For those who need to clean larger surface areas with more power, the Kärcher K4 Premium Eco!logic Home is a truly advanced medium level pressure washer, boasting a hardwearing aluminium pump head. Thanks to an eco rotary switch energy and water is reduced by up to 20% for a true energy efficient model with excellent results.

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.

  • 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.

Q & As

Rated 4.7 out of 5 by 15 reviewers.
Rated 5 out of 5 by Excellent product After a lot of research we chose to buy this product. We have only used it once so far though, to clean the patio, but were very pleaded with the results. It was a lot less messy using the patio cleaner, compared to our last machine which didn't have one. We like the idea of being able to use it by drawing in water from an open reservoir, eg water butt, but haven't done that yet. It would probably be a good idea to review it again after having used it a few times, or indeed after having used all the functions. A three year warranty was also a plus. 14 July 2015
Rated 5 out of 5 by Karcher k4 Eco Logic Premium The Karcher range of pressure washers are well known to me with both extensive use in an industrial and home environment. It's plain to see the quality in the Karcher products and the one I have just purchased, a K4 Eco Logic Premium is no exception. I've used it several times and the results are outstanding. Patio,car,general washing with a first class finish. Also the home delivery service is truly excellent. I was texted by Jimmy the driver twice to keep me informed as to the delivery and spot on it arrived bang on time. A certain other home delivery service would do well to see how things are done properly as Is The case with John Lewis. 04 July 2015
Rated 5 out of 5 by I cleaned up on this purchase The K4 is brilliant so far. Relatively easy to assemble, but two hands, my son, was very useful. Once assembled it is quite heavy and seems very well built. It pack a punch when you pull the trigger so make sure that you are ready for the recoil. I have cleaned my front brick drive, the path down one side to the front entrance and down the other to the rear of the property. The patio cleaner does a good job of bringing up the bricks clean as new and then the blaster wand blows out the weeds. The finish is immaculate. Beware as everything gets sprayed in a mist of dirt blown up by the pressure. Shoe and cloths, cars and walls. A wash down with the pressure adjustable wand afterwards clears up very nicely. It uses far less water then a hose pipe, so I used the hose to wash away the slurry left from the pressure wash of a fairly large area that had not been cleaned in several years. 23 June 2015
Rated 5 out of 5 by Love it! I really love my jet wash. I've only used it on my paving so far, but it did a marvellous job. I wasn't expecting to have to put it together, but actually, it was really easy. And I felt quite proud when I'd done it and got it working. My partner brought me some ear plugs... and I'm really glad he did as I got really carried away and did loads in one go. It's quite noisy. Would highly recommend. And I'm going to lend it to as many people as possible. 12 May 2015
Rated 5 out of 5 by Excellent all round product Having just taken delivery of a new car and wanting to keep it clean without using the dirt / stone laden brushes of my local jetwash, I bit the bullet and bought one of these. Its an excellent product - loose dirt just comes straight off the car with the hose, and then the optional foam gun is excellent for spreading shampoo over the car. Quick rub with a microfibre cloth and then rinse using the K4 and car is all clean and shiny again. Its also brilliant for doing the alloys - just spray on some specfic wheel cleaner, and then after a minute or two all the baked on brake dust comes off with nothing more than a spray from the high pressure lance. The patio cleaner is brilliant too, amazed how dirty my patio actually was! It takes 10 minutes to assemble out of the box, another 10 to read the instructions and then its very simple to use. All the attachments stow away on the cleaner which makes it very easy to wheel around to where you want it. Very happy with it. 15 October 2014
Rated 5 out of 5 by Cleanest car ever Having used Karcher industrial pressure washer in Germany 20 years ago I am surprised how good this one is. It came with a 5 year guarantee. Only fault is length of cable or hose could have been longer to compensate. The patio cleaner is great no splashing friends warned my wife the doors and windows would be splattered but this is when the lance is used. Well pleased I am. 12 July 2014
Rated 4 out of 5 by Surprisingly powerful and fun to use Pricey equipment but should serve us well over the 5-years guarantee period. I had to assemble the wheels, handle bar and winding handle to the yellow colour body with the self-tapping style screws which were supplied. The machine, the hoses, the lance and attachments and the T-Racer patio washer are of robust quality and perform efficiently. The only annoying thing is that a user will have to trail behind him or her the machine, power supply cable, the inlet hose from the tap and the green outlet hose attached to the lance. Avoid water contact to the electric socket connection. This model stows things easily and wheeling around is effortless. Certainly recommend it for larger and frequent jobs. 09 July 2014
Rated 5 out of 5 by Fantastic piece of kit What more can you ask for ? A fantastic pressure washer, lots of accessories and a 5 year guarantee. John Lewis are the best. 08 July 2014
