Thank you fantastic demo! I bought my karcher K4 4 years ago and only took it out of the box today

Just both K4 full control, thanks to this video I know how to use

That was a great review. I washed my car with one of these this morning, well pleased and might buy one myself.

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.

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.

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 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.

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.

Very helpful demo. Thanks!

Excellent review was just debating which pressure washer to get and the K4 was the one of choice. Nice one

Excellent video...very well explained and balanced. Appreciate the time you took putting this together. Thanks 👍

Great informative video, love the bike, always been a gixxer fan and had a k3, absolute weapons

First proper decent review. Good job

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

That was very detailed review, very helpful. Thank you for posting it.

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.

This is so therapeutic to watch

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 ;)

Swirl marks for days using a brush on your beautiful Mercedes. Great video mate, thank you

Great video, I will be buying one tomorrow can’t wait to use it 👍👍

Great Review thanks, ordered mine direct from Karcher.... Extra year added to guarantee when ordered direct :-)

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!

Thanks for this review, need one of these for my motorcycle

I’m a GSXR man too and just bought a K4 Karcher (to wash my K7 GSXR) 🤣👍

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.

Very good demo, very helpful thanks.

Thank you for the detailed review.

Thanks for the video. Just going down to buy one now. There may be questions. :)

Great review thanks 👍😊

Totaly agree. Foam gun simply does not work to remove road film. Soft broom and bucket of TFR. Thers no easy fix.

Thanks for the video, I buy the K4 premium power control too. Greetings from The Netherlands

Came for the karcher review, stayed to admire the bike, top review though nice one!

Great review 👍

Great review

Thanks for that.....off to Argos

Thank you

Can’t believe you dropped the brush on the ground then proceeded to clean the car with it

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

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.

Brush placed on the ground and then used to scrub the paint work...Oh dear!

Well done great review 👍

Just use the brush for the rims not the car😁

Is the Ultra Foam 3 in 1 Wash safe for ceramic coating? Many thanks!

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!

Snow foams done a terrible job!! Would suggest trying polar blast autoglym with a diff nozzle 👌🏼

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?

I liked the music . Give the DJ career a chance mate 😅

Polar wash set with a contact wash is the way to go with that pressure washer

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 is my recycle centre full of Karcher products. Sounds like they have a staying power problem. Cannot take the pressure?

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 for the review. Does the yellow hose pipe come with the Karcher and if so, how long is it?

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.

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😅😊

Hi mate excellent vid. Im looking to buy a k4 is there a difference in power control vs full power control ?

Hi, would you like to review the new MJJC foam lance Pro?

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

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

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.

Hi i have one but its presure gone.i don't know how to fix it

Still deciding between karcher & Bosch

How's this jet wash going a year later. Am looking for a mini jet wash at the minit

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.

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?

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?

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

Nice overview, did you try it with hot water? Any thoughts on hot vs cold?

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.

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 🤦‍♂️.

How do despense soap Teach me please I bought some 2 weeks ago

Nice bike!

Any advice for when the detergent doesn’t come through?

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

Do you use hot or cold water when washing the vehicles? Very helpful video. Just got a K4. Thanks.

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!

Can you re-use the shampoo bottle - fill it back up once used?

How this really work

Is the hardest setting on the adjustable end safe on car paintwork?

Does the machine stop and start ?Does the machine carry on running when you’re not got your hand on the trigger ?

Any problems getting the shampoo to come through when using the plug in bottle?

wouldn't use the brush on the bodywork.blimy

Is the preasure washer still going?.TIA

having difficulty in removing the wand to change to dirtbuster or T Racer. any suggestions appreciated

are you the voice of Racer TV ?

How long is the hose from the unit to the gun ?

Storage for the power cable and the hose does not look that good but looks a decent product over all.

HI, I have difficulty getting water from my driveway. Can I use a suction hose to get water from a bucket?

what is the music used in the video

can these shampoos be refilled somehow?

I'd b really scared of the brush scratching paintwork

How do I connect to an indoor tap

I cannot attach the lance to slab connector

song at 2:56 ??

Couple of things, never use one of those brushes on a car, they cause tiny scratches in the paint, the snow foam attachment that Karcher sell is ok but not great, there are much better 3rd party snow foam lances available cheaper that produce a much better foam and also the Karcher brand shampoo is also not very good at all and is very expensive for what it is. The K4 is a great pressure washer though, have one myself and it's been a workhorse. Totally agree about only using the variable lance dialled right back too as the others can damage your paint.

How’s it now

Let me ask do I have to have tithe handle up to it to work

How dare you scrub the car with a brush!!! Unbelievable

what's the noise level? not so "full test" then

NEVER clean a car with a brush

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
