Kärcher K4 Full Control Pressure Washer

Having previously used a Karcher K2 I decided to purchase the K4 because of the very good price here. I am from Ireland and same machine costs €294.99 at Argos. I was expecting good performance from a brand like Karcher and it did not fail to deliver solid performance. It arrives nicely packaged and can be put together in minutes. I use the K4 to wash my car, patio, walls, driveway, windows, bins, bicycle etc. It has plenty of power and lifts dirt effortlessly. The vario spray lance is brilliant for most tasks but for really stubborn dirt, I would recommend using the dirt blaster spray lance. There is a pressure indicator on the trigger gun but I think this is a bit of a waste of time as it is easy to regulate and judge the pressure. A bottle of detergent can be inserted into the machine but I have not used that feature yet so I cannot comment on it just yet but it might come in handy in the future. So all in all a brilliant machine and I recommend buying it now at this brilliant price.

There are other cheaper pressure washers about but they aren't going to be as efficient as this K4 Karcher model. It is a substantial beast and quite heavy so you need to be reasonably fit to deal with it. It came in a box and you have to assemble some of it which I had not expected. If you follow the pictures and the instructions carefully you should get it right but don't try and put it together without looking at the booklet. For instance you might not realise it is essential to pull the hose part through the side hole before attaching it - if you don't there will be an impossible coiled muddle. Once it is put together you can use either the single high pressure fitting that is suitable for paving/drives etc (though beware any loose grouting as it will take it out). Or use the adjustable spray head which sends the water out in a fan shape and can be used at hard pressure or dialled right down so you can do your car or garden furniture, or add a bottle of shampoo for instance to the dispensing part at the top of the machine. The wheels turn easily though you have to watch you don't get muddled up with either the hose or the electric cable. You can use it with an extension lead if you need to go a bigger distance though obviously make sure the extension is a safe one for outdoor use and not near enough to the water. The golden rule is that you must attach the water and turn it on before switching on the machine - you should never run it dry as that risks damaging the machine. I was quite cautious about this mix of electricity and water in one machine but it is superbly insulated and once you get cracking with it you won't want to stop!

Never used a pressure washer before so wasn't sure what to expect but this has done an absolutely brilliant job of cleaning the block paving in my front garden and pavement. I didn't have any detergent but all the dirt and marks came off extremely well without. I was loathed to use detergent anyway as the paving is so close to flower beds. Only thing was the setup. The instructions aren't that clear and when putting on the bottom basket/rack it wasn't easy to tell from the diagram that you needed to put the large plugs in then screw them in so I put a screw in first and it fell into the body of the machine and wouldn't come out so it's now rattling around in there for ever more! I'm now one screw short for the hose holder on the front so will have to nip to the DIY store to get one. Then I used the incorrect screws for the handle as again, the instructions aren't clear. I got there eventually but the instructions could do with a clearer explanation of the screws and other bits in the box. Having said all that, once it was set up I found it very easy to use and am very impressed with the result.

Much depends on how much you've paid for this! At full retail, from one of the big DIY stores, I suspect I'd be less satisfied than having bought it at the price I was able to on Amazon. It's replacing an old, well used 620 which was a rather good machine. Most aspects of it are good - I prefer the upright stance, it's light enough to carry fairly easily and the retracting handle is good. For for a mid range domestic pressure washer it does a decent enough job. Be aware that the lance needs to be close to surface like decking or slabs if you want to get good results. The cable tidy is a joke - a simple piece of netting! As to the hose tidy, they're having a laugh. The hose merely hangs off a hook - nothing wrong with that, but coiling the thing will drive you round the bend as it has me. For some inexplicable reason, the hose doesn't rotate within it's connection at the lance, so the hose is seriously difficult to coil as a result if you want to leave the lance attached. The hose can be removed from the handle, but why should one have to? The K5 has a proper reel, and while more expensive (and slightly more powerful) that really does make a difference. On reflection, I wish I'd bought it instead. As to the lance, I fail to see the need for the electronic pressure indicator. That's just a gadget. It would be nice if it came with a fluids bottle, Overall, it's ok and if you get it at a decent price then I'd say it's good value for money. If it last as long as the old 620 I'll be happy - that was well over 20 years old when it died.

I purchased this pressure washer to replace my old one which had stopped working. This pressure washer is well made, easy to set up and use. The different settings are perfect, each setting provides a perfect amount of pressure to carry out a variety of cleaning tasks. My advice would be at the start of a cleaning job select the lower pressure and work your way up to find the correct one for the job. I mainly use this for washing my car and was a little worried at first. You hear some horror stories about pressure washers and car paint work. However this was just what I needed. This pressure washer is great value and in the long run will save me money as prices for my local car wash have slowly started to increase. My only issue with this item is that the carrying handle is set to low. I recommend.

Had this pressure Washer for two years now and it is still going strong. I am quite surprised by the amount of negative reviews as like I’ve already mentioned, it has never missed a beat in all the time I have owned it. Easy to set up and use, I must use mine on average twice a month, mainly for the car but do all the block paving in the warmer months also. The hose has a decent length to it but would of been better if it had another couple of meters so the unit didn’t have to be moved whilst doing the car. One of the things that I do that has maybe prolonged the life of the washer is that mine is kept inside when not being used. The unit regardless of how it’s orientated after use does retain quite a lot of water. This is noticeable after leaving it a few weeks and when I come to use it again quite a lot of water is released from the hozelock attachment. The issue I believe many might be having is that storing this in a shed over winter, the retained water will freeze within the unit causing it to expand which might be the reason why some are breaking down. Personally I think it’s a great piece of kit.

This washer is perfect in every way. For any family size home and garden you get good power. The productivity gains from using the correct tool for the job is just amazing - literally does the job in half the time. Easy to assemble and most intuitive to use. There is a very sharp focus on superior fittings and accessories on this machine, there is a very robust feel to this top quality pressure washer. I am delighted with the product and more importantly with the results - every home should have this. A great piece of kit to have on standby and the on board storage means that it is ready to go, anytime and doesn't take up too much room meantime. Kärcher is the market leader for good reason.

My wife bought me this Karcher K4 as a replacement for our old one that had seen better days. I considered the Karcher K2 but after plenty of research and You tube demonstrations plumped for the more powerful (and slightly more expensive) K4 together with the T-350 T racer surface cleaner tool. Using these together with the Karcher stone and hard surface cleaning solution the results on our York Stone patio and drive are nothing short of amazing. Using the T-350 head eliminates all the messy unwanted spray that you get from using the 'wand'. Karcher claim that the T-350 it cuts the cleaning time in half. I can verify this is certainly the case, if not more so. The head effortlessly glides over the paving leaving the stones gleaming within minutes. You won't buy a pressure washer very often but if you get one of these you will certainly not be dissapointed. I can't wait to try it on the car later. The only down side, if there is one, is the instruction for assembly are not great but there are plenty of tutorials available on You Tube. Once you switch it on you will want to pressure wash everything in sight!
