Other than getting the hose connector turned around (watch out for that one), the machine is simple to put together and use kzfaq.infoUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP . And very nice, too. I'm surprised at the power-it's more than we'll ever need, and we've not even used the most powerful setting yet.I've cleaned off a dirty concrete porch to get it ready for sealing, started to clean siding, and I know this pressure washer will be terrific for cleaning tools this fall.The only issue we had is we had turned around the hose connector, and it leaked. Once it was on correctly, though, we had no problems with the connection. Just remember that the end with the green knob goes towards the hose. It's obvious now what we did wrong, but not necessarily obvious at the time.

Thanks for a fab review, I have watched others but found your review the most helpful, thank you

Have to say this is the best review on the Karcher on KZfaq. Nicely explained and demonstrated. Thanks pal, very much appreciated.

Hi Russell, great review mate. You pretty much covered all that is important for someone wanting buy this Karcher 4K unit. I just picked one up from me local hardware store 'Bunnings' Australia. Early 2016 Xmas present from me lovely wife. Been wanting to buy one for awhile but couldn't decide on which unit 3k, 4K or the 5k. Went for the mid range 4K. Not too cheap or not too expensive. I like how you started with breaking the unit in, then wash the paving, outdoor furniture & finally the car. I wanted the unit for all those reason. Also the 4K comes with the domestic use 5 years warranty in Australia too. Karcher should be grateful for genuine customers like you with honest review. Because you just sold few more units for them. Thanks mate!

Thank you for taking the time to explain how assemble and operate my Karcher K4 Pressure Washer, I used to have a K2 and and used it constantly for all types of Jobs Patios, Cars Decking, Fence Pannels and many more Jobs as you did I found if I didn’t Leather the Car off it would leave Streaks then I started using filtered Rain Water and it seemed to eliminate the problem👍

Really useful demonstration. Liked the attitude of the presenter. I learned a lot, I’ve bought one - now for action!

A really good review, nice to hear a Yorkshire accent and not an American.

Fab review Russell.. I bought one today there on offer today at wickes .. for the sake of moving the machine a few times outweighs having to look at a dirty backyard .. cheers, james!

I was very confused will all types and specs but, now I have seen your video, I ordered my K4 with patio cleaner. You deserve a big thank you for the effort you put in this video to help people understand what they want to buy and make up their mind.

Great review Russell. Price in the UK has come down to 189 on amazon with the patio cleaner and foam nozzle, ordering shortly!

Great review, thanks for taking the time.

A very good review. Now I know I have to buy the K7 for sure. Much more power.

Cheers mate, found this very helpful and actually see what impact the K4 has

Thanks for the great clear review, this model seems perfect for me. Going to buy one right now ;)

Really well explained. Took me ages to find a good video to explain how to use the settings thank you 🙏

The best k4 review on KZfaq

Mines arriving today :) can’t wait! Always wanted one

Great Review, Thank You For Your Time!

Brilliant review here. Thank you so much.

The only good and useful review of K4 on KZfaq. Kudos to you Sr.!

Very informative video thank you - I bought my K4 today.

I just bought mine, good video! One thing though use a wash mitt for the car not the brush :)

Great review, thanks. Made choosing much easier

Been looking around for the last couple of weeks for a decent pressure washer as at the minute I'm using a petrol one which is too loud and a pain in the orifice to set up especially when you run out of petrol great review you I am definitely going to get the K4 now I've seen you use it thank you my friend great description👌

Great video. Thank you. Your video is very informative and very helpful. 👍

Thanks for a great review.. was thinking of the Karcher K2, but after watching your review, look like the K4 Full Control is well worth paying the extra for..

I just set up my Mothers new Karcher K4 Full Control, very easy to set up, I didn't realise you'd need to buy a seperate hose 'adaptor' to keep the hose on the unit though 😑. Another trip to the shop. 🤐

Great review, thank you.. you’ve made my decision to buy the K4

Good review mate especially the hose length part not many people factor this in when they buy.

I used my Mothers the other day for the 1st time in ages but the foam didn't come out for some reason, I did push it in, I will try again but an idea's why?

a very detail explaination how to use the level pressure. thanks!

Thank you this has been a great help.

Top man. Many thanks for this vid

Best review..just bought one today..many thanks...

Great review after searching through loads think ill be ordering k4 2moro it was between the k4 and k5 and think this is more then upto job ,, hope your misses had you a big bacon sarnie and cup tea after all that work 👍😆☕

Brilliant Vid. I want to purchase one of these but don't have an external tap?? Is there any way to run this from my kitchen tap with a long length of hosepipe which I already have, Thanks.

Great review and demo. Thanks.

I had an old karcher 411 machine from 1999 and it still works but I invested in a k2 premium car and home machine and it is the best investment I have ever made. It is more than enough for my needs

Thanks for this I’ve just bought one from Halfords £150 - you have a nice place there

Nice review, thanks. I've made up my mind to get one of these units now.

Thanks for a. Good review gonna ordered 15 mtr rubber hose. Just hoping it won’t loose power over 15 Mtrs

Really good video, I bought my yesterday time to try

#karcher i think you owe this man a book of vouchers or the latest k7 to keep and review for you ,,he must sold you a lot of units ,this is what customers look for in a review a good honest review from a down to earth guy beets all your big budget fancy advertising videos any day ,, and big bunch flowers for his wife in helping in this ,,👍👌

Nice review , really helpful .

Can you tell me where did you find the other hoose that you connected to the water tap ?

Real life review, like for that

Great review I'm looking at getting the one your doing the review on to use for my mums garden then the back garden we are renting then onto the drive in the house in Brittany 😬 if you ever need a hand with your BBQ on a nice sunny day let me know 😁 you have a nice looking place pool as well again thanks for your time 👍🏻

Cool video, nice table too :-)

Thanks from New Zealand

Great review 👍

Loving the birds

Great review bro.

Thanks for this video. I now know im not buying one of them. The decision was made when you had it on 'hard' but was holding the lance with one hand at arms length.

Brought ones of theys with the Suction hose so it can suck the water out of a bucket, water butt etc, quite a good review straight to the point no mincing about You've earn a sub off me

Nice one. Jest bought one after seen this . Thank you sir .

Great video

great review, thanks a lot! The karcher k5 has a 8m hose instead of 6m, do you think thats a significant upgrade, or is 8m still not enough to do the jobs comfortably?

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

I work for a hardware store and have to say the few we get back with faults Karcher are very fast picking up and returning fixed ..... after sales are brilliant ...

Great review just one question, where did you get the 6m hose extension from ? I have looked at the Karcher site and not found any reference

Did u source a cheaper supply of detergent I’ve done the same but the bullet and bought Karcher one with the intention of filling it back up with cheaper stuff.

Great review, I'm thinking about one of those :) Btw you've took "vast majority of the dirt off" along with quite a lot of your cars paint clear coat. That scrubbing technique is good for washing dishes, but not for your paint job. Next time please stick with the power washer and contact-less wash, you will save some money for paint correction :D

I cried for the car when you took that brush to the paintwork😂😂

Thank you, dear sir!

Sold👌

The detergent bottle you refill with one of your choice, yes? For the stone and facade cleaner I assume the same applies. Is there a suitable stone/patio detergent out there?

Hi Would very much appreciate advice on how to clean staining from bird droppings. I have a Portland stone patio, very light and porous and the stains are brown and stubborn. I’ve tried washing up liquid mixed with bleach. It moves light staining but not the dark heavily soiled areas. Ive tried undiluted bleach, which discoloured the stone. I’ve tried karchers stone cleaner, no movement. I feel I want to buy a shotgun

Hi Russell, Great honest review. I've now bought a K4 after watching your review and I'm wondering whether you use the universal detergent for most things; car, patio furniture and patio area or do you swap the detergents in the bottle, depending on the job you're doing?

Tak fordi du har sendt en god idé.

Great review! Helped me decide which model to go with! Would recommend you use the snow foam lance for the car with a generic snow foam solution, I bought one to use with a Halfords brand foam solution

K4 is best overall washer price and performance vise I think. I have a K2 only and hopefully to upgrade one day

can be use it for big machines for professional use?

The model of the t racer that you have is t300 i have this with my k7.91

Hi Russel, I’ve just bought the K4 today I’ll probably wait until the weekend to use it, but I found your video very useful as I’ve never used one before. Just one question I might be daft but I haven’t opened mine yet do you get the hose that you attach to the kartcher or do you have to buy a separate hose. Sorry if that sounds daft but it’s all new to me. Thank you for a well constructed video.

Very useful! Thanks for the video. Is there a chance of doing damage to a patio or driveway? For example, in between bricks.

hi Russell, very informative review you have put together, are you still using the K4 or have you upgraded ? thanks.

The plug and play bottles can you just refill them with a diluted mix or can you do a neat mix through it ?? Is this as good as getting a bottle what goes on the end of the lance?

What happen to your Bosch Aquatak 1200 Plus? Still working?

Nice house.

Thank you 🙂

Hi Russel, Thanks for a very informative review of the K4, just what I was looking for, I have it down to this and the wilks rx525, having had the K2 for all my pressure washing needs( I have had 2 of these, which have fixed a few times till the pump goes, I gauge this as time to by new) at the moment the Karcher has the win only because I have user knowledge of Karcher. I don't know if you looked at the Wilks as you made your short list too ? any info if you did would be of great help before I finally decide...…………..Again Many Thanks Russell

Hi Russell, for the Karcher K4 model featured in this video, did you encounter any malfunction of the equipment to date?

Hi Russell the lance and handle when connected looks shorter than the average power washer lance , do you get a bad neck/ back after an hour or so because of this ? Cheers Johnny

Why do you have to run the water first before turning machine on?

Brand new in screw fix today £159.99 i had a voucher code for discount. I'll try it in the morning

Bro i have 1250 meters squer house the k7 is the right for me

How do you connect two 6 meters hose is there hose joint accessory?

Any car detergent will do ?

my gun wire pops out from the machine once I out the power on, do you think I am missing a part ?
