    I love Karcher power washers and i have been using my large one for years, however i have found my existing one a bit over the top for the smaller jobs and this – i think – is where this K4 compact washer comes in.

    When the washer arrived it was very well packaged and has the usual high quality graphics on the box from Karcher.

    The unit is really straight forward to put together with no real technical expertise required. Once i connected it together i found that my hose connected simply too and for the first time use i wanted to wash my car so i used the soap dispenser tube that i pulled out and put in a warm soapy bucket with detergent, which then flowed into the stream of water during use and cleaned my car with soapy water. To stop the soap i simply took the tube out of the bucket and normal water washed off the soap.

    One of the things that i first thought about on reviewing this unit is just how light it is compared to other units and i think this will appeal to people who cannot use heavier washers. One of the other things i like is how the cable stores away. My existing large model is more awkward (it’s an old one) so the way you wrap this up is really handy plus because of it’s size it just stores away easily.
    Now i wouldn’t say to use this on really large, heavy jobs – you obviously need a larger unit for that, however for cleaning paths and washing cars etc i thing this is great.

    As you can see from the pictures that the hose inlet and high pressure outlet are in a completely different place as the sales picture show you are not able to use it lying flat it has to be upright. Also the high pressure hose connection does not look very robust ! Only time will tell. It works well just the layout for the the hoses is totally different as car be seen in the pictures I’ve taken and added.

    Karcher washers all seem to have a small failing for me, the telescopic handle goes back into itself if pushing is needed instead of pulling. They will not lock in the extended position and it inevitably catches me out.
    This NEW K4, has a single, central support for the handle which does lock open, YEY ! See my photo’s note the neat storage solution for the tools. The photo on the illustration is an older model.
    The washer itself is the sort of quality expected from Karcher, its compact size makes for easy manoeuvrability and the tool carrier keeps them clean and tidy. Enough power (its MPa is 1.2) 1.8 kW motor for cleaning car or machines, soft and hard settings are available on the lance, or just the jet on the other lance. There is also a tube to suck up and combine the various additives available for different jobs. It is also good for patio cleaning though the bigger machines are better for the larger jobs, but Karcher make those too, right up to the marvellous K7.
    Register your purchase for free product repair during the warranty period of two years, so hang on to a receipt, you will need it if you make a claim.
    I think Karcher is probably the best available pressure washer, with a huge choice of models and accessories, so I can’t help myself – it’s got to have five stars.

    Great little pressure washer, very easy to put together, just make sure you push the hose into the handle well, i love the compact size when storing, all the tools have a place onboard when not in use inc the hose meaning it stores away nice and tidy, the only thing missing was somewhere for the power cord but i just wrapped it round the handle, problem solved. It did a great job easily on my patio flags that had gone green over winter. It is easy to move about on the wheels and the handle goes to 2 different heights, if lifting to carry it is really lightweight, a fantastic pressure washer for many jobs round the home and garden eg outside windows, garden flags, car

    For those limited on storage space compact pressure washers are a good option. I found assembly a little less tricky on this than the full size K4 but that could be down to now being familiar with the diagram and notation.
    Understandably the K4 compact comes with less than the K4 home just with a vario-lance and dirt blaster lance but you can add more accessories which the Karcher app which will tell you your set up for cleaning and also offer suggestions of the ideal clean which will helpfully add things to you basket to purchase from Karcher. Because this is the compact version it doesn’t suffer from the little niggles of the bigger K4 because it doesn’t have the hole for the hose to coil round the back or the space to store the electrical cord which keeps this model much simpler. I can’t say I noticed any difference in cleaning ability so really this comes down to how much you want to pay and how much space you have to store the washer.

    The description is wrong for this version of the K4 but this didnt bother me after extensive Googling. This is the same high end Karcher K4 but this is a compact UM version.

    My dislike is the water connector from machine to hose has water escaping, any help would be great because of the price i paid.
