      This jetwash is perfect for general home use. When it arrived I started to worrie as the size of the K3. Small box, Slim, not heavy at all, so I hoped it will be strog enought to clean up my stone patio. What a suprise! The jetwash gives you great power as it says around max 12bar. The 1600w power gives you more than enough to clean objects, wash your car properly, and clean your patio rapidly. Top tip:
      Connect the water hose to main water supply (i did put it to washing machine water supply) to give the machine full water support.
      – Slim and easy to carry
      – Power is enough for general Home use
      – 1L patio cleaner supplied in a box, built in tub for your cleaning material, enough to clean around 20m2
      -Easy to operate and assemble

      – You need to buy water hose and conncetors seperately
      – A little bit noisy, but thats obvious.

      Highly recommended for anyone who wants to clean their garden items, stonework, wooden patio, or a car or actually anything with high pressure.

      The Karcher K3 pressure washer arrived on time. I previously had a Karcher K2 for the past 6 years which was very good. So I decided to go to the next model up which gives more pressure. I have started using the pressure washer and it is excellent and good value.

      Literally no pressure from the washer. Contacted Trafalgar cleaning and was told to call a number. I called the number and they where basically trying to blame my hose that connects to it. I told them my hose is fine and attached a pressure washer recently without a problem. Bad customer service now returning for a full refund! Update having major problems getting a refund the company are giving me the run around please don’t buy from Trafalgar cleaning just Google them lots of people complaining.

      Most jet washes are pretty good at jet washing, but this Karcher gives you a lot of flexibility that most jet washers can’t match. This wash is supplied with a ‘vario lance’ that allows you to turn down the intensity of the blast which allows you do tune it to just the right amount to clean bicycles or your car without worrying that you’re going to take the paint off. Turn it up full blast though and this thing will cheerfully take painted wood back to the bare wood, or clean the gunk off your patio.

      Set up out of the box isn’t as easy at it should be, as the pictograms in the manual are confusing and hard to interpret. You’ll actually do better looking at the picture on the box than reading the manual to work out how to do it. Note you’ll need a philips screwdriver to put it together, but it’s very easy to do once you realise what’s what.

      Everything clips on the main body of the washer when not in use, but the hose tidy and the cable tidy.. aren’t very tidy. They are little more than hooks to drape them over, and it’s a bit of a mess. The gun and attachments on the other hand click decisively into place, and are unlikely to fall off and get lost.

      The kit also comes with a patio cleaner, and while there is nowhere on the unit to store this it’s a great extra to have. You can clean your patio just as well with the ordinary jet if you prefer , but the patio cleaner keeps all the spray-back under control so you don’t end up with an immaculate patio and a mud-spattered house. It’s well worth the extra for this if you’re intending to use this washer for this purpose.

      The washer has a reservoir to store detergent, and is supplied with a bottle of patio cleaner to trial. I can’t say the patio cleaning fluid had any effect at all that I could notice, but the reservoir is very useful if you intend to use this for cleaning your car or other bits and pieces.

      It’s easy to hook up to your hose pipe, and the on-off switch is easy to use and nice and big and ‘clicky’ with a positive action. The gun itself has a safety catch with a stiff you can leave it unattended without worrying about small children having a go when you’re back is turned. It’s quite noisy in use, but not excessively and about what you would expect for a jet wash. The pump only runs when the trigger is pulled, so that’s the only time it’s noisy.

      You will need a hosepipe to connect this washer up, (obviously) but you’ll also need a standard hozelok style quick connect coupler to connect it to the washer. There are no fitments supplied to attach this to a kitchen tap, so you if you intend to use this way you’ll need to have a way to connect your hose up. You can’t use this washer out of the box with a water butt, but I understand Karcher do an attachment that will allow to use it this way.

      It’s a great bit of kit, and has lots of flexibilty so you can use it numerous ways. You’ll get a lot more use out of this washer than most ‘one-trick pony’ jet washes. Recommended.

      The media could not be loaded.

       The assembly instructions aren’t the best but you can get there if you concentrate. I also had a look on youtube but they tended to be Americans with slightly different models. Anyway once I got set up it was a great little machine and I didnt want to stop. I’ve attached some before and after pictures. My patio was like brand new. I am really impressed as it’s quite compact but the power is excellent.

      Not sure if this is the one from Karcher itself which is perfect or the one from Trafalgar, which arrived broken and I still have not had my money back in over 4 weeks now. The Karcher website is excellent and £60 cheaper than Trafalger cleaning who are crap

      Great product and very easy to use. I have used cheaper pressure washers that were a bit of a let down and broke down. Glad i paid the money for a far superior product. Delivery service was great too as it arrived 4 days early.

      Excellent product as you can see from the pictures that have taken the front and back of the house was completely black and green from rainfall assembly is quick and fast push in and turn recommended for cleaning tiles cleaning car and all round outdoor general cleaning I would recommend purchasing to snap ons for the hose 1 and 1 for k4 as seen in picture provided you will definitely need them would have loved to seen the price drop down by £15 to £20 to maybe get a 5-star on that but other than that thumbs up. My word is true and accurate I hope this helps people make their minds up.
