Kärcher K4 Home Pressure Washer

Product information

Please note: This product is not available in our shops for viewing. However, you can still place your order in store. Never direct a pressure washer at yourself or at others.

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

Q & As

Rated 4.7 out of 5 by 24 reviewers.
Rated 5 out of 5 by Great value at John Lewis! Other retailers had offers of 20% or 30% off pressure washers, and I very nearly hit their BUY button. Then I checked John Lewis, and their normal price was another £10 cheaper still. With John Lewis reliability it was an obvious choice. The K4 Karcher pressure washer is a brilliant piece of equipment, they've got everything right. Try not be swayed by cheaper alternative brands, they just don't have the power, resilience and reliability of Karcher. 28 July 2015
Rated 3 out of 5 by Not the quality product it once was This is my second Karcher pressure washer with much less cleaning power than the previous equivalent model. It does a reasonable job but the patio cleaner is particularly ineffective. Very small jets and very little pressure. My previous model was far better. The only superior point about this one is that the motor is much quieter. Don't get too excited about owning a Karcher. There is nothing particularly exceptional about them anymore 15 July 2015
Rated 5 out of 5 by Excellent product Easy to use, light weight makes manoeuvring easy. Electric power extension cable required . Amazing results achieved in next to no time from cleaning patio,drive,conservatory and car. Highly recommend this product. 14 July 2015
Rated 5 out of 5 by Worthy Replacement The Karcher K4 Home pressure washer kit is a good buy if you want a quality product, for occasional use at home, on your car, bikes, patio etc. What is in the box will get you started and there are additional accessories to be had to make washing jobs easier. Earlier this year my old pressure washer finally gave-up the ghost and so I went looking for a replacement. I knew what I wanted: a full-force dirt buster, a variable power attachment and a dedicated patio cleaner to give a better finish than you can get from a standard lance alone. This package has it all and the Karcher is a clear step-up in quality over what I had previously. Recommended. 07 July 2015
Rated 5 out of 5 by Does what it says on the package - very well! We bought this on a Which? recommendation and indeed it has lived up to its billing - it cleaned our never-previously-properly-cleaned terrace extremely well. Points to bear in mind are that it is quite bulky so does need about 1 sq ft to store it on, and that the "patio cleaner" rotary attachment is less effective, though much faster, than the concentrated jet, so you may choose not to buy the "Home" version which involves extra cost for that attachment. We are certainly extremely pleased with our purchase and look forward to trying it out on car cleaning and other tasks. 24 June 2015
Rated 5 out of 5 by Great Pressure Washer The washer was delivered promptly direct from Karcher. Assembly was straight forward, and I had it up and running in no time. The washer works great and now I am looking for more things to clean. 12 June 2015
Rated 5 out of 5 by Excellent product and attachments Bought for my husband. He is thrilled with this product and found easy to assemble. Has used cleaning car and drive with excellent results. 09 June 2015
Rated 5 out of 5 by So robust This machine oozes quality. It fits together like a dream. My patio had been rather neglected but now looks like new with very little effort . The machine is very robust and stands firmly. Would recommend 07 June 2015
