My husband is out cleaning his van regularly with it. Delighted and highly recommend. Great price and we used some of our vouchers so this made the price even better. 06 May 2014
Happy with purchase Powerful enough for washing patio with a Lot of moss! Easy to use. Useful helpline. Negative it wasn't working when it arrived and so had to ring helpline next dat, which was annoying. They sent email of process to try and remove what they thought was an air block. Yes it worked and no problems since. Better if the factory had tested this first. 06 May 2014
Good product Jet wand works very well, but I have not mastered using the brush efficiently yet. 30 April 2014
