Kärcher K4 Full Control Pressure Washer

UPDATE: Two years on and I have used the K4 for days on end without any issues. I had to buy another dirt blaster nozzle, but that was due to the amount of use it had! I think that this is a sturdy and reliable machine that is built to last. My old power washer finally started to play up after many years of hard service. We have a very large patio area to power wash each year. We are surrounded by deciduous trees and the patio is always green and disgusting after the winter. My old machine was not a Karcher, but over the years I found myself using Karcher accessories for it as they were better in every way! This prompted me to go for a Karcher model. I already had a T250 patio cleaning attachment so I went for this package. I have posted a full review on YouTube search for Russell Platten. The Full Control version has a pressure indicator on the gun and a lance, the Vario Lance, which allows you adjust the water pressure with a variable pressure regulator. The process of adjusting the pressure is a bit hit and miss, but very easy. Karcher recommend different pressure settings for different tasks to prevent damage to more delicate surfaces. As well as the Vario lance the unit comes with the Dirt Blaster lance which is more aggressive and a joy to use. The jet spins at high speed removing just about everything in its path. Using it fills you with pleasure as you watch your patio transforming in front of your eyes! We also have the Karcher T250 patio cleaner, one of the purchases I made for my old washer, and this speeds up patio cleaning considerably! If you have large areas to clean, the patio cleaner is a must! So we use the cleaner for the majority of the patio and the dirt blaster lance for the really bad areas. The washer has a built in detergent bottle cartridge slot on the top. This allows the use of various chemicals to help in the battle against dirt, mold and grime. It is easy to use with a dedicated setting on the Vario lance and a bottle that is just a push fit into the slot. The bottles can be refilled so you can buy one and then top it up with any detergent of your choice once it has emptied. Personally, I prefer the foam jet nozzle, you can get one that fits the new cartridge bottles or one with it's own bottle quite a bit cheaper here on Amazon. The unit requires a little assembly out of the box, I also have an unboxing and assembly video, this is pretty easy. The hose is 6m long and this can be a little annoying if you have large areas to tackle, I bought the 6m extension and this makes using the washer much better. It is a great machine, I have cleaned loads of different things with it and love it. However, there are two issues I have with the unit. The first is the hose, it is very stiff and the snap fit connections do not swivel. When you are using the washer, the hose tends to try and push your hand in a different direction and whilst this is not a big problem, it does get annoying after a while. If the hose was more flexible it would be better. The rigidity also makes coiling it to put away difficult too. The second issue only became apparent after I had used the washer for a prolonged period of time. The trigger is quite stiff, after a few hours of use your hand gets stiff and it becomes very uncomfortable. The tip of my little finger became numb and I have had aching hands after using it for several hours at a time. This is only a problem if you use it for longer periods, but it is an issue. The trigger needs to be softened! The unit is simply great! It is solid and has a good quality feel to it. It can tackle very large and dirty areas with ease. You can buy an attachment to allow it to be used with any water supply, such as a barrel or pond, beat the hose pipe bans! There are several models in the range, spend some time to work out which is best for your needs. Consider the patio cleaner, the K4 Home comes with one and is a good deal! You can't go wrong with Karcher, they are tried and tested, good quality machines. If you are considering one, go for it!

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!

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 reviewed this jet wash on you tube, there's a guy who does an excellent review, and having had Karcher products before went for the next level up from the one I had last....Boy i'm so glad I did, I wasn't disappointed it's great it does everything I needed, I have used it on my motorbikes (it can lower the pressure, the LCD control shows you) to our cars, the foamer you get with it is brilliant it is just like a snow foam gun (no need to buy another attachment as this does the perfect) it cleans the drive brilliant, just one thing that I didn't like was because of the power doing the driveway I always get wet legs, I did cure this and bought the Kärcher T 350 Wide Area Surface Cleaner this keep the over spray down and no wet legs.....all in all I love it.

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.

I have to admit I was cautiously optimistic when I ordered this machine. I have this phobia (or should I say "notion in my head")? that electronics, water and high pressure machinery do not make for a successful mix. And this had all three. Obviously my predicament was not helped by some of the negative reviews posted about the product. But despite the deep rooted cynicism, and the fact there are much much cheaper machines out there, I took the plunge and got one. In hindsight & reflection, I realize my main drivers for this purchase were: (1) My 10 year old machine (a Halfords branded one) was leaking so badly along the high pressure hose, it was getting out of hand. (2) This is the machine with the highest pressure (in bars) when you consider not having to fork out silly money (several hundred pounds) for a washer. Anything over 130 bar is priced so ridiculously, one would imagine there is a technical impediment to get any higher pressure. (Maybe there is - I just don't know it!) (3) The price of this machine has yo-yo'd quite a bit - ranging from the £140-ish mark to £220-ish. I purchased it when it was near the bottom end of this scale. Performance wise: (1) It is much smaller than I expected... definitely much smaller then my old one. And much lighter. But it does pack a punch... not to be understated. (2) I purchased this primarily to wash my cars - and one setting on the jet nozzle was good enough.. I didn't even give the fancy lighting system on the pressure gun a second glance. (A bit over the top - if you asked me) (3) I am one of the pickiest car cleaners imaginable - so from the onset I did not use the inbuilt detergent dispenser system, partly because I was not confident that Karcher's own detergent had any decent rankings in the car shampoo leader board; and partly because I'd rather wait a bit to recover financially and invest in a proper foam dispenser So... Is its performance any better than some of the cheaper models out there? Not sure.. Is its durability worth the price? Only time will tell... Am I happy with my purchase? Hell - Yes! Cleaned out two cars in no time - results are spectacular!

un detalle: la clavija no es la europea sino la británica y ha habido que comprar un adaptador
