Great washer but needs a soap bottle
I bought this k4 jet washer after reading the reviews. I'm a no nonsense type of guy and if it don't work it goes and I'd speak my mind. First off it feels great, sturdy and feels like it would hold up to any job. I've tried it and again it inspires confidence in what you are using. It quieter than my not so old Nilfisk jet washer (never again will I buy a Nilfisk jet washer) I pleasantly surprised with my purchase. Sadly theres no soap bottle with it which I'm surprised as most seam to come with even a basic bottle to use. I've no down side to review other than no bottle.
Good machine with minor design issues.
The power is good...great for washing the car and I used a snow lance with it which worked well. Two things that could be improved. The hose has a memory which is uncontrollable...I wrestled with mine for 20 minutes and I still cant get the twists out of it . Surely there is a better solution. I also made the mistake of leaning on the handle which collapsed down nearly causing me to fall. ...it should lock up. lastly its useless to have to use an app to show you how to build it ...total madness. What happened to instruction manuals ? A lazy solution. Doesnt come with a washer bottle for shampoo etc.........even an empty bottle would be ok. Those are the downsides ...apart from that it s good machine and works well. However if you really want a clean patio.with no black spot or algae.........the best thing to do is not to pressure wash it ...........especially if it is stone . Use Sodium Hypochlorite spay it on with a pump sprayer diluted ( see you tube) the remove it gently with your power washer not on full blast.
Hard to beat Kärcher
I received this item as part of the Amazon Vine programme when it was priced at £200.00 with no delivery charge to Amazon Prime customers (11th February2021). Assembly ======== The pressure washer came securely packed and required a degree of assembly to connect the hose, attach the wheels and to assemble the handle. You will require a Philips/cross head screwdriver for the handle only. Assembly takes 5 minutes. Once assembled you are presented with the Karcher pressure washer as illustrated. Setting up for use requires you to connect a water and power supply. Operation ======== There are two separate controls, both of which are simple to operate. An rotary on/off switch on the main body of the washer and a separate 4 option control on the spray wand; this allows for variable spray pressure for hard substances such as paving through to soft timber, such as garden furniture (easy to operate rotary controller with a graphic display). Additionally there is a separate high pressure lance which directs a more concentrated and powerful jet for hard or stubborn stains. Personally I found that the variable lance offers sufficient force to tackle the majority of jobs, including removing heavy deposits off car alloy wheels. Both lances are easy to remove and secure. The Kärcher K4 comes with the added Plug and Clean system whereby you can attach a bottle of concentrated detergent or similar which will be mixed in the machine and delivered under pressure. It is a significant advance on previous models where there was an option to insert a pipe to draw the concentrate into the washer. I have used the car cleaner and found that it used the concentrate far quicker than I felt was necessary and therefore I would suggest that you experiment with concentration and do not attach a full bottle the first time you use it. I found that diluting the concentrate at a rate of 5:1 was more than sufficient to coat my car in foam: you just need to decant the remaining 80% into a separate container for future use. I would also recommend that you purchase at least one of these bottles of detergent should you wish to use your own detergent in the future. as you will need a dedicated bottle Functionality ========== The washer supplied to me was not the upgraded model as advertised and did not have the retractable hose . In all other respects though pressure output is the same and the model is fully functional. It works really well, the 8 metre hose and 5 metre power cable permits me to access all sides of two family saloons parked parallel on my drive. The unit is not exceptionally heavy, in fact the weight is quite reassuring. My wife commented that it was quite heavy, but not excessively and her only reservation would be lifting it any height (11.5kg) Storage is relatively simple. The hose and power cable pack neatly to the rear and the wands are held securely at the front of the main unit. The Kärcher App ============= The Kärcher app is only used on this model to register purchase and to provide guides and tips, although higher spec models allow the app to control certain settings. A useful product guide which saves having to search for the manual if you wish to confirm any element of operation. Overall ===== A powerful mid range power washer which is ideal for the average home. There are more powerful models and those which are less powerful and smaller. For our home, this item is more than adequate for cleaning cars, which I suspect will be used for regularly, combined with annual cleaning of our patios and garden furniture. It has the added bonus of possessing two wands, a very high pressure washer and the much more convenient variable wand with four easy to control settings.

So far... so good
Used to blast off several years of accumulated grime from our decking without any issues. I've borrowed other peoples pressure washers before and always found them to be very temperamental, especially if using quite a long water hose. Maybe only because its new, but no such problems with this model. The hose storage options arent great if Im honest, but I can live it as this will only get occasional use in the garden. I'm hoping the water cooled motor will prolong its lifespan. Buying on "Prime Day" I got this for a great price, so happy days.
Finally found a pressure washer that works
Having tried a colleagues pressure washer and purchased a cheap (around £100) unit in the past and been disappointed, I was sceptical as to whether this unit would be any good. Glad I purchased as the results are fantastic. Cancelled bin cleaning company as it’s a simple job to clean and over the three years covered by the warranty it will pay for itself just cleaning the bin.
Good power. Not, sadly, compatible connection fittings with earlier models. Absolutely magnificent hard surface nozzle and a wonderful price from Amazon - £50 cheaper than elsewhere (What chance for the high street?) Slightly disappointed that the carrying handle is set so low - the previous model could be wheeled without bending.

K4 Full Control Pressure Washer
At first I was reluctant to buy a KARCHER pressure washer, having had a STIHL for twenty odd years. Sadly the STIHL went to pressure washer heaven. Having read the reviews and customer Q&As, I decided on the K4 Full Control (Amazon Choice). Arrived as advised and included an outer packing box. All good. Okay, points to note; It is important to completely unwind and disentangle the high pressure hose, before putting through the hose guide from the back of the machine. Be careful of the transport handle, it is tempting to rest on it, and is quite easy to trap fingers when pushing down to close. I found wrapping the high pressure hose around the machine (saves time, and less likely to split), put the electric cable in the accessory compartment. When using the the T350 Surface Cleaner, use forward and back strokes, rather than moving side to side. This will prevent strain on the connecting joint (common sense, but too late if it snaps). Compared to my previous pressure washer (STIHL); not a lot of difference in the finish job, but a fraction of the cost. Good job and recommended. Lets hope it last as long?
Just buy it, this pressure washer is the dog's jewels!
OMG, this pressure washer is the dog's jewels. It is a solid build and heavy, so the wheels and handle are essential and make it easy to move around. Used the patio cleaner attachment and what an amazing difference to the last time I cleaned it with just a lance. It is so much faster and so much less mess than just a lance. No need to go back round cleaning the walls and windows after all the spray. It gives very consistent results to. I was so impressed I could not stop cleaning, I must have cleaned over 100 square meters of patio in about 3 hours! The auto feed cleaner fluid system is brilliant. Just take the top off and insert the bottle upside down. No mixing or tubes and it goes with the main unit all the time. You can reuse the bottle too so I bought 5L and you can refill it 5 times for the price of 2 smaller ones. I also washed my car with this pressure washer as I was having so much fun. Did a great job with a shampoo bottle, just swapped them over, no spills either. The gun and hose are a good length, though the power cable could do with being longer, but I just used an extension lead. All the cables wind up neatly and the lance and handle store on the unit too. All in one wheeled in and out of my shed! Best buy for years! Just buy this, you will not be disappointed!
Awesome, but BEWARE 2p missing CLIP can cause pressure problems!
Got a great deal on Amazon Prime day, so after delivery and unboxing then setting up was really looking forward to ripping through the Drive / Patio. However as soon as I switched it on I got a fountain at the back of the unit (and no pressure). Could not believe I got a faulty unit!! Did a bit of research on YouTube and Amazon and found a few similar failures, but no one seemed to know why. Anyway after working out how to remove the rear outlet "foot", I realised there was something missing, initially it seemed like an o-ring but then I realised it was a clip to hold the outlet pipe into the right angle elbow that goes to the flexible pipe. As a temporary fix I used 2 BBQ skewers that dropped straight through the 2 holes and held the outlet pipes together. PERFECT ALL WORKING! Phoned up Karcher next day and they wanted me to send the unit back to Amazon for the sake of a 2p clip!!!??!?!? After a little argument managed to get a parts list from them and identified the missing clip. To Karchers credit they got the clip sent from Germany in 2 days .. and ALL IS GOOD!! No need to waste Amazon or Karchers money in warranty returns. This may solve many others issues too. So check if you have this clip before returning.
