- Hi Guys and welcome to my test and review of the Karcher K4 Full Control Pressure Washer and Accessories (sold separately). I've been using this Pressure Washer for about a Month and thought a quick review would help you if you're looking to buy.
I've also included my review of the Karcher Car Shampoo, Karcher Ultrafoam and the Karcher Soft Brush Attachment.

Thank you fantastic demo! I bought my karcher K4 4 years ago and only took it out of the box today
@@The_Invisible_Self I have to admit I am very impressed it’s worlds apart from my previous washers.
It’s well built and easy to use.
Thanks for the review. After watching it I bought one. One tip which I saw you doing is not to get the nozzle too close to the path/whatever. I did, with a K4040 and it developed three/four kinks in the hose from the washer eventually causing a blowback and a major leak under the machine. Out it went, but no problems with the K4.
Great news buddy. Shame about the 4040.
Swirl marks for days using a brush on your beautiful Mercedes. Great video mate, thank you
Brett Ian Smith no worries mate and you’re right swirl marks for ever!
Thanks for review. Not sure laying the brush attachment on the ground before you clean your car with it, is the best idea though. All you need is a small bit of grit on the brush to add a new effect to your paintwork.
That was a great review. I washed my car with one of these this morning, well pleased and might buy one myself.
Second one is the dirtblaster, it is meant for the hardest work that's why you shoudn't use it for every surface. I would recommend only using it on hard surfaces like stone, for others like wood or your car i would use the otherone and change settings depending on the surface ;)
Really helpful, thank you, particularly about the brush attachment. My back wouldn’t cope either so that has saved me the expense, I have a shed full of ‘useful attachment’s’ for various products which all looked fit for purpose at the time. Keep it up.
No problem buddy. I'm glad the vid helped and thanks for commenting
Was interested how the top soap dispenser on the Karcher worked and had me intrigued up until the point when you put the soft brush on the concrete then go straight up to your nice Mercedes and start washing it. Grit in the brush will do no end of damage.
I bought this model just before Christmas 2019 used it once worked fine, a couple of weeks later tried using it again, no pressure what so ever, had to send it back to Karcher as B&Q would not give me a refund nor would they exchange it for another. Karcher did repair it and it works fine now after replacing several parts.
Nightmare mate thanks for sharing. Good to know.
I was loathe to buy Karcher ... after buying their awful window cleaner device . When it packed up after a short time I read the reviews / comments and realised what bloody awful after sales service Karcher have got . Amused me when I read that it should not be kept in a damp environment ,, It's made for cleaning shower screens for god's sake ! Haven't used my K4 yet ... but fingers crossed .. Supplied by Tool Station , here in France ... so hopefully , better customer service if it goes wrong !
I had same problem no power after trying to use it yesterday no power. Took it back to Halfords who exchanged it for updated version of this washer
Can’t believe you dropped the brush on the ground then proceeded to clean the car with it
Lol
Cant believe he washed his car with a brush… and its a mercedes to😂😂
🤣👍
Excellent video...very well explained and balanced. Appreciate the time you took putting this together. Thanks 👍
No problem buddy, thank you for watching/commenting
This is so therapeutic to watch
If you liked that, you'll love this...th-cam.com/video/6G46mGu066o/w-d-xo.html
Nice vid ! I suggest using a telescopic handle with a soft brush, waaay better for your back.
Oh, and use 2 buckets, one with a grit guard with water ( rinse ) and one with water and shampoo ( clean ). Dry with a good microfibre towel. I also like to use a shampoo & wax combo.
Thanks for your vid, keep it up ! 👍
Totaly agree. Foam gun simply does not work to remove road film. Soft broom and bucket of TFR. Thers no easy fix.
Is that the fault of the gun or the foam product? My friend uses a foaming product made for trucks etc and he never has to use use elbow grease.
Great video. I bought the k4 with the home it a few weeks ago and I did my driveway with it, great product. Just got the car shampoo yesterday so must try ot over the weekend. Great tips.
Kevin Caplice great stuff mate. Glad the vid helped.
Great Review thanks, ordered mine direct from Karcher.... Extra year added to guarantee when ordered direct :-)
You';ll need that extra year, I promise you - good luck!!!!
Brush placed on the ground and then used to scrub the paint work...Oh dear!
I’m a GSXR man too and just bought a K4 Karcher (to wash my K7 GSXR) 🤣👍
Just both K4 full control, thanks to this video I know how to use
For the car wash the water nozzle should be set to flat, it does a better job of removing the soap in a much neater way.
Excellent review was just debating which pressure washer to get and the K4 was the one of choice. Nice one
Thank you ,great video ,it's a sunny day here in Dublin so hoping to buy one today or tomorrow and get started on the driveway
Great informative video, love the bike, always been a gixxer fan and had a k3, absolute weapons
Nice one buddy!
Came for the karcher review, stayed to admire the bike, top review though nice one!
Thank you mate. Bike is over on my other Channel: MotovlogUK
@@TheThorpester will be checking that out then!! Thanks very much
Thank you for all your trouble. Super video. I will be using my new K4 in the next few days - with greater confidence! Look out you dirty paving slabs!
Haha nice one mate. Mines still going strong!
great vid, cheers. sold !!! i,ll be getting one soon. hope your being sponsored by karcher for this.its well put together and presented. nice bike too fella
Thanks mate and no. Unfortunately Karcher don't sponsor me lol
Thanks for the video, I buy the K4 premium power control too. Greetings from The Netherlands
Greetings buddy and thank you for watching
Snow foams done a terrible job!! Would suggest trying polar blast autoglym with a diff nozzle 👌🏼
Yep karcher snowfoam and nozze is crap quality. I use meguires
Why is everyone using a separate detergent bottle, I plugged my bottle into the unit but wasn’t sure if it was dispensing, I assume it is just plug in and go, have you used it plugged in?
That was very detailed review, very helpful. Thank you for posting it.
My pleasure!
Just use the brush for the rims not the car😁
Great video, I will be buying one tomorrow can’t wait to use it 👍👍
Thank you mate and all the best
The only problem I can see with this is the handle gets put down on the floor quite often and having the LED display on there it may get damaged easily.
First proper decent review. Good job
Thanks for this review, need one of these for my motorcycle
Yea baby! Look here: th-cam.com/video/6G46mGu066o/w-d-xo.html
I is my recycle centre full of Karcher products. Sounds like they have a staying power problem. Cannot take the pressure?
Second Kärcher and like how many hours does somebody wash stuff and tiles at home? The unit (now the capacitor, seemingly) often breaks down. Such a shame because the rest seems like a solid build quality. To me it is a big pain on just getting the (2018) capacitor out of the unit, seems stuck. Why why why? My central heating pump is running 20 years, EVs drive 150000km without issues. Kärchers only x hours .... ? or just me? What are your experiences? Mine is now taken apart on my garden table - capacitor stuck, what a mess, didn't clean anything ... seems like a consumer - market choice that stuff needs to malfunction. What would be a better power cleaner than my K4, a durable one!
I wish someone would tell me how to insert the container of l cleaner into machine itself. How do I open the lid , how does it go through the machine? Thanks😅😊
Hope it lasts longer than Karcher i had. I did not use mine more than once every 2 weeks on the car. Dead a few weeks after the warranty ended. They were not helpful at all Basically I was told to go away by saying i need to get it repaired at a local repair agent at my cost. No chance of a contribution towards the cost.
That's good info mate. I'll have to see how this one holds up over time. Not sure on the Warranty I got so I'll check it out.
The pressure washer itself is good the accessories are not, go for aftermarket alternatives. Putting the “ soft brush” on the tarmac before rubbing it all over the car is just asking for trouble!
Thanks for the video. Just going down to buy one now. There may be questions. :)
Haha no probs matey. Fire away
Some say you have make sure the water is coming through before you switch it on,, but i never do and if it has no water the pump cuts so no harm done
I liked the music . Give the DJ career a chance mate 😅
Very helpful demo. Thanks!
Hi. Thanks for the review but I'm having issues with mine. when i turn it on and press the handle the pressure keeps fluctuating from mix-low-mid-hi back and forth. Can't get it to stay on on a particular pressure.
Enough pressure coming from the Tap? Is the wand twisted on the handle all the way. Is the Wand blocked up with anything. Some things to check mate but worth calling Karcher I think.
@@TheThorpester yes the wand twisted all the way, same happens with the spiral wand, just can't maintain a particular pressure. Guess I'll just have to call Karcher.
@@peterlui3561 yea give them a call mate. If you have enough water entering the unit from your hose you should be good.
@@peterlui3561 Sounds like an airlock to me. You might need to release that by running the lance with the machine off first, once it's filled-up
Thanks for that.....off to Argos
Is the Ultra Foam 3 in 1 Wash safe for ceramic coating? Many thanks!
How do despense soap
Teach me please
I bought some 2 weeks ago
If you have the correct Soap container, it goes in the slot at the top of the unit. Once the Soap container is installed (and has soap in it) you just turn the Wand on to a low setting and you should see MIX light up on the Wand handle. If you're putting the Soap Spray Gun on the unit it just replaces the Wand as seen in the vid. Hope that helps.
Do you have to use the Karcher detergent in a special bottle? If you wanted to use another product would you need to decant into an empty Kartcher bottle
I think you can get other ones but they need the right end on. I got the Karcher ones so they can be topped up when empty by any other shampoo
How's this jet wash going a year later. Am looking for a mini jet wash at the minit
Still good buddy I still use it after every ride. Works fine.
Very good demo, very helpful thanks.
You are welcome!
Good video for advice. One point. Never put the brush on the ground! You'll pick up dirt and scratch the ..ck out of your paintwork 🤦♂️.
i just saw that....
Very informative video thanks. Just wondering about the shampoo and other bottled products, I assume they have some sort of valve on the top so is it would be possible to reuse them with other brands of cleaning products?
Thanks mate and yes, I do exactly that. When the bottles are empty I fill them with stuff of my choosing (usually Halfords own brand Shampoo)
@@TheThorpester that’s good news, thanks for quick response 👍
Thanks for the review. Does the yellow hose pipe come with the Karcher and if so, how long is it?
The yellow Hose pipe is my own regular one. You'll need to get one if you haven't got one to get the water from the tap to the Jet Washer
Does the machine stop and start ?Does the machine carry on running when you’re not got your hand on the trigger ?
It stops and starts as you use the trigger
wouldn't use the brush on the bodywork.blimy
Definitely not. I have one I have never used. The bristles are way too course. I wouldn't even use it on my alloys as my alloys on my mini cooper s are 2 tone and diamond cut
Hi i have one but its presure gone.i don't know how to fix it
I have heard that you should not use a power hose on a motorbike, I use a sponge on mine and just use a hose to wash the suds off
Why not? Decals have a clear coat over them (shouldn't come off) but I agree, I wouldn't jet the engine bay etc. I only use it to rinse off the soap and don't get too close.
You are spot on.wheel bearings brake seals..and above all cdi canbus electrics are all weak points
How dare you scrub the car with a brush!!! Unbelievable
Lol. It's a lease. It's fine ;)
Thats what I was thinking
@@TheThorpester 🤣🤣🤣🤣😂
Hi TheThorpester, thanks for the video. I am thinking to buy this unit but am unsure about a point, please see if you could help. The intention is to clean house/building walls using K4, how good it is to clean painted walls, and how high the water could go? Would it cover a two-story building with sufficient pressure to clean the high-reaching areas such as the eaves? Many thanks
Hi buddy. I don't think it's suitable for that mate. Pressure would be fine but you'd have to get it up there. The other Wand that I used on my slabs might do the job but I'm not sure sorry.
@@TheThorpester aha, thanks for the help and the quick response
@@sslalaninz Sounds like you need a Karcher Ladder mate
Do you have to have a hosepipe and constant water source plugged into the washer? At all times? Or does it store some on board?
Yes you do. You need a Hose to feed it the Water it needs
You can buy a 200l water container with hose for your water supply but thats just pointless if you can use a hose buddy
Thank you for the detailed review.
You're welcome buddy
Do you use hot or cold water when washing the vehicles? Very helpful video. Just got a K4. Thanks.
Hey buddy nice one. I can only run cold through the jet wash but I use very hot water in the bucket.
@@TheThorpester Thanks for the reply. Do you mean that the machine is not capable of taking hot or warm water - or do you mean that you only use cold water due to your personal situation or by choice? Regards.
@@TheIrishMegaphone I only have a Cold Water Tap outside so I use that. If you have hot water then I suppose it would be fine as long as you have the water pressure
@@TheThorpester Ah I see. Thank you.
Cold water is fine for car washing, car shampoo is designed for cold water and the only real benefit to using warm water is to keep your hands warm on a cold day. You should never use hot water through a pressure washer as the water going through the machine is also used to cool the motor and the compressor is not designed for hot water either.
Still deciding between karcher & Bosch
I have used both and they are pretty much the same performance wise. I personally prefer the Karcher because 3rd party accessories are easier to find for Karcher.
Nice video, how is it after a year now? I am tempted to buy one but everyone on Amazon reviews is saying the motor fries easily and giving it 1 star reviews?
Hey buddy. I bought it because it had good reviews so not sure what's happening there lol. It's still working fine although swapping the lances over is much more difficult these days. Don't know why but it's much harder to twist them on. Probably wear and tear as I do use it a lot. Motor seems fine and I did my whole Driveway with it last weekend. Had it running for about an hour.
@@TheThorpester nice, thanks thats good to know.
Hi mate excellent vid. Im looking to buy a k4 is there a difference in power control vs full power control ?
I'm not sure mate sorry
Nice overview, did you try it with hot water? Any thoughts on hot vs cold?
Thank you mate. No I didn't try it with Hot water. I expect it would be better if you have the facility to do that
Any advice for when the detergent doesn’t come through?
Not sure mate. Are you using the bottle that fits the mount on top? If so, have you unsealed the bottle and checked the ends not blocked before you pop it on? It should go into 'MIX' mode when the bottle is on and you pull the trigger. Does it do that? Have you tried twisting the wand down to it's lowest setting with the bottle on? Power is on? Hope these suggestions help.
Can you re-use the shampoo bottle - fill it back up once used?
I do mate. I just put some cheap stuff in there. Works well.
@@TheThorpester perfect, thank you
HI, I have difficulty getting water from my driveway. Can I use a suction hose to get water from a bucket?
Thank you
Useful video thanks. Had one for a while but will be doing patio in the coming weeks. Is the second wand the "Full Control Dirt Blaster" DB145 as on their parts website?
I think so mate. Looks exactly the same. Would take your skin off lol. Patio will be gleaming!
@@TheThorpester Thanks 😆
Do not use that brush on your car it destroys your cars paintwork do not use it on your car. Anyone who has used it on a black car will tell you how much it puts small swirls and scratches on your paintwork
Very true. Also never use anything that's been on the ground (or anything dirty) touch the cars paint, that's a one way trip to swirl city.
That Home and Garden app is really BS! I tested it out for a k4 full control doing a car, it said i first rinse it down, bottom to top?!?! thats was already weird. Than it showed i still should hand wash the car.... why then get a pressure washer?
That is weird. Haven't seen the app. I use it to blast the road film off, then cover with soap. Then i hand wash with sponge then use it to rinse. I also use it to clean the slabs etc.
Totaly agree. What's the point if you need to hand wash the car, sno foam Pro is only a pre wash ??? You then need to wash it with a sponge or long handled brush. Total waste of time and money if your using it to wash your car. Great for concrete thought.
Great video, just bought this all. Quick question, how much of the shampoo was used whilst you were using the brush on the car? Some people seem to say it drains the shampoo pretty quickly.
Nice one. I figured out that by the time you get to using the Brush and Shampoo, the car is already wet so you only need to squeeze the trigger periodically. I squeezed it once on each panel (to get a bit of shampoo out) and used the brush to move it about and clean the car. Hope that helps. It will drain the whole bottle if you just keep the water coming out while brushing.
@@TheThorpester cheers mate will defo give that a go
I found with my K2 that the 500ml continer it came with, with the spray foam nozzle. Is usually enough for 1 motor, I found this to be the case with both the Autoglym snow foam and Karcher's own brand too.
If you can’t regulate the shampoo then you have to ask what is the point. Mine virtually drained the entire bottle in one wash - and I kept pausing it.
@@mikeattard3657 I'd suggest getting the separate foam nozzle attachment in that case. That way you can do it in increments of 500ml at a time
Great review thanks 👍😊
Is the hardest setting on the adjustable end safe on car paintwork?
Yea it's fine mate. I don't go too close to the Paint just in case. Just don't use the other wand that I used for the Slabs. That would strip your Car no problem
@@TheThorpester Cheers for the reply. I wouldn't even think about using the other wand on a car haha
I have one and im sure it says in the instructions not to use it on the hardest setting on the adjustable wand. And to only use it on the car setting.
having difficulty in removing the wand to change to dirtbuster or T Racer. any suggestions appreciated
I have that same issue sometimes. I found that pushing in real hard as quick as possible and twisting works sometimes.
Try putting a smear of vaseline when apart
@@TheThorpester wd40
Is the preasure washer still going?.TIA
Yea all good mate. Used it yesterday
Any problems getting the shampoo to come through when using the plug in bottle?
I do its more water than sope
I did at first buddy. When the bottle is in, you need to set the pressure as low as possible by twisting the wand. The 'Mix' light should come on
How long is the hose from the unit to the gun ?
6 Metres
@@TheThorpester option of 8 meter lance
what is the music used in the video
I made the Music myself
Well done great review 👍
Cheers buddy
I'd b really scared of the brush scratching paintwork
Yep, would never use the brush one, 2 bucket method at least to avoid swirls/marks etc
Polar wash set with a contact wash is the way to go with that pressure washer
I cannot attach the lance to slab connector
You sorted it pal? Take off the other lance and push and twist the slab one onto the handle
No, I had to use the one from my old K2,
@@winsumwright2321 send it back!
the shampoo on the car did just nothing. There is a mondial problem with these bottles.
Great review
Great review 👍
can these shampoos be refilled somehow?
Came here looking for that
Yes you can pull the top off and fill with whatever you wish
are you the voice of Racer TV ?
No sorry. Don't know what that is.
what's the noise level? not so "full test" then
It’s loud. Would you like me to tell you the shade of yellow paint also?
@@The_Invisible_Self lol. Now that I can do ❤️
song at 2:56 ??
Its a Tune I wrote for the vid
@@TheThorpester Oh okay, its really nice
Hi, would you like to review the new MJJC foam lance Pro?
I'd love to. How would I do that then?
@@TheThorpester hi, i just emailed you, could you please check it? thank you.
search pan the organiser
I found with the mix bottles they don't last long, it soon drinks the bottle and @ £7 a bottle it gets expensive so i only use it for cleaning and rincing atm
Karcher snow foam and car shampoo is crap quality and very expensive like u say
@@karlpeart1752 yea i filled a bottle up with water and you could see it soon empty so I'm not spending that much on a bottle because id need 2 to wash my car lol
Never use any brush on your car paint
Quite right .. The brush will always retain dirt and grit .. all you are doing is spreading it over your car . ! Jet wash , snow foam .. jet wash and take water off with good quality microfibre cloth
Why not? I had an Audi A4 for 4 years (new company car) and I jet washed it at work and used their Brush and Suds to scrub the car twice a week. Still looked brand new when the Lease ended. As long as you blast the dirt off first I can't see any difference between using a brush or sponge.
@@TheThorpester you know maybe you are right but I don't like to use brush I think it's aggressive on the paint
@@saleh-sn2ez Don't get me wrong. I normally wouldn't use a brush. I'd usually use a sponge and microfibre cloths etc. But for this Vid I wanted to demo the Brush. Good for Wheels but that's about it I think. The Brush I used on my A4 was a broom type brush specific for the task so very soft and it was ok. Just didn't get in all the places.
@@TheThorpester got ya
How this really work
Let me ask do I have to have tithe handle up to it to work
No you just connect the water, switch on and pull the trigger
Nice bike!
NEVER clean a car with a brush
